In simple terms, software configuration management systematically manages, tracks, and controls changes that happen in the software development lifecycle. This includes changes in the code, documentation, and process. Change control, however unpopular, is a function that ensures all changes made to the software system are consistent with Microsoft development practices and internal methodologies. The ultimate goal is to see productivity improvement with a minimal amount of mistakes throughout the development lifecycle. Here, the interviewer is looking for how you prioritize configuration management duties and responsibilities and your experience controlling something even if you don't know what it is. This can be tricky, so let me explain. Configuration management is used if multiple team members are working on a software or revision running on multiple machines or needs constant updating. Another reason is if a company has multiple locations or divisions that need to distribute work concurrently.
