A framework for assessing poka-yoke devices
نویسندگان
چکیده
This study introduces a framework for assessing poka-yoke devices (PD), encompassing both those designed for quality control (referred to as quality PD) and those designed to control hazards to health and safety at work (referred to as safety PD). The framework assesses the processes of the design, operation and maintenance of PD, rather than the outcomes of these processes. The development of the framework involved three stages: (a) defining 15 attributes of PD, identifying those that provide fail-safe characteristics and those that inform best practices in design, implementation and maintenance; (b) defining what the set of evidence and what the sources of evidence should be for assessing the existence of each attribute; the sources include documents, interviews, observations and a meeting to discuss the results of the assessment with company representatives; and (c) defining a scoring system to express the results of the assessment. The application of the framework is illustrated by means of assessing four PD; two of them being concerned with quality and two with safety. © 2012 The Society of Manufacturing Engineers.

Using Poka-Yoke Techniques for Early Defect Detection
Poka-yoke is a quality assurance technique developed by Japanese manufacturing engineer Shigeo Shingo. The aim of poka-yoke is to eliminate defects in a product by preventing or correcting mistakes as early as possible. Poka-yoke has been used most frequently in manufacturing environments. Hewlett Packard currently develops its Common Desktop Environment software to run in twelve locales or lan...
متن کاملPoka Yoke system based on image analysis and object recognition
Poka Yoke is a method of quality management which is related to prevent faults from arising during production processes. It deals with “fail-safing” or “mistake-proofing”. The Poka-yoke concept was generated and developed by Shigeo Shingo for the Toyota Production System. Poka Yoke is used in many fields, especially in monitoring production processes. In many cases, identifying faults in a prod...
متن کاملSome Spreadsheet Poka-Yoke
Whilst not all spreadsheet defects are structural in nature, poor layout choices can compromise spreadsheet quality. These defects may be avoided at the development stage by some simple mistake prevention and detection devices. Poka-Yoke (Japanese for Mistake Proofing), which owes its genesis to the Toyota Production System (the standard for manufacturing excellence throughout the world) offers...
متن کاملPreventive Methods in Logistics Poka-yoke and Failure Mode and Effect Analysis (fmea)
Preventive methods are seldom used in logistics, although there is increasing awareness of their potential. This paper presents two examples of preventive methods currently in use, Poka-Yoke and FMEA (Failure Mode and Effect Analysis). The implementation of Poka-Yoke, the mistake proofing methodology, has been shown to drastically reduce the enormous warranty costs, including logistics costs, w...
