In this study we analyze the difference in perception regarding the BPM initiative between management and employees of an operational department of the Peruvian Air Force and compared the BPM Maturity with benchmark studies. The research question is: Does differences in perception of BPM Maturity between managers and employees lead to differences in the evaluation of process performance? The underlying BPM maturity model consists of 7 dimensions: Process Awareness, Process Description, Process Measurement, Process Control, Process Improvement, Process Resources and Knowledge, and Process IT Tools. The total dataset consists of 241 respondents and validated scales were used to measure BPM Maturity and Process Performance. The results show that there are no significant differences between managers and employees. Regression analysis shows that Process Measurement, Process Control and Process Resources are the key determents for Process Performance. The results offer opportunities to launch new BPM initiatives within the case study organization.
