Jidoka is a technique to provide machines and operators with the ability to detect when an abnormal condition has occurred and immediately stop the work. Also known as autonomation, meaning "automation with human intelligence", Jidoka is the tool of built-in quality and supports just-in-time production. With an effective Jidoka system in place, companies can ensure that defects are not passed on to the customer, equipment breakdown is prevented and operators can work on multiple machines instead of wasting their time watching them.

In this training presentation, you will learn the key concept and principles of Jidoka, understand the tools and the four-step process of Jidoka, as well as gain insights on developing an effective Jidoka system.

LEARNING OBJECTIVES:

1. Understand the key concept and principles of Jidoka

  4. 4. © Operational Excellence Consulting. All rights reserved. 4 Introduction to Jidoka Jidoka is a technique to provide machines and operators with the ability to detect when an abnormal condition has occurred and immediately stop the work. Jidoka is also known as autonomation, meaning “automation with human intelligence” or “intelligent machines.”
  5. 5. © Operational Excellence Consulting. All rights reserved. 5 Jidoka is one of the two pillars of the Toyota Production System along with Just-In-Time Stability Heijunka Standardized Work Kaizen Just-In-Time • Continuous flow • Takt time • Pull system • Flexible workforce Jidoka • Separate man & machine work • Abnormality Identification • Poka yoke Goals: highest quality, lowest cost, shortest lead times Involvement Focuses on Quality and Prevention
  6. 6. © Operational Excellence Consulting. All rights reserved. 6 Jidoka – The Tool of Built-in Quality  Jidoka allows the operation to have a build-in quality at each step of a process, so the operator does not have to “watch” the machine or the operation  Jidoka is based on:  Don’t accept defects  Don’t make defects  Don’t pass on defects
  7. 7. © Operational Excellence Consulting. All rights reserved. 7 Principles of Jidoka  Separate man’s work from machine’s work  Man’s work and machine’s work are separated for better efficiency  “Stop the line and fix the problem”  Stop and notify of an abnormality - never let a defect pass to the next station  Build-in quality at each process  Attacks waste at the source  Develop a mindset of doing it right the first time  Prevention  Analyze the root causes, implement countermeasures and improve continuously

  9. 9. © Operational Excellence Consulting. All rights reserved. 9 Concept of Jidoka Source: Toyota A machine detects a problem and communicates it Improvements incorporated into the standard workflow Manager/supervisor removes cause of the problem The line is stopped A situation deviates from the normal workflow Daily improvements 1 2 4 5 3
  10. 10. © Operational Excellence Consulting. All rights reserved. 10 Benefits of Practicing Jidoka  Defects are not passed on to the next process (the “Customer”)  Equipment breakdown is prevented because problems and their causes become immediately apparent  Machine work is separated from Human work so that team members can operate multiple machines (savings in manpower)
  11. 11. © Operational Excellence Consulting. All rights reserved. 11 Tools of Jidoka  Andon  Andon cord  Fixed-position stop  Poke-yoke  Sensors
  12. 12. © Operational Excellence Consulting. All rights reserved. 12 What is Andon?  Andon is the Japanese word for “paper lantern”  Refers to any visual display that shows status information  Often combined with an audible signal such as an alarm  Andons are erected to signal when the line is stopped for defects, or difficulties on the line, and as signals for replenishments for parts #1 #2 #3 #4 ANDON BOARD Green = Normal Operation Yellow = Call for Help Red = Line is Down
  13. 13. © Operational Excellence Consulting. All rights reserved. 13 Andon Cord  Andon Cord – a mechanism, usually a rope, that a worker may pull to signal the need for assistance and which will stop the line if the problem is not fixed under takt time
  14. 14. © Operational Excellence Consulting. All rights reserved. 14 Fixed-Position Stop  Fixed-Position Stop – a position on the assembly line where a zone process is completed. It is at these positions that the line will stop should an abnormality be not corrected on time – at the end of takt time. Source: Adapted from Lean Enterprise Institute Fixed-Position Stop
  15. 15. © Operational Excellence Consulting. All rights reserved. 15 Activity: Andon  In your respective groups, discuss when and where andons can potentially be erected in your work areas to signal the following conditions: 1. When the line is stopped for defects 2. When difficulties are encountered on the line 3. When replenishments for parts are required  List your ideas on the flip chart.  Present your ideas to the class. Time: 10 mins
  16. 16. © Operational Excellence Consulting. All rights reserved. 16 What is Poka-Yoke?  Poka-yoke is a Japanese term which means “mistake- proofing” or “error-proofing”  Poka-yoke refers to techniques using low-cost devices or innovations that make it impossible to make mistakes  Poka-yoke helps people and processes work right the first time
  17. 17. © Operational Excellence Consulting. All rights reserved. 17 Conditions for Poka-Yoke  The goal is zero defects  Design must be based on actual worksite conditions  Devices must be economical  Devices must be simple with long life and low maintenance
  18. 18. © Operational Excellence Consulting. All rights reserved. 18 Three Rules of Poka-Yoke 1. Don’t wait for the perfect poka-yoke. Do it now! 2. If your poka-yoke idea has better than 50% chance to succeed… Do it! 3. Do it now... improve later!
