Goldilocks is an interesting technique and basically doing the opposite of estimating: You shape the work into the desired sizes.
- Vote each item into one of three piles: “Too Big”, “Just Right”, and “Too Small”.
- Split any “Too Big” items into “Just Right”-sized ones.
- Group any “Too Small” items together into “Just Right”.
The Goldilocks Principle applied to sorting stories reminds of potato grading machines that sort potatoes into different sizes.
Enjoy the flow.

- David uses ‘risk profiles’ to find out what to pull next. If
success + risk = 1 you can invert a ‘risk profile’ into a ‘success profile’ if you will.
- Chart uses a polar chart rather than a radar chart.
- Create success profile on an index card for every option you want to execute soon.
- Put it into corresponding swim lane, honoring any work in progress limit.
