Editing Toyota Production System (section)

==Concept==
Toyota Motor Corporation published an official description of TPS for the first time in 1992; this booklet was revised in 1998.<ref>Toyota Motor Corporation: ''The Toyota Production System – Leaner manufacturing for a greener planet''; TMC, Public Affairs Division, Tokyo, 1998</ref> In the foreword it was said: "The TPS is a framework for conserving resources by eliminating waste. People who participate in the system learn to identify expenditures of material, effort and time that do not generate value for customers and furthermore we have avoided a 'how-to' approach. The booklet is not a manual. Rather it is an overview of the concepts, that underlie our production system. It is a reminder that lasting gains in productivity and quality are possible whenever and wherever management and employees are united in a commitment to positive change". TPS is grounded on two main conceptual pillars:
# ''[[Just-in-time manufacturing|Just-in-time]]''<ref>ibidem,  p. 11 ff.</ref> – meaning "Making only what is needed, only when it is needed, and only in the amount that is needed"
# ''[[Jidoka]]''<ref>ibidem,  p. 25 ff.</ref> –  (Autonomation) meaning "Automation with a human touch"

Toyota has developed various tools to transfer these concepts into practice and apply them to specific requirements and conditions in the company and business.
