Flow Metrics vs. Estimates

Estimating can bring out strong reactions, and for good reason. Mike Cohn and Brian Milner unpack why it gets misused, what “estimate responsibly” really means, and how to use planning to make better decisions without turning numbers into weapons.

Overview

In this episode, Brian sits down with Mike Cohn to talk about estimating and planning in a way that teams can actually live with. They explore why estimates became such a hot button topic, what the “no estimates” movement is reacting to, and how Mike’s thinking has evolved over time. You will hear practical guidance on story points versus time, why teams should estimate only when it helps someone make a decision, and how to keep estimates from damaging trust. They also cover where flow metrics help, where they fall short, and how teams build credibility with leadership through responsible planning.
