Configuration Management (CM) is a crucial discipline within IT Service Management (ITSM) that focuses on establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life. It involves identifying, controlling, and verifying all configuration items (CIs) that make up an IT environment, including hardware, software, documentation, and processes. A Configuration Management Database (CMDB) is often central to this process, serving as a repository for CI data and their interrelationships. Effective CM enables accurate impact analysis, change control, incident resolution, and asset management, thereby supporting ITIL best practices and ensuring the integrity of IT services.
Configuration Management is the practice of systematically identifying, documenting, controlling, and verifying all components (configuration items) of an IT service or system, along with their interrelationships, to ensure consistency and support lifecycle management.
