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

Operating model refinement and commercial focus to deliver a step change in business performance

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
  • Despite repeated calls by Group to improve, the business continuously failed to meet performance expectations on revenue growth, profit margin and free cash flow
  • The business was suffering from an overly-layered and siloed organisation structure, with burdensome management processes and lacking commercial focus
  • The underlying issues were structural and an absence of effective performance management, wrongly being justified because business discipline would stifle creativity and innovation

  • Implemented over a 12-month period working alongside the business unit leadership with a structured plan;
    • A new leadership team established, with stronger governance processes,  metrics, and proactive staff engagement
    • Simplified the operating model and aligned capabilities to market needs
    • Re-framed value propositions and initiated the move into critical national infrastructure
    • Implemented resource management to drive productivity uplift
    • Implemented new mentoring and HR processes to underpin talent management
  • Supported post-implementation by refreshing the plan

The results

  • 29% revenue uplift (versus budget target)
  • 18% Return on Sales achieved versus a 15% target for the financial year
  • 90% improvement in business cash flow
  • 10% points increase in Engineer productivity, with a continued increase to 74% utilisation in year 2, and climbing
  • Transformed the operating model and business culture to be customer and commercially focused
