MAKING IT BETTER: EXPANDING INFORMATION TECHNOLOGY RESEARCH TO MEET SOCIETY'S NEEDS Preface The United States enjoys an enviable position in the Information Age. The nation's information technology (IT) industry is thriving, and virtually every facet of society has been influenced by it. Indeed, IT is transforming a large—and growing—portion of the nation's economic and personal activities. As a result, IT-related issues are of interest to a widening circle of users, not just the vendors of IT products and services. These obvious trends do not, however, ensure continued progress in IT and its applications because they do not indicate whether sufficient investments are being made in IT research. As previous reports by the Computer Science and Telecommunications Board (CSTB) of the National Research Council demonstrate,1 the nation's leadership in the development and application of IT derives in large part from an effective program of research that has been conducted and managed jointly by industry, universities, and government since the end of World War II. Today's IT systems continue to draw on the knowledge base constructed by research conducted over the past five decades. 1   The role of federal research funding in the innovation process has been examined in two CSTB reports: Computer Science and Telecommunications Board, National Research Council. 1995. Evolving the High Performance Computing and Communications Initiative to Support the Nation's Information Infrastructure. National Academy Press, Washington, D.C.; Computer Science and Telecommunications Board, National Research Council. 1999. Funding a Revolution: Government Support for Computing Research.

MAKING IT BETTER: EXPANDING INFORMATION TECHNOLOGY RESEARCH TO MEET SOCIETY'S NEEDS Continued leadership and innovation in IT—and the continued flow of societal benefits that derive from such leadership—depend on suitable investments in IT research today and in the future. A critical examination is needed to define the kinds of research investment needed for the early twenty-first century, a time when IT will play a much more prominent role than it did in the second half of the twentieth century, when most of today's IT capabilities and expectations were built. THE COMMITTEE AND ITS CHARGE To improve understanding of these issues and help guide future endeavors, the National Science Foundation (NSF) asked CSTB to conduct a study of IT research that would examine ongoing trends in industry and academic research, determine the possible effects of those trends on the well-being of the nation's IT industry and the nation as a whole, and explore options for strengthening the research base, if necessary. Of particular interest is support for research that advances our fundamental understanding of capabilities, architectural designs, and principles that can have a pervasive influence on innovation throughout the IT industry (called “fundamental research” in this report) rather than advancing a single product, process, or service (called “applied research” in this report).2 Is the nation investing sufficient resources in the types of research that will ensure its capability to innovate in the future, or have research investments become more narrowly targeted to near-term efforts? Representative issues include the following:3 Trends in IT research and development spending. What trends in computing and communications industry research and development (R&D) spending can be documented, and at what level of detail? How has support for fundamental and more targeted research programs shifted? Is the overall level of effort sufficient? The scope of IT research. Are the scope and scale of computing and communications R&D changing? Is IT research sufficiently broad to 2   The federal government tends to classify research as either “basic” or “applied.” There is some correspondence between these terms and the terminology used in this report, as described in greater detail in Chapter 1. 3   The original concept for the study also included attention to international issues, in particular, the relative position of U.S. research efforts in IT compared with those of other countries. As the project unfolded, issues of international competitiveness became less of a motivational factor. The growth of the Internet and U.S. IT industries led to a perception that the greatest threats to the nation's IT base were not external, but internal—the lack of fundamental understanding of large-scale systems and their broad range of societal applications.

MAKING IT BETTER: EXPANDING INFORMATION TECHNOLOGY RESEARCH TO MEET SOCIETY'S NEEDS address new challenges resulting from the convergence of computing and communications? Are government, universities, and industry well organized to conduct research across disciplinary boundaries? Changes in private-sector support for research. How do major technology market trends, such as the growing emphasis on and pervasiveness of network-based systems, affect private sector R&D investments? How do computing and communications companies of different sizes and types make R&D decisions, and how have the decision processes and outcomes been changing? Mechanisms for strengthening IT research. What are some promising approaches to filling in gaps in the research portfolio and/or sustaining the flow of R&D? Is the government investment adequate? What types of institutional approaches might be the focus of experimentation? What factors, structures, and mechanisms enable success in research collaborations? To conduct the study, CSTB assembled a committee of 16 members with expertise in the IT industry, IT research, applications of IT in government and industry, the organization of IT research, and federal support for research. Members were drawn from both industry and academia and brought with them technical expertise in computing, communications, software, and devices. Several committee members had experience with federal research programs and backgrounds in economics and public policy. The committee met five times between July 1997 and August 1998 to plan its course of action, solicit testimony from relevant experts, deliberate over its findings, and draft its final report. It continued its work by electronic communications throughout 1999 and into the beginning of 2000. During the course of the project, the committee heard from researchers and research managers in industry and universities and from directors of government agencies involved in funding computing research. It met with engineers involved in the development and deployment of sophisticated information systems for clients in a range of fields. The committee also gathered available statistics on IT research investments in the public and private sectors. These data have a number of limitations (as described in this report) so they could not by themselves provide definitive insight into trends in IT research. Accordingly, the committee supplemented the data with information provided by its members and by those who briefed the committee. This range of input was used to develop the conclusions and recommendations contained in the report. The unusually long time it took the committee to do its work reflects the challenges involved in integrating diverse inputs and perspectives and in shaping a contribution to the rapidly evolving national debate about IT and IT research.

MAKING IT BETTER: EXPANDING INFORMATION TECHNOLOGY RESEARCH TO MEET SOCIETY'S NEEDS During the committee's working period, a number of important developments took place that were factored into the committee's conclusions. Most notably, an advisory committee authorized by the High Performance Computing and Communications Act of 1991 and encouraged by earlier CSTB reports was finally established in 1997, albeit in a form tailored to suit the times: the President's Information Technology Advisory Committee (PITAC). The CSTB study committee and PITAC shared one common member (Irving Wladawsky-Berger), but the work of the two committees proceeded independently, preserving the CSTB committee's ability to offer its own perspective and comment on PITAC's work. The CSTB committee reviewed the interim and final reports from PITAC, as well as information on the Clinton Administration's Information Technology Research initiative (originally constituted as Information Technology for the Twenty-First Century, or IT2) and ongoing federal programs, ensuring that the present report would be relevant to the evolving environment for federal support of IT research. Similarities between the main conclusions of this report and the PITAC report, which were arrived at independently, reflect a degree of consensus within the field regarding the research base for IT. Although it attempted to complement the work of PITAC, the CSTB committee differentiated itself by (1) concentrating on two specific areas that it deemed to be of great importance to the nation and also insufficiently addressed by ongoing IT research initiatives and (2) relating its substantive research recommendations to an assessment of trends and supportive mechanisms for IT research. Rather than compete with PITAC or duplicate its work, the committee monitored the reception given to PITAC's recommendations and attempted to address questions that were raised about their rationale. The resulting report is a vehicle for maintaining the momentum imparted by PITAC—which itself drew on the evolution of thinking and programs throughout the 1990s—and for furthering the realignment of IT research to which PITAC and others have contributed. It draws on the work of other CSTB committees, which have looked in great detail at a number of specific components of the IT research arena and developed recommendations for IT research (both its substance and process) related to those components. Finally, the committee strove to present its conclusions in a form consistent with its intention to target the report at a broad, high-level audience, including policymakers, research managers in government and industry, corporate executives, and the research community. ACKNOWLEDGMENTS As with any project of this magnitude, thanks are due to the many individuals who contributed to the work of the committee. First, thanks

Rycroft (George Mason University); David Tennenhouse (then with DARPA, now with Intel Corporation); and Gilbert Weigand (then with the Department of Energy). Others also provided valuable assistance to the committee behind the scenes. Raymond Wolfe at the NSF provided detailed statistics on industry R&D spending and answered numerous questions about the data. Elinor Champion, Andrew Hildreth, Nelson Lim, Janet Shapiro, Mary Streitwieser, and Ron Taylor at the Census Bureau helped committee members and staff navigate the process of accessing detailed data on corporate R&D spending. Hoyle Curtis provided information on research expenditures at Hewlett-Packard Co. Jed Gordon, an undergraduate in the Science, Technology, and Society program at the Massachusetts Institute of Technology, worked with the CSTB during the summers of 1997, 1998, and 1999, collecting and analyzing corporate expenditures on R&D, writing summaries of his investigations, and conducting a wide range of related research and writing assignments. As she has done so many times in the past, Laura Ost, a free-lance editor, provided invaluable assistance in preparing the final manuscript under incredibly tight deadlines.
