Turn business intent into an implementation specification
Describe behavior, contracts, environments, failure handling and ownership without prescribing unnecessary technology.
Specify observable behavior
- State inputs, outputs, state changes and user-visible failure behavior.
- Keep business rules separate from implementation preferences.
Cover the difficult paths
- Include invalid inputs, duplicate events, unavailable dependencies, permission failures and ambiguous completion.
- Name the authoritative record and reconciliation owner.
Control change
- Version interfaces, acceptance and dependencies.
- Require a reviewed change when scope, data routes, authority or operating cost changes materially.
Keep the result reusable
The engagement studio carries the same workflow identity into six reviewable artifacts. It does not send a request, select a vendor, create a contract or approve a purchase.
