Which elements are the mission critical elements?

• A. Who, What, Where, When, Why
• B. Who, What, Where, When
• C. What, Where, When, How
• D. Who, What, Why, How

Answer: (A)

Understanding a mission starts with the five Ws: who, what, where, when, and why. These elements define the fundamental purpose, scope, and constraints of the operation. Knowing who is involved establishes authority and responsibility; what states the objective or task to be accomplished; where sets the location or area of operations; when outlines the timing and sequencing of actions; and why explains the purpose and justification for the mission. How, by contrast, concerns the methods to achieve the objective and is not part of the essential information used to define the mission itself. The other options either omit one of the Ws or replace it with How, making them incomplete for accurately articulating the mission’s intent.
