Business processes have to adopt the changes driven by the market to remain competitive. This requires improvement of business processes, which can be carried out by understanding the existing business processes. For this AS-IS business process models are built that represent the actual situation of the enterprise. In this paper, we propose an approach to build an AS-IS process model from employee's descriptions instead of instance executions in information systems. We also present an algorithm that builds an AS-IS model from control flow perspective and we further elaborate it with the help of a case study.
