An ERP plan full of dates can look certain while the factory cannot possibly meet it. This episode is for manufacturing planners, operations leaders and IT architects deciding between ERP scheduling and dedicated APS software. You will learn what each system does well, when APS becomes hard to avoid and how to divide ownership between ERP, APS and MES.

Key takeaways
Worth quoting
“Confusion starts when a planned ERP date gets treated as proof that the factory has the capacity to deliver.” – Mirko Peters (04:42)
“somebody still has to decide the order in which those jobs run, where the setup time goes, and which job waits when the day runs out. The date didn't solve those decisions, it postponed them to whoever releases the work.” – Mirko Peters (11:09)

- 00:00 – One order, two views of the factory
- 04:49 – What ERP does well
- 09:52 – Why ERP plans look more certain than they are

Key takeaways
- ERP is the governed system of record for demand, supply, inventory and transactions, while APS tests whether the plan can actually run under finite capacity and real constraints.
- A feasible schedule depends on detailed constraint data such as calendars, qualified labor, tools, setup rules and material readiness, plus explicit business priority rules.
- APS supports rather than replaces the planner, and clear ownership across ERP, APS and MES matters more than the number of integrations.
