Explanation
According to the SAFe Implementation Roadmap, culture change is the last step in the transformation process. It states that "culture change comes last, not first. You can't change a culture until you have changed the underlying behavior and the results that the behavior produces" 1. Therefore, the best way to change the culture is to adopt new approaches that deliver better outcomes and then anchor them in the culture by reinforcing the benefits and values they bring. This is consistent with Kotter's model of leading change, which also suggests that anchoring new approaches in the culture is the final stage of a successful change effort 23.
