What is poka-yoke with example?
Poka-Yoke, also known as mistake-proofing, is a technique for avoiding simple human errors at work. Another example of Poka-Yoke device – many elevators are equipped with an electric eye to prevent doors from shutting on people. They are also equipped with sensors and alarms to prevent operation when overloaded.
What are the three types of poka-yoke?
There are three types poka-yoke systems that can be used to fail-safe the server: task poka-yokes, treatment poka-yokes, and tangible poka-yokes.
What is poka-yoke mechanism explain it briefly?
Poka-yoke (ポカヨケ, [poka joke]) is a Japanese term that means “mistake-proofing” or “inadvertent error prevention”. A poka-yoke is any mechanism in a process that helps an equipment operator avoid (yokeru) mistakes (poka) defects by preventing, correcting, or drawing attention to human errors as they occur.
What is meant by poka-yoke?
Poka-Yoke is any mechanism in a Lean manufacturing process that helps to avoid mistakes. Its purpose is to eliminate product defects by preventing, correcting, or drawing attention to human errors as they occur.
Where is Poka Yoke used?
Here are 10 examples of Poka-Yoke in our everyday lives:
- Car safety features.
- Microwaves, washing machines, dishwashers, and other household appliances.
- Elevators & garage doors.

What is difference between Kaizen and Poka Yoke?
Kaizen is an approach adopted by everyone in the organization with the belief that over time, these small changes will lead to major improvements over time. Poka Yoke: Also a Japanese term, Poka Yoke translates to mean mistake-proofing.
How do you prove a mistake?
Mistake Proofing Procedure Obtain or create a flowchart of the process. Review each step, thinking about where and when human errors are likely to occur. For each potential error, work back through the process to find its source. For each error, think of potential ways to make it impossible for the error to occur.
What is Poka-Yoke in TQM?
Poka-Yoke is a process improvement designed to prevent a specific defect from occurring. It is a process improvement system that prevents personal injury, promotes job safety and prevents faulty products and machine damage. Poka-yokes are mechanisms used to mistake proof an entire process.
What Is mistake proofing in Six Sigma?
Mistake-proofing, or Poka-Yoke (pronounced POH-kuh YOH-kay) as it’s known in Japan, is an action you take in Six Sigma to remove or significantly lower the opportunity for an error or to make the error so obvious that allowing it to reach the customer is almost impossible.

What are the types of poka-yoke?
There are two types of poka-yoke: control and warning.
- Control: The goal is to make it mechanically impossible for mistakes to be made.
- Warning: Color or sound is used to alert operators that they are about to make a mistake.
What is net available time per day?
Net available time is the amount of time available for work to be done. This excludes break times and any expected stoppage time (for example scheduled maintenance, team briefings, etc.). Example: Customer demand can still be met by adjusting daily working time, reducing down times on machines, and so on.
What are the three error proofing categories?
Shigeo Shingo coined three types of poka-yokes: Contact method – identifies defects by testing product characteristics. Fixed-value – a specific number of movements every time. Sequence method – determines if procedure were followed.
Which of the following is an example of error proofing?
Other examples of error proofing in vehicles: Headlights shut off automatically when left on or audible alert triggered. Car doors do not lock when keys left inside. Lights on dashboard appear when tire pressure is low, doors are left open, seat belts are not put on, turn signal left on, etc.
