A Prioritization Matrix scores options against weighted criteria so teams can compare choices transparently and select the most important work.
Definition
A Prioritization Matrix is a decision tool that compares options against criteria such as impact, urgency, cost, risk, feasibility, customer importance, and strategic alignment. Criteria may be weighted so the final ranking reflects what matters most.
It is useful when teams have more ideas, projects, causes, or actions than they can execute immediately.
History
Matrix-based prioritization grew from quality planning, decision analysis, and project-selection practice. Lean Six Sigma teams use it to move from opinion-based selection to transparent, criteria-based choices.
When to Use
Use a Prioritization Matrix when selecting projects, ranking root causes, choosing countermeasures, evaluating CTQs, prioritizing risks, or comparing improvement ideas. It is best when criteria can be agreed before scoring options.
Step-by-Step
- Define the decision and list options.
- Select criteria and operational definitions.
- Weight criteria if some are more important.
- Score each option using evidence where possible.
- Multiply by weights and total the scores.
- Review sensitivity and challenge questionable scores.
- Select priorities and assign next actions.
- Document assumptions and revisit if facts change.
Examples
- Project selection: Projects are scored by savings, customer impact, feasibility, and strategic fit.
- RCA: Potential causes are ranked by evidence, impact, and controllability.
- Kaizen: Improvement ideas are prioritized after a gemba walk.
Common Pitfalls
- Choosing criteria after seeing preferred options.
- Scoring without evidence.
- Overweighting easy work and ignoring risk.
- False precision from too many scoring levels.
- Not involving affected stakeholders.
- No action after ranking.
