qualitative risk assessment
Risk assessment methods based on a categorical classification of risk. The classification is often on two scales, ‘likelihood’ and ‘impact’, to give, for instance, a 3×3 table (called a risk matrix) with nine categories from ‘low likelihood/ low impact’, to ‘high likelihood/ high impact’.
This definition is abridged from A – Z of tree terms: A companion to British arboriculture.
