Poka-yoke was originally baka-yoke, but as this means "fool-proofing" (or "idiot-proofing") the name was changed to the milder poka-yoke. [4] Poka-yoke is derived from poka o yokeru (ポカを避ける), a term in shogi that means avoiding an unthinkably bad move.
To complete Jidoka, not only is the defect corrected in the product where discovered, but the process is evaluated and changed to remove the possibility of making the same mistake again. One solution to the problems can be to insert a "mistake-proofing" device somewhere in the production line. Such a device is known as poka-yoke.
Some of Grout's most notable research focuses on the Japanese term poka-yoke, or "mistake-proofing". In May 2004, Grout received the Shingo Prize for Manufacturing Excellence in Research in connection with research in this field. Grout and his wife, Susan, have four children. [2]
An example is the interlock or lockout of reverse in the transmission of a moving car. This prevents errors, and prevention of errors is the most effective technique in error-tolerant design. The practice is known as poka-yoke in Japan where it was introduced by Shigeo Shingo as part of the Toyota Production System.
The theorist of important innovations related to Industrial engineering, such as Poka-yoke and the Zero Quality Control, Shingō could influence fields other than manufacturing. For example, his concepts of SMED, mistake-proofing, and "zero quality control" (eliminating the need for inspection of results) have all been applied in the sales ...
While virtually all major improvement paradigms in use in the West incorporate some element of visuality, the entire codified set of visual principles and practices, from the foundation of 5S through to visual guarantees (poka-yoke), rests on this definition: "The visual workplace is a self-ordering, self-explaining, self-regulating, and self ...
Perhaps for the same reason, "foolproof" is now a formal term, whereas "idiot-proof" remains informal. Several Murphy's law adages claim that idiot-proof systems cannot be made, for example "Nothing is foolproof to a sufficiently talented fool" and "If you make something idiot-proof, someone will just make a better idiot."
Poka-yoke, a Japanese term, was coined by Shigeo Shingo, a quality expert. [ 11 ] [ 12 ] "Safe to fail" refers to civil engineering designs such as the Room for the River project in Netherlands and the Thames Estuary 2100 Plan [ 13 ] [ 14 ] which incorporate flexible adaptation strategies or climate change adaptation which provide for, and ...
