4-24. When executing stability operations, commanders integrate and synchronize military and nonmilitary tasks through collaborative planning. Therefore, every operation focuses on clearly defined, decisive, and attainable objectives. However, these objectives may evolve over the course of an operation, as strategic and operational guidance is refined, conditions of operational environment change, and understanding increases. Hence, all commanders continuously monitor operations and assess their progress against measures of effectiveness and the end state conditions. These conditions form the basis for decisions that ensure stability operations progress consistently toward the desired end state.
