Extensão da notação e modelo de processo de negócio para inclusão de riscos

Abstract

Business Process Model and Notation (BPMN) is currently a process modeling language with the best didactics for use, with a structure that is easy to understand and use. However, the notation does not address any element or functionality to present risks. Risks are future situations that cause some type of impact, most of which are negative. Presenting these risks in process models would allow those involved to perform their activities with more caution, in order to avoid them. Event-driven Process Chain (EPC) has become an option because it allows controlling different risk situations that a process may be involved in. In order to improve BPMN in this direction, it is essential to approach risk management in their processes, without losing the present didactics. This work aims to develop an extension to BPMN 2.0 allowing to include risks to the processes. The extension includes two features: presentation and risk mitigation, which were identified through exploratory research with experts that works with process modeling, risk management and internal controls, and through studying of the literature. These features seek to be intuitive, facilitating the construction of more comprehensive models. In order to test this extension, an experiment was carried out with students from public and private institutions and people working in the process modeling area. The experiment compared two models, one described with the BPMN notation with the extension and the other using the method of Cockburn's written use case notation. The results of the experiment suggest that the added elements in BPMN do not decrease the correctness of the responses in relation to the process models, but decrease the mental effort and rework in their reading when compared to processes described through a textual representation containing risk information.
