Given the importance of structuring organizations in supply chains as a mechanism for competitiveness, as well as process management for the good operational performance of these chains, this article aims to map and analyze the business processes of a supply chain of the ceramic sector located in northeastern Brazil. To achieve the proposed objective, Lambert, Cooper, and Pagh’s (LCP) model of supply chain management is adopted, which comprises, within its analysis dimensions, the mapping of the dimensional structure of the chain, its processes, and management components. As a result, it was possible to characterize the configuration of the chain under analysis, highlighting the company's proximity focused on the upstream direction of the chain and, consequently, the complexity of the supply operations. Furthermore, based on the problems and inefficiencies identified during the mapping of the supply processes, this study proposes suggestions for changes and improvements to the ceramic sector's supply chain analyzed. By providing a detailed analysis of the dimensional structure of the chain, its processes, and managerial components, this article contributes to the continuous improvement of organizations by providing a practical discussion on the structuring of supply processes and emphasizing the importance of overcoming the identified inefficiencies.
