Pilot scope, data contract, environment decision and commissioning handover: settle an integration project before going on site.
The difficulty of an integration project is usually in the scope rather than the software: which decision will improve, who defines the data, what happens in an outage and who operates the system?
This hub gathers guides that run from the scope of a pilot through the choice of runtime environment to the commissioning handover. The planner and the readiness check help you arrive at the discussion with a concrete brief.
Key concepts
Implementation guides
Start with one production line. Define data ownership, measurable acceptance criteria and failure scenarios before scaling an integration.
