The main goal of kaizen is the elimination of non-value-added activities (waste) through the implementation of one-piece flow, working to takt time, and instituting a pull system. The mantra is to manufacture only what is needed by the customer, when it is needed, and in the quantities ordered. Kaizen has been shown to collapse lead times, dramatically reduce work in process, and reduce scrap and defects while minimizing the need for capital expenditures. Its successful results across industry are real, proven, documented, and confirmed!
