Abstract: A system and method are provided to map and transform any Gantt Project Plan tasks workflow with tasks, subtasks, milestones, temporal constraints, task relationships, task duration types, and resources into equivalent Business Process Modeling Notation (BPMN) XML model ready for deployment and execution by any BPMN-compliant engine. The method provides input Gantt models, necessary for an automation or manual tool, to implement explicit Gantt Project Plan conversion into executable BPMN process model with corresponding XML specification. A system and method are also provided for Gantt BPMN execution automation to track and monitor task, subtask and milestone completion using Gantt Project Management. The system and method can play an important role in adopting BPM for Gantt Project Management automation to eliminate human discretion, reduce project and task manual coordination to increase efficiency, productivity, human collaboration with Gantt BPM automation technology.
