1 . Manufacturing systems architecture and ownership
Fragmented software silos create data islands that blind factory managers to the true state of production. The baseline of digital excellence is a unified, single-source-of-truth systems architecture.
This chapter outlines the structural hierarchy of our factory software stack. We define the clear boundaries between Enterprise Resource Planning (ERP), Manufacturing Execution System (MES), and machine-level controls, establishing strict data ownership and integration standards.
- 1.1 Functional hierarchy: ISA-95
In complex manufacturing environments, blurring the lines between business planning and machine control does not provide agility; instead, it creates a point of structural weakness. The ISA-95 standard acts as a crucial framework, preventing high-lev...
- 1.2 Interoperability and governance
A system architecture without governance is not truly an architecture; rather, it often devolves into a fragile topology of point-to-point connections. In a high-volume manufacturing environment, achieving true interoperability requires the disciplin...
- 1.3 System landscape & RACI
A manufacturing floor operating without clearly defined system boundaries is at significant risk of data corruption. Imagine a scenario where an ERP system tries to manage millisecond-level sensor data, or a PLC attempts to query financial ledgers. T...
- 1.4 Master data model & SSOT rules: BOM, routing, resources
Master Data functions as the executable code of the factory. If the Bill of Materials (BOM) or Routing contains an error, the MES will unknowingly automate the production of a defect. Therefore, Master Data must not be treated merely as static docume...
- 1.5 OT network & cybersecurity baseline
A flat network significantly increases risk. If a receptionist's laptop opens a phishing email, it is critical that the PLCs continue to operate safely. The primary goal of OT Cybersecurity goes beyond simple "IT Compliance"; it is about ensuring Pro...
- 1.6 ERP-MES contract: orders, confirmations, consumption, scrap, WIP
The interface between ERP (Enterprise Resource Planning) and MES (Manufacturing Execution System) is not merely a data pipe; it is a binding contract between Finance and Operations. If the ERP believes you have 100 units of raw material, but the MES...
