IT outsourcing can be implemented both ways: outsides or within the country. \r\nIT outsourcing vendors can provide either a fully managed service, meaning they take full responsibility of all IT maintenance and support, or they can provide additional support for an internal IT team when needed, which is known as co-sourced IT support. A company using IT outsourcing can choose to use one provider for all their IT functions or split the work among multiple providers. \r\n<span style=\"font-weight: bold;\">Specific IT services typically outsourced include:</span>\r\n<ul><li>Application development</li><li>Web hosting</li><li>Application support</li><li>Database development</li><li>Telecommunications</li><li>Networking</li><li>Disaster recovery</li><li>Security</li></ul>\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">Reasons for Outsourcing</span></p>\r\n<span style=\"font-weight: bold; \">To Reduce Cost.</span> More often than not, outsourcing means saving money. This is often due to lower labor costs, cheaper infrastructure, or an advantageous tax system in the outsourcing location.<br /><span style=\"font-weight: bold; \">To Access Skills That Are Unavailable Locally.</span> Resources that are scarce at home can sometimes be found in abundance elsewhere, meaning you can easily reach them through outsourcing.<br /><span style=\"font-weight: bold; \">To Better Use Internal Resources</span>. By delegating some of your business processes to a third party, you’ll give your in-house employees the opportunity to focus on more meaningful tasks.<br /><span style=\"font-weight: bold; \">To Accelerate Business Processes.</span> When you stop wasting time on mundane, time-consuming processes, you’ll be able to move forward with your core offering a lot faster.<br /><span style=\"font-weight: bold; \">To Share Risks.</span> When you delegate a part of non-focus functionality by outsourcing it to a third-party vendor, you give away the responsibility and related risks.","materialsDescription":"<h3 class=\"align-center\">What are the Types of IT Outsourcing?</h3>\r\n<p class=\"align-left\"><span style=\"font-weight: bold; \">Project-Based Model.</span> The client hires a team to implement the part of work that is already planned and defined. The project manager from the outsourced team carries full responsibility for the quality and performance of the project.</p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold; \">Dedicated Team Model.</span> The client hires a team that will create a project for them, and they will work only on that project. Unlike the project-based model, a dedicated team is more engaged in your project. In this model, an outsourced team becomes your technical and product advisor. So it can offer ideas and suggest alternative solutions.</p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold; \">Outstaff Model.</span> It's a type of outsourcing in IT when you don't need a full-fledged development team and hire separate specialists. Sometimes the project requires finding a couple of additional professionals, and you're free to hire outstaff workers to cover that scope of work.</p>\r\n<h3 class=\"align-center\"><span style=\"font-weight: bold; \">What are IT Outsourcing examples?</span></h3>\r\nThe individual or company that becomes your outsourcing partner can be located anywhere in the world — one block away from your office or on another continent.\r\nA Bay Area-based startup partnering with an app development team in Utah and a call center in the Philippines, or a UK-based digital marketing agency hiring a Magento developer from Ukraine are both examples of outsourcing.\r\n<h3 class=\"align-center\">Why You Should Use IT Outsourcing</h3>\r\nNow that you know what IT outsourcing is, its models, and types, it's time to clarify why you need to outsource and whether you really need it. Let's go over a few situations that suggest when to opt for IT outsourcing.\r\n<ul><li><span style=\"font-weight: bold;\">You are a domain expert with idea</span></li></ul>\r\nIf you're an industry expert with the idea that solves a real problem, IT outsourcing is your choice. In this case, your main goal is to enter the market and test the solution fast. An outsourced team will help you validate the idea, build an MVP to check the hypothesis, and implement changes in your product according to market needs. It saves you money, time and lets you reach the goal.\r\n<ul><li><span style=\"font-weight: bold;\">You have an early-stage startup</span></li></ul>\r\nIt's a common case that young startups spend money faster than they get a solid team and a ready-to-market product. The Failory found that financial problems are the 3rd reason why startup fails. So it makes more sense to reduce costs by hiring an outsourced team of professionals while your business lives on investor's money. You may employ a full-cycle product development studio covering all the blind spots and bringing your product to life.\r\n<ul><li><span style=\"font-weight: bold;\">You need a technical support</span></li></ul>\r\nEven if you already have a ready solution, but it demands some technical improvements – frameworks for backend components, new language, integrations with enterprise software, UX&amp;UI design – it makes more sense to find an experienced partner. There are many functions that IT outsourcing can cover, and again it saves you the time you'd otherwise spend on looking for qualified staff.<br /><br /><br />","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_IT_outsourcing.png","alias":"it-outsourcing"},"51":{"id":51,"title":"PaaS - Platform as a service","description":"<span style=\"font-weight: bold; \">Platform as a Service (PaaS)</span> or <span style=\"font-weight: bold; \">Application Platform as a Service (aPaaS)</span> or <span style=\"font-weight: bold; \">platform-based service</span> is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.\r\n<span style=\"font-weight: bold; \">PaaS can be delivered in three ways:</span>\r\n<span style=\"font-weight: bold;\">As a public cloud service</span> from a provider, where the consumer controls software deployment with minimal configuration options, and the provider provides the networks, servers, storage, operating system (OS), middleware (e.g. Java runtime, .NET runtime, integration, etc.), database and other services to host the consumer's application.\r\n<span style=\"font-weight: bold;\">As a private service</span> (software or appliance) behind a firewall.\r\n<span style=\"font-weight: bold;\">As software</span> deployed on a public infrastructure as a service.\r\n<span style=\"color: rgb(97, 97, 97); \">The original intent of PaaS technology was to simplify the code-writing process for developers, with the infrastructure and operations handled by the PaaS provider. Originally, all PaaSes were in the public cloud. Because many companies did not want to have everything in the public cloud, private and hybrid PaaS options (managed by internal IT departments) were created.</span>\r\n<span style=\"color: rgb(97, 97, 97); \">PaaS provides an environment for developers and companies to create, host and deploy applications, saving developers from the complexities of the infrastructure side (setting up, configuring and managing elements such as servers and databases).</span>\r\n<span style=\"color: rgb(97, 97, 97); \">PaaS products can improve the speed of developing an app, and allow the consumer to focus on the application itself. With PaaS, the consumer manages applications and data, while the provider (in public PaaS) or IT department (in private PaaS) manages runtime, middleware, operating system, virtualization, servers, storage and networking.</span>\r\n<span style=\"color: rgb(97, 97, 97); \">PaaS offerings may also include facilities for application design, application development, testing and deployment, as well as services such as team collaboration, web service integration, and marshalling, database integration, security, scalability, storage, persistence, state management, application versioning, application instrumentation, and developer community facilitation. Besides the service engineering aspects, PaaS solutions include mechanisms for service management, such as monitoring, workflow management, discovery and reservation.</span>\r\nThere are various types of PaaS providers. All offer application hosting and a deployment environment, along with various integrated services. Services offer varying levels of scalability and maintenance. Developers can write an application and upload it to a PaaS platform that supports their software language of choice, and the application runs on that PaaS.","materialsDescription":"<h1 class=\"align-center\">How PaaS works</h1>\r\n<p class=\"align-left\">PaaS does not replace a company's entire IT infrastructure for software development. It is provided through a cloud service provider's hosted infrastructure with users most frequently accessing the offerings through a web browser. PaaS can be delivered through public, private and hybrid clouds to deliver services such as application hosting and Java development.</p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold; \">Other PaaS services include:</span></p>\r\n<ul><li>Development team collaboration</li><li>Application design and development</li><li>Application testing and deployment</li><li>Web service integration</li><li>Information security</li><li>Database integration</li></ul>\r\n<p class=\"align-left\">Users pay for PaaS on a per-use basis. However, different platform as a service providers charge a flat monthly fee for access to the platform and its applications.</p>\r\n<h1 class=\"align-center\">What are the types of PaaS?</h1>\r\n<ul><li><span style=\"font-weight: bold; \">Public PaaS</span></li></ul>\r\nA public PaaS allows the user to control software deployment while the cloud provider manages the delivery of all other major IT components necessary to the hosting of applications, including operating systems, databases, servers and storage system networks. \r\nPublic PaaS vendors offer middleware that enables developers to set up, configure and control servers and databases without the necessity of setting up the infrastructure side of things. As a result, public PaaS and IaaS (infrastructure as a service) run together, with PaaS operating on top of a vendor's IaaS infrastructure while leveraging the public cloud. \r\n<ul><li><span style=\"font-weight: bold; \">Private PaaS</span></li></ul>\r\nA private PaaS is usually delivered as an appliance or software within the user's firewall which is frequently maintained in the company's on-premises data center. A private PaaS software can be developed on any type of infrastructure and can work within the company's specific private cloud. Private PaaS allows an organization to better serve developers, improve the use of internal resources and reduce the costly cloud sprawl that many companies face.\r\n<ul><li><span style=\"font-weight: bold; \">Hybrid PaaS </span></li></ul>\r\nCombines public PaaS and private PaaS to provide companies with the flexibility of infinite capacity provided by a public PaaS model and the cost efficiencies of owning an internal infrastructure in private PaaS. Hybrid PaaS utilizes a hybrid cloud.\r\n<ul><li><span style=\"font-weight: bold; \">Communication PaaS </span></li></ul>\r\nCPaaS is a cloud-based platform that allows developers to add real-time communications to their apps without the need for back-end infrastructure and interfaces. Normally, real-time communications occur in apps that are built specifically for these functions. Examples include Skype, FaceTime, WhatsApp and the traditional phone. CPaaS provides a complete development framework for the creation of real-time communications features without the necessity of a developer building their own framework.\r\n<ul><li><span style=\"font-weight: bold; \">Mobile PaaS</span> </li></ul>\r\nMPaaS is the use of a paid integrated development environment for the configuration of mobile apps. In an mPaaS, coding skills are not required. MPaaS is delivered through a web browser and typically supports public cloud, private cloud and on-premises storage.

The conventional mode of application testing is very time consuming, and cost associated with such kind of testing solution is also high. That is why demand for a solution to test application on the cloud and for the cloud is rising significantly as high quality, well-performing software across platforms drive business innovation and competitive positioning. Software vendors across the globe are investing a huge amount of money in research and development of software that can provide more software-centric IT infrastructure to their customer. These software vendors are looking for automated software testing (ASQ), software as a Service (SaaS) and adaptive infrastructure support in the cloud.\r\nCloud testing and ASQ software facilitates quick access to both superiority solution and support infrastructure to sustain complex software sourcing and dynamic development. Cloud testing solutions require fewer resources and less infrastructure investment than on-premise ASQ solutions.\r\nThe continuous development in cloud computing space is driving the growth of the global cloud testing and ASQ software market. Cloud computing is creating a new shift in IT model. Cloud computing facilitates organizations to adopt software as a Service at a very low cost. Software as a Service providers business organization a more agile framework and increase their efficiency, at the same time, software as a service is a complex phenomenon and requires continuous monitoring. As an organization is deploying more enterprise mobility solution and mobile application, cloud testing and ASQ software vendors are seeing a huge opportunity in the market.\r\nHowever, business organizations’ software needs are changing very frequently, and to cope with these rapidly changing software advancements is very difficult for cloud testing ASQ software vendors, and this is the biggest challenge cloud testing and ASQ software market is facing.","materialsDescription":" <span style=\"font-weight: bold; \">What is Cloud testing?</span>\r\nCloud testing is a form of software testing in which web applications use cloud computing environments (a &quot;cloud&quot;) to simulate real-world user traffic.\r\nCloud testing uses cloud infrastructure for software testing. Organizations pursuing testing in general and load, performance testing and production service monitoring, in particular, are challenged by several problems like limited test budget, meeting deadlines, high costs per test, a large number of test cases, and little or no reuse of tests and geographical distribution of users add to the challenges. Moreover, ensuring high-quality service delivery and avoiding outages requires testing in one's datacenter, outside the data-center, or both. Cloud Testing is the solution to all these problems. Effective unlimited storage, quick availability of the infrastructure with scalability, flexibility and availability of a distributed testing environment reduce the execution time of testing of large applications and lead to cost-effective solutions.\r\nTraditional approaches to test a software incurs a high cost to simulate user activity from different geographic locations. Testing firewalls and load balancers involve expenditure on hardware, software and its maintenance. In the case of applications where the rate of increase in a number of users is unpredictable or there is variation in deployment environment depending on client requirements, cloud testing is more effective.\r\n<span style=\"font-weight: bold; \">What are the types of testing?</span>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Stress</span></span>\r\nStress Test is used to determine the ability of the application to maintain a certain level of effectiveness beyond the breaking point. It is essential for any application to work even under excessive stress and maintain stability. Stress testing assures this by creating peak loads using simulators. But the cost of creating such scenarios is enormous. Instead of investing capital in building on-premises testing environments, cloud testing offers an affordable and scalable alternative.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Load</span></span>\r\nLoad testing of an application involves the creation of heavy user traffic and measuring its response. There is also a need to tune the performance of any application to meet certain standards. However, a number of tools are available for that purpose.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Performance</span></span>\r\nFinding out thresholds, bottlenecks &amp; limitations is a part of performance testing. For this, testing performance under a particular workload is necessary. By using cloud testing, it is easy to create such an environment and vary the nature of traffic on-demand. This effectively reduces cost and time by simulating thousands of geographically targeted users.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Functional</span></span>\r\nFunctional testing of both internet and non-internet applications can be performed using cloud testing. The process of verification against specifications or system requirements is carried out in the cloud instead of on-site software testing.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Compatibility</span></span>\r\nUsing a cloud environment, instances of different Operating Systems can be created on demand, making compatibility testing effortless.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Browser performance</span></span>\r\nTo verify the application's support for various browser types and performance in each type can be accomplished with ease. Various tools enable automated website testing from the cloud.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Latency</span></span>\r\nCloud testing is utilized to measure the latency between the action and the corresponding response for any application after deploying it on the cloud.\r\n<span style=\"font-weight: bold; \">What are the keys to successful testing?</span>\r\n<ol><li>Understanding a platform provider's elasticity model/dynamic configuration method</li><li>Staying abreast of the provider's evolving monitoring services and Service Level Agreements (SLAs)</li><li>Potentially engaging the service provider as an ongoing operations partner if producing commercial off-the-shelf (COTS) software</li><li>Being willing to be used as a case study by the cloud service provider. The latter may lead to cost reductions.</li></ol>\r\nCloud testing is often seen as only performance or load tests, however, as discussed earlier it covers many other types of testing. Cloud computing itself is often referred to as the marriage of software as a service (SaaS) and utility computing. In regard to test execution, the software offered as a service may be a transaction generator and the cloud provider's infrastructure software, or may just be the latter. Distributed Systems and Parallel Systems mainly use this approach for testing, because of their inherent complex nature. D-Cloud is an example of such a software testing environment.\r\nFor testing non-internet applications, virtual instances of testing environment can be quickly set up to do automated testing of the application. The cloud testing service providers provide an essential testing environment as per the requirement of the application under test. The actual testing of applications is performed by the testing team of the organization which owns the application or third-party testing vendors.\r\n<span style=\"font-weight: bold;\">What are the benefits?</span>\r\nThe ability and cost to simulate web traffic for software testing purposes have been an inhibitor to overall web reliability. The low cost and accessibility of the cloud's extremely large computing resources provide the ability to replicate real-world usage of these systems by geographically distributed users, executing wide varieties of user scenarios, at scales previously unattainable in traditional testing environments. Minimal start-up time along with quality assurance can be achieved by cloud testing.\r\nFollowing are some of the key benefits:\r\n<ul><li>Reduction in capital expenditure</li><li>Highly scalable</li></ul>\r\n<span style=\"font-weight: bold;\">What are the issues?</span>\r\nThe initial setup cost for migrating testing to a cloud is very high as it involves modifying some of the test cases to suit the cloud environment. This makes the decision of migration crucial. Therefore, cloud testing is not necessarily the best solution to all testing problems.\r\nLegacy systems &amp; services need to be modified in order to be tested on the cloud. Usage of robust interfaces with these legacy systems may solve this problem. Also like any other cloud services, cloud testing is vulnerable to security issues.\r\nThe test results may not be accurate due to the varying performance of the service providers’ network and the internet. In many cases, service virtualization can be applied to simulate the specific performance and behaviors required for accurate and thorough testing.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Cloud_Testing.png","alias":"cloud-testingasq-paas"},"395":{"id":395,"title":"Agile Application Life-Cycle Management Software","description":" Agile software development is an approach to software development under which requirements and solutions evolve through the collaborative effort of self-organizing and cross-functional teams and their customer(s)/end user(s). It advocates adaptive planning, evolutionary development, empirical knowledge, and continual improvement, and it encourages rapid and flexible response to change.\r\nThe term agile (sometimes written Agile) was popularized, in this context, by the Manifesto for Agile Software Development. The values and principles espoused in this manifesto were derived from and underpin a broad range of software development frameworks, including Scrum and Kanban.\r\nThere is significant anecdotal evidence that adopting agile practices and values improves the agility of software professionals, teams and organizations; however, some empirical studies have found no scientific evidence.\r\nAgile application lifecycle management (Agile ALM) is all the tools and processes that are used to manage software development projects based on flexible methodology. The traditional cascade design model uses a phase approach to the development life cycle. This approach means that no project phase starts earlier than the previous one ends. For example, the design does not begin before the collection of requirements ends. Development does not begin until the design is completed. Testing does not begin until development is fully completed. There are many tools to manage what is in the input and output of each phase.","materialsDescription":" Agile ALM brings together two seemingly contradictory development strategies. Agile promotes flexibility, rapid release cycles and quick response to change. Application lifecycle management (ALM) emphasizes tracking and documenting changes in an application -- from inception to retirement. Its processes are more controlled and less adaptive than the Agile methodology. That said, when put together, Agile and ALM act as complements, rending ALM more flexible and Agile more disciplined.\r\n<span style=\"font-weight: bold;\">What is Agile ALM?</span>\r\nDevelopment expert Yvette Francino described Agile ALM as ALM tools and processes that are used to manage Agile software development projects. For example, rather than using Waterfall's phased approach, Agile ALM offers an approach to software development in which design, code and requirements are all handled by the same team.\r\n<span style=\"font-weight: bold;\">How do you integrate Agile into an ALM framework?</span>\r\nAccording to Gerie Owen's article on Agile and ALM, adopting Agile means both a change to the ALM approach and a change to an organization's mind-set. An Agile ALM strategy will focus on the customer and will have the ability to adapt to shifting requirements -- from project planning to release management. For example, instead of just implementing controls to force early feedback from testers and business analysts, an organization would also foster a culture of collaboration.\r\n<span style=\"font-weight: bold;\">Are there tools that can help me achieve this?</span>\r\nALM tools are widely available but must be chosen with care, according to Yvette Francino, SearchSoftwareQuality contributor. Organizations should look for tools that facilitate the process without impeding acceptance of changing requirements. They would also need to integrate throughout the application lifecycle and be easy to maintain. In other words, the tool should manage the development process in an Agile way. In an article for SearchSoftwareQuality.com, Amy Reichert provides a list of Agile ALM tools and identifies their strengths and weaknesses. Rally Software, for example, offers a product that works well with Agile but, according to Reichert, does not provide an intuitive workflow. VersionOne, on the other hand, offers a tool that is more user-friendly but less compatible with Agile. Which one is best will depend on the company's needs.\r\n<span style=\"font-weight: bold;\">Are there challenges to Agile ALM that I should be aware of?</span>\r\nThe primary challenge to Agile ALM is in finding a balance between the two methodologies. A common pitfall is to over-ALM the development process. In other words, when developers and testers start to find workarounds to the software rules -- as they often do -- some react by creating more rules in order to more strictly enforce them. Meanwhile, processes lose their agility.\r\n<span style=\"font-weight: bold;\">How can I overcome these challenges?</span>\r\nTesting expert Amy Reichert cautions development teams to keep track of how many rules they add and how those rules are communicated. She also suggests having a discussion with the team, asking them why they are circumventing the process. Once everyone's role has been clarified, project managers can then decide which rules, if any, to add.\r\n<span style=\"font-weight: bold;\">Is Agile ALM a good approach for mobile development?</span>\r\nMobile development is faster and more competitive than traditional software development. It has newer technologies and higher-speed application cycles. These qualities could make mobile an excellent candidate for Agile ALM, but only if the methodology is amended to accommodate the challenges inherent in a more restrictive development process. In an article on mobile ALM, site editor James Denman suggested an ALM approach that focuses on smaller pieces of software and authenticates results as each part is finished. That way, teams can quickly discern whether the app will effectively serve its purpose or if it needs to be taken in a different direction.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Agile_Application_Life_Cycle_Management_Software.png","alias":"agile-application-life-cycle-management-software"},"397":{"id":397,"title":"Mobile Testing","description":" Mobile application testing is the process through which applications are tested for required quality, functionality, compatibility, usability, performance and other characteristics.\r\nIt includes a broad range of application testing and evaluation techniques that encompasses both standard software testing and mobile-platform-specific testing procedures.\r\nMobile application testing is typically performed by mobile application developers after a mobile application is developed or before it is released to consumers. Typically, the key objectives of mobile application testing are:\r\n<span style=\"font-style: italic;\">Hardware compatibility and functionality</span> - The mobile application’s response to a mobile device's physical input and interaction with components.

It is a continuous process throughout a project. A requirement is a capability to which a project outcome (product or service) should conform.\r\nThe purpose of requirements management is to ensure that an organization documents, verifies, and meets the needs and expectations of its customers and internal or external stakeholders. Requirements management begins with the analysis and elicitation of the objectives and constraints of the organization. Requirements management further includes supporting planning for requirements, integrating requirements and the organization for working with them (attributes for requirements), as well as relationships with other information delivering against requirements, and changes for these.\r\nThe traceability thus established is used in managing requirements to report back fulfilment of company and stakeholder interests in terms of compliance, completeness, coverage, and consistency. Traceabilities also support change management as part of requirements management in understanding the impacts of changes through requirements or other related elements (e.g., functional impacts through relations to functional architecture), and facilitating introducing these changes.\r\nRequirements management involves communication between the project team members and stakeholders, and adjustment to requirements changes throughout the course of the project. To prevent one class of requirements from overriding another, constant communication among members of the development team is critical. For example, in software development for internal applications, the business has such strong needs that it may ignore user requirements, or believe that in creating use cases, the user requirements are being taken care of.\r\nRequirements traceability is concerned with documenting the life of a requirement. It should be possible to trace back to the origin of each requirement and every change made to the requirement should therefore be documented in order to achieve traceability. Even the use of the requirement after the implemented features have been deployed and used should be traceable.\r\nRequirements come from different sources, like the business person ordering the product, the marketing manager and the actual user. These people all have different requirements for the product. Using requirements traceability, an implemented feature can be traced back to the person or group that wanted it during the requirements elicitation. This can, for example, be used during the development process to prioritize the requirement, determining how valuable the requirement is to a specific user. It can also be used after the deployment when user studies show that a feature is not used, to see why it was required in the first place.","materialsDescription":"<span style=\"font-weight: bold; \">Requirements activities</span>\r\nAt each stage in a development process, there are key requirements management activities and methods. To illustrate, consider a standard five-phase development process with Investigation, Feasibility, Design, Construction, and Test, and Release stages.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Investigation</span></span>\r\nIn Investigation, the first three classes of requirements are gathered from the users, from the business, and from the development team. In each area, similar questions are asked; what are the goals, what are the constraints, what are the current tools or processes in place, and so on. Only when these requirements are well understood can functional requirements be developed.\r\nIn the common case, requirements cannot be fully defined at the beginning of the project. Some requirements will change, either because they simply weren’t extracted, or because internal or external forces at work affect the project in mid-cycle.\r\nThe deliverable from the Investigation stage is a requirements document that has been approved by all members of the team. Later, in the thick of development, this document will be critical in preventing scope creep or unnecessary changes. As the system develops, each new feature opens a world of new possibilities, so the requirements specification anchors the team to the original vision and permits a controlled discussion of scope change.\r\nWhile many organizations still use only documents to manage requirements, others manage their requirements baselines using software tools. These tools allow requirements to be managed in a database, and usually have functions to automate traceability (e.g., by allowing electronic links to be created between parent and child requirements, or between test cases and requirements), electronic baseline creation, version control, and change management. Usually, such tools contain an export function that allows a specification document to be created by exporting the requirements data into a standard document application.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Feasibility</span></span>\r\nIn the Feasibility stage, the costs of the requirements are determined. For user requirements, the current cost of work is compared to the future projected costs once the new system is in place. Questions such as these are asked: “What are data entry errors costing us now?” Or “What is the cost of scrap due to operator error with the current interface?” Actually, the need for the new tool is often recognized as these questions come to the attention of financial people in the organization.\r\nBusiness costs would include, “What department has the budget for this?” “What is the expected rate of return on the new product in the marketplace?” “What’s the internal rate of return in reducing the costs of training and support if we make a new, easier-to-use system?”\r\nTechnical costs are related to software development costs and hardware costs. “Do we have the right people to create the tool?” “Do we need new equipment to support expanded software roles?” This last question is an important type. The team must inquire into whether the newest automated tools will add sufficient processing power to shift some of the burdens from the user to the system in order to save people time.\r\nThe question also points out a fundamental point about requirements management. A human and a tool form a system, and this realization is especially important if the tool is a computer or a new application on a computer. The human mind excels in parallel processing and interpretation of trends with insufficient data. The CPU excels in serial processing and accurate mathematical computation. The overarching goal of the requirements management effort for a software project would thus be to make sure the work being automated gets assigned to the proper processor. For instance, “Don’t make the human remember where she is in the interface. Make the interface report the human’s location in the system at all times.” Or “Don’t make the human enter the same data in two screens. Make the system store the data and fill in the second screen as needed.”\r\nThe deliverable from the Feasibility stage is the budget and schedule for the project.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Design</span></span>\r\nAssuming that costs are accurately determined and benefits to be gained are sufficiently large, the project can proceed to the Design stage. In Design, the main requirements management activity is comparing the results of the design against the requirements document to make sure that work is staying in scope.\r\nAgain, flexibility is paramount to success. Here’s a classic story of scope change in mid-stream that actually worked well. Ford auto designers in the early ‘80s were expecting gasoline prices to hit $3.18 per gallon by the end of the decade. Midway through the design of the Ford Taurus, prices had centered to around $1.50 a gallon. The design team decided they could build a larger, more comfortable, and more powerful car if the gas prices stayed low, so they redesigned the car. The Taurus launch set nationwide sales records when the new car came out, primarily because it was so roomy and comfortable to drive.\r\nIn most cases, however, departing from the original requirements to that degree does not work. So the requirements document becomes a critical tool that helps the team make decisions about design changes.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Construction and test</span></span>\r\nIn the construction and testing stage, the main activity of requirements management is to make sure that work and cost stay within schedule and budget, and that the emerging tool does, in fact, meet requirements. A main tool used in this stage is prototype construction and iterative testing. For a software application, the user interface can be created on paper and tested with potential users while the framework of the software is being built. The results of these tests are recorded in a user interface design guide and handed off to the design team when they are ready to develop the interface. This saves time and makes their jobs much easier.\r\nVerification: This effort verifies that the requirement has been implemented correctly. There are 4 methods of verification: analysis, inspection, testing, and demonstration. Numerical software execution results or through-put on a network test, for example, provides analytical evidence that the requirement has been met. Inspection of vendor documentation or spec sheets also verifies requirements. Actually testing or demonstrating the software in a lab environment also verifies the requirements: a test type of verification will occur when test equipment not normally part of the lab (or system under test) is used. Comprehensive test procedures which outline the steps and their expected results clearly identify what is to be seen as a result of performing the step. After the step or set of steps is completed the last step's expected result will call out what has been seen and then identify what requirements or requirements have been verified (identified by number). The requirement number, title, and verbiage are tied together in another location in the test document.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Requirements change management</span></span>\r\nHardly would any software development project be completed without some changes being asked of the project. The changes can stem from changes in the environment in which the finished product is envisaged to be used, business changes, regulation changes, errors in the original definition of requirements, limitations in technology, changes in the security environment and so on. The activities of requirements change management include receiving the change requests from the stakeholders, recording the received change requests, analyzing and determining the desirability and process of implementation, implementation of the change request, quality assurance for the implementation and closing the change request. Then the data of change requests be compiled, analyzed and appropriate metrics are derived and dovetailed into the organizational knowledge repository.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Release</span></span>\r\nRequirements management does not end with product release. From that point on, the data coming in about the application’s acceptability is gathered and fed into the Investigation phase of the next generation or release. Thus the process begins again.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Requirements_Visualization.png","alias":"requirements-visualization-definition-and-management"},"403":{"id":403,"title":"Software Quality Analysis and Measurement","description":" Software quality measures whether the software satisfies its requirements. Software requirements are classified as either functional or non-functional.\r\nFunctional requirements specify what the software should do. Functional requirements could be calculations, technical details, data manipulation, and processing, or any other specific function that defines what an application is meant to accomplish.\r\nNon-functional requirements specify how the system should work. Also known as “quality attributes” non-functional requirements include things like disaster recovery, portability, privacy, security, supportability, and usability.\r\nNote that most factors indicating software quality fit into the non-functional requirements category. And, while it’s obviously important that software does what it’s built to do, this is the bare minimum you would expect from any application.\r\nBelow are some examples of test metrics and methods for measuring the important aspects of software quality. Efficient measuring and testing of your software for quality is the only way to maximize the chances of releasing high-quality software in today’s fast-paced development environments.\r\nYou can measure reliability by counting the number of high priority bugs found in production. You can also use load testing, which assesses how well the software functions under ordinary conditions of use. It’s important to note that “ordinary conditions of use” can vary between low loads and high loads—the point is that such environments are expected.\r\nLoad testing is also useful for measuring performance efficiency. Stress testing is an important variation on load testing used to determine the maximum operating capacity of an application.\r\nStress testing is conducted by inundating software with requests far exceeding its normal and expected patterns of use to determine how far a system can be pushed before it breaks. With stress testing, you get insight into the recoverability of the software when it breaks—ideally, a system that fails should have a smooth recovery.\r\nYou can measure security by assessing how long it takes to patch or fix software vulnerabilities. You can also check actual security incidents from previous software versions, including whether the system was breached and if any breaches caused downtime for users. All previous security issues should, of course, be addressed in future releases.\r\nCounting the number of lines of code is a simple measure of maintainability—software with more lines of code is harder to maintain, meaning changes are more likely to lead to errors.\r\nThere are several detailed test metrics used to check the complexity of code, such as cyclomatic complexity, which counts the amount of linearly independent paths through a program’s source code.\r\nYou can check the rate of delivery by counting the number of software releases. Another measure is the number of “stories” or user requirements shipped to the user.\r\nYou can test the GUI to make sure it’s simple and not frustrating for end-users. The problem is that GUI testing is complex and time-consuming – there are many possible GUI operations and sequences that require testing in most software. And that means it takes a long time to design test cases.\r\nThe complexity of GUI testing competes with the objective of releasing software quickly, which has necessitated the implementation of automated testing. Several test suites that completely simulate user behavior are available.","materialsDescription":" <span style=\"font-weight: bold;\">What is Software Quality Metrics?</span>\r\nThe word 'metrics' refers to standards for measurements. Software Quality Metrics means a measurement of attributes, pertaining to software quality along with its process of development.\r\nThe term &quot;software quality metrics&quot; illustrate the picture of measuring the software qualities by recording the number of defects or security loopholes present in the software.

It encompasses several different aspects, including webpage layout, content production, and graphic design. While the terms web design and web development are often used interchangeably, web design is technically a subset of the broader category of web development.\r\nWebsites are created using a markup language called HTML. Web designers build webpages using HTML tags that define the content and metadata of each page. The layout and appearance of the elements within a webpage are typically defined using CSS, or cascading style sheets. Therefore, most websites include a combination of HTML and CSS that defines how each page will appear in a browser.\r\nSome web designers prefer to hand code pages (typing HTML and CSS from scratch), while others use a &quot;WYSIWYG&quot; editor like Adobe Dreamweaver. This type of editor provides a visual interface for designing the webpage layout and the software automatically generates the corresponding HTML and CSS code. Another popular way to design websites is with a content management system like WordPress or Joomla. These services provide different website templates that can be used as a starting point for a new website. Webmasters can then add content and customize the layout using a web-based interface.\r\nWhile HTML and CSS are used to design the look and feel of a website, images must be created separately. Therefore, graphic design may overlap with web design, since graphic designers often create images for use on the Web. Some graphics programs like Adobe Photoshop even include a &quot;Save for Web…&quot; option that provides an easy way to export images in a format optimized for web publishing.","materialsDescription":" <span style=\"font-weight: bold;\">Why is Web Design Important?</span>\r\nIt can be difficult to understand why most businesses are willing to pay top dollar for web design work. After all, having a functional website matters more than how it looks, right? Unfortunately, this isn’t the case. Today, the most important aspect of an online business presence in web design.\r\nThis means that businesses should always try to find the best web styles that work for their businesses. Although there are several people who can create websites, it takes a skilled person to design a website that looks polished and functional. Here are some more reasons why web design is important to good business.\r\n<span style=\"font-weight: bold;\">A Good Site Increases Customer Conversion</span>\r\nWhen a business has a well-designed website, it becomes easier to get more customer conversions. This is because a well-designed website uses its elements to lead customers directly to what they need without distractions.\r\n<span style=\"font-weight: bold;\">A Responsive Website Helps Business Reach More Clients</span>\r\nAccording to recent research by Pew Research Center, it was discovered that more and more users are using their mobile phones to do business. This means that businesses need to take advantage of this new set of customers by creating websites that can get clients who are away from their computers.\r\n<span style=\"font-weight: bold;\">Websites Help in Business Branding</span>\r\nA poor looking website will damage the brand of any company while a scummy-looking website drives customers away.

Google states that &quot;Android apps can be written using Kotlin, Java, and C++ languages&quot; using the Android software development kit (SDK), while using other languages is also possible. All non-JVM languages, such as Go, JavaScript, C, C++ or assembly, need the help of JVM language code, that may be supplied by tools, likely with restricted API support. Some languages/programming tools allow cross-platform app support, i.e. for both Android and iOS. Third party tools, development environments and language support have also continued to evolve and expand since the initial SDK was released in 2008. In addition, with major business entities like Walmart, Amazon, Bank of America etc. eyeing to engage and sell through mobiles, mobile application development is witnessing a transformation.\r\nAndroid was created by the Open Handset Alliance, which is led by Google. The early feedback on developing applications for the Android platform was mixed. Issues cited include bugs, lack of documentation, inadequate QA infrastructure, and no public issue-tracking system. In December 2007, MergeLab mobile startup founder Adam MacBeth stated, &quot;Functionality is not there, is poorly documented or just doesn't work... It's clearly not ready for prime time.&quot; Despite this, Android-targeted applications began to appear the week after the platform was announced. The first publicly available application was the Snake game.\r\nA preview release of the Android SDK was released on November 12, 2007. On July 15, 2008, the Android Developer Challenge Team accidentally sent an email to all entrants in the Android Developer Challenge announcing that a new release of the SDK was available in a &quot;private&quot; download area. The email was intended for winners of the first round of the Android Developer Challenge. The revelation that Google was supplying new SDK releases to some developers and not others (and keeping this arrangement private) led to widely reported frustration within the Android developer community at the time.\r\nOn August 18, 2008, the Android 0.9 SDK beta was released. This release provided an updated and extended API, improved development tools and an updated design for the home screen. Detailed instructions for upgrading are available to those already working with an earlier release. On September 23, 2008, the Android 1.0 SDK (Release 1) was released. According to the release notes, it included &quot;mainly bug fixes, although some smaller features were added.&quot; It also included several API changes from the 0.9 version. Multiple versions have been released since it was developed.\r\nOn December 5, 2008, Google announced the first Android Dev Phone, a SIM-unlocked and hardware-unlocked device that is designed for advanced developers. It was a modified version of HTC's Dream phone. While developers can use regular consumer devices to test and use their applications, some developers may choose a dedicated unlocked or no-contract device.\r\nAs of July 2013, more than one million applications have been developed for Android, with over 25 billion downloads. A June 2011 research indicated that over 67% of mobile developers used the platform, at the time of publication. Android smartphone shipments are forecast to exceed 1.2 billion units in 2018 with an 85% market share.","materialsDescription":" <span style=\"font-weight: bold;\">Where does Android come from?</span>\r\nIt comes from Google, who actually acquired Android in 2005 (no, Google didn't invent it). The search giant performs regular updates along with an annual major update.\r\nThe operating system is based on the Linux kernel – if you have friends who work in IT, you may have heard of it. This is the GNU / Linux operating system based structure, which is a unix type system (portable operating system, multitasking and multi-user). The Linux kernel is one of the most prominent examples of free software.\r\n<span style=\"font-weight: bold;\">Why does Android look different on each phone?</span>\r\nAndroid doesn't look different on every device, but it does have a number of different versions. Android is open-source, which means that manufacturers are free to customize the software and make it their own.\r\nThe 'purest' version of Android is often referred to as 'stock Android' and it's often preferred by the Android community: it's the original software as Google intended.\r\nOther user interfaces (UI) include Samsung's TouchWiz, Sony's Xperia, and Huawei's Emotion. See what they all look like in our Android UI comparison.\r\n<span style=\"font-weight: bold;\">What are the advantages of Android?</span>\r\nChoice. For example, if you want iOS, you have a choice of iPhone, iPhone or iPhone. If you go for Android there are stacks of great devices to choose from, from cheap and cheerful handsets to really impressive flagships. Those flagships are often cheaper than the equivalent Apple devices, too.\r\nAndroid’s choice isn’t just about hardware. It’s about everything else too. Android is incredibly easy to customize, both in terms of how it looks and how it works, and the various app stores aren’t as tightly controlled as its rivals’ stores, like Apple.\r\n<span style=\"font-weight: bold;\">What’s with the candy names?</span>\r\nEach new version of Android gets a code name based on consecutive letters of the alphabet. The most recent version is known as Marshmallow because it is the Android M release. Previous versions have included Lollipop, KitKat, Jelly Bean and Gingerbread.\r\n<span style=\"font-weight: bold;\">What’s the best thing about Android?</span>\r\nOptions, many options. With Android, you have hundreds of gadgets at your disposal, the cheapest, the most expensive and innovative market. Android is also incredibly customizable, both in their roles, as in his appearance. You can really make a unique mobile experience for yourself with this OS.\r\n<span style=\"font-weight: bold;\">What’s the worst thing about Android?</span>\r\nGetting updates. In many cases, manufacturers don’t seem to care about providing software updates for devices they’ve already sold you. Even when they do provide updates they take their sweet time about it. That’s why some consider rooting: you can download the updates yourself and apply them instead of waiting for the manufacturer to get around to it.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Android_Software_Application.png","alias":"android-software-application"},"598":{"id":598,"title":"Mobile Website Development","description":" Today, virtually no company can effectively conduct its business without having its own website.

It is intended to let application developers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but it has fewer low-level facilities than either of them. As of 2019, Java was one of the most popular programming languages in use according to GitHub, particularly for client-server web applications, with a reported 9 million developers.\r\nJava was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle) and released in 1995 as a core component of Sun Microsystems' Java platform. The original and reference implementation Java compilers, virtual machines, and class libraries were originally released by Sun under proprietary licenses. As of May 2007, in compliance with the specifications of the Java Community Process, Sun had relicensed most of its Java technologies under the GNU General Public License. Meanwhile, others have developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java (bytecode compiler), GNU Classpath (standard libraries), and IcedTea-Web (browser plugin for applets).\r\nThe latest versions are Java 13, released in September 2019, and Java 11, a currently supported long-term support (LTS) version, released on September 25, 2018; Oracle released for the legacy Java 8 LTS the last free public update in January 2019 for commercial use, while it will otherwise still support Java 8 with public updates for personal use up to at least December 2020. Oracle (and others) highly recommend uninstalling older versions of Java because of serious risks due to unresolved security issues. Since Java 9 (and 10 and 12) is no longer supported, Oracle advises its users to immediately transition to the latest version (currently Java 13) or an LTS release.","materialsDescription":"<span style=\"font-weight: bold; \">What is Java technology and what is its application?</span>\r\nJava is a programming language and computing platform that was first launched by Sun Microsystems in 1995.

In addition, the Java virtual machine was optimized - since 2000, the HotSpot virtual machine has been used for this. As of February 2012, Java 7 code is approximately 1.8 times slower than C code.\r\nSome platforms offer hardware runtime support for Java.

Developed in 1998–2001 by a group of engineers under the leadership of Anders Hejlsberg at Microsoft as the main language for developing applications for the Microsoft .NET platform. The compiler with C# is included in the standard installation of the .NET itself, so programs on it can be created and compiled even without tools like Visual Studio.\r\nC# refers to a family of languages ​​with a C-like syntax, of which its syntax is closest to C++ and Java. The language has strict static typing, supports polymorphism, operator overloading, pointers to member functions of classes, attributes, events, properties, exceptions, comments in XML format. Having taken a lot from their predecessors - C++, Java, Delphi, Modula and Smalltalk - C#, based on the practice of using them, excludes some models that have proven to be problematic when developing software systems: thus, C # does not support multiple class inheritance (unlike C ++).\r\nC# was developed as an application level programming language for the CLR and, as such, depends primarily on the capabilities of the CLR itself. This concerns, first of all, the C # type system, which reflects FCL. The presence or absence of certain expressive features of the language is dictated by whether a particular language feature can be translated into the corresponding CLR constructs. So, with the development of the CLR from version 1.1 to 2.0, C # itself was significantly enriched; similar interaction should be expected in the future. (However, this pattern was broken with the release of C # 3.0, which are language extensions that do not rely on .NET platform extensions.) The CLR provides C #, like all other .NET-oriented languages, many of the features that the “classical” programming languages ​​lack. For example, garbage collection is not implemented in C # itself, but the CLR is done for programs written in C # just like it is done for programs on VB.NET, J #, and others.","materialsDescription":"<span style=\"font-weight: bold;\"> Why is it necessary to study the C# programming language?</span>\r\n<span style=\"font-weight: bold;\">Reason # 1.

IoT (Internet of Things) is a concept of a comprehensive Internet, Internet connection of refrigerators, air conditioners, cars and even sneakers with the aim of providing its owner with greater comfort, and on the other hand increasing their retailers' profits, calculating the amount of what, how much and when availability in warehouses, obtaining certain information about a person and his habits, about the environment.</li><li>Science and its application, for example, conducting complex experimental calculations, cryptography, pattern recognition, and the like.</li></ul>\r\n<span style=\"font-weight: bold;\">Reason # 5. C# is strongly typed, so it is easier for them to master beginners</span>\r\nAs for the comparison of programming languages, it should be noted that the C# programming language is multi-level. This means that it is somewhat similar to English. The C# programming language has strong static typing, supports polymorphism, operator overloading, pointers to member functions of classes, attributes, events, properties, exceptions, comments in XML format. Having adopted a lot from their predecessors - C++, Delphi, Modula, Smalltalk - in C #, relying on the practice of using them, deliberately excluded some models that proved to be problematic when developing software systems in the above-mentioned programming languages.\r\nThe syntax is quite minimalistic - with manual memory management. This is inconvenient for many, but tracking the correctness of functions, understanding the transmission of arguments is closely related to the study of the C# programming language.\r\nSince the syntax of C# is close to C, C++ and Java, then, fluent in C #, you can later learn them in one breath.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_C_Development.png","alias":"c-development"},"649":{"id":649,"title":"QA - Quality assurance","description":" <span style=\"font-weight: bold; \">Quality Assurance (QA)</span> is defined as an activity to ensure that an organization is providing the best possible product or service to customers. QA focuses on improving the processes to deliver Quality Products to the customer. An organization has to ensure, that processes are efficient and effective as per the quality standards defined for software products. Quality Assurance is popularly known as <span style=\"font-weight: bold; \">QA Testing. </span>\r\nQA establishes and maintains set requirements for developing or manufacturing reliable products. A quality assurance system is meant to increase customer confidence and a company's credibility, while also improving work processes and efficiency, and it enables a company to better compete with others.\r\nQuality assurance helps a company create products and services that meet the needs, expectations and requirements of customers. It yields high-quality product offerings that build trust and loyalty with customers. The standards and procedures defined by a quality assurance program help prevent product defects before they arise.\r\n<span style=\"font-weight: bold; \">Quality assurance utilizes one of three methods:</span>\r\n<span style=\"font-weight: bold; \">Failure testing, </span>which continually tests a product to determine if it breaks or fails. For physical products that need to withstand stress, this could involve testing the product under heat, pressure or vibration. For software products, failure testing might involve placing the software under high usage or load conditions.\r\n<span style=\"font-weight: bold; \">Statistical process control (SPC),</span> a methodology based on objective data and analysis and developed by Walter Shewhart at Western Electric Company and Bell Telephone Laboratories in the 1920's and 1930's. This methodology uses statistical methods to manage and control the production of products.\r\n<span style=\"font-weight: bold; \">Total quality management (TQM),</span> which applies quantitative methods as the basis for continuous improvement. TQM relies on facts, data and analysis to support product planning and performance reviews.\r\n<span style=\"font-weight: bold; \">Quality assurance in software.</span> Software quality assurance&nbsp; management (SQA) systematically finds patterns and the actions needed to improve development cycles. Finding and fixing coding errors can carry unintended consequences; it is possible to fix one thing, yet break other features and functionality at the same time.\r\nSQA software has become important for developers as a means of avoiding errors before they occur, saving development time and expenses. Even with SQA processes in place, an update to software can break other features and cause defects - commonly known as bugs.\r\n\r\n","materialsDescription":"<h1 class=\"align-center\"> Differences between Software testing and SQA services</h1>\r\n<ul><li><span style=\"font-weight: bold; \">SQA tools</span></li></ul>\r\n- Is about engineering process that ensures quality\r\n- Involve activities related to the implementation of processes, procedures, and standards.\r\n- Process focused \r\n- Preventive technique\r\n- Proactive measure\r\n- The scope of software quality testing tools applied to all products that will be created by the organization\r\n<ul><li><span style=\"font-weight: bold; \">Software Testing</span></li></ul>\r\n- Software Testing is to test a product for problems before the product goes live\r\n- Involves actives concerning verification of product Example - Review Testing\r\n- Product focused\r\n - Corrective technique\r\n- Reactive measure\r\n- The scope of Software Testing applies to a particular product being tested\r\n<h1 class=\"align-center\">Manual QA testing services Vs Automated Quality Assurance Testing</h1>\r\nSoftware testing is a huge domain, but it can be broadly categorized into two areas: manual testing and automated testing. Both of them can be used to achieve the best results, but it is always worth knowing the difference between the two. Each testing type – manual and automated – comes with its own set of advantages and disadvantages. \r\nYou can choose between manual and quality assurance testing services based on a variety of factors.

Functional testing can be manual or automatic. Functional testing software usually provides some input so that you can evaluate the output to see how the software works.\r\nFunctional testing is one of the types of testing aimed at checking the compliance of the functional requirements of the software with its actual characteristics. The main objective of functional testing is to confirm that the developed software product has all the functionality required by the customer.\r\nDepending on the purpose, functional testing may be conducted:\r\nBased on the functional requirements specified in the requirements specification. At the same time, test cases are created for testing (test cases), the compilation of which takes into account the priority of software functions that must be covered by tests. Thus, we can make sure that all the functions of the developed product work correctly with different types of input data, their combinations, quantities, etc.\r\nBased on the business processes that the application must provide. In this case, we are not interested in the performance of individual software functions, as we are the correctness of the operations performed, in terms of system usage scenarios. Thus, testing in this case will be based on options for using the system (use cases).\r\nThe aspects described above are implemented using the following types and levels of testing:\r\n<ul><li>Modular (component).</li><li>Integration.</li><li>Systemic.</li><li>Regression.</li><li>Acceptance.</li></ul>\r\nAss well, there are many other types that provide complete and comprehensive testing of functional requirements for software.\r\nChoosing the right functional testing tool for projects is key.

The security mechanisms of the system are tested, under operational conditions, for correct operation.\r\nFunctional testing verifies that the end user gets what they want from the application. It involves testing to ensure that the tasks or the steps required for complete functionality work well. Functional testing involves testing of functional requirements as per the specification.\r\n<span style=\"font-weight: bold;\">What are the differences between system and functional testing?</span>\r\nSystem testing has classifications like functional and non-functional testing. Hence the functional testing is a part of system testing.\r\nSystem testing allows the testers to test the typical end product. Every single module, interface and every minute detail are needed to be tested in system testing.\r\nFunctional testing is aimed at testing the functionalities of the product being tested. These functionalities include volume, stress, load, security, scalability, performance, etc. Hardware and software are not concerned with functional testing.\r\nFunctional testing involves testing of functional requirements as per the specification. On the other hand, system testing involves testing the system as a whole. This may involve testing of proper installation and uninstalling of the application. System testing tests for all internal and external components that make the system.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_functional_testing_tools.png","alias":"functional-testing-tools"},"808":{"id":808,"title":"Bug tracking systems","description":" A bug tracking system or defect tracking system is a software application that keeps track of reported software bugs in software development projects. It may be regarded as a type of issue tracking system.\r\nMany bug tracking systems, such as those used by most open-source software projects, allow end-users to enter bug reports directly. Other systems are used only internally in a company or organization doing software development. Typically bug tracking systems are integrated with other project management software.\r\nA bug tracking system is usually a necessary component of a good software development infrastructure, and consistent use of a bug or issue tracking system is considered one of the &quot;hallmarks of a good software team&quot;.\r\nA major component of a bug tracking system is a database that records facts about known bugs. Facts may include the time a bug was reported, its severity, the erroneous program behavior, and details on how to reproduce the bug; as well as the identity of the person who reported it and any programmers who may be working on fixing it.\r\nTypical bug tracking systems support the concept of the life cycle for a bug which is tracked through the status assigned to the bug. A bug tracking system should allow administrators to configure permissions based on status, move the bug to another status, or delete the bug. The system should also allow administrators to configure the bug statuses and to what extent a bug in a particular status can be moved. Some systems will e-mail interested parties, such as the submitter and assigned programmers, when new records are added or the status changes.\r\nThe main benefit of a bug-tracking system is to provide a clear centralized overview of development requests (including both bugs and improvements, the boundary is often fuzzy), and their state. The prioritized list of pending items (often called backlog) provides valuable input when defining the product road map, or maybe just &quot;the next release&quot;.\r\nIn a corporate environment, a bug-tracking system may be used to generate reports on the productivity of programmers at fixing bugs. However, this may sometimes yield inaccurate results because different bugs may have different levels of severity and complexity. The severity of a bug may not be directly related to the complexity of fixing the bug. There may be different opinions among the managers and architects.\r\nA local bug tracker (LBT) is usually a computer program used by a team of application support professionals (often a help desk) to keep track of issues communicated to software developers. Using an LBT allows support professionals to track bugs in their &quot;own language&quot; and not the &quot;language of the developers.&quot; In addition, an LBT allows a team of support professionals to track specific information about users who have called to complain — this information may not always be needed in the actual development queue. Thus, there are two tracking systems when an LBT is in place.","materialsDescription":" <span style=\"font-weight: bold;\">What does Bug Tracking mean?</span>\r\nBug tracking is a process used by quality assurance personnel and programmers to keep track of software problems and resolutions. A bug tracking system is normally put in place to store information about reported bugs. This type of issue-tracking system provides a clear, centralized overview of development requests and their corresponding states.\r\nBug tracking enables users to enter bug reports directly into a system that logs and tracks them. Diligent use of a bug tracking system provides a record of a software team's effectiveness. Local bug trackers are often used by teams of application support professionals to keep track of issues communicated to software developers.\r\nBug tracking systems include a database, which keeps track of facts pertaining to each bug. These facts might include the time a bug was reported, its severity, incorrect program behavior, details on how to recreate the bug,who reported the bug and what the programmers did to fix it. Bug tracking systems are associated with a bug's life cycle, which is tracked through the status assigned to each bug. This allows administrators to set permissions based on a bug's status, move bugs to other statuses or delete them.<br /><br />","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon-bug-tracking-systems.png","alias":"bug-tracking-systems"}},"companyUrl":"https://logicalstreet.com/","countryCodes":["IND"],"certifications":[],"isSeller":true,"isSupplier":true,"isVendor":true,"presenterCodeLng":"","seo":{"title":"LogicalStreet Technology Pvt.
