Chicago is required to have a chief administrative officer; it hasn’t for decades – Chicago Sun-Times

Inspector General Deborah Witzburg cited the botched Hilco smokestack demolition in Pilsen as just one of 11 “missed opportunities to promote efficiency and economy through interdepartmental coordination” that might have been different, if only the chief administrative officer’s job had been filled. "And that’s handicapping the city’s ability to deliver effective and efficient city services. The municipal code speaks specifically to the need for coordination among city departments and requires the mayor to appoint an administrative officer, among whose duties is ensuring coordination among city departments."
