Virtual reality (VR) has proven to be a versatile technology with applications extending beyond entertainment, playing a significant role in training and cognitive development. Executive functions (EF) are essential cognitive processes that regulate behavior, decision-making, and adaptation to dynamic workplace contexts. Despite their importance, effective strategies to train these functions in industrial workers remain underexplored. This study presents the development and validation of a VR-based training system designed to strengthen five key executive functions through three video games: cognitive flexibility, inhibitory control, working memory, planning, and logical reasoning. A development methodology inspired by the Game Development Software Engineering (GDSE) cycle was adapted to meet cognitive training requirements. Three VR video games were designed, each targeting specific executive functions. The first game trains cognitive flexibility through dynamic rule-switching tasks; the second integrates inhibitory control and working memory by requiring users to classify and discard objects under changing conditions; the third promotes planning and logical reasoning by challenging users to optimize spatial arrangements within a limited time. Validation was conducted exclusively through usability and user experience (UX) testing with experts in psychology, engineering, and human resources to assess the system’s potential effectiveness in EF improvement. Usability testing results indicate high acceptance in terms of immersion, interaction, and understanding of game mechanics. Functional evaluations suggest that the system effectively promotes EF training, with specific recommendations for optimizing interface design and realtime feedback mechanisms. Preliminary evidence supports the feasibility of VR video games as an effective strategy for EF development in workplace settings. Future research will focus on implementation in industrial environments and longitudinal assessment of its impact on cognitive performance.
