Often teams have lots of improvements to work on. From the Retrospective or daily struggles.
This sketch gives team a great view of what they’ve already accomplished and what’s still to do.
I use the rays to map the improvements on different theme’s.
The further the improvements are from the sun the smaller or more easy they are to achieve. Closer to the sun thing get hot and need more effort to accomplish.
Once an improvement is achieved I give it a nice bright colour. Celebrate the success, Have Fun!
