XP practitioners typically obsess about good design, taking it much more seriously than other developers. They simply have a different point of view on when to do it—all the time, instead of all at the beginning.
Design Today’s Features
Customers define which features are most important, and programmers work on those features first. As each new feature is implemented, the application is delivered to customers and they have the opportunity to offer immediate feedback.
In this customer-centric delivery model, we do not have time to spend months and months of time doing detailed design and analysis. We also cannot afford to develop complex frameworks to accommodate every anticipated feature. If we did either of these things, we would not be able to deliver working code (and thus get feedback) to the customer in a timely fashion.
Figure 2-2 shows the relationship between time-to-customer and the likelihood that the finished product does not meet expectations. Stated simply, the longer you work in a vacuum without getting feedback from your customer, the higher the probability is that you will develop the wrong features.
