Aerospace Supply Chain: Lack of Visibility Beyond Tier-1 Suppliers

Aerospace Supply Chain: Lack of Visibility Beyond Tier-1 Suppliers

Supply chain efficiency is one of the major competitive advantages for an aerospace company. Supply chain performance measurement is key to understanding any underlying concerns, uncovering the causes, eradicating repetitive problems, and improving and sustaining its efficiency – at pace.

With a complex and multi-tiered supply chain, involving numerous suppliers beyond the immediate Tier-1 level; visibility is crucial for maintaining high standards of quality, ensuring timely production, and mitigating risks. Take Airbus for example: with 80% procurement of components bought from external suppliers. A reliable supply chain is an absolute must for at least two reasons: firstly, to achieve industrial ramp-up to meet market demand; secondly, to secure new industrial programmes such as A330 development, A350 ramp-up, and A320neo entry into service. With this scale of challenge, Airbus Procurement has the objective to eradicate issues and disruptions by improving three main processes: deliver on quality, time and cost; contribute to operational efficiency; and drive suppliers’ continuous improvement.

While Tier-1 suppliers are often closely monitored and managed, and given reported difficulties in obtaining critical items such as aircraft structural components and interior cabin equipment. These supply chain challenges are not just a consequence of the COVID-19 pandemic but are also influenced by ongoing geopolitical tensions and economic uncertainties. Therefore, the lack of visibility beyond these immediate suppliers can pose significant threats to the entire supply chain. Business leaders aim to address these challenges to secure their operations and maintain competitive advantage. Understanding and mitigating these risks is key to ensuring uninterrupted production, maintaining quality standards, and safeguarding against unforeseen disruptions.

 

The Critical Role of Supply Chain Visibility

Visibility in the supply chain means having real-time, comprehensive insight into the activities, processes, and performance of all suppliers, from Tier-1 down to the raw material providers. In aerospace, where precision and reliability are paramount, any blind spots can lead to severe consequences, including production delays, cost overruns, and compromised safety. Visibility beyond Tier-1 suppliers can highlight potential risks and enable proactive management of the challenges before they escalate.

 

Risks of Limited Visibility Beyond Tier-1

1. Quality Control Issues

Lower-tier suppliers may not adhere to the stringent quality standards required in aerospace manufacturing. Without proper oversight, substandard components can infiltrate the supply chain, resulting in costly rework, production delays, and potential safety hazards.

2. Supply Chain Disruptions

Tier-2 and Tier-3 suppliers often operate with less financial stability and capacity compared to Tier-1 suppliers. This makes them more susceptible to disruptions, which can ripple through the entire supply chain, causing significant production delays.

3. Compliance and Regulatory Challenges

Aerospace manufacturers must comply with numerous regulatory standards. Lack of visibility into the practices of lower-tier suppliers can lead to inadvertent non-compliance, risking legal penalties and damaging the company’s reputation.

4. Hidden Costs and Inefficiencies

Inefficiencies and hidden costs (in what is known as ‘hidden factory’) within the lower tiers of the supply chain, which can accumulate, eroding profit margins. These can stem from poor planning, poor material & information flow, excessive scrap, inefficient processes, poor factory layout – leading to wastes such as excessive inventory levels, over-processing, unnecessary handling, and high transport costs.

Actionable Strategies to Enhance Visibility

1. Strengthen Supplier Relationships

Building robust relationships with Tier-1 suppliers is essential, but extending these relationships to include lower-tier suppliers is equally important. Encouraging Tier-1 suppliers to foster similar transparency and communication with their own suppliers can create a more cohesive and visible supply chain.

Actionable Advice: Organise regular meetings and joint improvement initiatives with Tier-1 suppliers to discuss the importance of extended visibility. Foster a culture of collaboration and trust throughout the supply chain.

2. Leverage Advanced Technologies

Technological solutions such as blockchain, Internet of Things (IoT), and advanced analytics can provide real-time visibility beyond Tier-1 suppliers.

These technologies enable tracking of components and materials from their origin through to the final product.

Actionable Advice: Invest in comprehensive supply chain management software that integrates with suppliers’ systems. Use IoT sensors for real-time tracking and blockchain for secure, transparent record-keeping. Encourage suppliers to integrate these technologies to ensure seamless data flow and tracking.

3. Implement Regular Audits and Assessments

Conducting regular audits of all suppliers, not just Tier-1, can help identify risks and ensure compliance with quality and regulatory standards.

Actionable Advice: Develop a rigorous audit programme that includes Tier-2 and Tier-3 suppliers. Use audit findings to drive continuous improvement and ensure adherence to standards.

4. Encourage Transparency and Open Communication

A transparent supply chain relies on open communication between all parties. Ensuring that lower-tier suppliers are committed to transparency can significantly reduce risks.

Actionable Advice: Establish clear communication protocols and provide training to suppliers on the importance of transparency. Encourage suppliers to report challenges promptly and share information openly.

5. Leverage Supplier Performance Metrics

Using key performance indicators (KPIs) across strategically positioned performance boards, within the supplier facility to monitor performance, can help identify trends and potential challenges before they escalate or impact production. They provide real-time feedback to supplier workforce and management, fostering accountability and motivating continuous improvement. This includes tracking metrics for quality, delivery times, and compliance. Remember: Good KPIs will tell you what’s happening; Great KPIs will give you insights that drive actions.

Actionable Advice: Define relevant KPIs for quality, delivery, and compliance; utilising a balance of leading and lagging KPI’s. Use colour coding to highlight areas needing attention, making it easy to identify and address abnormalities quickly – and regularly review these metrics to foster engagement with suppliers – addressing any performance challenges and concerns promptly to enable corrective action implementation.

Conclusion

The lack of visibility beyond Tier-1 suppliers in the aerospace supply chain poses significant risks to production, quality, and compliance. By strengthening supplier relationships, leveraging advanced technologies, implementing regular audits, encouraging transparency, and leveraging performance metrics, business leaders can enhance supply chain visibility and mitigate these risks. Proactive management and continuous improvement will ensure a resilient and efficient supply chain, securing long-term success and competitiveness in the aerospace industry.
