Given the following matrix of various technical requirements, develop your own weighting factors for an inventory management system at a small plumbing supplier. Justify your weights. Extend the raw scores to the extended column and calculate the totals. Which would you choose? Justify your selection: Did you go strictly by the numbers, or are there other factors you might consider? How do you handle a number that is not given: give it an average of the others, pick the best of the others, guess a value, or assign a zero? (Raw numbers use a six point scale.)
