Activities an organization performs can be viewed as a sequence of events and responses to them. Event-driven solutions have emerged for event management to help capture events and respond by triggering other events. Nevertheless, designing solutions which conforms with a problem domain is not trivial task. Therefore, holistic understanding of the problem domain is essential. To understand the problem domain, we use formalism of Topological Functioning Model which analyses an organization as a system from computation independent viewpoint and helps to represent holistically both structural and functional aspects of an organization. By applying case study analysis research method, the article discusses how the use of Topological Functioning Model can help to derive an event-driven solution which conforms with the problem domain of an organization.
