Which of the following helps answer the question "Are we doing the right things?"

The correct answer is related to the concept of assessing whether the actions taken are resulting in the desired impact and achieving the overall objectives. In the context of the Military Decision-Making Process (MDMP), "Measure of Effectiveness" specifically evaluates whether the objectives and goals set forth in a mission or operation are being fulfilled. It provides a qualitative assessment of the success in achieving the desired end state or outcomes.

This measure focuses on the impact of actions rather than just the actions themselves, allowing leaders to gauge whether their plans and strategies are on the right track towards achieving their goals. It addresses the broader strategy and overarching purpose behind operational actions.

In contrast, other options like Measurement of Performance, Measurement of Outcome, and Measurement of Execution, while important in their own right, typically focus more on the implementation, completion, or specific tasks rather than the overall effectiveness and alignment with strategic objectives. They help in different stages of evaluation but do not directly answer the question of doing the "right things" in the context of achieving desired outcomes.
