Implications for the Manager
The main points from this chapter are as follows:
• Multiattribute decision analysis is necessary for many real-life decisions.
• Keep multiattribute scoring as simple and transparent as possible. Avoid complex weighting, ranking, and scoring systems.
• Tie your subjective attributes back to your objectives hierarchy. If they don’t match, either your objectives hierarchy or your attributes are not correct.
My recommendation is to build these principles into your procurement procedures. The first decision when buying something is “Can we live with accepting the low bid?” If the answer is yes, you do not need multiattribute analysis. If the answer is no, you need to work to develop the beauty versus cost graph.
