PRACTICAL GUIDE
Development & acceptance
Build and test to the agreed scope, then accept against inputs, outputs and exception cases.
Review milestones
Work advances through confirmed requirements, demonstrable versions, testing and acceptance. Scope changes record their cost and timing impact before agreement.
Test actual scenarios
Check outputs, permissions, duplicate requests and recovery using agreed inputs. A successful demo does not establish that every customer system is connected.
Delivery checklist
Receive the version, configuration guide, acceptance record, operating guidance, service term and exit arrangements. Ownership and reuse follow the contract.
