The NTIA infrastructure report referenced in note 4 comments on the lower rate of ISDN implementation in the United States as compared to several other countries (pp. 183–187), and it also references efforts to deploy fiber to the home and fiber to the curb (pp. 100–109) as part of the improvements to transmission systems under way.

9. Although the SSA implemented a comprehensive systems modernization plan during the 1980s that brought its information systems back from the brink of failure, a recent assessment concluded that the "SSA can do a great deal more to exploit the benefits of on-line automation" (National Research Council, 1991, Elements of Systems Modernization for the Social Security System, and 1990, Systems Modernization and the Strategic Plans of the Social Security Administration, National Academy Press, Washington, D.C.).

The IRS is itself on the threshold of a major Tax Systems Modernization program that will significantly enhance its ability to exploit the benefits of dealing with information in electronic, as opposed to paper, form. That program is under evaluation by the Computer Science and Telecommunications Board.

A discussion of these issues in the context of software engineering can be found in the following report: Computer Science and Technology Board, National Research Council. 1989.
