Governance reviews keep AI use aligned with the rules set during the build: which tools staff may use, how data is handled and where human oversight applies. As models improve, older automations sometimes deserve a rebuild, and periodic reviews surface those opportunities before frustration builds.
Many companies later extend the programme, adding agents where automation proved value or expanding the company brain as knowledge grows, since components were scoped to stand alone.
The measure of success is simple: months after handover, the systems should still run, the team should still use them, and the roadmap should have a next step already written.
That is what separates transformation from a project that quietly ends.
