A Capability Maturity Model for Integrated Project Delivery

As the adoption of integrated project delivery (IPD) progresses, increasing evidence has highlighted its potential to improve project outcomes. However, as an emerging practice, there remains a lack of structured mechanisms to evaluate the maturity of its implementation, which can limit opportunities for learning and improvement. Therefore, this study introduces an IPD Capability Maturity Model (IPDCMM) to evaluate the maturity of IPD implementation at the project level. This model enables organizations to benchmark their IPD capabilities against established best practices, facilitating structured development and continuous improvement. This model is designed as a post-project assessment tool that evaluates the maturity of IPD practice upon project completion, providing critical insights for learning and future project enhancements. The methodology, underpinned by a pragmatic philosophy and guided by the principles of design science research (DSR), prioritizes achieving practical outcomes (artifact). It combines insights from IPD frameworks, maturity models from other fields, and three case studies. The IPDCMM was developed alongside the IPD Maturity Assessment Tool (IPD-MAT), an artifact validated via evaluation sessions and feedback interviews with key stakeholders of IPD case studies. This model provides a structured framework for assessing IPD implementation maturity and facilitates a pathway for enhancing IPD practices and achieving efficiency in project delivery.
