The Supply Chain Management (SCM) is creating many opportunities and challenges for world business competition. In spite of this, there are still just a few models that offer an effective SCM analysis. Within this context, this dissertation attempts to propose a model for a supply chain analysis based on key dimensions that are necessary for a successful SCM. The key dimensions considered in this dissertation are: business processes integration, key supply chain members identification, information sharing, and appropriate supply chain performance measures. In order to validate the model and to evaluate its application, a case study was conducted in different supply chains of a big national manufacturer of CNG (Compressed Natural Gas) cylinders for vehicles. Towards the SCM analysis, this manufacturer is considered in this application as the supply chain`s focal company. With the model`s application in these different supply chains, it was possible to figure out a more intense information share and use of performance measures in the SRM (Supplier Relationship Management) business process than in the CRM (Customer Relationship Management) business process. In CRM, it was also found that the supply chains are more integrated with the focal company when the cylinder is the chain`s main product and less integrated when the chain`s main product is another, for instance, a brand new car.
