Proposta de melhoria de um processo utilizando mapeamento de fluxo de valor e conceitos do lean office

Abstract

With the increase in global competitiveness and the country's current economic crisis, companies must seek alternatives to remain in the market. One of the ways a company to survive in this scenario is by using the concepts of Lean Manufacturing, a philosophy developed in Japan at the Toyota Motor Company by Taiichi Ohno and widespread across the world as an example of success in reducing costs and production time, by the elimination of waste. One of the tools used to implement Lean Manufacturing is Value Stream Mapping. This tool assists in identification of the hidden wastes of a production line. Lean Manufacturing has been adapted for non-manufacturing processes, the so-called Lean Office. In Lean Office, the raw material of the process is information, and its purpose is to reduce or eliminate the waste associated with the flow of information. The following work aims to propose improvements in a process based on the Lean Office philosophy, using as main tool the Value Stream Mapping. The mapped process was the flagging process, for gas station, of a large fuel distributor in Brazil. The high lead time of the process hinders the company's business negotiations. The steps followed in this work were: the mapping of the current state, the identification of the hidden waste of the process, the mapping of the future state, which counts on the improvements contained in the implementation plan. The results generated a processing time of 48.5% lower, and increased it by 48% in the time of value adding, significant improvements to the process.
