Interaccion de la aplicacion de la filosofia Lean y la felicidad en el trabajo

Abstract

We analyze, through this doctoral thesis, how different workers of different backgrounds, culture, training and language perceive the progressive implementation of the Lean philosophy at all levels, in a workshop of rubber parts manufactured by injection, dedicated to the automotive industry, in their daily happiness perceived in the environment of the job they occupy. For this, a qualitative methodology is presented, through the development of the "case of success" of the manufacturing workshops in Cáceres - Tangier, exposing the history of everything applied from the beginning of the investigation, to the current situation. This methodology can be applied to any type of industry, and it is possible to analyze how the application of the Lean philosophy in this particular industry would affect the happiness of its workers. The quantitative basis used as working method will be the joint execution of 3 surveys, in the workshops of Spain and Morocco, to each of the operators that have a seniority superior to the start of the study (April 2014), which allows, therefore, to be able to compare and evaluate on the part of the subject, the situation before and after the implementation of the Lean philosophy within the company. For the analysis, measurement and interpretation of the surveys, the Rasch model is used.
