At the Lean Kanban conference in the Netherlands Astrid Claessen did a presentation on using game storming in your retrospectives.
The talk covered the following topics:
- Why retrospectives are important
- How restrospectives could (or rather should) be run (using the model from Derby & Larsen)
- What Gamestorming can add to the way you run retrospectives
A more extended version of the talk will be done at Agilesingapore.org.
