Which criterion states that a course of action must have a significant advantage over others?

The criterion that states a course of action must have a significant advantage over others is "Distinguishable." This means that for a proposed course of action to be considered viable, it should be clearly different and superior in its potential outcomes compared to the alternatives. This distinction helps decision-makers identify the plan that offers the most benefits while also considering the trade-offs involved. When one course of action stands out as having a significant advantage, it enhances confidence in its selection and indicates a thorough analysis of the available options.

Other criteria such as feasible, acceptable, and complete focus on different aspects of evaluation. For instance, "feasible" addresses whether the course of action can realistically be implemented given the available resources and constraints. "Acceptable" evaluates if the proposed action does not come with undue risk or is aligned with broader objectives and political considerations. "Complete" ensures that all necessary components of the course of action are fully addressed. However, none of these criteria specifically points to the necessity for one option to have a significant advantage over others, which is the essence of being distinguishable.
