Metrics that are easy to read and simplify complex formulas are awesome.  Charts that show improvement rock.  Real-time telemetry amazes.  However, if we stare at the dashboard too long it is easy to replace numbers for people.  We let systems and schedules run the people instead of vice-versa.  How do you make sure the people are always the first point of focus? 

Great leaders would never sacrifice the people to save the numbers; they would sooner sacrifice the numbers to save the people. – Simon Sinek
