The Speed Car retrospective uses the metaphor of a racing car to help agile teams review their last sprint. Participants define the elements that are driving the team forward (Engines), those that are slowing them down (Brakes), and the people who are supporting the team (Pit Crew).
The Speed Car retrospective is somewhat similar to an Anchors and Engines retrospective as it’s great to use in the middle of a project; especially when velocity is a concern. Where it differs, is its inclusion of the ‘Pit Crew’ dimension. This encourages team members to acknowledge the successes and support of others. In doing so an element of team building is included.
