It may seem like a simple question... "Do we have an agreement?"... yet it is powerful . It promotes clarity. It defines desire. When answered, it means we're on the same page.
The simple task of setting a meeting time is fertile ground for unclear agreements. Is "We will meet at 10am" a clear agreement? Well, maybe. But, maybe not.
What does "meet at 10am" mean? Does it mean that's what time I get up from my desk and move toward the meeting space? Does it mean that's what time I arrive to fill up my coffee cup and get something to eat? Or does it mean that I'm in my seat, ready to work? Yep. Could be all of those. Not very clear.
Or, how about... "Will you be at the meeting on Friday?" where the response is "I'll try." In my world, the definition of "try" is often looking to get credit for something you have no intention of actually doing. So, "try" doesn't create an agreement.
"Do we have an agreement?" is binary. Response choices are "yes" or "no". If there isn't a clear "yes", we have work to do. Bring it on.
