Outcomes over Output: Why Customer Behavior Is the Key Metric for Business Success

Joshua Seiden and Jeff Gothelf make the case that teams should measure success through changes in customer behavior rather than features shipped. The core argument is that outputs (releases, story points, velocity) tell you nothing about whether you’re creating value; only behavioral outcomes reveal impact. This thinking is foundational to the Impact-Outcome Model and directly informs how we frame the output-activity trap that most product organizations fall into.
