Visualizations and collaboration are great, but the team needs to understand what they are building, why they are building it, and the steps they take to build it.  What are we doing and when? Who is responsible for what decisions? What do handoffs look like? When do we talk to the customer? When do we talk to each other?

At Trimble, through value stream mapping, Lean Coffees, and other exercises, we worked with a team of 18 years to come to an agreement of how they worked every day (and it wasn't always easy).  We helped them replace assumptions with understanding, so they could focus, finish, and fine-tune without a lot of unnecessary conversation.
