Customise the risk matrix

The risk matrix turns a (likelihood, severity) pair into a risk level — Low, Medium, High, Very High. SteadyOn ships with a sensible default 5×5 matrix; you can replace it with one tuned to your org’s appetite.

Steps

1. From the sidebar bottom dock, click Organisation Settings.
2. Open the Configuration tab.
3. In the left rail, pick Risk matrix.
4. The matrix appears as a grid: likelihood across the top, severity down the side, with each cell coloured by its risk level.
5. Click any cell to change its risk level.
6. Save.

What’s in the default

The default 5×5 matrix:

	Insignificant	Minor	Moderate	Major	Severe
Almost certain	Medium	High	Very high	Very high	Very high
Likely	Medium	Medium	High	Very high	Very high
Possible	Low	Medium	High	High	Very high
Unlikely	Low	Low	Medium	High	High
Rare	Low	Low	Low	Medium	High

For the verbatim version, see Default risk matrix.

When to change it

You probably don’t need to. The default matches the matrix used in most published H&S guidance.

Reasons you might:

• Your industry uses a different scale (3×3 instead of 5×5).
• Your sector has explicit guidance (e.g. construction Code of Practice).
• You want to be more conservative — for example, a Possible × Major becomes Very High instead of High.

What does not change

• The likelihood and severity values themselves are lookups — customise them under Lookups → Likelihood / Severity in the same tab. Renaming “Almost certain” to “Frequent” doesn’t change the matrix; the position is what matters.
• Existing hazards keep the risk level they were given at the time of assessment until they’re re-edited. The matrix applies on edit, not retroactively.
