CIs can include source code files, documents, scripts, and any other components that make up the software system. By clearly identifying these items, SCM ensures that all changes are tracked and managed systematically.

The second core principle is control, which involves managing and controlling changes to the identified configuration items. This includes establishing change control processes and procedures to ensure that all modifications are authorized, documented, and implemented consistently. By controlling changes, SCM helps prevent unauthorized modifications and ensures that the software system remains stable and reliable.

Status accounting is another fundamental concept of SCM, which involves maintaining accurate records of the status and history of configuration items. This includes tracking changes, documenting the reasons for each change, and maintaining a clear audit trail. Status accounting provides a comprehensive view of the project's evolution, enabling teams to track progress, identify potential issues, and make informed decisions.

Finally, audits and reviews are essential components of SCM, ensuring that the configuration management processes are followed correctly and that the software system meets the required standards and specifications. Regular audits and reviews help identify discrepancies, validate changes, and ensure that the software system is aligned with project goals.

In summary, the fundamental concepts of SCM—identification, control, status accounting, and audits—are critical for maintaining the integrity and traceability of software projects. By adhering to these principles, development teams can effectively manage changes, ensure software quality, and achieve project success.
