I have an interesting, fairly common I guess, issue with one of the developers in my team. The guy is a great developer, work fast and productive, produces fairly good quality code and all. Good engineer. But there is a problem with him - very often he fails to address edge cases in his code.
We spoke with him about it many times and he is trying but I guess he just doesn't think this way. So what ends up happening is that QA would find plenty issues with his code and return it back for development again and again, ultimately resulting in missed deadlines and everyone in the team unhappy.
I don't know what to do with him and how to help him overcome this problem. Perhaps someone with more experience could advise?
