How does poka-yoke work?
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 poka-yoke methods?
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 is poka-yoke with example?
A great example of poka-yoke is when you have to put your car in park and push in the brake before you can start it. This is so that you don't start the car and immediately begin rolling by accident. A simple step added to the process of starting your car makes this costly mistake practically impossible.
How does poka-yoke help prevent such mistakes?
Poka-Yoke ensures that the right conditions exist before a process step is executed, and thus preventing defects from occurring in the first place. Where this is not possible, Poka-Yoke performs a detective function, eliminating defects in the process as early as possible.
What are the 3 levels of mistake proofing?
Simplify the step by making the correct action simpler to perform than the error. Eliminate the step by asking if this step required and does it add value. Error Proof the step by making this step impossible to error.
How does a poka-yoke improve quality?
Poka Yoke ensures that the right conditions exist before a process step is executed, and this prevents defects, mistakes, or accidents from occurring in the first place. Where this isn't possible, Poka Yoke performs a detective function, eliminating defects in the process as early as possible.
Is Poka yoke a Six Sigma tool?
Poka-yoke (poh-kah yoh-keh) is a tool used in Lean and Six Sigma to identify steps in a process where an error is likely to occur, allowing managers to make changes to prevent them. It's a useful tool that applies to any operation in any industry where errors can occur.
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 5S poka-yoke?
5S and Poka-Yoke are two highly effective methods of visual management. As we've already shown in the first part of our series, visual management plays an extremely important role in lean production, with the use of optical signals enabling staff without prior knowledge to detect problems straight away.
How does poka-yoke improve quality?
Poka Yoke ensures that the right conditions exist before a process step is executed, and this prevents defects, mistakes, or accidents from occurring in the first place. Where this isn't possible, Poka Yoke performs a detective function, eliminating defects in the process as early as possible.
What is poka-yoke in Six Sigma?
The word Poka means 'inadvertent mistake' and Yoke means 'prevention'. It's not about finding or correcting mistakes in a process but preventing them from ever being made. Poka Yoke is used to design processes so that defects are almost impossible.
What is the difference between poka-yoke and FMEA?
How is FMEA different from Poka-Yoke? While FMEA is an analysis that identifies root causes of product failures using a top-down analysis, Poka-Yoke is a technique that makes the product fail-proof. Both of these procedures work similar to some extent as they envisage and identify detects in a product.
What is the main objective of poka-yoke to achieve?
Poka-yoke aims to prevent defects by catching, correcting, and eliminating mistakes at the source.

Is Kanban a poka-yoke?
Kanban boards for project management also have the Poka-Yoke concept integrated. Once you have stipulated your Work In Progress limit for a particular work stage, the board will keep you in check, letting you know you've added too many items to be processed than was allowed.
