I signed up for the trial, went through the walk-thru and played with the system myself. It seems clear that:
(a) it would be very easy to load this tool up with a portfolio of projects with their labor demands (I fixate on the labor part, but I suppose the point is more generally about resources) and then I could use it to explain what we are planning to use all of our people on (and why we are going to have to make some tough decisions about what we take on when). I would just start with roles (not named individual contributors). This would be a simple way to get a lot of value within hours.
(b) this is a cool system that is nipping at the heels of full-on PPM systems. Check out the financials stuff and the goal-based portfolios.
There was nothing I disliked. I'm sure they could do more to help me use this across the whole management team, but I haven't looked that closely at what they already have there.
I only looked at the trial, so no value has been realized!
