It is an all-in-one tool that supports both the creative and process-oriented aspects of military planning. In Onebrief, planners use maps, boards, diagrams, timelines, slides and written products to create their plans—all while sharing a common database. Everything stays in sync, in real time. Our approach has been refined and validated through hundreds of user experiments.Our product is currently in broad use at 8 of the largest military headquarters in the world. 3 of the 4 biggest operational plans in the US are currently built with Onebrief.
