The using MAJCOM provides the following expertise: A planning organization, typically A5 or A8, responsible for maintaining a balanced overview of the organization’s top-level strategic situation. It ensures that all of the systems used by its operational (using) agencies form systems of systems (SoS) that work smoothly together to meet the current and future strategic needs of the organization. Measures of Outcome (MOO) usually come from a strategic agency point of view. An operations organization, typically A3, responsible for high-level system requirements, starting with operational requirements. This includes system usage scenarios, the Concept of Operations (CONOPS), and training. It must work with strategic agencies to ensure its current and future capabilities adequately address strategic needs, and must collaborate with other operating agencies to provide appropriate robustness (capability overlap). The Operations point of view is generally the source for Measures of Effectiveness (MOE), and may also provide some top-level Measures of Performance (MOP). A sustainment planning organization, typically A4, responsible for insuring that field supportability issues are properly addressed and integrated into the overall logistics support structure. Supportability MOPs such as reliability, maintainability, and training concerns come from a sustainment viewpoint. An Intelligence organization, typically A2, responsible for timely information regarding current and future capabilities and intentions of potential adversaries. Adversarial capabilities usually drive the establishment of system requirements (i.e., MOPs) sufficient to circumvent or defeat them.
