With Agile's focus on the current sprint, too many folks do not look ahead especially when it comes to database design. Looking forward down the road and incorporating flexibility in the database design goes a long way to making projects smoother. Also, making database changes are not as hard as it is to get developers and DBAs properly communicating. Of course, circumstances and plans change but that should be expected and anticipated. We all need to get our heads out of our task at hand, look around, communicate with each other, and plan for the future in order to develop solutions that not only meet expectations but exceed them.
