Purpose ‐ Financial institutions have been engaged in numerous business process reengineering (BPR) projects to make their organizations more efficient. However, the success of BPR projects in banks varies significantly and it remains a challenge to systematically
discover weaknesses in business process landscapes. Based on the flow chart notation language this paper seeks to argue for the definition of weakness patterns in order to automatically identify potential process weaknesses. Design/methodology/approach ‐ The authors
developed weakness patterns in the flow chart notation language based on design science principles. To systematically derive process weaknesses that can be formalized, they analyzed each element of the flow chart notation as it was used in a real-life case. They furthermore tested the identified
patterns in reality in order to evaluate their validity. Findings ‐ The authors identified various potential weakness patterns that helped in automatically identifying weaknesses in process models. To some extent these findings are generalizable and transferable to
other process modeling languages. Research limitations/implications ‐ The pattern-based approach depends upon how well structural weakness patterns are defined and formalized. Identified problems remain "potential" weaknesses until a manual analysis reveals that the
identified potential weaknesses are actually real weaknesses or not, e.g. due to law regulations. Practical implications ‐ Using weakness patterns allows for automatically identifying potential process weaknesses in existing flow chart models. This way, this research
helps in improving the so far manual analysis of process model landscapes. Originality/value ‐ The approach is a new way of looking for process weaknesses through process weakness patterns.
