Ward Cunningham on dealing with new requirements

Via Bill de hÓra, here’s an interview with Ward Cunningham: Working the Program. A great bit on how you accomplish emergent design:

But the nature of the work is first changing the program so the new requirement is an easy fit, and then doing the easy work to incorporate the requirement.
