Some people consider Agile to be THE silver bullet

In my experience the people who consider Agile a 'silver bullet' are usually high-level managers who have heard about Agile but don't understand what's required to make it successful. They hope Agile will miraculously fix their organization's problems without them having to do anything. When Agile inevitably fails to fix everything, usually due to the aforementioned organizational problems, the managers claim Agile is a sham. Of course, adopting Agile even though it will won't succeed in their environment gives these managers a few months of breathing space, and when Agile fails they can blame all their problems on it.
