Title: An analytical approach to data quality in business processes
Process-aware information systems enact business processes using data of various sources. A basic assumption underlying business process management, is that the information system truly reflects the current state at any moment. Based on this assumption, humans do not need to physically sense the current state for deciding what activity to perform and how to perform it. However, in reality data stored and used in information systems is not always completely reliable. The talk will describe a research project where possible runtime errors in process data are considered at process design time, with the aim of increasing the robustness of the process with respect to such errors. First, a formal theoretical model of how data errors are manifested in business processes will be presented. A usability study of this model will be described. Based on this model, a property of Data Inaccuracy Awareness (DIA) will be defined, and an algorithm for identifying non-DIA states in a process model will be presented. We expect the DIA analysis to support prediction of data errors in processes. Next, an approach for analyzing the impact of data items in a business process will be presented. The approach defines a set of primitives for relationships among process elements. It transforms a business process model into a relational database representation of these primitives, employing algorithms for assessing the overall impacts of each data item in the process. Impact analysis should support the identification of critical data items, whose inaccurate values might highly impact the process and its outcome.
