There're a couple of spots I want to point that we liked that I pointed out.
In the waterfall area, I still find that customers want a Ferrari but have the budget of a bicycle.
With the agile mindset, check out how the customer now has a baby strapped to him and want's a car that has more room now.
The scrummaster jumping from his tower to impale the product owner bringing over some "actually, could we...." protecting the team.
The M.V.P. in the Lean section. When we build products for clients we try and keep them close the M.V.P. as possible. It's a challenge at first as they want everything possible. However, once they see us deliver the product every two weeks they have that "a-ha" moment and realize they don't need it all right now. Build the m.v.p., use it, build some more.
