The handoff is usually too late
By kickoff, the implementation date, scope, SLA, custom work and commercial concessions may already be committed.
Delivery can optimize execution, but it cannot always repair economics that were fixed earlier without reopening the customer conversation.
Where the hidden cost appears
Extra specialist hours, project-management overhead, out-of-scope support, temporary workarounds, weekend coverage, duplicated tooling and customer-specific processes can all look small individually.
Across a long service term, those costs can quietly change account economics.
Bring operating reality into the promise
A practical clearance should test the delivery plan before the promise leaves the company: capacity, dependencies, customer responsibilities, product readiness, implementation sequence and service-level feasibility.
That does not mean Delivery approves every deal. It means the decision uses delivery reality before the company makes the promise.
