28th International Congress on project Management "Project Management in the Digital Decade"

The construction industry continues to face persistent challenges such as delays, cost overruns, and strained stakeholder relationships, prompting a shift towards more collaborative, value-driven, and sustainable delivery methods. This paper introduces the IPD Cookbook, a practical tool from a Swiss IPD research project designed to support the adoption of Integrated Project Delivery (IPD) in Switzerland. The Cookbook serves as a quick reference guide, offer-ing a structured overview of key IPD values, principles, and instruments that foster collabora-tive, efficient, and value-driven project delivery. It links six foundational values to 13 operation-al principles and 36 practical instruments. The Cookbook also addresses critical soft factors such as trust, communication, and team culture. The development process follows a consensus-based Ontology Engineering Approach that supports a team to reach consensus through iterative evaluations and improvements. A multi-method process—combining literature reviews, expert workshops, surveys, and case study insights —ensured that the Cookbook offers practitioners a solid foundation for adopting IPD in Switzerland and beyond.
