Writing Complete User Stories

User stories can make requirements management a lot easier.  They shift some of the communication from up-front documentation to ongoing dialog.  That’s the main reason they work so well for agile teams.  And agile teams focus on “what’s next?” instead of an ever-changing “what’s everything?”   The problem is, when those conversations are working well, it is easy to forget to make sure that what you’ve done is actually enough.  Add a small dose of traceability, and you can easily validate the completeness of your user stories.

Agile Product Management: Providing Context

Agile development methodologies succeed because they help development teams be as effective as possible.  Development teams do not, however, work in complete isolation.  The company they work for has a strategy.  The company manages a portfolio of products, and targets a particular product at specific market problems.  Within that context, an agile team can thrive.  What’s the best way to provide that context?
