  4. Business Process ManagementAnd some of its Research Challenges • Business processes can be very large and complex • Thousands of concurrently executed process instances • High need for flexibility and adaptability • Feedback and learning from real process executions • PAIS correctness and PAIS robustness are fundamental Example of an Automotive Engineering Process Healthcare Process
