OPS.17:2 - Problem
A named approach often bundles useful operations with assumptions about demand, resources, evidence and the purpose of the organization. Adopting the bundle can import an unsuitable objective or omit a condition that made its source example work. A local success also gives weak grounds for general use if the team cannot recover what was actually changed.
A catalogue creates a different difficulty: it preserves names but leaves every practitioner to reconstruct applicability. The needed knowledge is what each method lets the operation do, what it requires, and what observable change would defeat the claim.
