For example when I start demonstrating Career OnDemand, I usually start by saying that the design principles that guided the team were 'people centricity', 'networking and collaboration at the core' and 'instant insight for all'.
When I am done demonstrating the Career OnDemand prototype, I always recap the demo by saying that we started with goals, talked about the activities that helped a person accomplish that goal, saw the feedback a person received in the context of a goal and then looked at how he relied on collective intelligence from his network of people to accomplish that goal.
I have said this more or less 170 times to customers, partners and colleagues over the past 18 months. With every iteration the product and the pitch gets better and better. I do goof up once in a while. Some times I get distracted by a customer question and fail to cover a concept. Sometimes, someone interrupts the sessions and I lose my focus. But I never fail to learn in these sessions. It is amazing.
