Core PM ConceptsB

Backlog

Definition

An ordered list of all work items -- user stories, bugs, technical debt, spikes, and improvements -- that a product team may deliver. The product backlog is owned by the PM and continuously refined (groomed) to ensure the highest-priority items are well-defined and ready for development. A healthy backlog reflects current strategy and is not an ever-growing wish list.

Why It Matters for Product Managers

Understanding backlog helps product managers make better decisions about what to build, how to measure success, and where to focus limited resources. Teams that master this concept ship more effectively and maintain stronger alignment between business goals and user needs.

How It Works in Practice

Product teams put this concept into action 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 backlog compounds over time. Teams that commit to it consistently see improvements in velocity, quality, and cross-functional alignment.

    Common Pitfalls

  • Treating this as a checkbox activity rather than embedding it into daily team habits.
  • Applying the concept rigidly without adapting it to the team's context and maturity level.
  • Failing to communicate the purpose behind the practice, which leads to team resistance.
