In the 21st century, leadership requires data. It is therefore of enormous importance that the Mayor's Office of CitiStat re-emerge as a powerful force for efficacy in Baltimore. On its website, CitiStat is described as a "small performance-based management group responsible for continually improving the quality of services provided to the citizens of Baltimore City." Perhaps it shouldn't be so small. It is often said that what gets measured gets done. So let's continuously measure how many dilapidated houses are torn down, how many gang members convicted, how much trash is collected, how many potholes are repaired, how free-flowing is I-83, and how much public art is displayed.
