The document discusses how Scrum is a framework to help teams be agile, but it does not guarantee agility on its own. While Scrum can work without an agile culture, it does not work as well. Having an truly agile team allows for great work to be done and Scrum to be used effectively, but meetings and overhead from Scrum processes can increase costs without an agile mindset. The document cautions that implementing engineering practices early in sprints is important. Overall, Scrum provides a framework but an agile culture and mindset are needed to fully realize the benefits of agility.
