The public faces a high risk that critical services provided by the government and the private sector could be severely disrupted by the Year 2000 computing crisis. Financial transactions could be delayed, flights grounded, power lost, and national defense affected. Moreover, America’s infrastructures are a complex array of public and private enterprises with many interdependencies at all levels. These many interdependencies among governments and within key economic sectors could cause a single failure to have adverse repercussions. Key economic sectors that could be seriously affected if their systems are not Year 2000 compliant include information and telecommunications; banking and finance; health, safety, and emergency services; transportation; power and water; and manufacturing and small business. The information and telecommunications sector is especially important. In testimony in June, we reported that the Year 2000 readiness of the telecommunications sector is one of the most crucial concerns to our nation because telecommunications are critical to the operations of nearly every public-sector and private-sector organization. For example, the information and telecommunications sector (1) enables the electronic transfer of funds, the distribution of electrical power, and the control of gas and oil pipeline systems, (2) is essential to the service economy, manufacturing, and efficient delivery of raw materials and finished goods, and (3) is basic to responsive emergency services. Reliable telecommunications services are made possible by a complex web of highly interconnected networks supported by national and local carriers and service providers, equipment manufacturers and suppliers, and customers. In addition to the risks associated with the nation’s key economic sectors, one of the largest, and largely unknown, risks relates to the global nature of the problem. With the advent of electronic communication and international commerce, the United States and the rest of the world have become critically dependent on computers. However, there are indications of Year 2000 readiness problems in the international arena. For example, a June 1998 informal World Bank survey of foreign readiness found that only 18 of 127 countries (14 percent) had a national Year 2000 program, 28 countries (22 percent) reported working on the problem, and 16 countries (13 percent) reported only awareness of the problem. No conclusive data were received from the remaining 65 countries surveyed (51 percent). In addition, a survey of 15,000 companies in 87 countries by the Gartner Group found that the United States, Canada, the Netherlands, Belgium, Australia, and Sweden were the Year 2000 leaders, while nations including Germany, India, Japan, and Russia were 12 months or more behind the United States. The Gartner Group’s survey also found that 23 percent of all companies (80 percent of which were small companies) had not started a Year 2000 effort. Moreover, according to the Gartner Group, the “insurance, investment services and banking are industries furthest ahead. Healthcare, education, semiconductor, chemical processing, agriculture, food processing, medical and law practices, construction and government agencies are furthest behind. Telecom, power, gas and water, software, shipbuilding and transportation are laggards barely ahead of furthest-behind efforts.” The following are examples of some of the major disruptions the public and private sectors could experience if the Year 2000 problem is not corrected. Unless the Federal Aviation Administration (FAA) takes much more decisive action, there could be grounded or delayed flights, degraded safety, customer inconvenience, and increased airline costs. Aircraft and other military equipment could be grounded because the computer systems used to schedule maintenance and track supplies may not work. Further, the Department of Defense (DOD) could incur shortages of vital items needed to sustain military operations and readiness. Medical devices and scientific laboratory equipment may experience problems beginning January 1, 2000, if the computer systems, software applications, or embedded chips used in these devices contain two-digit fields for year representation. According to the Basle Committee on Banking Supervision—an international committee of banking supervisory authorities—failure to address the Year 2000 issue would cause banking institutions to experience operational problems or even bankruptcy. Recognizing the seriousness of the Year 2000 problem, on February 4, 1998, the President signed an executive order that established the President’s Council on Year 2000 Conversion led by an Assistant to the President and composed of one representative from each of the executive departments and from other federal agencies as may be determined by the Chair. The Chair of the Council was tasked with the following Year 2000 roles: (1) overseeing the activities of agencies, (2) acting as chief spokesperson in national and international forums, (3) providing policy coordination of executive branch activities with state, local, and tribal governments, and (4) promoting appropriate federal roles with respect to private-sector activities. Addressing the Year 2000 problem in time will be a tremendous challenge for the federal government. Many of the federal government’s computer systems were originally designed and developed 20 to 25 years ago, are poorly documented, and use a wide variety of computer languages, many of which are obsolete. Some applications include thousands, tens of thousands, or even millions of lines of code, each of which must be examined for date-format problems. The federal government also depends on the telecommunications infrastructure to deliver a wide range of services. For example, the route of an electronic Medicare payment may traverse several networks—those operated by the Department of Health and Human Services, the Department of the Treasury’s computer systems and networks, and the Federal Reserve’s Fedwire electronic funds transfer system. In addition, the year 2000 could cause problems for the many facilities used by the federal government that were built or renovated within the last 20 years and contain embedded computer systems to control, monitor, or assist in operations. For example, building security systems, elevators, and air conditioning and heating equipment could malfunction or cease to operate. Agencies cannot afford to neglect any of these issues. If they do, the impact of Year 2000 failures could be widespread, costly, and potentially disruptive to vital government operations worldwide. Nevertheless, overall, the government’s 24 major departments and agencies are making slow progress in fixing their systems. In May 1997, the Office of Management and Budget (OMB) reported that about 21 percent of the mission-critical systems (1,598 of 7,649) for these departments and agencies were Year 2000 compliant. A year later, in May 1998, these departments and agencies reported that 2,914 of the 7,336 mission-critical systems in their current inventories, or about 40 percent, were compliant. However, unless agency progress improves dramatically, a substantial number of mission-critical systems will not be compliant in time. In addition to slow governmentwide progress in fixing systems, our reviews of federal agency Year 2000 programs have found uneven progress. Some agencies are significantly behind schedule and are at high risk that they will not fix their systems in time. Other agencies have made progress, although risks continue and a great deal of work remains. The following are examples of the results of some of our recent reviews. Last month, we testified about FAA’s progress in implementing a series of recommendations we had made earlier this year to assist FAA in completing overdue awareness and assessment activities. These recommendations included assessing how the major FAA components and the aviation industry would be affected if Year 2000 problems were not corrected in time and completing inventories of all information systems, including data interfaces. Officials at both FAA and the Department of Transportation agreed with these recommendations, and the agency has made progress in implementing them. In our August testimony, we reported that FAA had made progress in managing its Year 2000 problem and had completed critical steps in defining which systems needed to be corrected and how to accomplish this. However, with less than 17 months to go, FAA must still correct, test, and implement many of its mission-critical systems. It is doubtful that FAA can adequately do all of this in the time remaining. Accordingly, FAA must determine how to ensure continuity of critical operations in the likely event of some systems’ failures. In October 1997, we reported that while the Social Security Administration (SSA) had made significant progress in assessing and renovating mission-critical mainframe software, certain areas of risk in its Year 2000 program remained. Accordingly, we made several recommendations to address these risk areas, which included the Year 2000 compliance of the systems used by the 54 state Disability Determination Services that help administer the disability programs. SSA agreed with these recommendations and, in July 1998, we reported that actions to implement these recommendations had either been taken or were underway.Further, we found that SSA has maintained its place as a federal leader in addressing Year 2000 issues and has made significant progress in achieving systems compliance. However, essential tasks remain. For example, many of the states’ Disability Determination Service systems still had to be renovated, tested, and deemed Year 2000 compliant. Our work has shown that much likewise remains to be done in DOD and the military services. For example, our recent report on the Navy found that while positive actions have been taken, remediation progress had been slow and the Navy was behind schedule in completing the early phases of its Year 2000 program. Further, the Navy had not been effectively overseeing and managing its Year 2000 efforts and lacked complete and reliable information on its systems and on the status and cost of its remediation activities. We have recommended improvements to DOD’s and the military services’ Year 2000 programs with which they have concurred. In addition to these examples, our reviews have shown that many agencies had not adequately acted to establish priorities, solidify data exchange agreements, or develop contingency plans. Likewise, more attention needs to be devoted to (1) ensuring that the government has a complete and accurate picture of Year 2000 progress, (2) setting governmentwide priorities, (3) ensuring that the government’s critical core business processes are adequately tested, (4) recruiting and retaining information technology personnel with the appropriate skills for Year 2000-related work, and (5) assessing the nation’s Year 2000 risks, including those posed by key economic sectors.
