Proposal: Lean Model for Continuous Improvement as a Cost Reduction Strategy, ¨SME: SL Service Automotive Mechanical Engineering¨

The current economic situation in Mexico requires companies to adopt the strategies that allow them to acquire competitive capacity, reduce their costs and increase their productivity by managing agile and slender processes all to stay in the market and provide their products and services. To this end, large companies began to adopt manufacturing methods developed in Japan that help competes in the international market, national or local, known as Lean Manufacturing. Everything starts by drawing a diagram of the value chain of the process showing all the activities carried out to obtain the product or service, costs but not value delaying the completion of the same and for that reason should be eliminated. Lean defines these activities as waste, which is presented in the production and service processes, but through the use and application of the Lean tools will allow us to eliminate them. This article proposes an improvement model based on lean manufacturing for the service process of the SME, also taking into account the literature reviewed in the state of the art, which will allow us to reduce its total time of process and as a consequence is the decrease in costs, increase in productivity, increase in profits, all this in order to place it in a competitive state, thus ensuring its permanence in the business. In the beginning, the waste identified in the process is presented to later determine the appropriate Lean tools for its elimination and finally the present VSM (current) and a future (desired) VSM of the process are traced together with a cost-benefit analysis for the implementation of the proposed tools.
