The production system of the company is built on application of Just-In-Time and Jidoka
Many of the ideas are encapsulated in a Lean management vocabulary of "maybe 15" Japanese words--"walking the gemba," or evaluating a process by watching it being done; drawing up flow charts, conducting root cause analyses and applying other continuous quality improvement techniques ceaselessly to find muda, or waste; equipping technology and empowering people at every level, without fear of repercussions, to interrupt questionable processes before harm results--a fundamental concept called jidoka
The Toyota Production System operates with the expression Jidoka
, known as "automation with a human touch".
It is a management concept based on two key principles -- Jidoka
, which is translated as "automation with a human touch," and the Just-in-Time system, according to Dr.
Por ejemplo: el SMED o Single Minute Exchange of Die, desarrollada por Shigeo Shingo (1991, 2003), permite reducir drasticamente el tiempo de preparacion de un cambio de referencia; el sistema de planificacion Kanban, desarrollado por Taiichi Ohno (1991), sirve para controlar la cadena logistica desde un punto de vista de la produccion siguiendo un enfoque pull; el Jidoka
(Ohno, 1991), o automatizacion con un toque humano, permite que los procesos tengan su propio autocontrol de calidad solucionando los problemas en el momento que se producen e impidiendo que estos se propaguen aguas abajo en la cadena productiva; etc.
Visual aids that can support this effort include a visual scoreboard, Jidoka
lights, work areas designated by taped or painted lines, colorcoded ESD workspaces and Kanban squares.
Some of much practiced tools are Continuous Quality Improvement (CQI) methodologies, including Six Sigma, Value Stream Analysis, Jidoka
, Kiazen and Lean6.
If we represent the tools used in the procedures of Lean concept design as a house--a firm creation of human work, and if we should explain the Lean concept as parts of the house, then the supporting pillars would be Just-In-Time and Jidoka
(or making quality at source).
