Step 6: Visualisation and interpretation
To provide an optimum basis for decision making, the previous steps’ results: aggregated, detailed, absolute and normalised information can and should be prepared for the final evaluation procedure.
1. Overall score
Firstly, the overall score is calculated by adding together all of a measure’s normalised, weighted effect-scores.
The overall score indicates the performance of the different measures relative to one another. The scores serve to rank the measures according to the effects and weighting provided. As such, negative scores are not indicative of ‘bad’ measures.
Additional to the overall score, additional information gathered during the assessment can be organised to provide more information to assist decision-makers, e.g. performance within different effect categories or weighted, normalised performance vs. unweighted, normalised performance.
