I finished another essay on Fit today. As I look back, I realize that I've now closed the circle on a pretty substantial cycle of essays on agile requirements. I now cover everything from planning months of releases down to how to write a single section of a Fit document, the work of an hour. Not bad.

• Beyond Story Cards describes how I prefer to handle requirements over the course of developing an entire software product.

• Fit Workflow describes how I use Fit to facilitate collaboration on requirements during a single iteration.

• A Vision for Fit gives a concrete example of using Fit to facilite collaboration.

• How I Use Fit describes how I prefer to develop and structure an individual Fit document, its fixtures, and how software development comes into play.
