Appendix C: Decision-Making Models

Abstract

Project teams need to make many decisions of various magnitudes constantly throughout the life of the project so it’s a good idea to agree on a decision-making methodology early. This methodology should be identified and agreed upon near the end of the Initiating Phase or at the beginning of the Planning Phase, so let’s talk about the four most commonly used methods for making decisions. Here, we will cover the strengths and weaknesses of the models and provide some guidance on when to use each one.
