Fleet & maintenance

Tacit Tessera O R 8 001 GN · 1 · Office · Records · collected by Strategic Agent · Specified — written down and numbered, not issued. The name is the address; the number is how the register writes it down.

Scope — what it covers: Will cover how equipment of the same class has behaved in service, and a maintenance interval plan set against fleet histories. It stops at decision support: the maker's requirements and the judgement of the person signing the work stay with the customer.

Refuses — where it stops: It refuses when the records do not support an answer, and when an answer would expose a single job's figure. Figures leave only as bands over many jobs.
