TPS

Toyota Production System

Lean Manufacturing is sometimes called the Toyota Production System (TPS) because Toyota Motor Company’s Eiji Toyoda and Taiichui Ohno are given credit for its approach and innovations.

Based on two philosophies:

1. Elimination of waste 

2. Respect for people

Toyota production System four rules:

1.All work shall be highly specified as to content, sequence, timing, and outcome.

2.Every customer-supplier connection must be direct, and there must be an unambiguous yes-or-no way to send requests and receive responses.

3.The pathway for every product and service must be simple and direct.

4.Any improvement must be made in accordance with the scientific method, under the guidance of a teacher, at the lowest possible level in the organization. 

5 S :

• The 5S‘s are simple but effective methods to organise the workplace.
• The methodology does however, go beyond this simple concept, and is concerned with making orderly and standardized operations the norm, rather than the exception.
• Posters bearing the 5S terms can be found on the walls of Japanese plants, and are a visual aid to organisational management

Japanese Origins:

• Seiri (Sort) This requires the classifying of items into two categories, necessary and unnecessary, and disregarding or removing the latter.
• 
  
• Seiton (Straighten) Once Seiri has been carried out Seiton is implemented to classify by use, and arrange items to minimise search time and effort. The items left should have a designated area, with specified maximum levels of inventory for that area.
• 
  
• Seison (Shine) Seison means cleaning the working environment. It can help in the spotting of potential problems as well as reducing the risk of fire/injury by cleaning away the potential causes of accidents.
• 
  
• Seiketsu (Systematise) Seiketsu means keeping one's person clean, by such means as wearing proper working clothes, safety glasses, gloves and shoes, as well as maintaining a clean healthy working environment. It can also be viewed as the continuation of the work carried out in Seiri, Seiton, and Seison.
• 
  
• Shitsuke  (Sustain) Shitsuke means self-discipline. The 5 S‘s may be viewed as a philosophy, with employees following established and agreed upon rules at each step. By the time they arrive at Shitsuke they will have developed the discipline to follow the 5 S‘s in their daily work.
