Each row is one risk scored for likelihood and impact to give an inherent rating, with the residual column showing what is left once the mapped control is in place and working.
Where inherent risk is high and residual is still high, the control is not yet doing its job. Where residual drops to low, the control is working and the risk sits within appetite.
The heatmap holds eight risks; names take up to 26 characters.
