Lower-level publications should never what?

Lower-level publications should never contradict higher-level publications because consistency and coherence in the information being disseminated are crucial for effective communication and adherence to policies or standards. Higher-level publications typically contain established guidelines, regulations, and protocols that have been thoroughly vetted and approved. If lower-level documents contain contradictory information, it can lead to confusion, misinterpretation of procedures, and potential compliance issues. Ensuring that lower-level publications align with the directives set out in higher-level documents helps maintain a clear hierarchy of information and supports the integrity of the organization’s communication strategy.

The other options highlight considerations such as the need for approval before issuance, the appropriateness of dissemination practices, and the frequency of updates, which are important but not as directly related to the fundamental requirement of maintaining alignment with higher-level publications.
