Configuration Control: includes the evaluation of all change-requests and change-proposals, and their subsequent approval or disapproval. Traditionally, the configuration management system is an umbrella system that encompasses many other small essential systems such as the change control system. Configuration management tools enable changes and deployments to be faster, repeatable, scalable, predictable, and able to maintain the desired state, which brings controlled assets into an expected state. Example: Suppose your company creates an avionics system that includes an LCD screen from a third-party company. I get a number of questions about the differences between a Configuration Management System and a Change Management System.This question arises because most project managers have heard about a Change Management System, and Change Control, but most of them haven’t seen, heard or used a Configuration Management System. During system development, CM allows program management to track requirements throughout the life-cycle through acceptance and operations and maintenance. A complete CM program includes provisions for the storing, tracking, and updating of all system information on a component, subsystem, and system basis.[6]. It is sometimes referred to as IT automation. Follow TOOLSQA for latest updates on QA Events and Tutorials. Outside the military, the CM process is also used with IT service management as defined by ITIL, and with other domain models in the civil engineering and other industrial engineering segments such as roads, bridges, canals, dams, and buildings.[3][4][5].

For information assurance, CM can be defined as the management of security features and assurances through control of changes made to hardware, software, firmware, documentation, test, test fixtures, and test documentation throughout the life cycle of an information system. This reverse engineering process is wasteful in terms of human and other resources and can be minimized or eliminated using CM. The purpose of configuration management. The baseline for a project contains all of the technical requirements and related cost and schedule requirements that are sufficiently … CM implements the policies, procedures, techniques, and tools that manage, evaluate proposed changes, track the status of changes, and maintain an inventory of system and support documents as the system changes. The CM process became its own technical discipline sometime in the late 1960s when the DoD developed a series of military standards called the "480 series" (i.e., MIL-STD-480, MIL-STD-481 and MIL-STD-483) that were subsequently issued in the 1970s. Specifically, it aims to ensure that operations are not disrupted due to the asset (or parts of the asset) overrunning limits of planned lifespan or below quality levels. Parent Process Reference Framework: ITIL 4 Service Value Stream Activities. [8] Now widely adopted by numerous organizations and agencies, the CM discipline's concepts include systems engineering (SE), Integrated Logistics Support (ILS), Capability Maturity Model Integration (CMMI), ISO 9000, Prince2 project management method, COBIT, ITIL, product lifecycle management, and Application Lifecycle Management. The Configuration Management process establishes and maintains the consistency of a system’s functional, performance and physical attributes with its requirements, design and operational information and allows technical insight into all levels of the system design throughout the system’s life cycle. Complex assets such as aircraft, ships, industrial machinery etc. In practice, it may be that the configuration management system is part of the change control system. Understanding the "as is" state of an asset and its major components is an essential element in preventive maintenance as used in maintenance, repair, and overhaul and enterprise asset management systems. It helps to verify that proposed changes are systematically considered to minimize adverse effects. As changes inevitably occur in the requirements and design, they must be approved and documented, creating an accurate record of the system status. The consumers of this data have grown more numerous and complex with the growth of programs offered by original equipment manufacturers (OEMs). The CM process is widely used by military engineering organizations to manage changes throughout the system lifecycle of complex systems, such as weapon systems, military vehicles, and information systems. All components and sub-components are carefully itemized. This website uses cookies to improve your experience while you navigate through the website. Lower support costs due to a decrease in reactive support issues. Not only for project management and audit purposes, but for software development activities such as debugging (for example, knowing what has changed between one set of tests and the next to help identify what could b… Terraform. It helps to eliminate confusion, chaos, double maintenance and the shared data problem. Configuration management software integrates with version control systems, software testing products, bug tracking tools, and other software development tools. These changes came from the popularity of DevOps, increases in cloud computing, and new automation tooling. Empower user productivity by providing the right software at the right time. These include: 1. This website uses cookies to improve your experience. Understanding how near the end of their life each of these components is has been a major undertaking involving labor-intensive record keeping until recent developments in software. SCM practices include revision control and the establishment of baselines. Configuration status accounting is the ability to record and report on the configuration baselines associated with each configuration item at any moment of time. record of changes to documentation over time. The purpose of configuration identification is to maintain control of an evolving system by: Uniquely identifying the system, revisions of the system and the component parts of each revision ; Understanding the status of configuration items as they progress through the development process. CM help in accessing accurate historical record of system, which is very useful for project management and audit purposes. Maximize hardware and software investments. The IEEE 12207 process IEEE 12207.2 also has these activities and adds "Release management and delivery". Availability of accurate and timely data is essential in order for CM to provide operational value and a lack of this can often be a limiting factor. Configuration identification is the process of identifying the attributes that define every aspect of a configuration item. [11] Example systems include Ansible, Bcfg2, CFEngine, Chef, Otter, Puppet, Quattor, SaltStack, Terraform, d Vagrant. Configuration management verifies that changes are carried out as prescribed and that documentation of items and systems reflects their true configuration. But opting out of some of these cookies may have an effect on your browsing experience. This means there is a clear understanding of a product and its component elements and how they relate to each other. Developers and others involved in the project can use SCM to keep track of artifacts, including source code, documentation, problems, changes requested and changes made. I live in Amsterdam(NL), with my wife and a lovely daughter. It covers the process of controlling modifications to the system's design, hardware, firmware, software, and documentation. It is … Configuration Management (CM) is a systems engineering process for establishing and maintaining consistency of a product’s performance, functional, and physical attributes with its requirements, design, and operational information throughout its life. By Vinai Prakash. Configuration change control is a set of processes and approval stages required to change a configuration item's attributes and to re-baseline them. High-quality of the software that has been tested and used, makes it a reusable asset and saves development costs. Over the time, the specific LCD screen becomes obsolete and you need to find a suitable replacement to continue your production. Configuration management is intended to realize the following goals for IT projects, regardless of your ITSM framework: Defining, identifying, and understanding configuration dependencies between assets. Configuration audits verify that the system and subsystem configuration documentation complies with the functional and physical performance characteristics before acceptance into an architectural baseline. CM verifies that changes are carried out as prescribed and that documentation of items and systems reflects their true configuration. CI incrementally establishes and maintains the definitive current basis for Configuration Status Accounting (CSA) of a system and its. Establishing rigorous configuration control enables the successful deve… The CM process for both hardware- and software-configuration items comprises five distinct disciplines as established in the MIL–HDBK–61A[9] Changes to the system are proposed, evaluated, and implemented using a standardized and systematic approach. Use Configuration Manager to help you with the following systems management activities: 1. The CM policy would identify who in which organization is authorized to approve utilizing a different but compatible version of the original LCD screen. I’M LAKSHAY SHARMA AND I’M FULL STACK TEST AUTOMATION ENGINEER. The role was a lot of manual work involving carefully documenting the state of the system. .Maintains project team morale. Configuration management can be used to maintain OS configuration files. Labeling revisions to configuration items and baselines. The lack of CM, or its ineffective implementation can be very expensive and sometimes can lead to failure of equipment or loss of life. 2. The relatively minimal cost of implementing CM is returned manyfold in cost avoidance. CMDBs are used to track Configuration Items (CIs) and the dependencies between them, where CIs represent the things in an enterprise that are worth tracking and managing, such as but not limited to computers, software, software licenses, racks, network devices, storage, and even the components within such items. Software c… [17] There are construction-based configuration management tools that aim to document change orders and RFIs in order to ensure a project stays on schedule and on budget. These disciplines are carried out[by whom?] The SCM process further defines the need to trace changes, and the ability to verify that the final delivered software has all of the planned enhancements that are supposed to be included in the release. By knowing what has changed between one set of tests and the next, it helps to identify what could possibly be causing a fault. Puppet Configuration Tool. When requirements management was a simple matter of writing MS-Word documents, (or WordPerfect… remember that?)
