Designing object-oriented software is hard, and designing reusable
object-oriented software is even harder. You must find pertinent objects, factor
them into classes at the right granularity, define class interfaces and inheritance
hierarchies, and establish key relationships among them. Your design should be
specific to the problem at hand but also general enough to address future problems
and requirements. You also want to avoid redesign, or at least minimize it.
Experienced object-oriented designers will tell you that a reusable and flexible
design is difficult if not impossible to get "right" the first time. Before a
design is finished, they usually try to reuse it several times, modifying it each
time.
