Which of the following is NOT a question addressed in mission analysis?

In the context of mission analysis within the Military Decision Making Process (MDMP), the focus is primarily on understanding the operational environment, the enemy's capabilities, and the overall mission objectives. The questions that are addressed during mission analysis help form a comprehensive understanding of the situation and guide the development of the plan.

The question regarding how to measure mission success is not typically covered in mission analysis. Instead, mission analysis is concerned with defining tasks, assessing available resources, identifying constraints and limitations, and anticipating enemy actions. It sets the groundwork for planning and execution but does not directly address how success will be quantified or assessed.

The other questions play a more direct role in mission analysis. "When to execute the operation?" relates to timing and synchronization, which are critical components of operational planning. "What is the enemy's next move?" focuses on analyzing threats and enemy capabilities, essential for determining the best course of action. "How to perform the operation?" pertains to the tactics and methods that will be used, which stems from the analysis of the mission requirements and available assets.

Thus, measuring mission success is not a primary focus during mission analysis, making it the correct choice for what is not addressed in that phase.
