The Unified Model Language (UML) has nine diagrams. One of them is the activity diagram. This allows the modeling of business processes. A business process is a set of logically related tasks executed to achieve a business result. Workflow systems are those systems based on software that allow automating total or partially a business process. Workflow is defined as a set of methods and technologies that offer facilities for the modeling and administration of diverse processes that happen inside a company. The Workflow Management Coalition (WfMC) has established a standard that allows the interoperability among applications workflow. The proposed standard includes a model of the workflow processes, Workflow Metamodel, and a language of specification of processes in XML (XPDL). ArgoUML is a CASE tool for the analysis and design of objects oriented software systems. ArgoUML uses NSUML metamodel implementing the UML metamodel defined by the Objet Management Group (OMG). The ArgoUML tool is open source and it allows building all the types of defined diagrams in UML. In this work, we propose an extension of the NSUML, the core of ArgoUML metamodel. In this way, the ArgoUML incorporates the possibility to model and to simulate workflow processes.
