The growing importance of the role of purchasing and supply management in the support to organizations for achieving increased profitability and cost reduction has been highlighted in the academic and industrial communities. This scenario has motivated this research, whose scope includes analyzing the Supply area of a firm that belongs to a business segment of corporate services in a structured way and supported by the academic literature, towards identifying opportunities for improvement that would help in the evolution of this group of activities. Thus, the goals, processes, strategy and structure related to purchasing were studied in order to support the development of a case study. Ten dimensions of observation drawn from the academic literature guided the analysis of the Supply area considered for the case study, what resulted in the identification of opportunities and culminated in the establishment of a list of proposed improvements. Some of these proposals were implemented and their results are presented in the end of this study, including the creation, within the structure of the department, of a cell that seeks continuous improvement.
