Lean value chain analysis and design for global precision engineering products leader in aerospace industry
The issue
- A complex multi-stage casting, machining and coating operation manufacturing precision components for the aerospace industry
- Underperforming organisation and low levels of ownership for improvement
- Extremely low velocity through the process, with poor yields and excessive scrap
- High inventories of work in progress and finished goods
- Production measures encouraging over-production
- Silo mentality in operations exacerbating the WIP situation
- Disaffected workforce with little interest in driving continuous improvement and no effective performance management in place
Solution
- Analyse the current situation to articulate the operational improvement potential (yield uplift and inventory reduction)
- Create the business case for change (P&L and cash impact)
- Design a pilot to create an integrated supply chain for the largest volume product including suppliers and JV partners
- Detail design of a pull model and elimination of WIP stages along the entire supply chain
- Re-design of the layout and organisation to separate ‘dirty’ and ‘clean’ operations to reduce rework
- Launch of a continuous improvement approach within the shop floor to tackle scrap, rework and productivity issues
- Design and introduction of a cascaded performance management framework

The results
- 40% reduction in inventory identified through WIP elimination
- The feasibility of a 50% reduction in production lead time confirmed
- 10 percentage-point improvement in yield performance from closer process control
- Plan to deliver £5m savings in-year agreed
- Changes to ways of working implemented in pilot cells with Lean work-flow approach trialled
- Programme of Lean training and continuous improvement projects implemented
- New KPIs are being used to drive the performance of the value chain in place of traditional cost absorption metrics

The issue
- A subsidiary of a global defence company, providing technology-based R&D solutions and advisory services to government and defence organisations and private sector companies at the cutting edge of secure communications and cyber warfare
