Aerospace OEMs should not start with the entire supply base when pursuing deeper execution visibility. The practical approach is to prioritize suppliers where limited visibility creates the most risk to safety, delivery, and cost, and where data connectivity is realistically achievable.
1. Start with parts and processes that drive the most risk
Prioritize suppliers where loss of control or late information has the highest operational or compliance impact:
- Flight-critical and safety-critical parts (structures, flight controls, landing gear, engine components), especially those carrying special characteristics or key characteristics.
- Special process suppliers (heat treat, NDT, coatings, welding, composites curing) where you are heavily dependent on their process controls and records for your own AS9100/AS9102 evidence.
- High qualification burden items where any design or process change triggers significant requalification or new FAIs.
- Configuration- and traceability-critical parts (serialized major assemblies, rotating parts, life‑limited items) where incomplete as-built data creates audit and in‑service risk.
These suppliers should be first in line for deeper execution visibility because issues discovered late are disproportionately expensive and difficult to contain.
2. Focus on single-source, long-lead, and choke-point suppliers
Next, prioritize suppliers whose performance has high schedule and continuity impact:
- Single-source / sole-source suppliers where you have limited fallback options and expediting is costly or impossible.
- Long-lead components and materials (large forgings, castings, complex machined structures, avionics modules) where disruption cascades through multiple programs.
- Tier‑1 integrators and module builders that assemble and test large subassemblies and depend on their own sub‑tier networks.
- Suppliers feeding multiple key programs (commercial + defense) where slippage causes cross‑program conflicts.
Deeper execution visibility here (queue status, WIP, capacity constraints, yield) improves shortage management and program risk assessment far more than instrumenting small, low‑impact vendors.
3. Address chronic quality and on-time delivery problems
Use performance history to select suppliers where lack of visibility blocks effective corrective action:
- Suppliers with repeated NCRs, escapes, or systemic CAPA where current visibility ends at the shipping dock and root causes remain opaque.
- Suppliers with unstable OTD (large swings in lead time, frequent de-expedites/expedites) obscuring real capacity and scheduling issues.
- Suppliers with high rework or scrap that regularly request deviations, concessions, or waivers.
For these suppliers, execution visibility should support structured problem solving, not just monitoring. That typically means access to actual routing steps, process parameters, rework/hold records, and inspection outcomes, not only high‑level scorecards.
4. Consider digital maturity and integration feasibility
Not every high‑risk supplier is a good first candidate for deep integration. In brownfield environments, you need to balance risk with practical connectivity:
- Favorable near‑term targets tend to be suppliers that already run an MES, ERP, or quality system capable of structured data export (even if not yet standardized to your needs).
- More challenging targets are paper‑based shops or those with rigid, heavily customized legacy systems that make integration slow and fragile.
Early waves should combine high impact with reasonable data readiness so that pilot efforts prove value without stalling under integration and validation burdens.
5. Define what “deeper execution visibility” actually means
The level of visibility should match the supplier’s role and your risk appetite. Examples include:
- Basic execution visibility: planned vs. actual start/finish for key operations, queues, current WIP by routing step, shipment readiness.
- Process and quality visibility: operation‑level parameters, inspection results, rework/hold tags, linkages to FAI/AS9102 records and digital travelers.
- Traceability and genealogy: batch, heat, lot, and serial lineage; component composition for assemblies; recorded deviations tied back to specific work orders.
For regulated aerospace, increasing visibility usually implies more stringent expectations on data integrity, audit trails, and change control. Those must be factored into supplier selection and onboarding.
6. Respect brownfield realities and avoid full replacement assumptions
Execution visibility does not require replacing suppliers’ existing systems with your preferred stack. In many aerospace contexts, full replacement strategies fail because:
- Requalification and validation of new systems at a supplier can be prohibitively expensive and slow.
- Downtime to swap out MES/ERP threatens near‑term delivery commitments.
- Integrations with their own machines, QMS, and customer portals are entrenched and risky to disturb.
- Long equipment and program lifecycles favor incremental layering of connectivity over rip‑and‑replace.
Prioritized suppliers should be those where you can realistically coexist with existing MES/ERP/QMS by:
- Exchanging standard transaction and status data (PO, ASN, shipment, NCR) and selectively adding richer execution feeds where justified.
- Using portals or lightweight connectors that sit alongside current systems, rather than displacing them.
- Aligning on data definitions and IDs (PO, part, serial, lot, operation) so traceability holds across system boundaries.
7. A practical prioritization approach
Many OEMs find it useful to rank suppliers against a few core dimensions and then pick the first wave from the top of the list:
- Safety/compliance risk: flight-critical, special processes, configuration sensitivity.
- Program impact: single-source, long-lead, multi‑program linkage.
- Performance instability: chronic OTD issues, high NCR rates, frequent concessions.
- Digital readiness: usable electronic data, stable systems, willingness to integrate.
Suppliers that score high in risk and impact and at least moderate in digital readiness are the ones you should prioritize for deeper execution visibility. Lower‑risk, low‑impact, or digitally immature suppliers can be addressed in later waves with lighter‑weight approaches.
