Question 1 of 30

How would you define software configuration management?

In simple terms, software configuration management is the process of systematically managing, tracking, and controlling the 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 that all changes made to the software system are consistent with Amazon development practices and internal methodologies. The ultimate goal is productivity improvement with minimal mistakes throughout the development lifecycle. Here, the interviewer is looking for how you prioritize configuration management duties and responsibilities and your experience with controlling something even if you don't know what it is. Configuration management is used when multiple team members are working on software or a revision that is running on multiple machines or needs constant updating. It may also be necessary if a company has multiple locations or divisions that need to distribute work concurrently.
