The starting question
A leadership brief can collect many desirable attributes without explaining what the person will actually do. Start with the business situation and the decisions the role owns. This makes the requirement more specific and easier to discuss with prospective candidates.
The working approach
Bring the relevant decision-makers into an early conversation. Separate essential experience from preferences, clarify the reporting relationships and describe the culture in practical terms. Record where the group agrees and where another discussion is needed.
The decision lens
Use the mandate throughout the search. A consistent brief helps the team evaluate evidence, understand trade-offs and explain why a particular background is relevant. Review the brief when the business context changes rather than quietly changing the criteria.
