Agility Based On Business Rules: Just Common Sense
Today's business systems aren't agile - even when agile software methods are used to develop them. Companies need business agility, and, in most cases, people aren't delivering it. Here's an example from recent experience. The author had visited a very large health care organization and had conversations there with a variety of people. One manager confided to the author that making a change to business rules of even moderate complexity took them 400 person-days over a 4-month period. That's staggering. It's simply not sustainable. Unfortunately, their experience is not really that far from the norm. It's safe to say that this organization, like many today, is living in what the author calls change deployment hell.
