Build-ready does not mean exhaustive. It means the consequential decisions are explicit, testable and owned.
More than a requirements list
A backlog can describe features while leaving the programme undefined. Teams still need to know who operates the service, where data authority sits, how systems interact and what evidence permits release.
A build-ready specification connects the mandate to those delivery decisions. It is detailed where ambiguity creates cost and deliberately open where builders should retain choice.
The minimum coherent package
The artefacts should work as one decision system rather than as separate documents.
- Mandate, outcomes and measurable success conditions
- Service journeys, functional scope and exception paths
- Target architecture, data model and interface contracts
- Control framework, operating model and decision rights
- Delivery plan, commercial assumptions and risk register
- Acceptance evidence and transition conditions
A specification remains live
Once delivery begins, the specification becomes the reference for change, acceptance and executive decisions. It should evolve with evidence without losing the rationale behind earlier choices.
