Asking whether patterns and frameworks reduce discovery costs is like asking whether someone who knows something about billing is going to have an easier time making a billing system than someone who doesn’t. Of course! The problem is whether we have the right patterns and frameworks to reduce discovery costs. If not, how can we get them?

– Ralph Johnson

Too many projects look for the “home run” in reusable platforms and frameworks. Frameworks work well only if they can predict well: to predict what will change, and what will not. This is a difficult enough problem for individual objects or modules, let alone for extensible application skeletons. Small frameworks like MVC work, but few large frameworks enjoy success.
