Assume you have a large or mid-level organization where a repository is shared by multiple developers and they often push the code during a day. Let’s say, a developer was building a feature and was coding in a class/module that was being called by ten other places, coded by other developer(s). Let’s also assume that he has completed his feature, tested it and it’s ready for production and it is pushed to the repository and deployed. But he might not be aware of the fact that he has changed the code that was being called by several other modules, and now, let’s say if not all, 2 to 3 of the places are broken and no one knows about it until end-user hits the problem, report it, then the developers fix the code for those 2 to 3 places, this might end up causing problems in other places where it was being called, and you end up in total chaos and it also multiplies the cost of development.
