Este trabalho apresenta uma proposta de método para a melhoria de fluxos de informação em ambientes administrativos usando princípios da mentalidade enxuta e da reengenharia de processos. O método foi criado através de características encontradas em duas metodologias existentes da mentalidade enxuta e de soluções desenhadas pela reengenharia de processos com este propósito. Estas características foram identificadas, selecionadas e adaptadas para uso no método seguindo um modelo de gestão de mudança. Em seguida, o método foi aplicado em um fluxo de informação em uma empresa do interior de São Paulo, seus resultados foram medidos apresentando boas melhorias em relação à maior velocidade de processamento de informações, redução da quantidade de pessoas necessárias e maior porcentagem de tempo de agregação de valor. Por último, foram apresentadas observações sobre as limitações do método e da generalização dos resultados da aplicação apresentada. / This work presents a proposal of method for the improvement of information flows using the principles of lean thinking and solutions from business process reengineering (BPR). The method was created using characteristics encountered on two existing lean office methodologies, and with the solutions presented by business reengineering. Those characteristics were identified, sorted and adapted to be used in the method based on a change management model. The proposed method was implemented in an information flow of a company in the brazilian state of São Paulo, and its results were measured, presenting significant reduction of the information flow lead time, reduction of people needed to process the information and a larger percentage of added-value time. Finally, limitations of the method and the application results were presented.

In the competitive environment that companies not only target on the improvement the efficiency in their delivery system but also redefine how supply chain should function in order to operate more effective from original supply to final consumption. A lot of firms have now cooperated together in the supply chain instead of fighting alone to deal with the competition in this global environment market place. Therefore, in the supply chain management, information sharing is important to effective coordination between partners. This research aims to develop an Architecture-Oriented model for the Supply Chain Information Sharing management. In this model, the interaction between organizations, structure elements, systems, and information sharing for the Supply chain management are well defined. Adopting this model, management can understand and control the entire supply chain more easily. Also, this model can help management make the better decision so management can more effective to collect the important information of organizational structures and behaviors for what are needed. Architecture-Oriented Supply Chain Information Sharing Management Model (AOSCISMM) is based on the enterprise architecture theory and method. Using the structure-behavior coalescence (SBC) approach to simulate the Supply Chain Information Sharing Management Model, we are able to fully express the situation of organizational structure, business processes, and information systems clearly to reduce business reengineering risks. The major achievement of this research is to advise a new model for better supply chain information sharing management and also bring the new vision for the supply chain management of information sharing.

Domestic marketing is in vigorous development these years. On the one hand is to be in accordance with the fast changing of the market due to the goods flow concerns the survival development very much; on the other hand, because of the impact of joining the WTO and the challenge of globalization, enterprises are in the tight corner that even they don¡¦t go out, there are rivals attack actively. The empires feel the pressure, and of course, so do those small and medium-sized enterprises. Under this kind of circumstance, most of the enterprises develop the logistics and the information flow as the main consideration, but as the finance flow, is only for accounting. Though the academic world has re- searches on marketing, most of them are about the logistics and the infor- mation flow. As the part of combining the reformation of finance flow, per- haps one certain company gets some advantages from it, but to the industry or enterprise connecting with supply chain as the main body, there is no complete integrated discussion about upstream and downriver and let alone the research regarding the integrated profit. This research takes the leading domestic food industry, Uni-President, as the object. The whole supply chain takes the Uni-President as the core and extends to the upstream supplying system, downriver retailing system and the end of logistics to discuss the alternation of finance flow¡¦s procedures and the benefits from the application. Through the case description and analysis, the customers (the sales companies and distributors), the collaborative banks, all Uni-President¡¦s manufactories and the suppliers (manufactures) start out for the potential need to the finance flow. It reveals the fact that how the group coordinates, discovers and plans to find out the essential reformation and core value to the finance flow step by step and by way of continuous communi- cation and persuasion to push the reformation which joins the banking group, suppliers and customers to the finance flow. To this entire supply chain, it encourages the fund¡¦s turnover, upgrades the business credit, widens the financial accommodation, reduces the risks of operation, and accelerates the operation profits in the chain. Those mentioned above provide an invisible and powerful competitive advantage and a closer strategic cooperative value between upstream and downriver for all the strategic partners in this supply chain to create a marvelous and a win-win situation. Hoping this research could help the industries/private enterprises who are willing to be devoted on this and be as an important reference while they plan the reformation of the finance flow to the supply chain.
