It's no secret that the U.S. Postal Service has struggled for years against such headwinds as private-sector competition, digitization and unfunded government mandates including six-day-a-week delivery service. But under CFO Joe Corbett, the $67 billion government-owned, commercially operated organization, which won a Gold Alexander Hamilton Award for Cash Management in 2009, continues to find new opportunities among the many challenges.

T&R: Despite all the financial changes the USPS is going through, you managed to create best-in-class innovations with your AHA award for cash management. Are there more innovations to come?

Corbett: Absolutely. We were the first government entity to implement Sarbanes-Oxley. We completed the implementation in our fiscal year ending September 2010, and we got a clean opinion from our audit firm, Ernst & Young, in November of last year. It was an enormous task when you think about it. Everyone bet we weren't going to be able to do it. It's nice to be able to overcome that, because the odds are against an organization that is decentralized, with 36,000 locations, the largest retail network in the county and a long, long legacy, so you have systems built on top of systems.
