What is Configuration Management
Configuration Management (CM) is a set of processes and tools used to systematically manage, control, and track changes to an information system’s components and associated documentation throughout its lifecycle. The goal of configuration management is to ensure that a system functions as intended and that any changes made to it are well-documented, controlled, and traceable.
Key Aspects of Configuration Management
- Configuration Identification: Involves identifying and labeling all the components of a system, including hardware, software, documentation, and any other relevant items. Each configuration item (CI) is uniquely identified and tracked.
- Configuration Control: Ensures that changes to a system are evaluated, approved, and implemented in a controlled manner to prevent unauthorized or unapproved changes.
- Configuration Status Accounting: Involves maintaining and documenting the current status of each configuration item throughout its lifecycle, providing a record of changes and approval status.
- Configuration Audits: Periodic reviews or audits to ensure that the actual configuration of the system matches its documented configuration.
- Configuration Baseline: A set of specifications and documentation representing a known, stable configuration of a system at a specific point in time.
- Change Management: The process of requesting, evaluating, approving, and implementing changes to a system, ensuring they are well-documented and tested.
Configuration management is particularly important in complex systems, such as software development, where multiple components need to work together cohesively. It helps organizations maintain consistency, reliability, and control over their systems, reducing the risk of errors and enhancing overall quality throughout the system’s lifecycle. Configuration management practices are applied in various industries, including software development, aerospace, telecommunications, and more.
