Many leaders are enticed to engage in an agile methodology, such as Scrum, XP, FDD, TDD, DSDM, and lean, because there seems to be an implicit promise of faster, better, and cheaper results. The gathering together of teams of technical- and business-minded people to do something better than they ever have before is not only a promise, but an expectation of the Agile Manifesto. However, what may not be so clear is that leaders can't just plug in the new methodology and expect the firm to perform miracles on its own.
