proceso. En este artículo quisiera que detalláramos su historia, concepto, beneficios y metodología para implementarla. Historia Poka-Yoke es un sistema creado por Shigeo- Shingo en los anos 60s. El principal objetivo era mistake proofing definition eliminar la posibilidad de realizar un error en el proceso de manufactura. Este concepto se ha logrado transmitir en el mundo entero gracias a sus beneficios e impactos económicos en las plantas de manufactura ya que la calidad y el costo de reproceso fueron los indicadores que logran cambios significativos. Un dato curioso es que en sus inicio se llamo baka-yoke pero como este nombre mistake proofing six sigma significa a prueba de tontos se corrigió a poka-yoke con el tiempo. Definición Una técnica en manufactura para evitar errores. Esta herramienta proporciona conceptos claros para minimizar defectos en los procesos relacionados al personal o máquina. Tipos de errores que Pokayoke nos puede ayudar a eliminar: Errores en manufactura Errores de proceso No realización de un paso del proceso Falta de partes o piezas Falta de información Partes o piezas erróneas o dañadas Niveles de Poka-Yoke. Nivel alto: Detectar errores en la fuente antes de ser realizados Nivel medio: Detectar errores en el momento de su realización, en este caso la corrección se puede realizar y su impacto no es alto. Nivel bajo: Detectar el error después de su realización, en este caso se puede corregir antes de ser un problema con riesgo alto. Beneficios de Poka-Yoke Prevenir errores y pérdidas en el proceso realizadas por el personal. Mejorar el proceso para lograr realizarlo bien desde la primera vez Reducir la variación en procesos de producción Metodología para realizar un pokayoke: Esta metodología la se puede realizar cuidando tengamos un problema pero siempre sugiero hacerla en modo preventivo, esto quiere decir buscar problemas en

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.

Poka-yoke (ポカヨケ?) [poka yoke] is a Japanese term that means "mistake-proofing" or “inadvertent https://en.wikipedia.org/wiki/Poka-yoke error prevention”. The key word in the second translation, often 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 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 mistake proofing 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, but as this means "fool-proofing" (or "idiot-proofing") the name was changed to the milder poka-yoke.

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)" or "foot depressing the clutch/brake pedal" must be performed before the car is allowed to start. The requirement of a depressed brake pedal to shift most of the cars with an automatic transmission from "Park" to any other gear is yet another example of a poka-yoke application. Over time, the driver's behavior is conformed with the requirements by repetition and habit. History[edit] The term poka-yoke was applied by Shigeo Shingo in the 1960s to industrial processes designed to prevent human errors.[5] Shingo redesigned a process in which factory workers, while assembling a small switch, would often forget to insert the required spring under one of
