Robert Rider, chairman of the Postal Service Board of Governors, announced the plan at a meeting of the board today.
While Congress has considered various legislative steps to restructure the Postal Service, little action has been taken by its members.
Mr. Rider didn't disclose specifics, but a Postal Service spokesman said the plan would likely look at what kind of steps can be taken under existing law.
The plan "will provide the framework for how the Postal Service of the future will be reformed and revitalized to meet the changing needs of our customers, the American people, over the next 10 to 20 years," Mr. Rider said. "It is clear to all of us that the time for debating the need for reform is past."
Separately Mr. Rider today announced the Postal Service is getting out of the business of providing a secure e-mail system, called PosteCS.
