2-8. Army design methodology results in an operational approach, a broad description of the mission, operational concepts, tasks, and actions required to accomplish the mission (JP 5-0). A good operational approach provides the basis for detailed planning, allows leaders to establish a logical operational framework, and helps produce an executable order. As detailed planning yields new information, leaders reassess their operational approach—and the Army design methodology that informed it—and adjust it accordingly to ensure relevancy. These actions continue throughout preparation and execution, and they inform commanders’ decision-making. When assessing operations, the logic of the operational approach provides the basis for developing assessment criteria, including measures of performance and effectiveness.
