4-22. Staffs keep their units well informed. Staffs also keep adjacent, coalition, allied, and civilian organizations informed with relevant information according to security classification and need to know. Staffs have an obligation to establish working relationships with unit members. As soon as a staff receives information and determines its relevancy, that staff passes that information to the appropriate headquarters. The key is relevance, not volume. Masses of data inhibit mission command by distracting staffs from relevant information. Effective knowledge management helps staffs identify the information commanders and staff elements need, and its relative importance.
