Since Detroit declared bankruptcy on July 18, the city's crippling problems with corruption, unfunded benefits and pension liabilities have gotten the bulk of airtime. But equally at fault for its fiscal demise are the city's management structure and union and civil-service rules that hamstring efforts to make municipal services more efficient. I would know: I had a front-row seat for this dysfunction.

Last year, I served as chief operating officer of the Detroit Department of Transportation. I was hired as a contractor for the position, and in my eight months on the job I got a vivid sense of the city's dysfunction. Almost every day, a problem would arise, a solution would be found—but implementing the fix would prove impossible.

We began staff meetings each morning by learning which vendors had cut us off for lack of payment, including suppliers of essential items like motor oil or brake pads. Bus engines that the transportation department had sent out to be overhauled were sidelined for months when vendors refused to ship them back because the city hadn't paid for the repair. There were days when 20% of our scheduled runs did not go out because of a lack of road-ready buses.

The obvious solution for a cash-tight operation is to triage vendor payments to ensure that absolutely essential items are always there. But in Detroit, no one inside the transportation department could direct payments to the most important vendors. A bureaucrat working miles away in City Hall, not responsible to the transportation department (and, frankly, not responsible to anyone we could identify), decided who got paid and who didn't. That meant vendors supplying noncritical items were often paid even as public buses were sidelined.

A major expense for Detroit is the cost of lawsuits filed against the city for various alleged injuries on municipal property. At the transportation department, there were hundreds of claims arising from bus accidents alone. How many of those claims were fraudulent? How many were settled (with the cost of settlement and legal fees posted against DDOT's budget) at unnecessarily high cost?
