What is the concept of poka-yoke? 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.

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 poka-yoke give 3 examples? Many household appliances such as microwaves, washing machines and dryers, and dishwashers have mechanisms that prevent them from running when the door is open. These are examples of control functions, which prevent the process from running until required conditions (i.e. the door being closed) have been met.

What are benefits of poka-yoke?

Chapter Two: Benefits of Poka-Yoke
  • Reducing time spent on training. Since workers won’t need to look out for as many problems, you won’t need to spend as much time training them on these issues.

What are the levels of poka-yoke?

It has 3 levels:
  • Firstly, there should be an elimination of spills, leaks, and losses at the source. Alternatively, it could also assist in the prevention of a mistake.
  • Secondly, the detection of a loss or mistake as it occurs is crucial.
  • Lastly, prevention is salient.

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.
