  In the era of Agile methodologies, organizations are exploring strategies to
scale development across teams. Various scaling strategies have emerged, from
"SAFe" to "LeSS", with some organizations creating their own methods. Despite
numerous studies on organizational challenges with these approaches, none have
empirically compared their impact on Agile team effectiveness. This study aims
to evaluate the effectiveness of Agile teams using different scaling methods,
focusing on factors like responsiveness, stakeholder satisfaction, and
management approach. We surveyed 15,078 Agile team members and 1,841
stakeholders, followed by statistical analyses. The results showed minor
differences in effectiveness across scaling strategies. In essence, the choice
of scaling strategy does not significantly impact team effectiveness, and
organizations should select based on their culture and management style.
