Rooney awards these prized coins that commemorate ESC as the birthplace of "Command and Control" in honor of outstanding performance and excellence. At the awards ceremony, Rooney stated:

   The superb contribution Aon Management Consulting/Rath&Strong has been
   making to training our airman, officers and civilian personnel is
   critical to our mission.  The results of these Lean efforts are already
   helping the Electronic Systems Center to significantly reduce our costs
   and to improve our performance.  Thank you for a job very well done.

The Air Force, as part of its Smart Operations for the 21st Century, is working with Aon/Rath & Strong and its Lean system to strip out waste from critical processes, allowing for significant time and cost savings. As part of this effort, Aon/Rath & Strong, in partnership with the University of Massachusetts Donahue Institute, led a series of Lean Rapid Improvement Events at Hanscom Air Force Base, which resulted in greater cost savings. Additional projects currently underway are designed to reduce process time in staffing and should result in an immediate savings for the Air Force of millions of dollars.

"We are certainly proud of the work Aon Management Consulting/Rath & Strong does on behalf of the Air Force," said Dan Quinn, chief executive officer and president of Aon Management Consulting/Rath & Strong. "The bottom line is that we achieve results with our clients, not just for today, but so that they can independently carry forward the benefits of their work with us. That's the true measure of success. Aon/Rath & Strong is delighted to receive this recognition from the U.S. Air Force."
