ResearchPod Summary
Conversational AI systems, such as chatbots and virtual assistants, are increasingly integrated into business processes to handle customer service, scheduling, and information retrieval. While these systems offer high flexibility and adaptability, they present a significant challenge for traditional Business Process Model and Notation (BPMN). BPMN is primarily designed for deterministic, rule-based processes, making it difficult to represent the non-deterministic, context-sensitive, and dialogue-oriented nature of modern AI agents.
To bridge this gap, the authors developed BPMN4CAI, an extension that adheres to the BPMN 2.0 standard. Using a Design Science Research (DSR) methodology, the researchers identified key functional requirements for Conversational AI—such as natural language interaction, context preservation, and dynamic decision-making—and mapped them to specific modeling elements. The extension utilizes the standard's native <extensionElements> mechanism, ensuring that the new components remain compatible with existing BPMN-compliant modeling tools.
The BPMN4CAI framework introduces several specialized elements to enhance process modeling:
The authors demonstrated the utility of these elements through an insurance consultation case study, showing that the extension improves both the transparency of AI-driven processes and the technical bridge between process models and their implementation.
As organizations increasingly rely on hybrid actors—where AI and humans collaborate—the ability to formally model these interactions is critical for governance, compliance, and operational efficiency. BPMN4CAI provides a theoretically grounded and practically implementable way to integrate AI into existing process landscapes without abandoning established industry standards.
