The document summarizes Intel's implementation of the Scaled Agile Framework (SAFe) at its MDO organization. It describes how Intel transitioned from a vertical to horizontal structure with 177 scrum teams organized into 12 Agile Release Trains. While the intent was to follow SAFe principles and standard rules across the organization, variations in agile maturity and other challenges emerged. Key lessons included that SAFe is a set of guidelines rather than a prescriptive template, and successfully implementing even simple rules at scale is difficult due to factors like team sizing, co-location constraints, and pacing teams across geographies.
