Template 13, by IT Economics Corporation (https://www.iteconcorp.com/T13EvaluateSources.html), is an example of a matrix used for summarizing the results of evaluating proposals received from IT services contractors. The template uses "adjectival" rating codes and brief statements to summarize the evaluation results of each proposal from IT services contractors.
