The everyday problem
When two systems can update the same information, disagreements can become an operational problem. Staff may not know which version to trust or whether an update will be overwritten. The integration needs a rule for ownership, not merely a connection between endpoints.
A practical approach
Document the authoritative source for important fields and the permitted direction of updates. Clarify how conflicts and corrections are handled. Include business owners in these decisions because technical connectivity does not establish the meaning of a field.
Try this with your team
Choose five fields used in a workflow and write their source of truth, allowed editors, and expected synchronization behavior.
