Seeking Resource Planning solutions

Hey there - I'm looking forward to posting the results of my current research project - resource planning software and solutions. We've grown tremendously at CivicActions over the last year or so, and despite a threatening economy, we expect to continue growing. This means managing dozens of project contributors across dozens of projects with shifting deadlines, scope, etc.. Complicating this is the fact that lots of project contributors wear or can wear multiple "hats" - a themer might also do configuration, eg. Or a PM who can do visual design. One of the biggest stumbling blocks in my research so far is that most project management software considers project contributors to be one-dimensional, so their availability shows up under one category or another, which doesn't give an accurate picture to how many PM or Design hours are actually available, when all the hours for a hyphenate are in one category. I want to be able to track resource availability and be able to answer questions like "Which PM's are available to start a project in three weeks?" and "When should we launch this project, which is heavy in theming in week 6?" etc..

I've seen a lot of "workforce management" solutions and "project management" solutions.

Any thoughts or recommendations would be appreciated, and I"ll post the results of my research here sometime in the hopefully near future.

Rock on PMs!
