Outcomes Over Output

Why customer behavior is the key metric for business success

Measure changes in customer behavior, not features shipped.

by Joshua Seiden

In this short, focused book, Joshua Seiden makes the case that outcomes (measurable changes in customer behavior) are the real metric of success, not the volume of features produced. He offers practical guidance on defining outcomes, using them to set direction, and connecting them to OKRs and roadmaps. The brevity makes the core idea easy to absorb and apply.

Founders easily fall into the build trap of measuring progress by output, and this book reframes success around customer behavior. It gives a simple, actionable way to set goals and roadmaps that focus the team on impact. The concise format means a founder can read it in an afternoon and act on it.
