From live signal to a defensible plan: the Mana OS methodology.

Marketing planning has historically traded among three constraints: speed, cost, and quality. Mana OS is a planning operating system built to hold all three at once. It combines a continuous, multi-platform measurement layer (Signal) with a stateful, method-grounded decision layer (Canvas), run by an orchestration harness that carries strategic context across every step from brief to proposal. This paper describes the system's design principles, the construction of its ten analytical lenses, the evidence base behind its media planning logic, and the human checkpoints that keep every recommendation auditable. It is written to explain how the system works and why its outputs can be trusted. Specific model weights, scoring thresholds, agent contracts and prompts are proprietary and are deliberately not disclosed.
