Treat implementation as a business operating change, not a configuration event.

State the observable business outcome and map the current workflow before selecting a product or provider.

Separate business accountability, technical work, data approval, security review, user acceptance, and vendor responsibility.

Write ordinary, exception, access, migration, reporting, recovery, and user acceptance checks before configuration begins.

Test exports, restoration, administrator control, documentation, manual work, support, and the decision deadline for rollback.
