Risk Matrix Maker
Build a 5×5 risk matrix. Add risks with probability (1-5), impact (1-5), owner and mitigation — they auto-plot in the right cell with a coloured pill. Auto-classified as Low, Medium, High or Critical based on score. Theme picker, auto-save and export.

How to use this risk matrix maker
- Type a project or sprint name and pick a theme.
- Click + Add risk and enter the name, probability (1-5), impact (1-5), owner and mitigation.
- Each risk auto-plots in its cell with a colour matching its severity (Low/Medium/High/Critical).
- Use the matrix to discuss priorities — focus on red Critical risks first.
- Export as SVG (vector), PNG, JSON (re-importable) or copy as text.
Frequently asked questions
How is severity calculated?
Severity = probability × impact. Score 1-4 = Low, 5-9 = Medium, 10-15 = High, 16-25 = Critical (using a 5×5 grid).
Why a 5×5 grid?
5×5 is the most common scale in PM, ISO 31000 and PMBOK. It gives enough resolution without false precision.
Why do my biggest risks often have low probability?
Catastrophic risks (data breach, fire, key person leaving) are usually low-probability but high-impact. They feel less urgent than common medium-impact risks but cost dramatically more when they hit. Focus mitigation budget on high-impact risks regardless of probability — the asymmetric payoff is worth the spend.
