The core idea
A decision record captures what was chosen and why at a particular moment. It should preserve constraints and uncertainty, not pretend the choice was universally correct. Future teammates need to know which assumptions supported the decision and what change would justify revisiting it.
A practical approach
Step 1
Describe the problem, constraints and decision owner. Keep the scope narrow enough to fit a short document.
Step 2
List the meaningful alternatives and the trade-offs that mattered. Include the evidence available at the time.
Step 3
Record the chosen approach, consequences and review trigger. Link to implementation or experiment results as they become available.
Worked example
A team chooses written self-guided courses before adding video lessons because it can maintain them with its current resources. The record should explain that constraint and the evidence needed to reconsider, rather than claiming written content is always superior.
A mistake to avoid
A record that only says ‘we chose option A’ preserves the result but loses the reasoning. Conversely, copying an entire conversation makes the useful decision difficult to find.
Try it yourself
Document one recent product choice in five short sections: context, alternatives, decision, consequences and revisit trigger. Ask a colleague whether they can explain the trade-off from that record alone.
Your implementation checklist
- Context and constraints are retained.
- Alternatives are meaningful.
- Uncertainty is not hidden.
- A revisit trigger is explicit.
