I keynoted at Agile Australia in June 2015 and InfoQ recorded it. If you know somebody who's doing "Agile in name only," they should watch this video. Here's the blurb:
For an approach that emphasizes simplicity, success with Agile is surprisingly difficult. Some teams see amazing results. They're able to respond to changing needs, deliver new releases every day, and do so with nearly zero defects. Other teams complain that Agile makes things worse, not better. They get less done and spend more time in pointless meetings.
What is about Agile that creates such different experiences? Let's take a step back and look at what makes Agile work. What's the point of these Sprints, stories, Scrums, and other practices? What leads to success and what leads to struggle? It's time for a frank discussion about what it takes to succeed with Agile.
