The proposed approach has been customized and apply in the case of a lean production system in order to demonstrate its efficiency and effectiveness. The research approach and its associated methodology consists of three stages: (1) a qualitative research using the Grounded Theory, which provide a theoretical model on the the employees behavior within the analyzed lean production system; (2) a quantitative research, survey based on a designed questionnaire, for the investigation of the motivation – satisfaction relation; (3) a quantitative research for the ergonomic risk assessment associated with repetitive upper limb movements (that are dominant in the case of the assembly line that has been studied) using the OCRA method for the improvement of the workers stress. The research results contribute to the knowledge development and to the the diminishing of the occupational hazards and generating workplace wellbeing.
