This study aims to assess the maturity of product quality management within Industry 4.0. The study employs a case study approach, applying a maturity assessment tool to two manufacturing units of an automotive components enterprise, which serves as a supplier to prominent trucks and buses manufacturers. The assessment instrument comprises a questionnaire encompassing six dimensions such as customer service, product development, process control management, system integration and management, leadership and culture. Managers with high-ranking leadership positions from various functions, evaluate the significance criteria and the degree of application or progression of these practices within the organization. Radar charts were employed to visually present the acquired results, thereby highlighting gaps that emerge between the level of importance attributed to these practices and their implementation within the organization. The research underscores that certain dimensions are still in incipient stages, warranting prioritized attention, particularly in the event of a Quality 4.0 development agenda. The assessed maturity levels unveil ongoing initiatives, with some dimensions nearing consolidation; however, opportunities for advancement in embedding quality within Industry 4.0 persist across the dimensions. This study underscores the multidimensional nature of the proposed assessment tool, positing it as a valuable instrument for navigating the evolution of organizational processes over time, specifically in the context of integrating quality within Industry 4.0 implementation journeys.
