“A lot of people think Scrum is all there is in Agile, that following Scrum, the daily stand-up, etc. will get you the benefits of being agile. The 20-Day Challenge allows participants to explore what Agile really is, a set of values and principles. By taking each in turn and asking the reader to really think about it, each will discover the depth of what was written back in 2001. This is a great resource for anyone wanting to explore the real meaning of Agile.”
