When I wrote about the Broken Window Fallacy in Software Development a while back, it appears that there were a number of misunderstandings.

• First, there is a fundamental difference between the economic Broken Window Fallacy and the "ghetto-ization" that comes along with the sociological/psychological aspects of the Broken Windows Phenomenon. I've already covered that difference.
• Second - and much more importantly - that doesn't mean you should never rebuild something!

I simply believe that you should be selective in your choices.. Every day you spend rebuilding something that works is one day that your competition has to catch up or get ahead.

That said, there are a number of times where rebuilding might make sense... but consider it carefully. Before you do anything else, just STOP. Don't go any farther until you ask yourself one question: "What's the goal here?"
