CONTENT HISTORY LEAN PRINCIPLES TOYOTA PRODUCT DEVELOPMENT SYSTEM CASE STUDY CONCLUSION
HISTORY Lean introduce in Toyota pioneered by late chief engineer Taiichi Ohno and Sensei Shigeo Shingo. Idea is developed in 1940 and early 1950, and by early1960 they fully worked out the principles of lean production.
LEAN PRINCIPLE Specify value Identify the stream and eliminate waste Make the value flow Let the customer pull the process Pursue perfection
Toyota product development system Do not follow lean production in product development in same sense as in manufacturing processes. Toyota maintain functionally based organization with impressive integration Six organizational mechanisms Three primary social processes Three form of standard
CASE STUDY Single piece flow in NPI in Weston Aerospace Issue “lead time reduction in NPI” Problem 65 projects are carried out at one given time Eliminate batch and queue moving hem into single piece flow. Solution No of projects No of man hours Using flow chart identify the waste ,non value adding activity. Action
CONCLUSSION Lean to manufacturing processes have focused on improving the value added to non value added ratio by primarily reducing waste and not so much on increasing value. To be effective the design and development engineers and core support function need to focus on identifying and enhancing value.
QUESTIONS Do you think all of the 5 Lean Principles can be used in New Production Introduction - (1) Specify value; (2) Identify value stream and eliminate waste; (3) Make the value flow/Continuous stream; (4) Pull (On customer demand replenishment; and (5) Perfection/Need to be the best? Is it necessary for all the companies to follow the lean system theory? Why or Why not? Toyota developed lean and used it to develop into a major player, but they did not become a dominate player until they started moving away from lean practices. do you feel lean held Toyota back for several decades?
