Kent Beck boots points in favor of real schedule estimates, communication improves
http://codebetter.com/blogs/darrell.norton/archive/2005/02/25/56032.aspx
“The first edition of Extreme Programming Explained had a more abstract estimation model, in which stories cost one, two, or three "points". Larger stories had to be broken down before they could be planned. Once you started implementing stories, you quickly discovered how many points you typically accomplished in a week. I prefer to work with real time estimates now, making all communication as clear, direct, and transparent as possible.”

21 Rules of Thumb for Shipping Great Software on Time
Shipping great software on time is a difficult but not impossible task. Elements you think would count the most count for very little. Development methodology, process, technical prowess, excellence of tools and depth of project management skills all influence the outcome of a software development project; but nothing indicates success as much as the manager’s ability to focus on a few critical and conceptually simple things.
