Lean is a business and process optimization philosophy based on 5 principles: define value, map the value stream, make value flow, establish pull and continuously improve to perfection. Applying lean reduces waste and enhances people creativity and engagement.
It was first applied in car manufacturing at Toyota (Japanese car manufacturer) as TPS (Toyota Production System) and subsequently spread to all business sectors, including industrial services, financial services, logistics, human resources, public services, and even in household activities.
Lean methodology may be successfully applied in a garage workshop providing significant processes streamlining and hence reduced time for repair (TFR).
