We present Time-BPMN which is an extension to the current version of the Business Process Modeling Notation (BPMN). Time-BPMN captures the temporal perspective of business processes. This extension deals with the various temporal constraints and dependencies that may occur while characterizing real world business processes. Time-BPMN allows for the specification and depiction of temporal constraints and dependencies within a BPMN diagram. It not only extends, but also simplifies certain existing temporal BPMN constructs. With our extension, BPMN becomes expressive enough to account for a very large set of real world business processes that are time dependent.
