Which step is NOT part of the operational methodology?

The step that is not part of the operational methodology relates to understanding public sentiment. Operational methodology primarily focuses on the analysis and execution of tasks within a defined environment, which encompasses understanding the problem at hand, the strategic direction provided by higher authorities, and the operational environment in which actions take place.

Understanding public sentiment, while important in broader strategic contexts, does not fall under the direct operational methodology employed in plans and actions within military or organizational operations. Operational methodology is more concerned with tactical elements and the mechanics of operations rather than the public's emotional or social views. Thus, public sentiment may influence decision-making at higher strategic levels or affect overall public relations but does not typically feature as a core component in the practical steps of executing operational plans.
