A.15.11:9 - Consequences

A useful method can enter work before the recipient formulates a search query. Its relation to the task becomes available for examination, including rejection. The arrangement can be as small as a question beside an existing estimate.

This adds preparation and maintenance costs and can create distraction. It also depends on someone finding a method worth introducing. It does not guarantee discovery of every unknown possibility. Repeated use can justify improving a shared arrangement; a one-off direct answer can remain the better choice.
