Another source that talks about the need to maintain design integrity is the work of (Les) Belady and (Manny) Lehman. Like Brooks, they used the IBM 360 system data/experiences to address design as well as project “control,” esp. for large efforts.

Peter, the length of the loan should always be less than an iteration so that loans don’t gather interest from iteration to iteration.

Well put. Someone in my travels, I heard someone say that patching an application is like taking out a loan from a bank. Sooner or later, you have to pay it back — with interest. In the context of your post, one can say that the loans can be taken out in manageable amounts, then promptly repaid. Or, the debt from the loans can build up to the point where the application is “bankrupt.”
