System engineering relies heavily on configuration management because it offers an organised method for handling the complexity of system development, deployment, and maintenance. It includes all of the procedures, instruments, and methods required to recognise, manage, and keep track of changes to the individual system parts and the relationships among them throughout the course of a system's lifespan. The core ideas and advantages of configuration management in system engineering are examined in this abstract. A system's configuration components, such as its hardware, software, documentation, and associated artefacts, must be consistently recognised, documented, and managed in order for configuration management to be effective. It creates a distinct baseline that identifies the system's starting condition and makes it easier to handle future modifications effectively. The creation of configuration baselines, version control, change control, and configuration audits are all part of configuration management tasks. The system's elements and their interactions are defined by configuration baselines. They serve as a starting point for future development and change management and capture the status of the system at a particular moment in time. The ability to identify and manage changes made to system components using version control systems ensures that various versions may be recognised and accessed as necessary. The review, approval, and implementation of proposed changes are governed by change control mechanisms, which make sure that any possible effects are fully considered before implementation. Systematic assessments of the system's components' documentation, control, and alignment with predetermined baselines are provided through configuration audits.
