Hi emgub,
I agree that prospective employers aren't going to read the whole resume the first time through. Most don't do so until you're there for the interview. However, aside from HR folks, IT decision makers do read some material from each resume to decide which candidates they have an interest in. The whole point is to steer the reader to the information you want them to know most about you. For an IT project manager, that should be some of the key projects you worked on and the value you brought to the organization. If the resume is structured properly and written well, you can achieve this within the 30-second review time that's typical for hiring managers.
