After the first workflow
The second workflow starts on what the first one built.
The first workflow leaves behind the infrastructure the agent runs on, the connection into your records, and the controls that governed it. The second workflow starts on that foundation; the third starts further ahead again. Estimating is a common first move — then the work around it: tendering, contracts, document control, procurement, project controls, HSEQ. Each addition is scoped like the first, measured like the first, and passes its own keep-or-stop gate. Nothing rolls over because the last one worked.
The gains compound the same way — hours back on the desk, more work priced and checked by the same team, evidence ready before the review asks for it.
