Production planning between ERP and shopfloor: why a specialised layer can help
The ERP knows orders and master data; production knows reality. A custom planning layer can connect both worlds.
ERP systems are strong at managing business transactions and systems of record. Operational production planning, however, often follows rules much closer to manufacturing reality: setup sequences, bottleneck resources, short-term priorities, material availability or expert knowledge.
The common tension
The ERP provides orders and dates. Detailed planning happens next to it in spreadsheets, boards or isolated specialist tools. Changes are transferred manually and feedback returns with a delay.
A custom production solution can act as a specialised layer here without replacing the ERP.
Data in, decision out, status back
A robust integration pattern often looks like this:
- Consume orders, master data and relevant inventory from the ERP.
- Apply production-specific rules and dependencies.
- Make bottlenecks, conflicts and alternatives visible to planners.
- Write approved plans or status information back to connected systems.
This keeps it clear which system owns which data, while domain logic is implemented where it creates the most value.
The key question is not “ERP or custom software?”
In many projects, the best answer is both. The ERP remains the stable core while custom software closes the gap created by the organisation’s unique production logic.
