Evaluation Scores - back to top

Evaluation Selection Matrix - tool used courtesy of TurboSigma®
NOTE: The weighting is a reflection of the relative importance of criteria, some being more important than others. Each option is evaluated against each criteria - the one that best satisfies the criteria gets 3 points, the next 2 and the last one 1. In the event that an option does not satisfy the criteria at all it can be awarded 'o' for that criteria. If two options equally satisfy a criteria they can be allocated the same points for that criteria.
Highest score signals best option
