I think I figured out why so many companies jumped on board the Agile approach. Companies heard Productivity Bonus and Put Stuff into a List Of Things to Do, and left out all the rest of their responsibilities. One of my past companies was like "We're going to take an Agile approach to everything! Except, we're not going to shield developers from everyone who has stuff in the backlog, and we're going to have other meetings during the day on top of the scrum meetings to check on your progress, and we're going to measure points in time instead of complexity".

I feel like the creators of the Agile Manifesto would be really upset at all of the poorly implemented processes. Because all of us developers are pretty upset.
