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
- 1.1 Functional hierarchy: ISA-95
In complex manufacturing environments, blurring the lines between business planning and machine control is not an "agile" feature; rather, it introduces structural vulnerability. The ISA-95 standard a...
- 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, inte...
- 1.3 System landscape & RACI
A manufacturing floor operating with undefined system boundaries inevitably risks data corruption. When an ERP system attempts to manage millisecond-level sensor data, or a PLC tries to query financia...
- 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, Maste...
- 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 beyon...
- 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 believe...
