Personally, I think the most valuable part of this presentation deals with how to not waste time when doing code reviews. Code reviews can be super costly if you aren't careful and Jason outlines some great ways to avoid being wasteful with the time and effort of your team.
Jason provides practical insight that can be applied to your software group no matter what the state of your code review process is. Think you don't have the time, budget, or backing to perform awesome code reviews? Think again.
