In Quantitative Analysis for Management book, there are a few methods presented such as Decision Trees, utility theroy, and Bayesian analysis that involve some decision analysis and assumptions.

What is the likelihood that you would ever use these methods in your work when:

[1] You are the sole decision maker?

[2] You are part of committee that includes your boss in making the decision?

Please, provide your answer with example? Thanks
