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"},"591":{"id":591,"title":"Software Development","description":" Software development is the process of conceiving, specifying, designing, programming, documenting, testing, and bug fixing involved in creating and maintaining applications, frameworks, or other software components. Software development is a process of writing and maintaining the source code, but in a broader sense, it includes all that is involved between the conception of the desired software through to the final manifestation of the software, sometimes in a planned and structured process. Therefore, software development may include research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products.\r\nSoftware can be developed for a variety of purposes, the three most common being to meet specific needs of a specific client/business (the case with custom software), to meet a perceived need of some set of potential users (the case with commercial and open-source software), or for personal use (e.g. a scientist may write software to automate a mundane task). Embedded software development, that is, the development of embedded software, such as used for controlling consumer products, requires the development process to be integrated with the development of the controlled physical product. System software underlies applications and the programming process itself and is often developed separately.\r\nThe need for better quality control of the software development process has given rise to the discipline of software engineering, which aims to apply the systematic approach exemplified in the engineering paradigm to the process of software development.\r\nThere are many approaches to software project management, known as software development life cycle models, methodologies, processes, or models. The waterfall model is a traditional version, contrasted with the more recent innovation of agile software development.","materialsDescription":" <span style=\"font-weight: bold; \">What is software development?</span>\r\nSoftware itself is the set of instructions or programs that tell a computer what to do. It is independent of hardware and makes computers programmable. There are three basic types:\r\n<span style=\"font-weight: bold; \">System software</span> to provide core functions such as operating systems, disk management, utilities, hardware management, and other operational necessities.\r\n<span style=\"font-weight: bold; \">Programming software</span> to give programmers tools such as text editors, compilers, linkers, debuggers and other tools to create code.\r\n<span style=\"font-weight: bold; \">Application software</span> (applications or apps) to help users perform tasks. Office productivity suites, data management software, media players and security programs are examples. Applications also refer to web and mobile applications like those used to shop on Amazon.com, socialize with Facebook or post pictures to Instagram.\r\nA possible fourth type is <span style=\"font-weight: bold; \">embedded software.</span> Embedded systems software is used to control machines and devices not typically considered computers — telecommunications networks, cars, industrial robots and more. These devices, and their software, can be connected as part of the Internet of Things (IoT).\r\nSoftware development is primarily conducted by programmers, software engineers, and software developers. These roles interact and overlap, and the dynamics between them vary greatly across development departments and communities.\r\n<span style=\"font-weight: bold; \">Programmers, or coders,</span> write source code to program computers for specific tasks like merging databases, processing online orders, routing communications, conducting searches or displaying text and graphics. Programmers typically interpret instructions from software developers and engineers and use programming languages like C++ or Java to carry them out.\r\n<span style=\"font-weight: bold; \">Software engineers</span> apply engineering principles to build software and systems to solve problems. They use modeling language and other tools to devise solutions that can often be applied to problems in a general way, as opposed to merely solving for a specific instance or client. Software engineering solutions adhere to the scientific method and must work in the real world, as with bridges or elevators.\r\n<span style=\"font-weight: bold; \">Software developers</span> have a less formal role than engineers and can be closely involved with specific project areas — including writing code. At the same time, they drive the overall software development lifecycle — including working across functional teams to transform requirements into features, managing development teams and processes, and conducting software testing and maintenance.\r\nThe work of software development isn’t confined to coders or development teams. Professionals such as scientists, device fabricators, and hardware makers also create software code even though they are not primarily software developers. Nor is it confined to traditional information technology industries such as software or semiconductor businesses. In fact, according to the Brookings Institute, those businesses “account for less than half of the companies performing software development.”\r\nAn important distinction is custom software development as opposed to commercial software development. Custom software development is the process of designing, creating, deploying and maintaining software for a specific set of users, functions or organizations. In contrast, commercial off-the-shelf software (COTS) is designed for a broad set of requirements, allowing it to be packaged and commercially marketed and distributed.\r\n<span style=\"font-weight: bold;\">Steps in the software development process</span>\r\nDeveloping software typically involves the following steps:\r\n<ul><li><span style=\"font-weight: bold;\">Selecting a methodology</span> to establish a framework in which the steps of software development are applied. It describes an overall work process or roadmap for the project. Methodologies can include Agile development, DevOps, Rapid Application Development (RAD), Scaled Agile Framework (SAFe), Waterfall and others.</li><li><span style=\"font-weight: bold;\">Gathering requirements</span> to understand and document what is required by users and other stakeholders.</li><li><span style=\"font-weight: bold;\">Choosing or building architecture</span> as the underlying structure within which the software will operate.</li><li><span style=\"font-weight: bold;\">Developing a design</span> around solutions to the problems presented by requirements, often involving process models and storyboards.</li><li><span style=\"font-weight: bold;\">Constructing code</span> in the appropriate programming language. Involves peer and team review to eliminate problems early and produce quality software faster.</li><li><span style=\"font-weight: bold;\">Testing</span> with pre-planned scenarios as part of software design and coding — and conducting performance testing to simulate load testing on the application.</li><li><span style=\"font-weight: bold;\">Managing configuration and defects</span> to understand all the software artifacts (requirements, design, code, test) and build distinct versions of the software. Establish quality assurance priorities and release criteria to address and track defects.</li><li><span style=\"font-weight: bold;\">Deploying</span> the software for use and responding to and resolving user problems.</li><li><span style=\"font-weight: bold;\">Migrating data</span> to the new or updated software from existing applications or data sources if necessary.</li><li><span style=\"font-weight: bold;\">Managing and measuring the project</span> to maintain quality and delivery over the application lifecycle, and to evaluate the development process with models such as the Capability Maturity Model (CMM).</li></ul>\r\nThe steps of the software development process fit into application lifecycle management.\r\n<ul><li>Requirements analysis and specification</li><li>Design and development</li><li>Testing</li><li>Deployment</li><li>Maintenance and support</li></ul>\r\nSoftware development process steps can be grouped into the phases of the lifecycle, but the importance of the lifecycle is that it recycles to enable continuous improvement.

It can improve customer experiences, bring more innovative, feature-rich products to market faster, and make operations more efficient, safe and productive.\r\nSoftware development is also important because it is pervasive.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Software_Development.png","alias":"software-development"},"601":{"id":601,"title":"Custom Software Development","description":" Custom software (also known as bespoke software or tailor-made software) is software that organization for some specific organization or another user. As such, it can be contrasted with the use of software packages developed for the mass market, such as commercial off-the-shelf (COTS) software, or existing free software.\r\nSince custom software is developed for a single customer it can accommodate that customer's particular preferences and expectations. Custom software may be developed in an iterative process, allowing all nuances and possible hidden risks to be taken into account, including issues which were not mentioned in the original requirement specifications (which are, as a rule, never perfect). In particular, the first phase in the software development process may involve many departments, materchode including marketing, engineering, research and development and general management.\r\nLarge companies commonly use custom software for critical functions, including content management, inventory management, customer management, human resource management, or otherwise to fill the gaps present in the existing software packages. Often such software is legacy software, developed before COTS or free software packages offering the required functionality became available.\r\nCustom software development is often considered expensive compared to off-the-shelf solutions or products. This can be true if one is speaking of typical challenges and typical solutions. However, it is not always true. In many cases, COTS software requires customization to correctly support the buyer's operations. The cost and delay of COTS customization can even add up to the expense of developing custom software. Cost is not the only consideration, however, as the decision to opt for custom software often includes the requirement for the purchaser to own the source code, to secure the possibility of future development or modifications to the installed system.\r\nAdditionally, COTS comes with upfront license costs which vary enormously but sometimes run into the millions (in terms of dollars). Furthermore, the big software houses that release COTS products revamp their product very frequently. Thus a particular customization may need to be upgraded for compatibility every two to four years. Given the cost of customization, such upgrades also turn out to be expensive, as a dedicated product release cycle will have to be earmarked for them.\r\nThe decision to build custom software or go for a COTS implementation would usually rest on one or more of the following factors:\r\n<ul><li>Finances - both cost and benefit: The upfront license cost for COTS products mean that a thorough cost-benefit analysis of the business case needs to be done. However it is widely known that large custom software projects cannot fix all three of scope, time/cost and quality constant, so either the cost or the benefits of a custom software project will be subject to some degree of uncertainty - even disregarding the uncertainty around the business benefits of a feature that is successfully implemented.</li><li>Supplier - In the case of COTS, is the supplier likely to remain in business long, and will there be adequate support and customization available? Alternatively, will there be a realistic possibility of getting support and customization from third parties? In the case of custom software, software development may be outsourced or done in-house. If it is outsourced, the question is: is the supplier reputable, and do they have a good track record?</li><li>Time to market: COTS products usually have a quicker time to market</li><li>Size of implementation: COTS comes with standardization of business processes and reporting. For a global or national organization, these can bring in gains in cost savings, efficiency and productivity, if the branch offices are all willing and able to use the same COTS without heavy customizations (which is not always a given).</li></ul>","materialsDescription":" <span style=\"font-weight: bold;\">Why is custom software such a large investment?</span>\r\nBuilding a custom web application is a time-consuming endeavor. It takes time to learn the processes of your business, to gather requirements, to flesh out your needs, and to build the software. Put simply, time is money.\r\nWhile it’s a large investment, by investing in custom software, you’ll own the code instead of having a long-term licensing agreement with another software company.\r\n<span style=\"font-weight: bold;\">How could my business benefit from custom software?</span>\r\nA custom business software solution increases process efficiency through process automation. When business processes are properly automated, they minimize the waste in time and resources that the original processes contained.\r\nThink of it this way: with software that already exists, you have to modify your process to meet software capabilities. With custom software, you can build a system around the existing processes you have in place. You took a lot of time to develop those processes, so why should you revamp your business?\r\n<span style=\"font-weight: bold;\">What is IP and how important is it that I own it?</span>\r\nIP stands for Intellectual Property. When you deal with anything creative, you have to think about copyright and the intellectual property on that work and that includes the creation of software code.\r\nThis gets back to the question of buying vs. building. If there is an existing solution that can suit your needs just fine, then it makes sense to buy, but the software developer owns the code and you are basically licensing the software from there. However, if you need a specialized solution that is customized to your needs and decide to go the custom development route, then the question of who owns the code is an important one.\r\n<span style=\"font-weight: bold;\">I’m thinking about hiring someone offshore; what should I watch out for?</span>\r\nIn short, everything. Language barriers and lack of proximity lead to breakdowns in communication and quality. Do yourself a favor and stay local.\r\nOn a related note, if you’re thinking about hiring for the position internally, think about this: it takes around three people to complete a successful custom software project. If you hire someone internally, their salary might cost what it would take to build with us, and you get a whole team when you work with us. Plus, if your software developer decides to leave, they take their knowledge with them. If one of our team members leave, our whole team shares the knowledge so you’re not left in the dark.\r\n<span style=\"font-weight: bold;\">If things don’t go well, am I sunk?</span>\r\nWe make communication and transparency are top priorities so this doesn’t happen. Right out of the gate we work hard to make sure that not only the project is a good fit, but the relationship with the client is as well. Through each step of the process and the build, we keep you in the loop weekly so you know what to expect and what is happening, but a good development company should have places in their process/relationship where you can cleanly exit. Make sure you know what the process is for leaving and what those different ‘leaving’ options are.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Custom_Software_Development.png","alias":"custom-software-development"},"605":{"id":605,"title":"Java Development","description":" Java is a general-purpose programming language that is class-based, object-oriented, and designed to have as few implementation dependencies as possible. 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.

It includes a large class library named Framework Class Library (FCL) and provides language interoperability (each language can use code written in other languages) across several programming languages. Programs written for .NET Framework execute in a software environment (in contrast to a hardware environment) named Common Language Runtime (CLR), an application virtual machine that provides services such as security, memory management, and exception handling. As such, computer code written using .NET Framework is called &quot;managed code&quot;. FCL and CLR together constitute the .NET Framework.\r\nFCL provides user interface, data access, database connectivity, cryptography, web application development, numeric algorithms, and network communications. Programmers produce software by combining their source code with .NET Framework and other libraries. The framework is intended to be used by most new applications created for the Windows platform. Microsoft also produces an integrated development environment largely for .NET software called Visual Studio.\r\n.NET Framework began as proprietary software, although the firm worked to standardize the software stack almost immediately, even before its first release. Despite the standardization efforts, developers, mainly those in the free and open-source software communities, expressed their unease with the selected terms and the prospects of any free and open-source implementation, especially regarding software patents. Since then, Microsoft has changed .NET development to more closely follow a contemporary model of a community-developed software project, including issuing an update to its patent promising to address the concerns.\r\n.NET Framework led to a family of .NET platforms targeting mobile computing, embedded devices, alternative operating systems, and web browser plug-ins. A reduced version of the framework, .NET Compact Framework, is available on Windows CE platforms, including Windows Mobile devices such as smartphones. .NET Micro Framework is targeted at very resource-constrained embedded devices. Silverlight was available as a web browser plugin. Mono is available for many operating systems and is customized into popular smartphone operating systems (Android and iOS) and game engines. .NET Core targets the Universal Windows Platform (UWP), and cross-platform and cloud computing workloads.","materialsDescription":"When Microsoft formally introduced its .NET strategy in mid-2000, analysts were confused about how the company would pull off such a massive platform shift. Over two years later, they're still wondering. But .NET isn't vaporware, and it's not a pipe dream. In fact, .NET is happening today.\r\n<span style=\"font-weight: bold; \">What is .NET?</span>\r\nActually, .NET is many things, but primarily it's a marketing term for a set of products and technologies that Microsoft is creating to move personal and enterprise computing beyond the PC desktop and into a distributed Internet-based environment. So .NET--which was originally called Next Generation Windows Services (NGWS)--is also a platform, one that Microsoft sees as the successor to Windows. The .NET platform is based on Web services which are, in turn, defined by a language called XML.\r\n<span style=\"font-weight: bold; \">What is XML?</span>\r\nXML--the eXtensible Markup Language--is a self-descriptive, data definition language. It's structure is similar to HTML, the language of the Web, but it's far more powerful because it's not limited to a static list of language constructs (&quot;tags&quot;) that the language's authors supply. Instead, XML is extensible and dynamic: Programmers can define new types of data using XML and then describe that data so that others will know how to use it.\r\n<span style=\"font-weight: bold; \">What are Web services?</span>\r\nWeb services are functions exposed by server-side applications. They are programmable units that other applications (and Web services) can access over the Internet.\r\n<span style=\"font-weight: bold; \">Does .NET require Windows?</span>\r\nTechnically, no, but realistically, yes. It's possible the .NET platform could be ported to other operating systems, such as Linux, FreeBSD, the Macintosh, or whatever, and indeed, some work is being done now in this area. However, .NET very much requires Windows today, on both the server and the client. One might say that .NET and Windows have a symbiotic relationship going forward.\r\n<span style=\"font-weight: bold; \">Is .NET is being ported to Linux?</span>\r\nYes. A company called Ximian is porting the standards-based parts of .NET to Linux as you read this, and the work is amazingly far along. Code-named Mono, this project seeks to bring the C# programming language, the Common Language Runtime (CLR, see below), and other .NET features to Linux.\r\nOn a related note, Microsoft has contracted Corel (makers of CorelDRAW and Word Perfect) to port .NET to FreeBSD.\r\n<span style=\"font-weight: bold; \">Isn't .NET just another name for COM, COM+, Windows DNA, or some other previous Windows technology?</span>\r\nActually, no. Microsoft spent considerable time and effort developing and promoting a set of Windows technologies that was at various times called OLE, COM, COM+, and Windows DNA (Distributed InterNet Architecture) but .NET is not the next iteration. Windows DNA, which was the final umbrella term for this set of technologies, was based around a concept where Windows-based software components could expose their services for other local and remote Windows software components. But though this sounds passingly similar to .NET, Windows DNA is very much based on proprietary Windows technologies. By comparison, .NET is based on open standards (XML and various related technologies), so it will be much easier for other vendors to adopt the platform and write compatible software. So we can eventually expect to see .NET clients and servers on platforms other than Windows.\r\n<span style=\"font-weight: bold; \">So what technologies are part of .NET?</span>\r\n.NET is comprised of several related technologies, including:\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">.NET Framework</span></span> - A runtime environment and set of standard services which .NET capable applications and services can utilize. Implemented as a code library, the .NET Framework includes the Common Language Runtime (CLR), the .NET run-time environment; ASP .NET, a Web applications platform; and ADO .NET, for data store access.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">.NET Compact Framework</span></span> - A subset of the .NET Framework designed for Pocket PCs, Microsoft Smart Phones, and other Windows CE .NET-based mobile devices.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">MSN consumer services</span></span> - Microsoft will use its consumer-oriented MSN online service to expose Web services to individuals. The current version, MSN 8, includes the .NET Passport's authentication services, email, address book, calendaring and tasks, and other similar services.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">.NET Enterprise Servers</span></span> - An extensive set of Microsoft server software that runs on Windows servers, including Application Server, BizTalk Server, Exchange Server, Host Integration Server, Internet Security and Acceleration Server, SQL Server, and many others. Microsoft is currently shipping many such server products, but they are all based on Windows DNA currently, not .NET. Future server products--beginning with Windows .NET Server 2003, due in April 2003--will actually be based on .NET technologies for the first time.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Visual Studio .NET</span></span> - Microsoft's .NET development environment, with support for languages such as Visual Basic .NET, Visual C++ .NET, Visual C# .NET, and Visual J#, which all target the .NET Framework. Other vendors can add other language capabilities to Visual Studio .NET, and the suite can be used to target a wide range of applications and services, including .NET Web services, Windows applications, and Web applications. Note that Visual Studio .NET is not required to create .NET applications and services: Developers can download the .NET Framework for free; this download includes compilers for Visual Basic .NET, Visual C++ .NET and Visual C# .NET.\r\n<span style=\"font-weight: bold;\">OK, so what's the point? How does this make my life better?</span>\r\nWith apologies to Microsoft for stealing the term, .NET enables a better PC ecosystem. That is, by making life easier for everyone involved with PCs, the benefits are cross-pollinated. Here's how .NET makes life easier on various groups:\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Programmers</span></span> - Because developers now have a consistent, language-neutral programming environment, they can create better applications and services more quickly. And because .NET encompasses such a wider range of functionality, those applications and services can be connected to back-end services via the Internet, offering better, and more exciting functionality.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">IT administrators</span></span> - Because .NET applications and services do away with the &quot;DLL Hell&quot; found in previous Windows applications, they are amazingly easy to distribute and install.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">End users</span></span> - For the reasons listed above, and many others, a new generation of .NET applications and services will provide new types of connected functionality. Access your email from anywhere. Pay for products online without typing in your credit card information. Access weather, traffic, music, and other personal information from a variety of devices, from anywhere in the world.

Each structure comprises software elements, relations among them, and properties of both elements and relations. The architecture of a software system is a metaphor, analogous to the architecture of a building. It functions as a blueprint for the system and the developing project, laying out the tasks necessary to be executed by the design teams.\r\nSoftware architecture is about making fundamental structural choices that are costly to change once implemented. Software architecture choices include specific structural options from possibilities in the design of the software. For example, the systems that controlled the Space Shuttle launch vehicle had the requirement of being very fast and very reliable. Therefore, an appropriate real-time computing language would need to be chosen. Additionally, to satisfy the need for reliability the choice could be made to have multiple redundant and independently produced copies of the program, and to run these copies on independent hardware while cross-checking results.\r\nDocumenting software architecture facilitates communication between stakeholders, captures early decisions about the high-level design, and allows the reuse of design components between projects.","materialsDescription":" <span style=\"font-weight: bold; \">What is the scope of software architecture?</span>\r\nOpinions vary as to the scope of software architectures:\r\n<ul><li>Macroscopic system structure: this refers to architecture as a higher-level abstraction of a software system that consists of a collection of computational components together with connectors that describe the interaction between these components.</li><li>The important stuff—whatever that is: this refers to the fact that software architects should concern themselves with those decisions that have a high impact on the system and its stakeholders.</li><li>That is fundamental to understanding a system in its environment.</li><li>Things that people perceive as hard to change: since designing the architecture takes place at the beginning of a software system's lifecycle, the architect should focus on decisions that &quot;have to&quot; be right the first time. Following this line of thought, architectural design issues may become non-architectural once their irreversibility can be overcome.</li><li>A set of architectural design decisions: software architecture should not be considered merely a set of models or structures, but should include the decisions that lead to these particular structures, and the rationale behind them. This insight has led to substantial research into software architecture knowledge management.</li></ul>\r\n<span style=\"font-weight: bold; \">What are the characteristics of software architecture?</span>\r\nSoftware architecture exhibits the following:\r\n<span style=\"font-weight: bold; \">A multitude of stakeholders:</span> software systems have to cater to a variety of stakeholders such as business managers, owners, users, and operators. These stakeholders all have their own concerns with respect to the system. Balancing these concerns and demonstrating that they are addressed is part of designing the system. This implies that architecture involves dealing with a broad variety of concerns and stakeholders, and has a multidisciplinary nature.\r\n<span style=\"font-weight: bold; \">Separation of concerns:</span> the established way for architects to reduce complexity is to separate the concerns that drive the design. Architecture documentation shows that all stakeholder concerns are addressed by modeling and describing the architecture from separate points of view associated with the various stakeholder concerns. These separate descriptions are called architectural views.\r\n<span style=\"font-weight: bold; \">Quality-driven:</span> classic software design approaches (e.g. Jackson Structured Programming) were driven by required functionality and the flow of data through the system, but the current insight is that the architecture of a software system is more closely related to its quality attributes such as fault-tolerance, backward compatibility, extensibility, reliability, maintainability, availability, security, usability, and other such –ilities. Stakeholder concerns often translate into requirements on these quality attributes, which are variously called non-functional requirements, extra-functional requirements, behavioral requirements, or quality attribute requirements.\r\n<span style=\"font-weight: bold; \">Recurring styles:</span> like building architecture, the software architecture discipline has developed standard ways to address recurring concerns. These &quot;standard ways&quot; are called by various names at various levels of abstraction. Common terms for recurring solutions are architectural style, tactic, reference architecture and architectural pattern.\r\n<span style=\"font-weight: bold; \">Conceptual integrity:</span> a term introduced by Fred Brooks in The Mythical Man-Month to denote the idea that the architecture of a software system represents an overall vision of what it should do and how it should do it. This vision should be separated from its implementation. The architect assumes the role of &quot;keeper of the vision&quot;, making sure that additions to the system are in line with the architecture, hence preserving conceptual integrity.\r\n<span style=\"font-weight: bold; \">Cognitive constraints:</span> an observation first made in a 1967 paper by computer programmer Melvin Conway that organizations which design systems are constrained to produce designs which are copies of the communication structures of these organizations. As with conceptual integrity, it was Fred Brooks who introduced it to a wider audience when he cited the paper and the idea in his elegant classic The Mythical Man-Month, calling it &quot;Conway's Law.&quot;\r\n<span style=\"font-weight: bold;\">What is the motivation of software architecture?</span>\r\nSoftware architecture is an &quot;intellectually graspable&quot; abstraction of a complex system. This abstraction provides a number of benefits:\r\n<ul><li><span style=\"font-style: italic;\">It gives a basis for an analysis of software systems' behavior before the system has been built.</span> The ability to verify that a future software system fulfills its stakeholders' needs without actually having to build it represents substantial cost-saving and risk-mitigation. A number of techniques have been developed to perform such analyses, such as ATAM.</li><li><span style=\"font-style: italic;\">It provides a basis for the re-use of elements and decisions.</span> A complete software architecture or parts of it, like individual architectural strategies and decisions, can be re-used across multiple systems whose stakeholders require similar quality attributes or functionality, saving design costs and mitigating the risk of design mistakes.</li><li><span style=\"font-style: italic;\">It supports early design decisions that impact a system's development, deployment, and maintenance life.</span> Getting the early, high-impact decisions right is important to prevent schedule and budget overruns.</li><li><span style=\"font-style: italic;\">It facilitates communication with stakeholders, contributing to a system that better fulfills their needs.</span> Communicating about complex systems from the point of view of stakeholders helps them understand the consequences of their stated requirements and the design decisions based on them. Architecture gives the ability to communicate about design decisions before the system is implemented when they are still relatively easy to adapt.</li><li><span style=\"font-style: italic;\">It helps in risk management.</span> Software architecture helps to reduce risks and the chance of failure.</li><li><span style=\"font-style: italic;\">It enables cost reduction.</span> Software architecture is a means to manage risk and costs in complex IT projects.</li></ul>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Software_Architecture_Design.png","alias":"software-architecture-design"},"685":{"id":685,"title":"Database Administration","description":" Database administration refers to the whole set of activities performed by a database administrator to ensure that a database is always available as needed. Other closely related tasks and roles are database security, database monitoring and troubleshooting, and planning for future growth.\r\nDatabase administration is an important function in any organization that is dependent on one or more databases.\r\nThe database administrator (DBA) is usually a dedicated role in the IT department for large organizations. However, many smaller companies that cannot afford a full-time DBA usually outsource or contract the role to a specialized vendor, or merge the role with another in the ICT department so that both are performed by one person.\r\nThe primary role of database administration is to ensure maximum up time for the database so that it is always available when needed. This will typically involve proactive periodic monitoring and troubleshooting. This in turn entails some technical skills on the part of the DBA. In addition to in-depth knowledge of the database in question, the DBA will also need knowledge and perhaps training in the platform (database engine and operating system) on which the database runs.\r\nA DBA is typically also responsible for other secondary, but still critically important, tasks and roles. Some of these include:\r\n<ul><li>Database Security: Ensuring that only authorized users have access to the database and fortifying it against any external, unauthorized access.</li><li>Database Tuning: Tweaking any of several parameters to optimize performance, such as server memory allocation, file fragmentation and disk usage.</li><li>Backup and Recovery: It is a DBA's role to ensure that the database has adequate backup and recovery procedures in place to recover from any accidental or deliberate loss of data.</li><li>Producing Reports from Queries: DBAs are frequently called upon to generate reports by writing queries, which are then run against the database.</li></ul>\r\nIt is clear from all the above that the database administration function requires technical training and years of experience. Some companies that offer commercial database products, such as Oracle DB and Microsoft's SQL Server, also offer certifications for their specific products. These industry certifications, such as Oracle Certified Professional (OCP) and Microsoft Certified Database Administrator (MCDBA), go a long way toward assuring organizations that a DBA is indeed thoroughly trained on the product in question. Because most relational database products today use the SQL language, knowledge of SQL commands and syntax is also a valuable asset for today's DBAs.","materialsDescription":" <span style=\"font-weight: bold;\">Data Resource Management</span>\r\nAccording to the Data Management Association (DAMA), data resource management is &quot;the development and execution of architectures, policies, practices and procedures that properly manage the full data lifecycle needs of an enterprise&quot;. Data Resource management may be thought of as a managerial activity that applies information system and other data management tools to the task of managing an organization’s data resource to meet a company’s business needs, and the information they provide to their shareholders. From the perspective of database design, it refers to the development and maintenance of data models to facilitate data sharing between different systems, particularly in a corporate context. Data Resource Management is also concerned with both data quality and compatibility between data models.\r\nSince the beginning of the information age, businesses need all types of data on their business activity. With each data created, when a business transaction is made, need data is created. With these data, new direction is needed that focuses on managing data as a critical resource of the organization to directly support its business activities. The data resource must be managed with the same intensity and formality that other critical resources are managed. Organizations must emphasize the information aspect of information technology, determine the data needed to support the business, and then use appropriate technology to build and maintain a high-quality data resource that provides that support.\r\nData resource quality is a measure of how well the organization's data resource supports the current and the future business information demand of the organization. The data resource cannot support just the current business information demand while sacrificing the future business information demand. It must support both the current and the future business information demand. The ultimate data resource quality is stability across changing business needs and changing technology.\r\nA corporate data resource must be developed within single, organization-wide common data architecture. A data architecture is the science and method of designing and constructing a data resource that is business driven, based on real-world objects and events as perceived by the organization, and implemented into appropriate operating environments. It is the overall structure of a data resource that provides a consistent foundation across organizational boundaries to provide easily identifiable, readily available, high-quality data to support the business information demand.\r\nThe common data architecture is a formal, comprehensive data architecture that provides a common context within which all data at an organization's disposal are understood and integrated. It is subject oriented, meaning that it is built from data subjects that represent business objects and business events in the real world that are of interest to the organization and about which data are captured and maintained.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Database_Administration.png","alias":"database-administration"},"693":{"id":693,"title":"Linux Administration","description":" Linux is an operating system or a kernel created by Linus Torvalds with other contributors.

Even freshman-level Professionals has great possibilities for the position of System Administrator with the yearly median salary is around INR 3 Lacs, salary increase with an increase in job experience.","materialsDescription":" <span style=\"font-weight: bold;\">What Is Linux?</span>\r\nLinux is the kernel of operating systems that look like and perform as well or better than the famous operating system from AT&amp;T Bell Labs. Linus Torvalds and a loosely-knit team of volunteer hackers from across the Internet wrote (and still are writing) Linux from scratch. It has all of the features of a modern, fully-fledged operating system: true multitasking, threads, virtual memory, shared libraries, demand loading, shared, copy-on-write executables, proper memory management, loadable device driver modules, video frame buffering, and TCP/IP networking.\r\nMost people, however, refer to the operating system kernel, system software, and application software, collectively, as &quot;Linux,'' and that convention is used in this FAQ as well.\r\nLinux was written originally for 386/486/586-based PC's, using the hardware facilities of the 80386 processor family to implement its features. There are now many ports to other hardware platforms.\r\nThere are also Linux distributions specifically for mobile and handheld platforms. An API specification and developers kit for the Crusoe Smart Microprocessor developed by Transmeta Corporation is at <link http://www.transmeta.com/>http://www.transmeta.com/</link> The Linux kernel is distributed under the GNU General Public License.\r\n<span style=\"font-weight: bold;\">What Hardware Is Supported?</span>\r\nA minimal Linux installation requires a machine for which a port exists, at least 2Mb of RAM, and a single floppy drive. But to do anything even remotely useful, more RAM and disk space are needed.\r\nIntel CPU, PC-compatible machines require at least an 80386 processor to run the standard Linux kernel. Linux, including the X Window System GUI, runs on most current laptops.\r\n<span style=\"font-weight: bold;\">What are the duties of a Linux Administrator?</span>\r\nSystem Administration has become a solid criterion for an organization and institute that requires a solid IT foundation. Hence, the need for efficient Linux administrators is the requirement of the time. The job profile might change from each organization as there may be added responsibilities and duties to the role. Below are some duties of a Linux Administrator:\r\n<ul><li>Maintain all internet requests inclusive to DNS, RADIUS, Apache, MySQL, PHP.</li><li>Taking regular back up of data, create new stored procedures and listing back-up is one of the duties.</li><li>Analyzing all error logs and fixing along with providing excellent customer support for Webhosting, ISP and LAN Customers on troubleshooting increased support troubles.</li><li>Communicating with the staff, vendors, and customers in a cultivated, professional manner at all times has to be one of his characteristics.</li><li>Enhance, maintain and creating the tools for the Linux environment and its users.</li><li>Detecting and solving the service problems ranging from disaster recovery to login problems.</li><li>Installing the necessary systems and security tools.

There are sometimes overlaps between the two fields, but IT consultants often have degrees in computer science, electronics, technology, or management information systems while management consultants often have degrees in accounting, economics, Industrial Engineering, finance, or a generalized MBA (Masters in Business Administration).\r\nAccording to the Institute for Partner Education &amp; Development, IT consultants' revenues come predominantly from design and planning based consulting with a mixture of IT and business consulting. This is different from a systems integrator in that you do not normally take title to product. Their value comes from their ability to integrate and support technologies as well as determining product and brands. ","materialsDescription":"<span style=\"font-weight: bold; \">Who is an information technology (IT) consultant?</span>\r\nAn information technology consultant is a third-party service provider who is qualified to advise clients on the best use of IT to meet specific business requirements. IT consultants may work with a professional IT consultancy firm or as independent contractors. They may conduct a business needs assessment and develop an information systems solution that meets the organization's objectives.\r\nSome information technology consultants emphasize technical issues while others help organizations use IT to manage business processes. Still others specialize in a specific IT area such as information security.\r\nIT consultants need a deep knowledge of both business and information technology. A bachelor's degree in management information systems, computer science, or information science is the typical path into a technical consultancy career. IT certifications supplement this foundation with specialized technical training. Information technology degree and certification programs are available online to accommodate working IT professionals.\r\n<span style=\"font-weight: bold; \">What are the prerequisites and major obstacles?</span>\r\nOnce a business owner defined the needs to take a business to the next level, a decision maker will define a scope, cost and a time-frame of the project. The role of the IT consultancy company is to support and nurture the company from the very beginning of the project until the end, and deliver the project not only in the scope, time and cost but also with complete customer satisfaction.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Project scoping and planning</span></span>\r\nThe usual problem is that a business owner doesn't know the detail of what the project is going to deliver until it starts the process. In many cases, the incremental effort in some projects can lead to significant financial loss.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Business process and system design</span></span>\r\nThe scope of a project is linked intimately to the proposed business processes and systems that the project is going to deliver. Regardless of whether the project is to launch a new product range or discontinue unprofitable parts of the business, the change will have some impact on business processes and systems. The documentation of your business processes and system requirements are as fundamental to project scoping as an architects plans would be to the costing and scoping of the construction of a building.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Project management support</span></span>\r\nThe most successful business projects are always those that are driven by an employee who has the authority, vision and influence to drive the required changes in a business. It is highly unlikely that a business owner (decision maker or similar) will realize the changes unless one has one of these people in the employment. However, the project leadership role typically requires significant experience and skills which are not usually found within a company focused on day-to-day operations. Due to this requirement within more significant business change projects/programs, outside expertise is often sought from firms which can bring this specific skill set to the company.\r\n<span style=\"font-weight: bold;\">What are the skills of IT-consulting?</span>\r\nAn IT consultant needs to possess the following skills:\r\n<ul><li>Advisory skills</li><li>Technical skills</li><li>Business skills</li><li>Communication skills</li><li>Management skills</li><li>Advisory language skills</li><li>Business and management language skills</li><li>Technical language skills</li></ul>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_IT_Consulting.png","alias":"it-consulting"},"733":{"id":733,"title":"Technical Support","description":" Technical support (often shortened to tech support) refers to services that entities provide to users of technology products or services. In general, technical support provide help regarding specific problems with a product or service, rather than providing training, provision or customization of product, or other support services. Most companies offer technical support for the services or products they sell, either included in the cost or for an additional fee. Technical support may be delivered over by phone, e-mail, live support software on a website, or other tool where users can log an incident. Larger organizations frequently have internal technical support available to their staff for computer-related problems. The Internet can also be a good source for freely available tech support, where experienced users help users find solutions to their problems. In addition, some fee-based service companies charge for premium technical support services.\r\nTechnical support may be delivered by different technologies depending on the situation. For example, direct questions can be addressed using telephone calls, SMS, Online chat, Support Forums, E-mail or Fax; basic software problems can be addressed over the telephone or, increasingly, by using remote access repair services; while more complicated problems with hardware may need to be dealt with in person.\r\nTechnical support is a range of services providing assistance with technology such as televisions, computers, and software, typically aiming to help the user with a specific problem.","materialsDescription":"<span style=\"font-weight: bold; \">What are the categories of technical support?</span>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Call in</span></span>\r\nThis type of technical support has been very common in the services industry.[citation needed] It is also known as &quot;Time and Materials&quot; (T&amp;M) IT support.[citation needed] The customer pays for the materials (hard drive, memory, computer, digital devices, etc.) and also pays the technician based on the pre-negotiated rate when a problem occurs.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Block hours</span></span>\r\nBlock hours allow the client to purchase a number of hours upfront at an agreed price. While it is commonly used to offer a reduced hourly rate, it can also simply be a standard non-reduced rate, or represent a minimum fee charged to a client before providing service. The premise behind this type of support is that the customer has purchased a fixed number of hours to use either per month or year. This allows them the flexibility to use the hours as they please without doing the paperwork and the hassle of paying multiple bills.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Managed services</span></span>\r\nManaged services means a company will receive a list of well-defined services on an ongoing basis, with well-defined &quot;response and resolution times&quot; for a fixed rate or a flat fee. This can include things like 24/7 monitoring of servers, 24/7 help desk support for daily computer issues, and on-site visits by a technician when issues cannot be resolved remotely.[citation needed] Some companies also offer additional services like project management, backup and disaster recovery, and vendor management in the monthly price. The companies that offer this type of tech support are known as managed services providers.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Crowdsourced technical support</span></span>\r\nMany companies and organizations provide discussion boards for users of their products to interact; such forums allow companies to reduce their support costs without losing the benefit of customer feedback.\r\n<span style=\"font-weight: bold;\">What is outsourcing technical support?</span>\r\nWith the increasing use of technology in modern times, there is a growing requirement to provide technical support. Many organizations locate their technical support departments or call centers in countries or regions with lower costs. Dell was amongst the first companies to outsource their technical support and customer service departments to India in 2001. There has also been a growth in companies specializing in providing technical support to other organizations. These are often referred to as MSPs (Managed Service Providers).\r\nFor businesses needing to provide technical support, outsourcing allows them to maintain a high availability of service. Such need may result from peaks in call volumes during the day, periods of high activity due to introduction of new products or maintenance service packs, or the requirement to provide customers with a high level of service at a low cost to the business. For businesses needing technical support assets, outsourcing enables their core employees to focus more on their work in order to maintain productivity. It also enables them to utilize specialized personnel whose technical knowledge base and experience may exceed the scope of the business, thus providing a higher level of technical support to their employees.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Technical_Support.png","alias":"technical-support"},"737":{"id":737,"title":"IT System Testing","description":" System testing is testing conducted on a complete integrated system to evaluate the system's compliance with its specified requirements.\r\nSystem testing takes, as its input, all of the integrated components that have passed integration testing. The purpose of integration testing is to detect any inconsistencies between the units that are integrated together (called assemblages). System testing seeks to detect defects both within the &quot;inter-assemblages&quot; and also within the system as a whole. The actual result is the behavior produced or observed when a component or system is tested.\r\nSystem testing is performed on the entire system in the context of either functional requirement specifications (FRS) or system requirement specification (SRS), or both. System testing tests not only the design but also the behavior and even the believed expectations of the customer. It is also intended to test up to and beyond the bounds defined in the software or hardware requirements specification(s).\r\nSoftware testing is an investigation conducted to provide stakeholders with information about the quality of the software product or service under test. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Software testing involves the execution of a software component or system component to evaluate one or more properties of interest. In general, these properties indicate the extent to which the component or system under test meets the requirements that guided its design and development, responds correctly to all kinds of inputs, performs its functions within an acceptable time, is sufficiently usable, can be installed and run in its intended environments, and achieves the general result its stakeholders desire. As the number of possible tests for even simple software components is practically infinite, all software testing uses some strategy to select tests that are feasible for the available time and resources.\r\nMobile-device testing assures the quality of mobile devices, like mobile phones, PDAs, etc. The testing will be conducted on both hardware and software. And from the view of different procedures, the testing comprises R&amp;D testing, factory testing and certification testing. Mobile-device testing involves a set of activities from monitoring and troubleshooting mobile applications, content and services on real handsets. Testing includes verification and validation of hardware devices and software applications.","materialsDescription":" <span style=\"font-weight: bold;\">What is System Testing?</span>\r\nSystem Testing is the testing of a complete and fully integrated software product. Usually, the software is only one element of a larger computer-based system. Ultimately, the software is interfaced with other software/hardware systems. System Testing is actually a series of different tests whose sole purpose is to exercise the full computer-based system.\r\nTwo Category of Software Testing:\r\n<ul><li>Black Box Testing;</li><li>White Box Testing.</li></ul>\r\nSystem test falls under the black box testing category of software testing.\r\nWhite box testing is the testing of the internal workings or code of a software application. In contrast, black box or System Testing is the opposite. The system test involves the external workings of the software from the user's perspective.\r\n<span style=\"font-weight: bold;\">What do you verify in System Testing?</span>\r\nSystem Testing involves testing the software code for following:\r\n<ul><li>Testing the fully integrated applications including external peripherals in order to check how components interact with one another and with the system as a whole. This is also called End to End testing scenario.</li><li>Verify thorough testing of every input in the application to check for desired outputs.</li><li>Testing of the user's experience with the application.</li></ul>\r\nThat is a very basic description of what is involved in system testing. You need to build detailed test cases and test suites that test each aspect of the application as seen from the outside without looking at the actual source code.\r\n<span style=\"font-weight: bold;\">What Types of System Testing Should Testers Use?</span>\r\nThere are over 50 different types of system testing. The specific types used by a tester depend on several variables. Those variables include:\r\n<ul><li><span style=\"font-weight: bold;\">Who the tester works for</span> - This is a major factor in determining the types of system testing a tester will use. Methods used by large companies are different than those used by medium and small companies.</li><li><span style=\"font-weight: bold;\">Time available for testing</span> - Ultimately, all 50 testing types could be used. Time is often what limits us to using only the types that are most relevant for the software project.</li><li><span style=\"font-weight: bold;\">Resources available to the tester</span> - Of course some testers will not have the necessary resources to conduct a testing type. For example, if you are a tester working for a large software development firm, you are likely to have expensive automated testing software not available to others.</li><li><span style=\"font-weight: bold;\">Software Tester's Education</span> - There is a certain learning curve for each type of software testing available. To use some of the software involved, a tester has to learn how to use it.</li><li><span style=\"font-weight: bold;\">Testing Budget</span> - Money becomes a factor not just for smaller companies and individual software developers but large companies as well.</li></ul>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_IT_System_testing.png","alias":"it-system-testing"},"739":{"id":739,"title":"Deployment and Integration Services","description":" The number of various solutions implemented by customers today is quite large. Often, the subsystems of the seemingly unified IT landscape are either weakly connected with each other, or the interaction between them is established in the mode of transferring files and data by mail or “from hand to hand”.\r\nWestern IT vendors, following a certain trend, offer the customer complete and unified solutions. Such blocks of subsystems solve a specific task and form separate IT centers, which also require the mutual integration of infrastructures. This, oddly enough, is even more difficult, as a complete solution does not allow to penetrate deeply and get access to the required information or control subsystems.\r\nNevertheless, the integration and interconnection of information flows can significantly simplify business processes and lead to an increase in the efficiency of interaction both inside and outside the company (with customers and partners).\r\nThe integration task itself is important for business, as it provides a qualitatively new level of services. This is especially important for companies where IT is the immediate tool for achieving business goals.
