I disagree. Placing a time cap on finding , fixing, and documenting the root issue of a bug incentivies beating the clock over working the actual issue. However, this all depends on the buisness goals for a software development team. If long term stability is not that important, then I can understand why a time cap for fixing a bug is encouraged. Ideally though I would encourage developers to find organisations that allow developers to understand the root of an issue before fixing it.
