Doing Agile and Being Agile are different. Here is a popular infographic that explains what Agile really is and illustrates common misunderstandings about it:
Doing Agile is about the practices: standups, user stories, iterations, etc.
There are significant benefits from using Agile practices. I see it as “common sense” of getting work done. Adopting these practices will lead to benefits; perhaps 20% or more from what I have seen. This is widely reported by industry research such as Version One’s Annual report.
Being Agile is about our Consciousness or way of being. We may also refer to this as Mindset or Organizational Culture. It’s about how we see ourselves. How we relate to each other. How we behave. What we value. A recent post explains more about this: Agile Culture –> Self-managing People.
I put the ROI on this at 3x to illustrate how much impact this has on team and organizational effectiveness. It could be much more. We are talking about reinvention here – not applying a process change.
Bob Hartman noticed and coined the concept that Doing Agile is not Being Agile. See his slides.
