Investigating the Effort of Using Business Process Management Technology: Results from a Controlled Experiment

Business Process Management (BPM) technology has become an important instrument for supporting complex coordination scenarios and for improving business process performance. When considering its use, however, enterprises typically have to rely on vendor promises or qualitative reports. What is still missing and what is demanded by IT decision makers are quantitative evaluations based on empirical and experimental research. This paper picks up this demand and illustrates how experimental research can be applied to technologies enabling enterprises to coordinate their business processes and to associate them with related artifacts and resources. The conducted experiment compares the effort for implementing and maintaining a sample business process either based on standard workflow technology or on a case handling system. We motivate and describe the experimental design, discuss threats for the validity of our experimental results (as well as risk mitigations), and present the results of our experiment. In general, more experimental research is needed in order to obtain valid data on the various aspects and effects of BPM technology and BPM tools.
