Story Points

Definition

A unit of measure for estimating the relative effort, complexity, and uncertainty of a user story. Teams often use the Fibonacci sequence (1, 2, 3, 5, 8, 13, 21) to size stories. Story points are not hours; they are relative and specific to each team. PMs use story-point estimates to forecast velocity and plan sprints, not to measure individual productivity.

Why It Matters for Product Managers

Understanding story points is critical for product managers because it directly influences how teams prioritize work, measure progress, and deliver value to users. PMs use story-point estimates to forecast velocity and plan sprints, not to measure individual productivity. 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

Engineering and product teams leverage this practice by integrating it into their regular workflow:

  • Adopt — Agree as a team on how and when to apply this practice, making it an explicit part of the team's working agreement.
  • Execute — Follow through consistently, treating the practice as a non-negotiable part of how the team operates.
  • Inspect — Regularly evaluate whether the practice is delivering the expected benefits and surface any friction.
  • Adapt — Adjust the approach based on what the team learns, keeping what works and discarding what does not.

    • The value of story points compounds over time. Teams that commit to it consistently see improvements in velocity, quality, and cross-functional alignment.

    Common Pitfalls

  • Treating the practice as overhead rather than recognizing the quality and velocity benefits it provides.
  • Implementing the process without buy-in from the full cross-functional team.
  • Letting the process become rigid and bureaucratic instead of adapting it as the team learns and grows.
