@RLO: Well, the problem is that each member in my team is responsible for different modules, and don't have knowledge of work others working on.

And there's new module launching for my team this Monday, so lots of bugfixes are logged.

Btw, according to department meeting last month, 80% of teams (about 10) in my department have 1-2 vacancies in them, and most of the team size is 2-6 people. So there's really manpower shortage everywhere.
