Hal Macomber is The Project Reformer, and he's got a new site, Let's Play Catch, which deals with helping people learn how to successfully deliver large projects. At the core of his approach is the art and science of making reliable promises.
As someone who used to manage software development, I am keenly interested in how you deliver projects on time. Hal is a good read - I've been following his stuff for over a year. Another good project management blog belongs to Johanna Rothman, Managing Product Development.
