How to select an MES without starting from vendor demos

The best MES is the one that fits the plant's execution model and can be supported over its lifecycle. Vendor demonstrations should validate requirements, not define them.

Document the manufacturing processes

Map order release, dispatch, material issue, production confirmation, quality checks, exceptions, rework and completion before writing software requirements.

Separate must-have from attractive features

Traceability, regulated records or specific interfaces may be mandatory. Advanced analytics or AI may be optional. Make the distinction explicit.

Manufacturing fit

Discrete, batch and continuous operations have different data and workflow needs. Evaluate the product against representative production scenarios.

Integration fit

Review supported APIs/protocols, ERP connectors, identity integration, edge architecture and data-export options. Integration cost can exceed license cost.

Lifecycle and support

Consider upgrade path, vendor support, implementation ecosystem, configuration portability, testing tools and exit/data-retention options.

MES terminology and boundaries vary among plants and vendors. Validate data ownership, safety impacts, interfaces and change control against your actual manufacturing architecture and approved procedures.
