These types of databases allow users to do more than simply view archived data. Operational databases allow you to modify that data (add, change or delete data), doing it in real-time. OLTP databases provide transactions as the main abstraction to guarantee data consistency that guarantees the so-called ACID properties. Basically, the consistency of the data is guaranteed in the case of failures and/or concurrent access to the data.\r\nSince the early 90s, the operational database software market has been largely taken over by SQL engines. Today, the operational DBMS market (formerly OLTP) is evolving dramatically, with new, innovative entrants and incumbents supporting the growing use of unstructured data and NoSQL DBMS engines, as well as XML databases and NewSQL databases. NoSQL databases typically have focused on scalability and have renounced to data consistency by not providing transactions as OLTP systems do. Operational databases are increasingly supporting distributed database architecture that can leverage distribution to provide high availability and fault tolerance through replication and scale-out ability.\r\nThe growing role of operational databases in the IT industry is moving fast from legacy databases to real-time operational databases capable to handle distributed web and mobile demand and to address Big data challenges. Recognizing this, Gartner started to publish the Magic Quadrant for Operational Database Management Systems in October 2013.\r\nOperational databases are used to store, manage and track real-time business information. For example, a company might have an operational database used to track warehouse/stock quantities. As customers order products from an online web store, an operational database can be used to keep track of how many items have been sold and when the company will need to reorder stock. An operational database stores information about the activities of an organization, for example, customer relationship management transactions or financial operations, in a computer database.\r\nOperational databases allow a business to enter, gather, and retrieve large quantities of specific information, such as company legal data, financial data, call data records, personal employee information, sales data, customer data, data on assets and much other information. An important feature of storing information in an operational database is the ability to share information across the company and over the Internet. Operational databases can be used to manage mission-critical business data, to monitor activities, to audit suspicious transactions, or to review the history of dealings with a particular customer. They can also be part of the actual process of making and fulfilling a purchase, for example in e-commerce.","materialsDescription":" <span style=\"font-weight: bold;\">What is DBMS used for?</span>\r\nDBMS, commonly known as Database Management System, is an application system whose main purpose revolves around the data.

Product life management concepts were first introduced where safety and control have been extremely important, notably the aerospace, medical device, military and nuclear industries. These industries originated the discipline of configuration management (CM), which evolved into electronic data management systems (EDMS), which then further evolved to product data management (PDM).\r\nOver the last ten years, manufacturers of instrumentation, industrial machinery, consumer electronics, packaged goods and other complex engineered products have discovered the benefits of PLM management and are adopting efficient PLM software in increasing numbers.\r\n<p class=\"align-center\"><span style=\"font-weight: bold;\">The PLM Stages</span></p>\r\n<span style=\"font-weight: bold; \">Beginning of Life (BOL):</span> The beginning of life phase includes all of the design and manufacturing, which consists of the initial conceptualization and development, and any prototypes built. Initial development has multiple sub-actions that identify all the requirements, concepts, and necessary testing. \r\n<span style=\"font-weight: bold; \">Middle of Life (MOL):</span> The middle of life phase is post-manufacturing, when your product is distributed, used, and serviced. At this point, your product is in the hands of the end user. You can collect data on any failures, maintenance rates, and user experience to get information for immediate fixes and future development.\r\n<span style=\"font-weight: bold; \">End of Life (EOL):</span> The end of life phase is the retiring, recycling, or disposing of your product. At this point, the reverse logistics happen for the company. EOL starts when users no longer have a need for the product. At this stage, companies collect information about what parts and materials are still valuable.\r\n<span style=\"font-weight: bold;\">Product lifecycle management software</span> is used to deliver all kinds of products to market, which means there are a lot of different providers out there. Its purpose today is to help organizations: \r\n<ol><li>Develop new products using CAD software</li><li>Produce and manufacture new products</li><li>Bring those products to market</li></ol>\r\nAnd increasingly, product life management software has to process the feedback from the market back to the design and production processes. To achieve these goals, product lifecycle management solutions have to do four things:\r\n<ul><li>Link together CAD metadata with a bill of materials</li><li>Manage workflows for organizations needed to bring products to market</li><li>Manage product data as they move through the product development lifecycle stages</li><li> Hook in auxiliary suppliers and business stakeholders to a shared version of truth or single source of truth.</li></ul>\r\n\r\n","materialsDescription":"<h1 class=\"align-center\">Top PLM System Software Requirements</h1>\r\n<span style=\"font-weight: bold; \">Bill of Materials.</span> Having a common source of information across your company is incredibly important during product development. That’s why a bill of materials (BOM) is key to include in your list of product lifecycle management requirements. At the very least, your system should provide a single definition of a particular product and its components. More advanced options include features specifically designed for different team members such as designers, engineers and other professionals who frequently&nbsp; collaborate.\r\n<span style=\"font-weight: bold; \">Computer-Aided Design Management.</span> Managing your CAD activities and documents is more than useful when it comes to PLM. Your solution should be able to manage changes to product configurations while maintaining the functional and physical attributes of a product throughout its lifecycle. Production engineering changes should proliferate throughout your processes, with the changes evident in the subsequent BOMs and plans.\r\n<span style=\"font-weight: bold; \">Manufacturing Product Management.</span> During a product’s lifecycle, you want to keep an eye on your portfolio. With portfolio management, users can determine the proper investment balance to maximize their research and development investment returns. Some systems provide strategy tools to spotlight priorities and support planning. Top PLM software can even determine the best possible investment scenario. Users can also track project progress to completion, which is automatically documented in the product record. This allows greater insight into your processes, facilitating better resource management and allocation.\r\n<span style=\"font-weight: bold; \">Product Regulation and Governance.</span> Failing to follow regulation and compliance standards is one of the quickest ways to earn your business a bad reputation. But having the right tools built into your product life management system can make staying compliant much easier than it would be otherwise. Your solution should be able to centralize relevant information and documentation, making it easier for enterprise organizations to achieve and maintain compliance.&nbsp; You also may choose a system that can comply with medical, environmental, safety, FSA and ISO standards depending on your industry.\r\n<span style=\"font-weight: bold; \">Project and Component Maintenance.</span> Project management tools are vital for providing users visibility into daily processes and progress. These features include tracking and scheduling capabilities, which enable you to manage product development along with resource allocation in real time. Users can also see upcoming milestones and constraints for further planning.\r\n<span style=\"font-weight: bold; \">Quote Process Management.</span> Data from many different sources is often needed during the quote process. PLM’s inherent coordination capabilities gather and organize data pertaining to product design to support your engineering teams. This includes teams developing engineer-to-order and configure-to-order products. The system only shares the necessary data, meaning your team members can spend more time focusing on their work and less on hunting down information. \r\n<span style=\"font-weight: bold; \">Risk Management. </span>This feature brings risks to users’ attention, allowing them to manage, report and mitigate those instabilities. Reducing risks early on prevents issues from growing as they move through product development unseen, reducing the overall cost of development. Some systems do this by “detecting” or “highlighting” risks, whereas some systems simply offer full visibility through PM tools.\r\n<span style=\"font-weight: bold;\">Workflow and Change Management.</span> Plainly said, this suite of PLM software tools gives users insight into product activities. Users can determine phases for a project, as well as assign milestones to keep projects on track. Some systems allow users to see all pending and implemented changes, as well as all items that endure the subsequent effects. This visibility extends to portfolio and resource management, also.\r\n\r\n","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/PLM_-_Product_Lifecycle_Management.png","alias":"plm-product-lifecycle-management"},"82":{"id":82,"title":"Unified Communications","description":"Unified communications (UC) is a framework for integrating various asynchronous and real-time communication tools. The goal of UC is to enhance business communication, collaboration and productivity. Unified communications do not represent a singular technology; rather, it describes a strategy for integrating interconnected systems of enterprise communication devices and applications that can be used in concert or successively.\r\nSome business communication tools - like Internet Protocol (IP) telephony and video conferencing - facilitate real-time communication, also called synchronous communication. Other enterprise communication tools, like email, facilitate asynchronous communication, which takes place at a person's convenience.\r\nIncreasingly, team collaboration tools have emerged to offer messaging-centric workflows and near-real-time communication. These tools also offer voice and video capabilities, API integrations and, ultimately, expound on instant messaging services by providing better UC features.\r\nThe goal of unified communications is to integrate the software that supports synchronous and asynchronous communication, so the end user has easy access to all tools from whatever device is in use.\r\nA unified communications environment is typically supported by one or more back-end systems, often referred to as UC platforms, that facilitate integration among services, as well as the front-end clients that provide access. For example, a web conferencing system would make use of an audio conferencing system - which, in turn, would be built on an underlying IP telephony platform - and a unified messaging client would allow click-to-talk (CTC), click-to-chat or click-to-video functionality.\r\nUC also supports users moving from one mode of communication to another within the same session. For example, a user may start communicating via email but then decide to escalate the interaction to real-time communication, transitioning the session to a voice call with one click and then to a video conference with another click without any disruption.\r\nUnified communications systems and their components can be deployed on premises, in a public or private cloud, or a combination of all three. Cloud-based unified communications is also called UC as a service (UCaaS). An open source project called WebRTC, for example, enables real-time communications to be embedded into web browsers.\r\nHistorically, single-vendor UC environments have demonstrated the tightest integration and compatibility. Interoperability among vendors remains an ongoing challenge in UC, but it has also been mitigated, in part, by partnerships, common protocols and open APIs.","materialsDescription":" <span style=\"font-weight: bold;\">What technology do unified communications have?</span>\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Contrasting unified messaging</span></span>\r\nUnified communications are sometimes confused with unified messaging, but it is distinct. Unified communications refer to both real-time and non-real-time delivery of communications based on the preferred method and location of the recipient; unified messaging culls messages from several sources (such as e-mail, voice mail and faxes), but holds those messages only for retrieval at a later time. Unified communications allow for an individual to check and retrieve an e-mail or voice mail from any communication device at any time. It expands beyond voice mail services to data communications and video services.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Components</span></span>\r\nWith unified communications, multiple modes of business communications are integrated. Unified communications is not a single product but a collection of elements that include:\r\n<ul><li>Call control and multimodal communications</li><li>Presence</li><li>Instant messaging</li><li>Unified messaging</li><li>Speech access and personal assistant</li><li>Conferencing (audio, Web and video)</li><li>Collaboration tools</li><li>Mobility</li><li>Business process integration (BPI)</li><li>Software to enable business process integration</li></ul>\r\nPresence — knowing where intended recipients are, and if they are available, in real-time — is a key component of unified communications. Unified communications integrate all systems a user might already use, and helps those systems work together in real-time. For example, unified communications technology could allow a user to seamlessly collaborate with another person on a project, even if the two users are in separate locations. The user could quickly locate the necessary person by accessing an interactive directory, engage in a text messaging session, and then escalate the session to a voice call or even a video call.\r\nIn another example, an employee receives a call from a customer who wants answers. Unified communications enable that employee to call an expert colleague from a real-time list. This way, the employee can answer the customer faster by eliminating rounds of back-and-forth e-mails and phone-tag.\r\nThe examples in the previous paragraph primarily describe &quot;personal productivity&quot; enhancements that tend to benefit the individual user. While such benefits can be important, enterprises are finding that they can achieve even greater impact by using unified communications capabilities to transform business processes. This is achieved by integrating UC functionality directly into the business applications using development tools provided by many of the suppliers. Instead of the individual user invoking the UC functionality to, say, find an appropriate resource, the workflow or process application automatically identifies the resource at the point in the business activity where one is needed.\r\nWhen used in this manner, the concept of presence often changes. Most people associate presence with instant messaging (IM &quot;buddy lists&quot;) the status of individuals is identified. But, in many business process applications, what is important is finding someone with a certain skill. In these environments, presence identifies available skills or capabilities.\r\nThis &quot;business process&quot; approach to integrating UC functionality can result in bottom-line benefits that are an order of magnitude greater than those achievable by personal productivity methods alone.\r\n<span style=\"font-weight: bold;\">Related concepts</span>\r\nUnified communications &amp; collaboration (UCC) is the integration of various communications methods with collaboration tools such as virtual white boards, real-time audio and video conferencing, and enhanced call control capabilities. Before this fusion of communications and collaboration tools into a single platform, enterprise collaboration service vendors and enterprise communications service vendors offered distinctly different solutions. Now, collaboration service vendors also offer communications services, and communications service providers have developed collaboration tools.\r\nUnified communications &amp; collaboration as a service (UCCaaS) is cloud-based UCC platforms. Compared to premises-based UCC solutions, UCCaaS platforms offer enhanced flexibility and scalability due to the SaaS subscription model.\r\nUnified communications provisioning is the act of entering and configuring the settings for users of phone systems, instant messaging, telepresence, and other collaboration channels. Provisioners refer to this process as making moves, adds, changes, and deletes or MAC-Ds.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Unified_Communications.png","alias":"unified-communications"}},"companyUrl":"http://www.siemens.com/","countryCodes":[],"certifications":[],"isSeller":true,"isSupplier":false,"isVendor":true,"presenterCodeLng":"","seo":{"title":"Siemens","keywords":"Siemens, company, 2015, largest, around, pioneering, solutions, industry","description":"Siemens is a German company headquartered in Berlin and Munich and the largest engineering company in Europe with branch offices abroad.

By contrast, software is instructions that can be stored and run by hardware. Hardware is so-termed because it is &quot;hard&quot; or rigid with respect to changes or modifications; whereas software is &quot;soft&quot; because it is easy to update or change. Intermediate between software and hardware is &quot;firmware&quot;, which is software that is strongly coupled to the particular hardware of a computer system and thus the most difficult to change but also among the most stable with respect to consistency of interface. The progression from levels of &quot;hardness&quot; to &quot;softness&quot; in computer systems parallels a progression of layers of abstraction in computing.\r\nHardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware components.\r\nThe template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers, a control unit containing an instruction register and program counter, a memory to store both data and instructions, external mass storage, and input and output mechanisms. The meaning of the term has evolved to mean a stored-program computer in which an instruction fetch and a data operation cannot occur at the same time because they share a common bus. This is referred to as the Von Neumann bottleneck and often limits the performance of the system.","materialsDescription":" <span style=\"font-weight: bold; \">What does Hardware (H/W) mean?</span>\r\nHardware (H/W), in the context of technology, refers to the physical elements that make up a computer or electronic system and everything else involved that is physically tangible. This includes the monitor, hard drive, memory and CPU. Hardware works hand-in-hand with firmware and software to make a computer function.\r\n<span style=\"font-weight: bold; \">What are the types of computer systems?</span>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Personal computer</span></span>\r\nThe personal computer, also known as the PC, is one of the most common types of computer due to its versatility and relatively low price. Laptops are generally very similar, although they may use lower-power or reduced size components, thus lower performance.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Case</span></span>\r\nThe computer case encloses and holds most of the components of the system. It provides mechanical support and protection for internal elements such as the motherboard, disk drives, and power supplies, and controls and directs the flow of cooling air over internal components. The case is also part of the system to control electromagnetic interference radiated by the computer, and protects internal parts from electrostatic discharge. Large tower cases provide extra internal space for multiple disk drives or other peripherals and usually stand on the floor, while desktop cases provide less expansion room. All-in-one style designs include a video display built into the same case. Portable and laptop computers require cases that provide impact protection for the unit. A current development in laptop computers is a detachable keyboard, which allows the system to be configured as a touch-screen tablet. Hobbyists may decorate the cases with colored lights, paint, or other features, in an activity called case modding.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Power supply</span></span>\r\nA power supply unit (PSU) converts alternating current (AC) electric power to low-voltage direct current (DC) power for the internal components of the computer. Laptops are capable of running from a built-in battery, normally for a period of hours. The PSU typically uses a switched-mode power supply (SMPS), with power MOSFETs (power metal–oxide–semiconductor field-effect transistors) used in the converters and regulator circuits of the SMPS.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Motherboard</span></span>\r\nThe motherboard is the main component of a computer. It is a board with integrated circuitry that connects the other parts of the computer including the CPU, the RAM, the disk drives (CD, DVD, hard disk, or any others) as well as any peripherals connected via the ports or the expansion slots. The integrated circuit (IC) chips in a computer typically contain billions of tiny metal–oxide–semiconductor field-effect transistors (MOSFETs).\r\nComponents directly attached to or to part of the motherboard include:\r\n<ul><li><span style=\"font-weight: bold; \">The CPU (central processing unit)</span>, which performs most of the calculations which enable a computer to function, and is referred to as the brain of the computer which get a hold of program instruction from random-access memory (RAM), interprets and processes it and then send it backs to computer result so that the relevant components can carry out the instructions. The CPU is a microprocessor, which is fabricated on a metal–oxide–semiconductor (MOS) integrated circuit (IC) chip. It is usually cooled by a heat sink and fan, or water-cooling system. Most newer CPU include an on-die graphics processing unit (GPU). The clock speed of CPU governs how fast it executes instructions, and is measured in GHz; typical values lie between 1 GHz and 5 GHz. Many modern computers have the option to overclock the CPU which enhances performance at the expense of greater thermal output and thus a need for improved cooling.</li><li><span style=\"font-weight: bold; \">The chipset</span>, which includes the north bridge, mediates communication between the CPU and the other components of the system, including main memory; as well as south bridge, which is connected to the north bridge, and supports auxiliary interfaces and buses; and, finally, a Super I/O chip, connected through the south bridge, which supports the slowest and most legacy components like serial ports, hardware monitoring and fan control.</li><li><span style=\"font-weight: bold; \">Random-access memory (RAM)</span>, which stores the code and data that are being actively accessed by the CPU. For example, when a web browser is opened on the computer it takes up memory; this is stored in the RAM until the web browser is closed. It is typically a type of dynamic RAM (DRAM), such as synchronous DRAM (SDRAM), where MOS memory chips store data on memory cells consisting of MOSFETs and MOS capacitors. RAM usually comes on dual in-line memory modules (DIMMs) in the sizes of 2GB, 4GB, and 8GB, but can be much larger.</li><li><span style=\"font-weight: bold; \">Read-only memory (ROM)</span>, which stores the BIOS that runs when the computer is powered on or otherwise begins execution, a process known as Bootstrapping, or &quot;booting&quot; or &quot;booting up&quot;. The ROM is typically a nonvolatile BIOS memory chip, which stores data on floating-gate MOSFET memory cells.</li><li><span style=\"font-weight: bold; \">The BIOS (Basic Input Output System)</span> includes boot firmware and power management firmware. Newer motherboards use Unified Extensible Firmware Interface (UEFI) instead of BIOS.</li><li><span style=\"font-weight: bold; \">Buses</span> that connect the CPU to various internal components and to expand cards for graphics and sound.</li><li><span style=\"font-weight: bold; \">The CMOS</span> (complementary MOS) battery, which powers the CMOS memory for date and time in the BIOS chip. This battery is generally a watch battery.</li><li><span style=\"font-weight: bold; \">The video card</span> (also known as the graphics card), which processes computer graphics. More powerful graphics cards are better suited to handle strenuous tasks, such as playing intensive video games or running computer graphics software. A video card contains a graphics processing unit (GPU) and video memory (typically a type of SDRAM), both fabricated on MOS integrated circuit (MOS IC) chips.</li><li><span style=\"font-weight: bold; \">Power MOSFETs</span> make up the voltage regulator module (VRM), which controls how much voltage other hardware components receive.</li></ul>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Expansion cards</span></span>\r\nAn expansion card in computing is a printed circuit board that can be inserted into an expansion slot of a computer motherboard or backplane to add functionality to a computer system via the expansion bus. Expansion cards can be used to obtain or expand on features not offered by the motherboard.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Storage devices</span></span>\r\nA storage device is any computing hardware and digital media that is used for storing, porting and extracting data files and objects. It can hold and store information both temporarily and permanently, and can be internal or external to a computer, server or any similar computing device. Data storage is a core function and fundamental component of computers.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Fixed media</span></span>\r\nData is stored by a computer using a variety of media. Hard disk drives (HDDs) are found in virtually all older computers, due to their high capacity and low cost, but solid-state drives (SSDs) are faster and more power efficient, although currently more expensive than hard drives in terms of dollar per gigabyte, so are often found in personal computers built post-2007. SSDs use flash memory, which stores data on MOS memory chips consisting of floating-gate MOSFET memory cells. Some systems may use a disk array controller for greater performance or reliability.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Removable media</span></span>\r\nTo transfer data between computers, an external flash memory device (such as a memory card or USB flash drive) or optical disc (such as a CD-ROM, DVD-ROM or BD-ROM) may be used. Their usefulness depends on being readable by other systems; the majority of machines have an optical disk drive (ODD), and virtually all have at least one Universal Serial Bus (USB) port.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Input and output peripherals</span></span>\r\nInput and output devices are typically housed externally to the main computer chassis. The following are either standard or very common to many computer systems.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Input</span></span>\r\nInput devices allow the user to enter information into the system, or control its operation. Most personal computers have a mouse and keyboard, but laptop systems typically use a touchpad instead of a mouse. Other input devices include webcams, microphones, joysticks, and image scanners.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Output device</span></span>\r\nOutput devices display information in a human readable form. Such devices could include printers, speakers, monitors or a Braille embosser.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Mainframe computer</span></span>\r\nA mainframe computer is a much larger computer that typically fills a room and may cost many hundreds or thousands of times as much as a personal computer. They are designed to perform large numbers of calculations for governments and large enterprises.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Departmental computing</span></span>\r\nIn the 1960s and 1970s, more and more departments started to use cheaper and dedicated systems for specific purposes like process control and laboratory automation.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Supercomputer</span></span>\r\nA supercomputer is superficially similar to a mainframe, but is instead intended for extremely demanding computational tasks. As of June 2018, the fastest supercomputer on the TOP500supercomputer list is the Summit, in the United States, with a LINPACK benchmarkscore of 122.3 PFLOPS Light, by around 29 PFLOPS.\r\nThe term supercomputer does not refer to a specific technology. Rather it indicates the fastest computations available at any given time. In mid 2011, the fastest supercomputers boasted speeds exceeding one petaflop, or 1 quadrillion (10^15 or 1,000 trillion) floating point operations per second. Supercomputers are fast but extremely costly, so they are generally used by large organizations to execute computationally demanding tasks involving large data sets. Supercomputers typically run military and scientific applications. Although costly, they are also being used for commercial applications where huge amounts of data must be analyzed. For example, large banks employ supercomputers to calculate the risks and returns of various investment strategies, and healthcare organizations use them to analyze giant databases of patient data to determine optimal treatments for various diseases and problems incurring to the country.

Because of this, various network security technologies have been developed to protect organizational data and infrastructures. One of the most effective of these modern technologies is the data diode. Although it is one of the most effective network security tools available, you may not have heard of this technology and know little of what it does. Below, you'll find a description of what data diode technology is and how it works.\r\n<span style=\"font-weight: bold;\">What Is Data Diode Technology?</span>\r\nA data diode is a communication device that enables the safe, one-way transfer of data between segmented networks. Intelligent data diode design maintains physical and electrical separation of source and destination networks, establishing a non-routable, completely closed one-way data transfer protocol between networks. Intelligent data diodes effectively eliminate external points of entry to the sending system, preventing intruders and contagious elements from infiltrating the network. Securing all of a network’s data outflow with data diodes makes it impossible for an insecure or hostile network to pass along malware, access your system, or accidentally make harmful changes.\r\nData diodes allow companies to send process data in real time to information management systems for use in financial, customer service, and management decisions — without compromising the security of your network. This protects valuable information and network infrastructure from theft, destruction, tampering, and human error, mitigating the potential loss of thousands of dollars and countless hours of work.\r\n<span style=\"font-weight: bold;\">How Does Data Diode Technology Work?</span>\r\nA &quot;diode&quot; is an electronic component that only allows current to flow in one direction. Similarly, data diode technology lets information flow safely in only one direction, from secure areas to less secure systems, without permitting reverse access. A data diode also creates a physical barrier or “air gap” between the two points. This one-way connection prevents data leakage, eliminates the threat of malware, and fully protects the process control network. Moreover, a single data diode can handle data transfers from multiple servers or devices simultaneously, without bottlenecking.\r\n<span style=\"font-weight: bold;\">Where is it used?</span>\r\nIt’s typically used to guarantee information security or protection of critical digital systems, such as industrial control systems, from cyber attacks. While the use of these devices is common in high-security environments such as defense, where they serve as connections between two or more networks of differing security classifications, the technology is also being used to enforce one-way communications outbound from critical digital systems to untrusted networks connected to the Internet.\r\nThe physical nature of unidirectional networks only allows data to pass from one side of a network connection to another, and not the other way around. This can be from the &quot;low side&quot; or untrusted network to the &quot;high side&quot; or trusted network or vice versa. In the first case, data in the high side network is kept confidential and users retain access to data from the low side. Such functionality can be attractive if sensitive data is stored on a network which requires connectivity with the Internet: the high side can receive Internet data from the low side, but no data on the high side is accessible to Internet-based intrusion. In the second case, a safety-critical physical system can be made accessible for online monitoring, yet be insulated from all Internet-based attacks that might seek to cause physical damage. In both cases, the connection remains unidirectional even if both the low and the high network are compromised, as the security guarantees are physical in nature.\r\nThere are two general models for using unidirectional network connections. In the classical model, the purpose of the data diode is to prevent the export of classified data from a secure machine while allowing the import of data from an insecure machine. In the alternative model, the diode is used to allow export of data from a protected machine while preventing attacks on that machine.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Data_Diode.png"},{"id":532,"title":"Software","alias":"software","description":" Computer software, or simply software, is a collection of data or computer instructions that tell the computer how to work. This is in contrast to physical hardware, from which the system is built and actually performs the work. In computer science and software engineering, computer software is all information processed by computer systems, programs, and data. Computer software includes computer programs, libraries and related non-executable data, such as online documentation or digital media. Computer hardware and software require each other and neither can be realistically used on its own.\r\nAt the lowest programming level, executable code consists of machine language instructions supported by an individual processor — typically a central processing unit (CPU) or a graphics processing unit (GPU). A machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes that should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed to &quot;jump&quot; to a different instruction, or is interrupted by the operating system. As of 2015, most personal computers, smartphone devices, and servers have processors with multiple execution units or multiple processors performing computation together, and computing has become a much more concurrent activity than in the past.\r\nThe majority of software is written in high-level programming languages. They are easier and more efficient for programmers because they are closer to natural languages than machine languages. High-level languages are translated into machine language using a compiler or an interpreter or a combination of the two. Software may also be written in a low-level assembly language, which has strong correspondence to the computer's machine language instructions and is translated into machine language using an assembler.","materialsDescription":" <span style=\"font-weight: bold; \">What is software?</span>\r\nSometimes abbreviated as SW and S/W, software is a collection of instructions that enable the user to interact with a computer, its hardware, or perform tasks.

Two fundamental types of data access exist:\r\n<ol><li>sequential access (as in magnetic tape, for example)</li><li>random access (as in indexed media)</li></ol>\r\nData access crucially involves authorization to access different data repositories. Data access can help distinguish the abilities of administrators and users. For example, administrators may have the ability to remove, edit and add data, while general users may not even have &quot;read&quot; rights if they lack access to particular information.\r\nHistorically, each repository (including each different database, file system, etc.), might require the use of different methods and languages, and many of these repositories stored their content in different and incompatible formats.\r\nOver the years standardized languages, methods, and formats, have developed to serve as interfaces between the often proprietary, and always idiosyncratic, specific languages and methods. Such standards include SQL (1974- ), ODBC (ca 1990- ), JDBC, XQJ, ADO.NET, XML, XQuery, XPath (1999- ), and Web Services.\r\nSome of these standards enable translation of data from unstructured (such as HTML or free-text files) to structured (such as XML or SQL).\r\nStructures such as connection strings and DBURLs[1] can attempt to standardise methods of connecting to databases.\r\n<span style=\"font-weight: bold; \">A program for data analysis</span>\r\nA data analysis program is a specially developed software that can analyze any information. This is usually a database program. It is within the database that you can store any information in any amount. A functional program allows incoming and stored data to analyze. Software development can be done for any tasks, which means that the program for data analysis can be customized for any activity. If, for example, you have a trade organization, then your data analysis program will analyze products, customers, funds, product balance, and more.\r\n<span style=\"font-weight: bold;\">On-demand software delivery</span>\r\nA type of software delivery service where the software is provided to the customer through a network (such as the Internet) as a service. On-demand software delivery is also called software on-demand. The terms on-demand software and Software as a Service (SaaS) are often used interchangeably.\r\nData access, analysis and delivery software are end-user oriented tools for ad hoc data access, analysis and reporting as well as production reporting.&nbsp; These products are most commonly used by information consumers or power users rather than professional programmers.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Data_Access__Analysis__and_Delivery_Software1.png"},{"id":59,"title":"SCADA - Supervisory Control And Data Acquisition","alias":"scada-supervisory-control-and-data-acquisition","description":"<span style=\"font-weight: bold; \">SCADA</span> stands for <span style=\"font-weight: bold; \">Supervisory Control and Data Acquisition</span>, a term which describes the basic functions of a SCADA system. Companies use SCADA systems to control equipment across their sites and to collect and record data about their operations. SCADA is not a specific technology, but a type of application. Any application that gets operating data about a system in order to control and optimise that system is a SCADA application. That application may be a petrochemical distillation process, a water filtration system, a pipeline compressor, or just about anything else.\r\nSCADA solutions typically come in a combination of software and hardware elements, such as&nbsp;programmable logic controllers (PLCs) and remote terminal units (RTUs). Data acquisition in SCADA starts with PLCs and RTUs, which communicate with plant floor equipment such as factory machinery and sensors. Data gathered from the equipment is then sent to the next level, such as a control room, where operators can supervise the PLC and RTU controls using human-machine interfaces (HMIs). HMIs are an important element of SCADA systems. They are the screens that&nbsp;operators&nbsp;use to communicate with the SCADA system.\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">The major components of a SCADA technology include:</span></p>\r\n<ul><li><span style=\"font-weight: bold;\">Master Terminal Unit (MTU).</span> It comprises a computer, PLC and a network server that helps MTU to communicate with the RTUs. MTU begins communication, collects and saves data, helps to interface with operators and to communicate data to other systems.</li><li><span style=\"font-weight: bold;\">Remote Terminal Unit (RTU).</span> RTU is used to collect information from these sensors and further sends the data to MTU. RTUs have the storage capacity facility. So, it stores the data and transmits the data when MTU sends the corresponding command.</li><li><span style=\"font-weight: bold;\">Communication Network (defined by its network topology).</span> In general, network means connection. When you tell a SCADA communication network, it is defined as a link between RTU in the field to MTU in the central location. The bidirectional wired or wireless communication channel is used for the networking purpose. Various other communication mediums like fiber optic cables, twisted pair cables, etc. are also used.</li></ul>\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">Objectives of Supervisory Control and Data Acquisition system</span></p>\r\n<ul><li><span style=\"font-weight: bold;\">Monitor:</span> SCADA control system continuously monitors the physical parameters</li><li><span style=\"font-weight: bold;\">Measure:</span> It measures the parameter for processing</li><li><span style=\"font-weight: bold;\">Data Acquisition:</span> It acquires data from RTU, data loggers, etc</li><li><span style=\"font-weight: bold;\">Data Communication:</span> It helps to communicate and transmit a large amount of data between MTU and RTU units</li><li><span style=\"font-weight: bold;\">Controlling:</span> Online real-time monitoring and controlling of the process</li><li><span style=\"font-weight: bold;\">Automation:</span> It helps for automatic transmission and functionality</li></ul>\r\n\r\n","materialsDescription":"<h1 class=\"align-center\">Who Uses SCADA?</h1>\r\nSCADA systems are used by industrial organizations and companies in the public and private sectors to control and maintain efficiency, distribute data for smarter decisions, and communicate system issues to help mitigate downtime. Supervisory control systems work well in many different types of enterprises because they can range from simple configurations to large, complex installations. They are the backbone of many modern industries, including:\r\n<ul><li>Energy</li><li>Food and beverage</li><li>Manufacturing</li><li>Oil and gas</li><li>Power</li><li>Recycling</li><li>Transportation</li><li>Water and waste water</li><li>And many more</li></ul>\r\nVirtually anywhere you look in today's world, there is some type of SCADA monitoring system running behind the scenes: maintaining the refrigeration systems at the local supermarket, ensuring production and safety at a refinery, achieving quality standards at a waste water treatment plant, or even tracking your energy use at home, to give a few examples. Effective SCADA systems can result in significant savings of time and money. Numerous case studies have been published highlighting the benefits and savings of using a modern SCADA software.\r\n<h1 class=\"align-center\">Benefits of using SCADA software</h1>\r\nUsing modern SCADA software provides numerous benefits to businesses, and helps companies make the most of those benefits. Some of these advantages include:\r\n<span style=\"font-weight: bold; \">Easier engineering:</span> An advanced supervisory control application such provides easy-to-locate tools, wizards, graphic templates and other pre-configured elements, so engineers can create automation projects and set parameters quickly, even if they don't have programming experience. In addition, you can also easily maintain and expand existing applications as needed. The ability to automate the engineering process allows users, particularly system integrators and original equipment manufacturers (OEM), to set up complex projects much more efficiently and accurately.\r\n<span style=\"font-weight: bold; \">Improved data management:</span> A high-quality SCADA system makes it easier to collect, manage, access and analyze your operational data. It can enable automatic data recording and provide a central location for data storage. Additionally, it can transfer data to other systems such as MES and ERP as needed. \r\n<span style=\"font-weight: bold; \">Greater visibility:</span> One of the main advantages of using SCADA software is the improvement in visibility into your operations. It provides you with real-time information about your operations and enables you to conveniently view that information via an HMI. SCADA monitoring can also help in generating reports and analyzing data.\r\n<span style=\"font-weight: bold; \">Enhanced efficiency:</span> A SCADA system allows you to streamline processes through automated actions and user-friendly tools. The data that SCADA provides allows you to uncover opportunities for improving the efficiency of the operations, which can be used to make long-term changes to processes or even respond to real-time changes in conditions.\r\n<span style=\"font-weight: bold; \">Increased usability:</span> SCADA systems enable workers to control equipment more quickly, easily and safely through an HMI. Rather than having to control each piece of machinery manually, workers can manage them remotely and often control many pieces of equipment from a single location. Managers, even those who are not currently on the floor, also gain this capability.\r\n<span style=\"font-weight: bold; \">Reduced downtime:</span> A SCADA system can detect faults at an early stage and push instant alerts to the responsible personnel. Powered by predictive analytics, a SCADA system can also inform you of a potential issue of the machinery before it fails and causes larger problems. These features can help improve the overall equipment effectiveness (OEE) and reduce the amount of time and cost on troubleshooting and maintenance.\r\n<span style=\"font-weight: bold;\">Easy integration:</span> Connectivity to existing machine environments is key to removing data silos and maximizing productivity. \r\n<span style=\"font-weight: bold;\">Unified platform:</span>All of your data is also available in one platform, which helps you to get a clear overview of your operations and take full advantage of your data. All users also get real-time updates locally or remotely, ensuring everyone on your team is on the same page.<br /><br />","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/SCADA__-_Supervisory_Control_And_Data_Acquisition.png"},{"id":840,"title":"ICS/SCADA Cyber Security","alias":"icsscada-cyber-security","description":"SCADA security is the practice of protecting supervisory control and data acquisition (SCADA) networks, a common framework of control systems used in industrial operations. These networks are responsible for providing automated control and remote human management of essential commodities and services such as water, natural gas, electricity and transportation to millions of people. They can also be used to improve the efficiencies and quality in other less essential (but some would say very important!) real-world processes such as snowmaking for ski resorts and beer brewing. SCADA is one of the most common types of industrial control systems (ICS).\r\nThese networks, just like any other network, are under threat from cyber-attacks that could bring down any part of the nation's critical infrastructure quickly and with dire consequences if the right security is not in place. Capital expenditure is another key concern; SCADA systems can cost an organization from tens of thousands to millions of dollars. For these reasons, it is essential that organizations implement robust SCADA security measures to protect their infrastructure and the millions of people that would be affected by the disruption caused by an external attack or internal error.\r\nSCADA security has evolved dramatically in recent years. Before computers, the only way to monitor a SCADA network was to deploy several people to each station to report back on the state of each system. In busier stations, technicians were stationed permanently to manually operate the network and communicate over telephone wires.\r\nIt wasn't until the introduction of the local area network (LAN) and improvements in system miniaturization that we started to see advances in SCADA development such as the distributed SCADA network. Next came networked systems that were able to communicate over a wide area network (WAN) and connect many more components together.\r\nFrom local companies to federal governments, every business or organization that works with SCADA systems are vulnerable to SCADA security threats. These threats can have wide-reaching effects on both the economy and the community. Specific threats to SCADA networks include the following:\r\n<span style=\"font-weight: bold;\">Hackers.</span> Individuals or groups with malicious intent could bring a SCADA network to its knees. By gaining access to key SCADA components, hackers could unleash chaos on an organization that can range from a disruption in services to cyber warfare.\r\n<span style=\"font-weight: bold;\">Malware.</span> Malware, including viruses, spyware and ransomware can pose a risk to SCADA systems. While malware may not be able to specifically target the network itself, it can still pose a threat to the key infrastructure that helps to manage the SCADA network. This includes mobile SCADA applications that are used to monitor and manage SCADA systems.\r\n<span style=\"font-weight: bold;\">Terrorists.</span> Where hackers are usually motivated by sordid gain, terrorists are driven by the desire to cause as much mayhem and damage as possible.\r\n<span style=\"font-weight: bold;\">Employees.</span> Insider threats can be just as damaging as external threats. From human error to a disgruntled employee or contractor, it is essential that SCADA security addresses these risks.\r\nManaging today's SCADA networks can be a challenge without the right security precautions in place. Many networks are still without the necessary detection and monitoring systems and this leaves them vulnerable to attack. Because SCADA network attacks exploit both cyber and physical vulnerabilities, it is critical to align cybersecurity measures accordingly.","materialsDescription":"<span style=\"font-weight: bold;\">What is the difference between ICS/SCADA cybersecurity and information security?</span>\r\nAutomated process control systems (SCADA) have a lot of differences from “traditional” corporate information systems: from the destination, specific data transfer protocols and equipment used and ending with the environment in which they operate. In corporate networks and systems, as a rule, the main protected resource is information that is processed, transmitted and stored in automated systems, and the main goal is to ensure its confidentiality. In ICS, the protected resource, first of all, is the technological process itself, and the main goal is to ensure its continuity (accessibility of all nodes) and integrity (including information transmitted between the nodes of the ICS). Moreover, the field of potential risks and threats to ICS, in comparison with corporate systems, expands with risks of potential damage to life and health of personnel and the public, damage to the environment and infrastructure. That is why it is incorrect to talk about “information security” in relation to ICS/SCADA. In English sources, the term “cybersecurity” is used for this, a direct translation of which (cybersecurity) is increasingly found in our market in relation to the protection of process control systems.\r\n<span style=\"font-weight: bold;\">Is it really necessary?</span>\r\nIt is necessary. There are a number of myths about process control systems, for example: “process control systems are completely isolated from the outside world”, “process control systems are too specific for someone to crack”, “process control systems are reliably protected by the developer”, or even “No one will ever try us, hacking us is not interesting. ” All this is no longer true. Many modern distributed process control systems have one or another connection with the corporate network, even if the system owners are unaware of this. Communication with the outside world greatly simplifies the task of the attacker, but does not remain the only possible option. Automated process control software and data transfer protocols are, as a rule, very, very insecure against cyber threats. This is evidenced by numerous articles and reports of experts involved in the study of the protection of industrial control systems and penetration tests. The PHDays III section on hacking automated process control systems impressed even ardent skeptics. Well, and, of course, the argument “they have NOT attacked us, therefore they will not” - can hardly be considered seriously. Everyone has heard about Stuxnet, which dispelled almost all the myths about the safety of ICS at once.\r\n<span style=\"font-weight: bold;\">Who needs this?</span>\r\nWith the phrase ICS/SCADA, most imagine huge plants, automated CNC machines or something similar. However, the application of process control systems is not limited to these objects - in the modern age of automation, process control systems are used everywhere: from large production facilities, the oil and gas industry, transport management to smart home systems. And, by the way, with the protection of the latter, as a rule, everything can be much worse, because the developer silently and imperceptibly shifts responsibility to the shoulders of the user.\r\nOf course, some of the objects with automated process control systems are more interesting for attackers, others less. But, given the ever-growing number of vulnerabilities discovered and published in the ICS, the spread of &quot;exclusive&quot; (written for specific protocols and ICS software) malware, considering your system safe &quot;by default&quot; is unreasonable.\r\n<span style=\"font-weight: bold;\">Are ICS and SCADA the same thing?</span>\r\nNo. SCADA systems (supervisory control and data acquisition, supervisory control and data collection) are part of the control system. Usually, a SCADA system means centralized control and management systems with the participation of a person as a whole system or a complex of industrial control systems. SCADA is the central link between people (human-machine interfaces) and PLC levels (programmable logic controller) or RTU (remote terminal unit).\r\n<span style=\"font-weight: bold;\">What is ICS/SCADA cybersecurity?</span>\r\nIn fact, ICS cybersecurity is a process similar to “information security” in a number of properties, but very different in details. And the devil, as you know, lies in them. ICS/SCADA also has similar information security-related processes: asset inventory, risk analysis and assessment, threat analysis, security management, change management, incident response, continuity, etc. But these processes themselves are different.<br />The cyber security of ICSs has the same basic target qualities - confidentiality, integrity and accessibility, but the significance and point of application for them are completely different. It should be remembered that in ICS/SCADA we, first of all, protect the technological process. Beyond this - from the risks of damage to human health and life and the environment.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_SCADA_Cyber_Security.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":5513,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/siemens_SIRIUS_3RA6.jpg","logo":true,"scheme":false,"title":"Siemens SIRIUS 3RA6","vendorVerified":0,"rating":"0.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":1,"alias":"siemens-sirius-3ra6","companyTitle":"Siemens","companyTypes":["vendor"],"companyId":2795,"companyAlias":"siemens","description":"SIRIUS 3RA6 compact starters are universal motor feeders according to IEC 60947‑6‑2.

They combine the functions of a motor starter protector, a contactor and a solid-state overload relay in one enclosure. The 45-mm-wide direct-on-line starters and 90-mm-wide reversing starters are available as variants. \r\n<b>Applications </b>\r\nSIRIUS compact starters can be used wherever standard three-phase motors or resistive loads up to 32 A (approx. 15 kW/400 V) are directly started or switched. The compact starters are not suitable for the protection of DC loads. Approvals according to IEC, UL, CSA and CCC standards have been issued for the compact starters.\r\n<b>Very high operational reliability </b>\r\nThe high short-circuit breaking capacity and defined shut-down when the end of service life is reached means a very high level of operational reliability that would otherwise have only been possible with considerable additional outlay. This sets the SIRIUS compact starter apart from devices with similar functionality. \r\n<b>Safe disconnection </b>\r\nThe auxiliary switches (NC contacts) of the 3RA6 compact starters are designed as mirror contacts. This enables their use for safe disconnection - e.g. EMERGENCY-STOP up to SIL 1 (IEC 62061) or PL c (ISO 13849-1) or, if used in conjunction with an additional infeed contactor, up to SIL 3 (IEC 62061) or PL e (ISO 13849-1). \r\n<b>Permanent wiring/easy replacement </b>\r\nUsing the SIRIUS infeed system for 3RA6 it is possible to carry out the wiring in advance without a compact starter needing to be connected. A compact starter is very easily replaced simply by pulling it out of the device without disconnecting the wiring.

Product life management concepts were first introduced where safety and control have been extremely important, notably the aerospace, medical device, military and nuclear industries. These industries originated the discipline of configuration management (CM), which evolved into electronic data management systems (EDMS), which then further evolved to product data management (PDM).\r\nOver the last ten years, manufacturers of instrumentation, industrial machinery, consumer electronics, packaged goods and other complex engineered products have discovered the benefits of PLM management and are adopting efficient PLM software in increasing numbers.\r\n<p class=\"align-center\"><span style=\"font-weight: bold;\">The PLM Stages</span></p>\r\n<span style=\"font-weight: bold; \">Beginning of Life (BOL):</span> The beginning of life phase includes all of the design and manufacturing, which consists of the initial conceptualization and development, and any prototypes built. Initial development has multiple sub-actions that identify all the requirements, concepts, and necessary testing. \r\n<span style=\"font-weight: bold; \">Middle of Life (MOL):</span> The middle of life phase is post-manufacturing, when your product is distributed, used, and serviced. At this point, your product is in the hands of the end user. You can collect data on any failures, maintenance rates, and user experience to get information for immediate fixes and future development.\r\n<span style=\"font-weight: bold; \">End of Life (EOL):</span> The end of life phase is the retiring, recycling, or disposing of your product. At this point, the reverse logistics happen for the company. EOL starts when users no longer have a need for the product. At this stage, companies collect information about what parts and materials are still valuable.\r\n<span style=\"font-weight: bold;\">Product lifecycle management software</span> is used to deliver all kinds of products to market, which means there are a lot of different providers out there. Its purpose today is to help organizations: \r\n<ol><li>Develop new products using CAD software</li><li>Produce and manufacture new products</li><li>Bring those products to market</li></ol>\r\nAnd increasingly, product life management software has to process the feedback from the market back to the design and production processes. To achieve these goals, product lifecycle management solutions have to do four things:\r\n<ul><li>Link together CAD metadata with a bill of materials</li><li>Manage workflows for organizations needed to bring products to market</li><li>Manage product data as they move through the product development lifecycle stages</li><li> Hook in auxiliary suppliers and business stakeholders to a shared version of truth or single source of truth.</li></ul>\r\n\r\n","materialsDescription":"<h1 class=\"align-center\">Top PLM System Software Requirements</h1>\r\n<span style=\"font-weight: bold; \">Bill of Materials.</span> Having a common source of information across your company is incredibly important during product development. That’s why a bill of materials (BOM) is key to include in your list of product lifecycle management requirements. At the very least, your system should provide a single definition of a particular product and its components. More advanced options include features specifically designed for different team members such as designers, engineers and other professionals who frequently&nbsp; collaborate.\r\n<span style=\"font-weight: bold; \">Computer-Aided Design Management.</span> Managing your CAD activities and documents is more than useful when it comes to PLM. Your solution should be able to manage changes to product configurations while maintaining the functional and physical attributes of a product throughout its lifecycle. Production engineering changes should proliferate throughout your processes, with the changes evident in the subsequent BOMs and plans.\r\n<span style=\"font-weight: bold; \">Manufacturing Product Management.</span> During a product’s lifecycle, you want to keep an eye on your portfolio. With portfolio management, users can determine the proper investment balance to maximize their research and development investment returns. Some systems provide strategy tools to spotlight priorities and support planning. Top PLM software can even determine the best possible investment scenario. Users can also track project progress to completion, which is automatically documented in the product record. This allows greater insight into your processes, facilitating better resource management and allocation.\r\n<span style=\"font-weight: bold; \">Product Regulation and Governance.</span> Failing to follow regulation and compliance standards is one of the quickest ways to earn your business a bad reputation. But having the right tools built into your product life management system can make staying compliant much easier than it would be otherwise. Your solution should be able to centralize relevant information and documentation, making it easier for enterprise organizations to achieve and maintain compliance.&nbsp; You also may choose a system that can comply with medical, environmental, safety, FSA and ISO standards depending on your industry.\r\n<span style=\"font-weight: bold; \">Project and Component Maintenance.</span> Project management tools are vital for providing users visibility into daily processes and progress. These features include tracking and scheduling capabilities, which enable you to manage product development along with resource allocation in real time. Users can also see upcoming milestones and constraints for further planning.\r\n<span style=\"font-weight: bold; \">Quote Process Management.</span> Data from many different sources is often needed during the quote process. PLM’s inherent coordination capabilities gather and organize data pertaining to product design to support your engineering teams. This includes teams developing engineer-to-order and configure-to-order products. The system only shares the necessary data, meaning your team members can spend more time focusing on their work and less on hunting down information. \r\n<span style=\"font-weight: bold; \">Risk Management. </span>This feature brings risks to users’ attention, allowing them to manage, report and mitigate those instabilities. Reducing risks early on prevents issues from growing as they move through product development unseen, reducing the overall cost of development. Some systems do this by “detecting” or “highlighting” risks, whereas some systems simply offer full visibility through PM tools.\r\n<span style=\"font-weight: bold;\">Workflow and Change Management.</span> Plainly said, this suite of PLM software tools gives users insight into product activities. Users can determine phases for a project, as well as assign milestones to keep projects on track. Some systems allow users to see all pending and implemented changes, as well as all items that endure the subsequent effects. This visibility extends to portfolio and resource management, also.\r\n\r\n","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/PLM_-_Product_Lifecycle_Management.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]}],"suppliedProducts":[],"partnershipProgramme":{"levels":[{"id":493,"level":"References Solution Partner"},{"id":495,"level":"Approved Partner"},{"id":497,"level":"Solution partner"}],"partnerDiscounts":{"References Solution Partner":"","Approved Partner":"","Solution partner":""},"registeredDiscounts":{"References Solution Partner":"","Approved Partner":"","Solution partner":""},"additionalBenefits":[],"salesPlan":{"References Solution Partner":"","Approved Partner":"","Solution partner":""},"additionalRequirements":[]}}},"aliases":{},"links":{},"meta":{},"loading":false,"error":null},"implementations":{"implementationsByAlias":{},"aliases":{},"links":{},"meta":{},"loading":false,"error":null},"agreements":{"agreementById":{},"ids":{},"links":{},"meta":{},"loading":false,"error":null},"comparison":{"loading":false,"error":false,"templatesById":{},"comparisonByTemplateId":{},"products":[],"selectedTemplateId":null},"presentation":{"type":null,"company":{},"products":[],"partners":[],"formData":{},"dataLoading":false,"dataError":false,"loading":false,"error":false},"catalogsGlobal":{"subMenuItemTitle":""}}
