Brett Schuchert of ObjectMentor extends the concept of TDD to driving positive meeting outcomes. It's a great idea, and this is the first place I've seen it. Meetings have the same problem of scope creep and deadline overrun that projects do.
The debate after the post led to other methods or frustrations about meetings. I strongly believe that "...there are no open laptops or phones in my meetings! I say, stay engaged or stay out. (unless it’s a CxO of course)"
