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.
Is anything uploaded?
No. Auto-save uses localStorage on this device only.
