Whether you work in big or small organizations, safeguarding and maintaining data is always important and it keeps track of a fair amount for you, it is just a matter of extracting the data. Some of the data is included in the system by you or any other developer when you fill in the commit message with proper information; for instance, details of the bug you are fixing from the bug tracking system.

The data is not only valid for management, but can also be used to add more time to refactor the .c files, where almost all bugs are fixed.
