From the title, it would sound like this post would represent a complete counterpoint to the basis of this blog. But I assure you, this is not the case.
Instead, I want to point your attention to an article from Siddharta Govindaraj.

Agile and Iterative Development, by Craig Larman, is a book I recommend to managers, project leaders, and software developers who want to know more about agile. The book is clear and concise in its descriptions and provides many useful tips along the way to understanding agile.
