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.
The term "idiot-proof" became popular in the 1970s. [2] It may have been invented as a stronger-sounding version of foolproof, as the force of foolproof had declined due to frequent usage. Perhaps for the same reason, "foolproof" is now a formal term, whereas "idiot-proof" remains informal.
It is similar to a proof by example in mathematics. [1] It is an example of jumping to conclusions. [2] For example, one may generalize about all people or all members of a group from what one knows about just one or a few people: If one meets a rude person from a given country X, one may suspect that most people in country X are rude.
In mathematics, certain kinds of mistaken proof are often exhibited, and sometimes collected, as illustrations of a concept called mathematical fallacy.There is a distinction between a simple mistake and a mathematical fallacy in a proof, in that a mistake in a proof leads to an invalid proof while in the best-known examples of mathematical fallacies there is some element of concealment or ...
Definitional retreat – changing the meaning of a word when an objection is raised. [23] Often paired with moving the goalposts (see below), as when an argument is challenged using a common definition of a term in the argument, and the arguer presents a different definition of the term and thereby demands different evidence to debunk the argument.
When you file your dispute, you may need to provide proof that a mistake was made. Acceptable proof could include copies of billing statements, letters from creditors, or a police report if the ...
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.
The above argument works because the exact same reasoning could be applied if the alternative assumption, namely, that the first object is blue, were made, or, similarly, that the words 'red' and 'blue' can be freely exchanged in the wording of the proof. As a result, the use of "without loss of generality" is valid in this case.
