Introduction
In today’s aerospace industry, supply chain performance plays a critical role in meeting customer expectations for quality, delivery, and production rate. With a significant proportion of components and materials sourced externally, maintaining visibility across the supply base is essential to ensuring program success.
To strengthen supply chain resilience and support long-term customer commitments, ST Engineering MRAS established a dedicated Supplier Performance Management (SPM) team to monitor supplier health, identify emerging risks, and drive continuous improvement across the supply chain.
The initiative has helped the company maintain industry-leading delivery performance while strengthening partnerships with suppliers across its network.
The Challenge
Aerospace supply chains are increasingly complex, with suppliers facing evolving production requirements, workforce pressures, material constraints, and rising demand.
While sourcing and fulfillment teams focus on near-term delivery requirements and purchase order execution, long-term supplier capability and capacity planning require a different level of oversight. Without proactive monitoring, issues such as declining delivery performance, capacity constraints, or process inefficiencies can go unnoticed until they begin to impact customer commitments.
ST Engineering MRAS recognized the need for a dedicated function capable of assessing supplier performance beyond immediate delivery requirements and identifying potential risks before they affect production.
Establishing a Dedicated Supplier Performance Management Team
To address this challenge, ST Engineering MRAS established a dedicated Supplier Performance Management team to provide a medium- and long-term view of supplier readiness and performance. Working across the company’s supplier network, the team evaluates whether suppliers have the capability, capacity, and operational stability required to support future program demand and contractual commitments.
The team conducts recurring monthly reviews across the supply base, assessing supplier performance against key operational metrics and identifying opportunities for improvement.
Suppliers are categorized according to business criticality, allowing resources to be focused on where they can deliver the greatest impact. This structured approach enables the team to prioritize high-risk suppliers while maintaining visibility across the broader supply chain.
Proactive Risk Identification and Supplier Support
A key differentiator of the Supplier Performance Management approach is its focus on proactive intervention. Rather than reacting to supply chain issues after they occur, the team works closely with suppliers to identify performance trends and address potential concerns before they impact production schedules. For example, if a supplier begins to experience a decline in on-Time delivery, the team can engage directly with the supplier to identify the root cause, develop corrective actions, and implement sustainable improvements.
When required, ST Engineering MRAS conducts on-site supplier engagements to gain deeper operational insight and support performance recovery efforts. This collaborative approach strengthens supplier relationships while helping ensure long-term program stability and customer confidence.
Delivering Measurable Results
The creation of a dedicated Supplier Performance Management function has significantly improved visibility across the supply chain and enabled faster response to emerging risks. By separating supplier performance oversight from day-to-day purchasing activities, the company has created greater focus on long-term supplier health and continuous improvement.
Since establishing the dedicated SPM team, ST Engineering MRAS has consistently maintained on-time delivery performance of 95% or greater across standard lead-time contracts, supporting customer schedules and production requirements.
Conclusion
ST Engineering MRAS’s Supplier Performance Management approach demonstrates the value of proactive supplier engagement, data-driven decision-making, and long-term partnership development. By investing in dedicated supplier performance oversight, the company has strengthened supply chain resilience, improved operational visibility, and enhanced its ability to deliver consistent results for customers.
As aerospace production rates continue to increase, proactive supplier management will remain a critical element of maintaining quality, reliability, and program success across the supply chain.
