Just think about what is being managed, and what the goal is.
Example: post-hurricane emergency management. Resources must be known--this involves personpower, transportation, supply chain, government coordination, et cetera. Planning is the art of Logistics, in part, involving how resources are assembled, moved, and distributed. There must be support for everyone involved--everything from field kitchens, cooks, restroom facilities, tents, cots, and safe places to put them for staff and displaced population.
