ERP plans; MES adds execution context
ERP connects enterprise activities such as materials, purchasing and planning. MES records and coordinates execution closer to the shop floor. Their responsibilities overlap at the handover between planned work and actual production.
Define what needs to cross the boundary
A production order may flow to execution; quantities, rejections and completion status may flow back. Assign an owner to each field and reconcile identifiers before adding more interfaces.
Treat exceptions as part of the design
Decide what happens when an order changes after work starts, a message arrives twice or a connection is unavailable. Acceptance testing should cover those situations as carefully as the happy path.
Put this into practice
- List the records owned by ERP and those owned by MES.
- Identify the planning-to-execution handover.
- Document which status changes need to return to planning.
