Which of the following is not a COA analysis method?

• A. Belt Method
• B. Avenue in Depth Method
• C. Box Method
• D. Graphical Method

Answer: (D)

COA analysis relies on structured methods to compare possible actions along key criteria such as feasibility, risk, and impact. The Belt Method, Avenue in Depth Method, and Box Method are examples of these structured approaches; they organize information about each course of action across defined dimensions to reveal trade-offs and dependencies. In the Belt Method, options are laid out along a central axis with surrounding variations to show how close or far they are from the objective. The Avenue in Depth method layers considerations as you move deeper into the scenario, helping you see how early choices affect later outcomes. The Box Method uses a grid to cross-reference factors like time, resources, and risk for each COA, making comparisons clear. A Graphical Method, while it can involve visual representations, is not a named COA analysis technique used in this context, so it is not considered a COA analysis method.
