Are we producing new insights, ideas, or approaches, and feeding them back into the system?
Are we learning, or just repeating?
Are we making each other better as a result of our collaboration?
Are our ideas relating to and building on each other's, and serving as springboards to the next idea?
Does everyone on the team feel like they can express new ideas or ways of working?
Could we REALLY re-invent the wheel?
How can we tell a "good" collaboration experience from a "bad" one? (successful vs. unsuccessful, efficient vs. ineffecient, etc.)
How do we know if we're getting better at collaborating?
Does this process / platform / team make sense for what we need to do?
