Concepts of Lean
The practical expression of Toyota's people and customer-oriented philosophy is known as LEAN Manufacturing or originally ‘The Toyota Production System’ (TPS). This is not a rigid company-imposed procedure but a set of principles that have been proven in day-to-day practice over many years.
Lean has three desired outcomes:

1. To provide the customer with the highest quality products, at the lowest possible cost, in a timely manner within the shortest possible lead time.
2. To provide employees with work satisfaction, job security and fair treatment
3. To give the companies flexibility to respond to the market demand, achieve profit through cost reduction activities and long-term prosperity.
