Lean Startup

Definition

A methodology by Eric Ries centered on the Build-Measure-Learn feedback loop. Teams create a Minimum Viable Product, measure how customers respond, and learn whether to pivot or persevere. The goal is to minimize waste by validating business hypotheses as quickly and cheaply as possible. PMs apply lean principles to reduce the risk of building products nobody wants.

Why It Matters for Product Managers

Understanding lean startup is critical for product managers because it directly influences how teams prioritize work, measure progress, and deliver value to users. PMs apply lean principles to reduce the risk of building products nobody wants. Without a clear grasp of this concept, PMs risk making decisions based on assumptions rather than evidence, which can lead to wasted engineering effort and missed market opportunities.

How It Works in Practice

Teams typically implement this framework by following a structured process:

  • Introduce — Share the framework with the team, explaining the problem it solves and when it is most useful.
  • Calibrate — Run a practice session with a small set of real examples so the team develops a shared understanding of how to apply it.
  • Apply — Use the framework on actual backlog items, roadmap decisions, or discovery questions during a dedicated working session.
  • Review — After a cycle (sprint or quarter), evaluate whether the framework produced better outcomes and adjust how the team uses it.

    • The goal is not to follow lean startup dogmatically but to use it as a thinking tool that brings structure to decisions that would otherwise rely on gut feel.

    Common Pitfalls

  • Applying the framework mechanically without understanding the reasoning behind each step.
  • Using the framework as a substitute for product judgment rather than as an input to decisions.
  • Skipping calibration sessions, which causes inconsistent scoring or categorization across the team.
