This is an interesting article, framed around the discussion of agile versus waterfall. However, it also touches on many other topics, like why the Agile Manifesto was needed, includes a great classification framework for Product vs Project Management, and discusses the role of a project manager in an agile organization. The article is long, but thought provoking. Enjoy!
