Not a direct answer to your request, but you may also be interested in this book called “Dreaming in Code” [1] which documents the reasons and the whys of why the Chandler project failed, a book written by some of the people directly involved (if I remember right) and a book that I’ve also heard that is quite excellent (I’ve personally didn’t read it yet even though it has been on my to-read list for quite some tome, I did read though in real time the blog posts of some of the developers working on the project).
