Poka Yoke = ‘’mistake proofing’’ or ‘’fool proofing’’
Poka Yoke can be explained using a simple example: while installing software the system illustrates the terms & agreements for the software. Unless the user press the ‘I agree’’ check box he won't be allowed to proceed further with the installation activities. Thus the software vendor ensures that only those users who have agreed to the terms & conditions use the product.
To some extent, mistake proofing can be eliminated by automating intelligently.
