In daily life, we make lots of errors and then regret it. Errors are a natural part of human behavior. But sometimes, small errors can be dangerous and sometimes result in serious injuries or accidents. Can we avoid making such errors? That is where Poka Yoke can help.
Let's look at some practical ways to prevent such errors from happening in this article.
Before we understand Poka Yoke or Error Proofing, we must know what are errors.
An error is an action that is inaccurate or incorrect. Errors can be caused by bad judgment, ignorance, inattention, carelessness, or forgetfulness. Errors can result in failure, deviation from intended performance or behavior, or a departure from what should be done.
Poka Yoke Meaning
Poka Yoke is a lean manufacturing tool that refers to error-proofing or mistake-proofing.
Poka Yoke Definition
Poka Yoke (pronounced Poh-kah YOH-kay) is a Japanese concept that means error-proofing. It's a way to approach a process such that you may foresee potential problems before they arise.
The term Poka Yoke was originally coined by Shigeo Shingo in the 1960s and implemented at Toyota as part of the Toyota Production System (TPS).
Poka-yoke is also present in our everyday lives, although many examples are so mundane that we often don’t realize they are there.
Poka Yoke Examples in Daily Life
1. ATM Machines are designed in a way that the cards cannot be accepted if they are inserted incorrectly or incorrect PIN is entered.
2. Files are easy to be placed with incorrect sequence. By writing a number or making a mark that tells the correct sequence can avoid this sequence error.
3. USB pins won't fit in if inserted incorrectly or upside down. This prevents it from damaging the circuitry.
4. In case the drain hole is clogged, many sinks contain a hole just below the pipe that keeps water from overflowing.
5. Sim cards have a cut in one corner to ensure there is one correct way it can be placed inside your phone and prevent it being inserted incorrectly.
6. The majority of elevators have sensors that stop the doors from shutting if something or someone is in the way. This feature is also present in automatic garage doors, subway doors, and other doors. Additionally, a lot of elevators beep and stop working if the weight restriction is exceeded.
7. Hotel keys are also a perfect example of Poke Yoke. It prevents lights from being on when no one is in the room.
8. Many plugs, including USB chargers plugs have 3-pin plugs, that are built to fit into outlets only in a specific direction. The earth pin is usually wider and longer so it's necessary to connect the plug to the socket correctly. This is a common example of the "contact" approach of error-proofing, which takes advantage of the physical characteristics of the object to stop mistakes from occurring.
