Inclusive Grouping of Tasks and Subtasks Adding medium-specific subtasks increased the number of subtasks in the model from eight to 29. The next step in the hierarchical evolution of the value model was to generate functions. Functions Functions are the high-level, aggregated tasks that must be accomplished to attain the overarching objective of air and space dominance. Awareness is specified by the tasks detect, understand, and direct. To have reach requires the ability to deploy, maintain, and replenish.
Power comes from the ability to engage and survive.
Reach - ability to move to expand the range or scope of influence or effect, and to sustain this influence or effect by maintaining and replenishing. Power - ability to overtly or covertly affect, control, manipulate, deny, exploit, or destroy targets, including forces, people, equipment, and information, and the ability to survive while affecting targets. Two critical implications appear when the requirement for a set of functions in a value model are mutually exclusive and collectively exhaustive. First, these three Air Force 2025 functions should encompass every future air and space force operational activity. Second, awareness, reach , and power are the only operational activities that contribute to the overarching objective of air and space dominance.
