We created a series of Visio 2003 stencils last September to support our series of articles on BPMN. Anthony Britton has created a Visio 2002 version of the stencils for people who do not have Visio 2003 (or Visio 2007).

Agile Development of Use Cases
We proposed a strategy for developing use cases as part of an agile development methodology last week. In this article, we will look in more detail at that proposal, and also look at a specific way to apply agile techniques to the development of the use cases.
