Definition and worked example

See the method before entering your own evidence.

Who should use it: Test whether a proposed category exists beyond your own language.

Decision basis: The category evidence matrix separates buyer and market evidence from company assertion. A confirmed category row requires a buyer problem, budget owner, multiple plausible members, and at least one independent use of the term.

Buyer problem: Senior teams cannot tell which market assumptions have expired.
Actual buyer search phrase: strategy assumption audit
Budget owner: Chief Strategy Officer
Named alternatives: Consulting review, planning offsite
Plausible category members: Strategy firms, research platforms, planning teams
Independent use of the term: Two industry newsletters use the term
