The Entire Plant Needs a Fresh Coat of Paint So

The entire plant needs a fresh coat of paint so you, as the operations manager, are 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 strongly positive references are 9 or better on a ten-point scale and positive references are 7 up to 9 on a ten-point scale. 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.
