occur or makes the error immediately obvious once it has occurred. When to Use Mistake Proofing When a process step has been identified where human error can cause mistakes or defects to occur, hard mistake proofing especially in processes that rely on the worker’s attention, skill or experience. In how to error proof a process a service process, where the customer can make an error which affects the output. At a hand-off step in a error proofing vs mistake proofing process, when output or (for service processes) the customer is transferred to another worker. When a minor error early in the process causes major problems later in the process. When the consequences of

an error are expensive or dangerous. 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. Consider: Elimination—eliminating the step that causes the mistake proofing six sigma error. Replacement—replacing the step with an error-proof one. Facilitation—making the correct action far easier than the error. If you cannot make it impossible for the error to occur, think of ways to detect the error and minimize its effects. Consider inspection method, setting function and regulatory function. Choose the best mistake-proofing method or device for each error. Test it, then implement it. Three kinds of inspection methods provide rapid feedback: Successive inspection is done at the next step of the process by the next worker. Self-inspection means workers check their own work immediately after doing it. Source inspection checks, before the process step takes place, that conditions are correct. Often it’s automatic and keeps the process from proceeding until conditions are right. Setting functions are the methods by which a process parameter or product attribute is inspected for errors: The contact or physical method checks a physical characteristic such as diameter or temperature, often using a sensor. The motion-step or sequencing method checks the process sequence to make sure steps are done in order. The fixed-value or grouping and counting method counts repetitions or parts or weighs an item to ensure completeness. A fourth setting function

This activity is also know by the Japanese term poka-yoke, from poka (inadvertent errors) and yokeru (to avoid) - pronounced POH-kuh YOH-kay. Although this common-sense concept has been around for a long time, it was more fully developed and popularized by Shigeo Shingo in Japan. The philosophy behind error proofing is that it is not acceptable to make even a very small number of defects, and the only way to achieve this goal is to prevent them from happening in the first place. In essence, error-proofing becomes a method 100% inspection at the source rather than down the line, after additional value has been added (wasted). Achieving extremely high levels of process capability requires this type of focus on prevention rather than detection. You may not realize it, but you probably encounter many examples of error-proofing in your every-day life, as outlined below: Examples From Every-Day: The brake-shift interlock device on your automatic transmission vehicle prevents you from starting the engine unless the brake is depressed and the shift selector is in park or neutral. A tennis ball hung from a screen in your garage can make parking easier, and avoid cr

(April 2014) (Learn how and when to remove this template message) Poka-yoke example: Ethernet cable plug is designed to be https://en.wikipedia.org/wiki/Poka-yoke plugged in only one orientation. Poka-yoke (ポカヨケ?) [poka yoke] is a Japanese term that means "mistake-proofing" or “inadvertent error prevention”. The key word in the second translation, often http://elsmar.com/Forums/showthread.php?t=19269 omitted, is "inadvertent". There is no Poka Yoke solution that protects against an operator’s sabotage, but sabotage is a rare behavior among people.[1] A poka-yoke is any mechanism mistake proofing in a lean manufacturing process that helps an equipment operator avoid (yokeru) mistakes (poka). Its purpose is to eliminate product defects by preventing, correcting, or drawing attention to human errors as they occur.[2] The concept was formalised, and the term adopted, by Shigeo Shingo as part of the Toyota Production System.[3][4] It was originally described as baka-yoke, error mistake proofing but as this means "fool-proofing" (or "idiot-proofing") the name was changed to the milder poka-yoke. Contents 1 Usage 2 History 3 Implementation in manufacturing 4 Benefits of Poka Yoke implementation 5 See also 6 References 7 Further reading 8 External links Usage[edit] More broadly, the term can refer to any behavior-shaping constraint designed into a process to prevent incorrect operation by the user. A simple poka-yoke example is demonstrated when a driver of the car equipped with a manual gearbox must press on the clutch pedal (a process step, therefore a poka-yoke) prior to starting an automobile. The interlock serves to prevent unintended movement of the car. Another example of poka-yoke would be the car equipped with an automatic transmission, which has a switch that requires the car to be in "Park" or "Neutral" before the car can be started (some automatic transmissions require the brake pedal to be depressed as well). These serve as behavior-shaping constraints as the action of "car in Park (or Neutral)"
