The objective of this project is to develop a methodology to evaluate the performance of a production system through the use of performance indicators regarding lean production in relation to the objectives of quality, manufacturing and productivity and its variables, quality, time, and cost. The expected objective is that this methodology will help the company to measure performance in a lean production environment. A presentation of the evolution of the lean concept will be performed, its principles and techniques, and the presentation of the three views of the lean thought. Within this context, a new view will be presented which seeks a formal integration between the production control and quality control at the shop floor level. The most used performance indicators will be described. They are used to measure the performance of a lean system and levels of employment for each indicator will be defined at the levels of the shop floor, company and supply chain. This project proposes a methodology that allows measurement of a company s performance that quantifies benefits that can be expected in the implementation of lean techniques. Finally, it will be shown through the application of the proposed methodology in the case study that the introduction of the concepts discussed in the fourth approach of lean production, which deals with the change of material and information flow from the production systems, helps the company to be more competitive. This concept translates into layout changes in the manufacturing process and in the production control systems.
