Jidoka
one of the two main pillars of TPS. It refers to the ability to stop production lines, by man or machine, in the event of problems such as equipment malfunction, quality issues, or late work. Jidoka helps prevent the passing of defects, helps identify and correct problem areas using localization and isolation, and makes it possible to “build” quality at the production process.

Jishuken
management driven kaizen activity where management members identify areas in need of continuous improvement and spread information through the organization to stimulate kaizen activity.

Juran
Dr. Juran first began developing a philosophy of quality in 1926 when he started working for the quality inspections division at Western Electric. He theorized that the field really depended on human factors, especially the work of managers, and that quality problems should be solved systemically. Juran first became well known in the quality field in the US as the editor of the Quality Control Handbook (1951) and later for his paper introducing the quality trilogy - planning, control and improvement. He developed the Pareto principle, named after the Italian economist Vilfredo Pareto, which observes that 80% of the problems in management arise from 20% of causes.

Just-In-Time
one of the two main pillars of TPS. It refers to the manufacturing and conveyance of only what is needed, when it is needed, and in the amount needed. It is built upon three basic principles: the pull system, continuous flow processing and takt time.
