Classification graph of Poka-Yoke techniques for industrial applications: Assembly process case studies effectiveness evaluation

It is widely acknowledged that the expenses associated with substandard quality constitute a significant portion of a company's overall costs. Consequently, organizations adopt quality management systems and implement corrective and preventive measures to reduce these expenses. Within these implementations, Poka-Yoke techniques are notably prominent. Theoretically, these techniques are designed to prevent mistakes that lead to costs, especially quality-related costs associated with nonconforming products. This study proposes a classification of Poka-Yoke techniques and a methodology for evaluating the effectiveness of these techniques. The methodology was applied in the evaluation of selected techniques implemented in various assembly tasks. This assessment relies on objective characteristics of the techniques. The value of this method lies in its ability to easily evaluate techniques to implement in areas where interventions are needed to increase the reliability of the production system. Thus, it serves as a simple tool to help design new and improve existing workplace organizations.
