This article developed an optimization proposal for the manufacturing process of integral eight-meter linear kitchens in the CASA MADEIRA company, using the DMAIC method (Define, measure, analyze, implement and control). The work was carried out in order to solve the delay in the manufacturing process of integral kitchens of eight linear meters, since its operation was not adequate and presented deficiencies in its production stages.

During the diagnosis of the situation, it was possible to determine that the whole kitchen manufacturing process had an efficiency of 58% with respect to the installed capacity, given errors in the planning and programming of tasks.

As alternative solutions, the following was carried out instructions and standardization documents of the process, as well as training of personnel. Of this way it was possible to achieve 91% in the efficiency of the production process, offering a comprehensive solution to the problem presented, thus maximizing the effective production times and covering the demand for integral cooking, allowing maximum optimization of the process performance and generating greater Annual income for the company.
