What is it about?
This study introduces a Lean Six Sigma 4.0 (LSS 4.0) framework, built on the DMAIC (Define, Measure, Analyze, Improve, Control) methodology, to optimize how companies manage occupational exams for employees. Focusing on a real-world case from a Brazilian organization, the research tackles the sudden surge in medical exams triggered by a change in health service providers. By applying LSS 4.0 principles, the research team identified key process inefficiencies and implemented a series of improvements to streamline exam management and reduce unnecessary costs.

Why is it important?
Occupational exams are essential for employee safety and regulatory compliance, but managing them can become costly and chaotic, especially in large organizations or during supplier transitions. This research offers a practical, step-by-step approach for organizations to regain control, cut waste, and improve accuracy in their health monitoring processes. It not only bridges a gap in academic literature but also provides companies with a replicable model to improve efficiency and make smarter decisions in the era of Industry 4.0.
Perspectives
This project began as a response to a very practical and urgent challenge: how can organizations cope with a sudden rise in occupational health checks without compromising efficiency or compliance? What we found is that by blending Lean Six Sigma tools with the interoperability and automation capabilities of Industry 4.0, it’s possible to redesign these processes from the ground up.
