AB  - There have been several assessment tools developed to evaluate the adoption of lean in construction industry organizations, but there is no generally accepted approach to consistently measure the adoption. Further, the existing models lack structure and use limited reference to the existing models outside of the construction domain. Some models have also excluded the involvement of industry experts in the development and evaluation process. Capability maturity models have been found to be a valuable approach for self-assessment, continuous improvement, and benchmarking. This study aims to formally identify categories for lean organization adoption as a foundational step to create a maturity model to evaluate the lean maturity of an organization. The authors found a total of 214 different categories in the literature and subsequently grouped, removed, and refined them with assistance from lean experts.  This analysis yielded a total of 33 potential categories. These categories were then rated by industry experts to determine their inclusion in the maturity model. Future work will include developing a model, validating it, and disseminating the maturity model to the community.
