One of the more powerful behind-the-scenes players in Minneapolis City Hall, City Coordinator Steven Bosacker, announced Thursday that he is stepping down after six years to travel the world.

Once Gov. Jesse Ventura's chief of staff, Bosacker made his mark on City Hall by implementing a results-based management system that helped city officials and the public track progress across all departments. His post is significant at City Hall, overseeing the heads of finance, regulatory services, communications and other departments.

Bosacker, 51, is the latest in a number of high-ranking city officials to depart in the past year, joining the city's fire, regulatory and development chiefs.

He said he loves his job "as much as I've ever loved it" and no events at City Hall precipitated his exit. His last day will be in March.

"We're just sad, because he's wonderful, just a brilliant guy," said City Council President Barb Johnson. "I'll tell you, I've always worried about him because sometimes I call him on a Sunday, and he's at work. He just is a workhorse."

In a statement, Mayor R.T. Rybak praised Bosacker's work in implementing results-based performance management, hundreds of management performance reviews and the 311 call center.

"Steven Bosacker is one of the most gifted public administrators in the history of Minnesota and his work for Minneapolis had been nothing short of transformative," Rybak said.

Bosacker's management system is on display every Tuesday morning at City Hall, when departments present the public with their progress in meeting various targets.

"It's great for people like us because we can go and sit in and hear what that department has to say, what they've accomplished, what they're working on, where they're having difficulties," said Council Member Meg Tuthill. She added: "I think it's fabulous."

Bosacker said he sold his condominium in January and will also sell possessions. He plans a yearlong journey with stops in Peru, Brazil, Portugal, Morocco, Lebanon, Egypt, Vietnam, Cambodia and India.

It's not his first extended trip abroad. After leaving the Ventura administration, Bosacker lived for nearly two years in Germany, where he did consulting.

"There's a bit of a world history with me that I can't quite shake," Bosacker said. "I'm not quite done with the rest of the world."
