Decision-making is one of the most important and underestimated activities of every organization. Decisions define the commitment of our most limited resources and are the determining factor between success and failure. How individual decisions are taken directly impacts the decision outcome. Therefore, the method used to decide is of utmost importance. Choosing by Advantages (CBA) is a decision-making method that has been growing in application and acceptance in the last few years within the International Group for Lean Construction (IGLC) community. Existing publications regarding CBA mainly discuss the benefits of the method in theory and in practice, but none of them explain how the method was applied nor if it was also broadly implemented across organizations to the different project levels. This paper closes the gap by giving guidance and insights on the development and rollout of CBA trainings for the construction industry based on the case study of Daimler AG. The authors conclude that the implementation of CBA requires a thoughtful plan that leaves room for adjustments in accordance to the project team's needs.
