Organizations, in search of better operational performance and competitive advantage, have sought alternatives for identifying problems and opportunities for improvement in the context of supply chain management. In this context, Social Network Analysis, in conjunction with Graph Theory, emerges as one of the tools used for this purpose. Therefore, this article seeks to analyze the effects of relational and structural immersion in the logistics performance of an aluminum framing company from a case study. To obtain data and information, semi-structured interviews were conducted with the manager responsible for the purchasing sector. The results show that some suppliers have considerable influence on the supply chain, whether positive or negative. It can be positive, bringing the consolidation of partnerships between companies with a strong and reliable relationship and negative, for example, when the product suffers breakdowns or delays in the process. We also highlight the need for the company to establish logistics performance indicators in a better way to quantitatively assess the impacts of the chain on operational activities in order to assist in more assertive strategic decision-making.
