BPMN Modeling Mistakes – Why Correct-Looking Diagrams Break Process Logic

This video examines a set of BPMN modeling pitfalls that appear syntactically correct but subtly violate execution semantics, leading to broken or unintended process behavior. Focusing in particular on boundary events, the tutorial demonstrates how apparently valid diagrams can produce unexpected token flows and logical inconsistencies. Through several interactive examples, viewers are invited to identify modeling errors before each case is explained in detail. The analysis highlights typical problems related to boundary event placement, control-flow construction, and implicit assumptions about token propagation. The session emphasizes the importance of understanding BPMN execution semantics—not just notation—when designing robust process models. By exposing these hidden failure modes, the video helps practitioners recognize and avoid common modeling traps that can compromise correctness in real-world workflows. This is Video #65 of the BPMN Series.
