Service-oriented architecture (SOA) is developed to address new business challenges; they have become more competitive and integrated information systems. In addition, technologies such as business process management (BPM), Business activity monitoring (BAM) and web services are an essential complement to SOA. In this paper we integrate several of these technologies in a single application that allows, in a phase of a business process, to perform the analysis of input suppliers to the company, through the generation of a decision tree, using embedded code of free tool Weka data mining to feedback the business process to improve it. The result was a prototype able to select suppliers through a decision tree.
