The Supply Chain Management (SCM) is a new concept of enterprise business processes management that surpasses the limits of the companies to also include its main clients and suppliers. With this concept the integration and information exchange among companies has become more and more important for these companies performance and their supply chains systems. The SCM consolidation in different industries has been developed with the Information Systems (IS) assistance. In this context, the current dissertation aims to map and analyse the main businesses processes of Castrol do Brasil Ltda (which is a British multinational subsidiary of Petroleum segment - BP) under the perspective of its Information Systems (IS). The dissertation will consider either those systems limited to this company boundaries, as well as the systems responsible for this company`s interface with some of its most important supply chain members, focusing, however, on productive part and logistic operations (outbound). From this study, a critic can be elaborated to Castrol do Brasil Ltda SCM, under IS perspective.
