BIDROOM IN A BOX™
PRODUCTION NOTE

Roll Call · Stage 02

Every requirement called out by name

Roll Call™ is the second stage of the Bidroom in a Box™ workflow. It indexes every page of the tender pack, extracts every requirement, maps each one back to its source document and clause reference, assigns an owner, and records where the response will land in the submission. Open RFIs are routed to Question Time™ at Stage 03; everything else flows into Scope, Cost Stack and the client deliverables.
