Lean Transformation Boosts Productivity 20% in Luxury Automotive

A luxury automotive manufacturer faced significant challenges as it attempted to ramp up a second vehicle series, introduce a third on the same assembly line, and absorb a rapid volume increase. EFESO deployed a structured, multi-phase Lean Transformation that increased throughput, stabilized quality, and improved productivity across all series.

The Challenge

The manufacturer needed to stabilize and accelerate production while managing increasing complexity across multiple vehicle series:

  • Ramp-up issues for the second vehicle series entering the production line
  • Introduction of a third series on the same assembly line
  • Doubling of production volumes in only a few months
  • Need to improve productivity, stabilize quality, and rebalance processes across high-variant models

Real Results Achieved Together

EFESO’s structured implementation, combining KPI-focused execution, process redesign workshops, and deep waste analysis—unlocked major performance gains across productivity, volume, and quality.

Our Approach

EFESO supported the automotive client by:

  • Taking a structured and parallel approach for Lean Transformation with early manager involvement including:
    • 3-week analysis and concept phases
    • 6-week implementation phase
    • 8-week light support phase
  • Ensuring there was focus on KPIs per division right from the start
    • Hours Per Unit (HPU), Right First Time (RFT), Defects Per Vehicle (DPV)
  • Recording comprehensive video of process sequences and joint waste analysis for 2 series model variants
  • Improving process and design of new series in the form of 3P (Pre-Production-Planning)-light workshops
  • Consolidating Yamazumi boards of all processes and parallel line balancing of the three series

Overall, a targeted implementation with prioritization of metrics.
