Choose one

Keep several frictions in view while you map the business and apply the rubric. Then choose one for your first pass through the rest of the method. Choosing early, before comparison, can leave you improving the first thing somebody mentioned while a more worthwhile opportunity waits elsewhere.

Working through one selected opportunity lets the team learn whether it can define value, explain its ratings, design a useful experiment, observe adoption, and stop when necessary. As that process becomes dependable, you can consider more simultaneous work. The number should follow your ability to learn and support change.
