We all know what Product Portfolio Management (PPM) is. Right? Is the system that let's us assess product ideas, compare them and ultimate fund a few for development. But it also let's continually assess the health of funded projects to kill those that aren't as successful as we'd like. Well, a few weeks back, I met with the folks at Planview (company website) to get some insight into their products. And I think there's a little more to their software than first meets the eye.
