3-39. An effective mission command system anticipates and answers a commander’s information requirements. Commanders carefully allocate collection resources to obtain data and information for critical tasks. They set priorities for collection by establishing the CCIRs. Commanders widely distribute their CCIRs and revise them as the situation changes. Information is continuously collected. It may be delivered on a routine schedule or as requested. An information-push system pushes information from the source to the user as it becomes available or according to a schedule (such as through routine reports). An information-pull system supplies information as requested. Commanders and staffs determine how to use and integrate both types of systems.
