Business Process Modeling and Measuring Waiting Times in a German ED: An Approach for Identifying Improvements

Abstract

This case study is about the modeling of the business processes in the interdisciplinary ED of the Robert-Bosch-Hospital in Stuttgart, Germany. An EPC process model for the complete stay of a patient was created. Time intervals for different subprocesses were measured to support the model and to identify waiting times. The case study works out that the modeling of current business processes is a good basis for finding improvements.

Waiting times and weaknesses were identified in the improvable implementation of the MTS, the bed management, and the insufficient integration of the IT systems.

The material in this case study was prepared originally for Project Seminar SS 2012 at the University of Hohenhiem, Germany under the supervision of Profs Kirn and Wickramasinghe.
