What is the purpose of a configuration item (CI)?

The purpose of a configuration item (CI) is fundamentally tied to configuration management, which involves systematically managing and organizing all elements of a system throughout its life cycle. A configuration item is a distinct entity that is designated for configuration management, enabling teams to keep track of the different components and their interrelationships.

By identifying a CI, projects can establish a clear understanding of what needs to be controlled and monitored within the system. This includes keeping records of the CI's development, modifications, and performance, ensuring integrity and traceability. Effective configuration management allows for better quality assurance, facilitates communication among team members, and helps in managing change, which is crucial throughout the project's life cycle.

Other options, while they deal with important aspects of project management, do not directly relate to the role of configuration items. Therefore, focusing on B helps to highlight the critical role of configuration management in systems engineering.
