This document discusses effective command of collectives. It explores defining commands at both a higher conceptual level, considering interactions between commands, and a lower level looking at individual command elements. Command by intent aims to express the purpose and desired outcome without dictating how to achieve it, allowing for flexibility and novel behavior. Successful command of collectives requires understanding the interplay between different commands, flexibility to adapt to situations, and awareness of organizational cultures. Hurricane Katrina response failures demonstrate the need for these elements.
