Draft paper: BPMN-based specification of task descriptions

Business processes modelling helps to specify requirements to build an information system (IS), this is the requirements engineering (RE) process. The Business Process Modelling Notation (BPMN) is a business process modelling technique, this technique results in Business Process Diagrams (BPDs). However, business processes can not directly be translated to functional requirements of an IS (Vara & Sánchez, 2009). This gap was researched, a method for bridging the gap was developed, and the method was tested in practice. This gap is between the business and the system domain, to which their paper was applied. Vara and Sánchez (2009, p. 124) define the goal of this method as ”to present an approach that provides methodological guidance to properly specify functional requirements from business processes”. This introduction will shortly explain the proposed approach. After the introduction, an example is used to elaborate on the method and related literature on the subject is discussed. The author of the method, Jose Luis de la Vara Gonzalez, is a PhD from the Technical University of Valencia. His field of interests lies within software methods, which lead him to work for the Research Centre on Software Production Methods. Ranging from 2007 to 2011, he has published fifteen papers. A global overview of the method is provided by Vara and Sánchez (2009), which can be seen in Figure 1. The method, or new approach as the paper defines, is clearly divided in two stages. These stages (and the preliminary stage) are shortly introduced, before using the method in the example. Before the first stage, business processes are modelled in collaboration with the stakeholders. Together with written business rules, and a table
