The entire Campus at University of the Commonwealth Caribbean (UCC) needs a fresh coat of paint so you, as the Materials Manager, is charged with securing a painting contract to accomplish this. You locate four painting contractors and ask them for their performance on four criteria. Their responses, along with your minimum standards and the importance you place on each criterion, is shown in the table. Note that Management has agreed to use a five-point scale (Excellent/strongly positive = 5, Very good/positive = 4, Good = 3, Fair = 2, Poor = 1) to quantify and compare their subjective opinions about the criterion. Assign scores from 1 to 5 where 1 is terrible and 5 is excellent, for each contractor's performance on each criterion and determine who should be awarded the contract. 

Write a brief explanation for all the 1s and 5s you assign. (8 marks)
