Abstract

This article presents the development of a model to integrate lean thinking principles into the organizational culture of organizations, which makes employees/teams act naturally and efficiently. This model is called “Integration of Lean Thinking in the Organizational Culture” (ILTOC) and results from the integration of three approaches: (1) levels of organizational culture from Edgar Schein, (2) lean thinking principles, and (3) the 4P model. The developed model includes a five-step framework to drive users in its implementation and was applied in a case study carried out in an administrative department (Budgeting) of a Portuguese organization from the renewable energies area. The application of the model resulted in a more efficient and productive team. By combining the three aforementioned approaches, the model allowed continuous improvement to emerge as a natural way of working for the stakeholders of this organization. As a result, there was an improvement in key performance indicators (KPI) such as cost, delivery, quality, safety, and morale.
