There are several stages in the course of a project when critical decisions are to be made regarding the future path that is to be followed. In fact, the most crucial decision might be to decide at the beginning whether to embark on the project or not. Other important decisions that could benefit from using decision analysis tools may be subcontract awarding, subproject termination in a research and development (R&D) environment, what-if analysis, and so on. Decision analysis techniques can be used effectively in such situations to help make decisions under uncertainty.
