In every project I work on, there is an initial discussion on scope. In the almost decade of working on tech projects, I have never had a client who had a perfect scope in mind. There is a process of discovery where you delve into the goals, needs, desires of the client. Even when that process is smooth and everything is documented to a tee, as the project moves forward the client begins to see how things can be made better here or there.

A good example might be discovering that sorting a list by last name might achieve one business requirement, that requirement could be enhanced by allowing sorting by date.

I've been adding new modules to an instance of Drupal we're working with where I work. Organic Groups allows you to essentially set up private sub-sites within an existing site. It can even have its own theme (look and feel). PingVision--a company we're pretty interested in right now--mentioned it in a recent meeting. It is potentially a powerful tool in mananging projects from different clients in a single environment. Coupled with Project and some of Project's add on modules, you effectively have a bug management and project management tool.

I continue to marvel at what a versatile tool Drupal is.
