Estimating

Tacit Tessera O R 1 001 GN · 2 · 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 work in this field has gone on real jobs — what a scope has usually involved and what has usually gone wrong — and an estimate sheet for the customer's own job: a price band, coded comparables, risk flags, assumptions and what is missing. It is decision support; the sign-off stays 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.
