Strengthening the Supply Chain through Dual Sourcing and Cost Reduction

Client Challenge

• Mubea Aerostructures faced critical structural challenges in its upstream supply chain:
• Delivery performance and quality from key suppliers were below expectations
• A high dependency on single-source suppliers across the entire direct spend volume posed significant supply risk
• There was no experience in making Make-or-Buy decisions, and potential for insourcing critical components remained untapped
• The company was caught in a “sandwich” position – pressured by price-sensitive clients and cost-driven suppliers

• Margin expectations could not be met under the existing setup

   

To stay competitive, Mubea needed to rethink its sourcing model and improve resilience without compromising on quality. 

H&Z Approach

H&Z took a strategic and hands-on approach to transform Mubea’s supply chain setup:

• Assessed the capabilities, capacities, technologies and cost structures of both internal and external suppliers
• Evaluated opportunities for Make-or-Buy, enabling an informed and fact-based shift toward dual sourcing
• Supported supplier scouting and development following the selection of suitable partners
• Facilitated the relocation and Transfer of Work (ToW) in close alignment with Airbus and across international operations

• Developed a clear and transparent decision-making template to guide implementation

   

This approach not only addressed current bottlenecks but built a foundation for long-term supply chain stability. 

Results

The collaboration led to tangible and sustainable improvements:

• Improved delivery performance, both in terms of on-time and in-spec deliveries
• Reduced cost of poor quality, with fewer delivery failures and quality issues
• Lower material costs, achieved through competitive dual sourcing and targeted supplier development
• Reduced supply risk, thanks to a diversified supplier base and clear Make-or-Buy logic
• Build-up of internal know-how, enabling better strategic sourcing decisions in the future

• A scalable decision framework, supporting future relocations and sourcing initiatives

   

Mubea is now better positioned to navigate market dynamics with a more flexible, cost-effective and reliable supply chain.
