U.S. government agencies have been directed to share with each other software code that has been developed on a customized basis. Much of the code involves commercial vendor offerings. In addition to interagency sharing, government units are required to share portions of their customized code with the general public, a move characterized as promoting an open source approach. The OMB, along with federal CIO Tony Scott and CAO Anne Rung, earlier this month issued a final federal policy incorporating the sharing initiative.
