The Impact of the Poka-Yoke Method on Error Rate during Transitions to System 2 Activities

With the increasing demands for efficiency and process optimization across industries, growing attention is being paid to the role of the human factor within these systems. Nevertheless, some methods, such as poka-yoke, have so far been little explored from the perspective of cognitive ergonomics. The aim of this thesis is to contribute to addressing these shortcomings by examining the impact of the poka-yoke method on the error rate when switching to more cognitively demanding tasks. For this purpose, an experiment involving 42 university students was designed and conducted. Statistical analysis of the results confirmed a reduction in both error rate and performance variability in the task with poka-yoke implemented as a direct result of the method’s application. However, based on the collected empirical data, no significant effect on error rate was demonstrated in the subsequent task. By identifying future directions for research, the thesis provides a foundation for future exploration of this topic.
