Analysis of Solutions Dedicated to Non-Conformity Prevention

Purpose: The purpose of the work is to analyze the use of solutions aimed at preventing incompatibilities and assess the effectiveness of these solutions to minimize the risk associated with the quality of manufactured products. The analysis presented in the work is based on the Poka-Yoke error prevention concept used in the selected enterprise. The paper presents the state of the company before and after the introduction of Poka-Yoke method. Approach/Methodology/Design: The research methods used in the paper were the analysis of company data, analysis of literature states, as well as methods using the Poka-Yoke concept. The company was surveyed in 2017/2018 during the system implementation. Findings: The results on the control card for nonconforming units of type "p" were also presented, where the analysis showed that the introduction of the Poka-Yoke system to the company reduced the number of nonconformities by 6.69%. Practical Implications: Implementation of the Poka-Yoke system will allow enterprises to create conditions in which an error cannot happen, or will be immediately visible. The result of such an action may be distracting operators from repetitive operations, reducing the number of deficiencies and induce immediate action when a problem occurs. Originality/Value: Showing how the use of the Poka-Yoke system affects the prevention of inadvertent error in enterprises, by determining the differences between the state of the enterprise before and after the introduction of the Poka-Yoke system, there is an opportunity to improve the economy and contribute to the social and economic sphere.
