Which measure evaluates against the desired effect?

• A. MOP measures against the tactical task
• B. MOE measures against the desired effect
• C. MOE measures against the tactical task
• D. MOP measures against the desired effect

Answer: (B)

The key idea is that measures of effectiveness are used to judge whether the operation achieved its intended end state, while measures of performance assess how well the system or action can do its job. In SEW testing, you want to know if the desired effect on the threat or environment actually happened, not just whether the system completed a task.

That’s why the correct choice uses MOE and measures against the desired effect. It ties the assessment to the end result you’re aiming for, such as reducing the adversary’s capability or achieving a specific tactical outcome.

To connect it to an example: if the goal is to degrade radar availability by a certain amount, an MOE would quantify how much the radar performance actually declines, reflecting the real-world impact.

Why the others don’t fit: MOP against the tactical task would focus on how well the system performs the action itself, not whether the action produced the intended end state. MOE against the tactical task would wrongly measure the effect in terms of a task parameter rather than the actual end-state impact. MOP against the desired effect would be mismatched because MOPs don’t assess the outcome on the enemy or environment; they assess the system’s ability to perform tasks.
