The search for excellence and operational benefits forces organizations to adopt new types of techniques and approaches for the systematic creation of innovative solutions. In view of this context, this paper describes the implementation of the Lean-TRIZ approach in a production line in a Portuguese food organization. In a first step, a continuous improvement model was designed for a technical/organizational system, by combining the TRIZ methodology with Lean techniques and with the Kano Model. The initial analysis was carried out through techniques of direct observation, brainstorming and questionnaires to employees. This analysis allowed identifying the problems by identifying the root causes. Then, analytical instruments of the TRIZ methodology were applied. Finally, the level of employee satisfaction with the improvements introduced in the production line was verified through the Kano Model, which showed us positive results both from the point of view of the employee and the company. The main contribution of this paper is to determine, through a real case study, the potential of the Lean-TRIZ approach in helping organizations to implement a continuous improvement process.
