This book constitutes the proceedings of the BPM Forum held at the 23rd International Conference on Business Process Management, BPM 2025, which took place in Seville, Spain, during September 2025. The BPM Forum hosts innovative research which has a high potential of stimulating discussions. The papers cover a diverse and timely set of topics, reflecting the evolving socio-technical and AI-enhanced landscape of BPM. They explore themes such as the use of large language models in process monitoring and predictive analytics, RPA-induced technostress, blockchain-based compliance and documentation systems, process similarity and fairness in decision making, as well as new methods for model orchestration and simulation. The 23 papers included in this book were carefully reviewed and selected from a total of 132 submissions to the conference. They were organized in research tracks on foundations, engineering, and management.
