Ever wonder why factories, warehouses, grocery stores, and other similar businesses usually have a sign that says something like, "Accident-Free for 82 Days." It's because the simple act of measuring and reporting that number makes it evident across all levels of the organization that this metric is important. We measure what matters. No one wants to be the guy who sets the sign back to zero.
Measuring and reporting continuous improvement metrics sends a clear signal to the organization that this is important. When people know that you're tracking data around their improvement work, there's an increased sense of accountability that drives engagement and activity.
