“Cause & Effect and Product Risk” is a good good post by Scott Sehlhorst on the importance of moving to an outcome-based approach when evaluating and planning product features. He also discussed how to use Impact Mapping to do it:
When we collaborate to develop a shared understanding that explicitly connects “building X” with “realizing benefit Y” we address the first problem. Impact maps are great for this, because in the process of creating the connections, we intentionally challenge those connections and explore others; creating a better plan, shifting to a bigger goal. All while providing deep context throughout the teams, increasing likelihood of successful delivery and effective stakeholder management.
