Incorporate all business-essential processes and related interfaces, as defined by product owners, during validation sessions, user acceptance testing, or equivalent procedures to accurately present system capability.
Enhance the test plan to incorporate a more robust, risk-based testing process that incorporates user-testing requirements for functional and nonfunctional business-essential processes related to interfaces.
Develop a process to confirm with affected administrative offices whether they are aware of needed changes to test environments and that they have sufficiently executed them before interface test events.
Develop a method to evaluate whether test deficiencies necessitate changes to the deployment schedule to ensure deficiencies are properly addressed before wave go-live and implement these changes.
