This case study examines a Lean Manufacturing initiative involving three aerospace suppliers - Haynes International Ltd, Precision Parts Engineering Ltd, and Merc Engineering Ltd - and their customer, Unison Engine Components. The objective was to reduce costs and improve delivery performance to combat low-cost competitors. A Lean consultant introduced tools like 5S, improved layouts, kanban systems and visual controls. Early results included a 15-22% improvement in on-time delivery, better awareness of customer needs, and more efficient operations.
