What term refers to the action one decides upon at the conclusion of the decision-making process?

The term that refers to the action one decides upon at the conclusion of the decision-making process is a "decision." In decision-making, individuals analyze information, weigh options, and ultimately arrive at a conclusion that informs their next steps. A decision embodies the choice made after considering various factors and alternatives, and it leads directly to an action or strategy to be implemented.

A plan, while it can be a result of a decision, typically outlines a series of steps to achieve a goal rather than the decisive choice itself. An outcome refers to the result of a decision once it has been acted upon, and a resolution might suggest a solution to a problem but does not specifically encapsulate the act of deciding. Therefore, the most accurate term for what occurs at the end of the decision-making process is "decision."
