Summary


In this chapter we examined the concept of scalability (in terms of both the product and the project) and how well XP copes with it.

As we discovered , there are certain key stumbling blocks in XP that prevent the process from scaling up as the project increases in size. In particular, the on-site customer and the coach roles provide a natural ceiling to the size of an XP project. The case study of a 50-person project at ThoughtWorks, Inc., provides a classic example of the cracks in XP becoming more obvious as the project grows. Further processes and documents must be put in place to counter its shortcomings, but these in turn reduce XP s touted effectiveness.

A much better approach would be to start with a process that is effective with small projects but is designed to scale up easily as the project grows in size. As luck would have it, we describe just such a process in the next chapter.
