Extending a manufacturing KPI framework to tier-1 and tier-2 suppliers requires careful scoping, common definitions, contractual alignment, and pragmatic data integration. You typically cannot just push your internal dashboards outward. Instead, you need a staged model, clear data-sharing rules, validation of supplier data, and contingency plans for uneven system maturity across the supply base.

ERP is necessary in aerospace, but it is not sufficient on its own for execution, traceability, and compliance. Common gaps appear around detailed work execution control, digital travelers and work instructions, AS9100/AS9102 evidence, real-time quality and NCR workflows, configuration control, and robust as-built genealogy. These gaps are amplified in brownfield plants with mixed systems, legacy equipment, and strict validation and change-control requirements.

Aerospace manufacturers should usually integrate supplier portals with ERP through controlled interfaces, not by making the portal the new system of record. Start with narrow use cases, clear data ownership, and traceable transactions. Success depends on master data quality, integration discipline, security controls, and validation of workflows that affect quality, traceability, or export-controlled data.

MES and ERP both track material usage but at different levels and for different purposes. In aerospace, ERP usually manages inventory, costing, and procurement, while MES records unit‑level consumption, genealogy, and process context. Reliable traceability requires careful integration, configuration, and validation across both systems; neither replaces the other by default.

There is no fixed “right” number of status updates from execution to ERP. You need enough events to support planning, costing, and compliance, but not so many that you overload interfaces, users, or validation. Most plants converge on a small set of standardized milestones plus a few exception events, tuned by product risk, system maturity, and integration constraints.

No. A Manufacturing Execution System (MES) is not an ERP system. MES focuses on managing and documenting production on the shop floor, while ERP manages enterprise-level planning, finance, and resources. In regulated, brownfield plants they typically coexist, integrate, and partially overlap, which creates both opportunities and integration risks.

In regulated manufacturing, work orders are usually issued by planning or scheduling functions through an ERP, MES, or MRP system. The exact sender depends on how your plant is organized and integrated. Often they originate in ERP/MRP, are dispatched by MES or a planner, and must follow formal approval, revision control, and change processes.
