The goal of mistake-proofing or poka yoke is to eliminate mistakes. In order to eliminate mistakes, we need to modify processes so that it is impossible to make them in the first place. With mistake-proofing solutions, many repetitive tasks that depend upon the memory of the worker are built into the process itself. Mistake-proofing frees the time and minds of the workforce to pursue more creative and value-adding activities.  Mistake-proofing also involves a change in the mindset of the organization. Organizations must establish a mistake-proofing mindset that promotes the belief that it is unacceptable to allow for even a small number of product or service defects.
