When a business problem arises, there are comprehensive solutions and there are fast solutions. Fast solutions are easy and typically inexpensive, whereas comprehensive solutions may be slower and almost certainly cost more. In a post at Consulting 101, Lew Sauder discusses how the cheap solutions do not always turn out so cheap after all. Namely, if you have to address the same problem with some variant of the cheap solution multiple times, then it might add up to more than it would have cost to just go with the comprehensive solution.
Of course, not every problem really does warrant a comprehensive solution. Sometimes, it is a trivial problem deserving of a trivial fix. But it is important to understand root problems during such decisions, in order to get an accurate understanding of the costs involved.
