We cannot avoid change. A good architecture will adapt to change rather than fight it.

Requirement changes and modifications to the code, and their impact on the software application, depend on the actual scope and size of the application itself. So before we go ahead with examining how we can manage changes, we first need to understand how changes relate to the application's size and scope.

Small Applications Versus Big Applications

Web applications (or for that matter any kind of application that we may develop) can broadly be categorized as big or small.
