It's pretty similar to skill challenges done in literally the most boring way possible. In fact I'm not sure that it's possible to be that boring within the rules of 4e.
A skill challenge is trying to deal with a complex task, and part of the point is that everyone brings their own thing and they work out how to work together. And that the experts take on the hardest parts, with there being an intentional range of DCs being used. The final version of the skill challenge rules IIRC means that there had to be a range of difficulties.
