Identify the decision the reader needs to make and the explanations and evidence required. Share coverage, claims to avoid, review responsibilities and internal links alongside search terms.
For a service comparison, a brief can specify comparison criteria, actual service scope, applicable conditions and sources to check. This is a planning example, not a claim that a particular client reduced revisions or production time.
Set length and headings according to what readers need to understand. Update the brief when new information emerges, then check that the finished statements agree with their evidence.
