Shigeo Shingo
Who invented poka-yoke?
Shigeo ShingoPoka-yoke is a lean manufacturing tool that refers to “mistake-proofing” or “error-proofing” a process. It was originally coined by Shigeo Shingo in the 1960s and implemented at Toyota as part of the Toyota Production System (TPS).
What is poka-yoke Japanese?
Mistake proofing, or its Japanese equivalent poka-yoke (pronounced PO-ka yo-KAY), is the use of any automatic device or method that either makes it impossible for an error to occur or makes the error immediately obvious once it has occurred. It is a common process analysis tool.
What was the main idea behind the development of poka-yoke?
A poka-yoke is any mechanism in a process that helps an equipment operator avoid (yokeru) mistakes (poka) and defects by preventing, correcting, or drawing attention to human errors as they occur. The concept was formalized, and the term adopted, by Shigeo Shingo as part of the Toyota Production System.
What is difference between Kaizen and poka-yoke?
Brief description of Kaizen (Continuous Improvement), PokaYoke (Fool Proofing) and 5S. Brief description of Kaizen (Continuous Improvement), PokaYoke (Fool Proofing) and 5S.
What are the 3 types of poka-yoke?
Poka-Yoke devices consist of three effective methods to ensure detection and prevention of mistakes: 1. Contact method 2. Fixed-Value method 3. Motion-step method; Each method can be used in Control approach or Warning approach.
What are the 7 Mudas?
Under the lean manufacturing system, seven wastes are identified: overproduction, inventory, motion, defects, over-processing, waiting, and transport.
What are the 3 levels of mistake-proofing?
No matter what title you choose, the fundamental purpose of all three is to prevent errors that cause defects, notify the operator if an error has occurred or prevent the defect from moving to the next step in the process or reaching the customer.
What is the benefit of poka-yoke?
Poka-yoke provides many benefits to manufacturing processes, the foremost being an improvement in overall quality control. By integrating poka-yoke inline, mistakes are either prevented or caught shortly after they happen. This prevents defective products from making it to the end of the process.
How poka-yoke reduces waste?
Poka-yoke is one of several Lean manufacturing tools designed to help organizations eliminate waste, streamline processes, and increase efficiency. Specifically, poka-yoke tries to achieve zero defects by preventing and eliminating errors.
Why it is called 6 Sigma?
It's called Six Sigma because the term sigma refers to one standard deviation in a data set. The idea is that six such deviations should occur before the process results in a defect. When a process achieves Six Sigma, it reaches a point where only 3.4 errors per one million process events result in a defect.
What is poka-yoke in 5S?
Poka-Yoke translates as “prevention of carelessness”. If production systems are planned in line with Poka-Yoke methodology, staff are less likely to make inadvertent mistakes or random errors.
What is poka-yoke in TPM?
In Japanese, the term means "mistake-proofing". Yoke is literally "to avoid," and poka translates as "inadvertent errors." Poka yoke, therefore, is a technique for building mechanisms into a process that prevent people from making mistakes.
What are the 5 elements of kaizen?

What are the 4 main kaizen principles?
The 4 Types of KaizenWhat you will learn:Kaizen Teian: Bottom-Up Improvement.Kaizen Events: Defined Improvements.Kaikaku: Radical Change.Kakushin: Break-through Innovation.Finding The Right Tool.
How is poka-yoke implemented?
To implement poka-yoke correctly, we need to look internally to see the errors and failures in our operations, rather than others' processes. Only then, will we begin to understand the concept of poka-yoke. Once we start to perfect our processes, we can begin to understand and look at using poka-yoke correctly.

· Poka-yoke (a Japanese term roughly “mistake proofing”) is one of the techniques used to build quality into lean processes, be they for manufacturing workflows or otherwise. The idea is that every process can be engineered to inherently prevent mistakes either through re-engineering tasks to suit a standard format or by including specific measures which make sure that …

ANSI/ASME A13.1 Pipe Marking Standard. Pipe color-coding is not a complicated process, especially if industry standards are used. There are many standards out there from a variety of sources, but by far the most popular is the ANSI /ASME A13.1 standard. This standard explains colors, text, size, and placement of pipe marking labels.
