This research explores the integration of traditional Quality Management (QM) techniques such as TQM, Lean Manufacturing, Six Sigma, and ISO 9001 with Fourth Industrial Revolution technologies like IoT, AI, and Digital Twins. Focusing on Wärtsilä, a multinational company in marine and energy solutions, the study examines how it addresses sustainability, efficiency, and customer value challenges in advanced manufacturing. Through a descriptive case study, including participatory observation, interviews with quality control managers and engineers, and employee questionnaires, the research highlights the positive impact of combining traditional QM practices with Industry 4.0 technologies. Key benefits include improved product quality, operational efficiency, and environmental conservation, achieved through digital twins and predictive maintenance, allowing for real-time monitoring and reduction of defects and downtime. The study also discusses how Wärtsilä proactively manages training and infrastructure costs with strategic investments in human capital. It offers recommendations for industries aiming to adopt similar integrations to stay competitive in the global market.
