This article provides a practical framework for discussion. The right answer depends on the specific Dynamics 365 configuration, requirements and constraints of your organisation.
Critical processes tested
Evidence should cover end-to-end business scenarios, not only isolated configuration.
Finance reconciled
Opening balances, subledgers and key control accounts should reconcile.
Cutover rehearsed
Critical cutover steps should have owners, timing, dependencies and rollback decisions.
Defects understood
Open defects should have clear impact, workaround and acceptance decisions.
Users ready
Training, security and operational ownership need to be in place.
Support model active
Hypercare, escalation routes and issue triage should be ready before deployment.
Leadership aligned
The final go-live decision should reflect evidence from Finance, IT and programme delivery.
Use a focused review to separate root causes from symptoms and define the right next action.
