A recent National Research Council workshop on the economic and social impacts of information technology noted that information technologies rarely have consistent effects on the performance of groups or organizations, largely because outcomes are highly conditioned by the social and behavioral characteristics of the environments in which they are implemented (NRC, 1998~. For example, the R&D headquarters of a global pharmaceutical firm introduced a groupware tool to facilitate the sharing of early experimental results among researchers as part of a major effort to reduce R&D cycle time (Ciborra and Patriotta, 1996~.

The 777 design process involved 4,500 engineers, about 200 design-build teams, six design partners, 3 million parts, two versions of CATIA, more than 350 Boeing-developed application programs, and more than 150,000 CATIA models. Because of the huge investment required to implement the new engineering processes used with the 777, the new processes did not reduce development costs compared to traditional methods.

In some cases, AEE technologies seem to be spreading primarily through informal, personal contacts by midlevel managers rather than as a result of implementation plans approved by high-level Center managers. The Collaborative Engineering Environment element of the ISE functional initiative is using an evolutionary approach to deploy AEE technology and improve NASA's near-term capabilities.

The initiative is applying the high-performance computing capability developed under the Accelerated Strategic Computing Initiative to nondefense purposes.9 The Scientific Simulation Initiative will include R&D on human-centered computing technology to improve interactions associated with problem definition and visualization of results. Additional information on collaborative efforts, including some of those mentioned above, is available via the Internet as indicated in Table 2-2.

ADVANCED ENGINEERING ENVIRONMENTS TABLE 2-3 Imperatives from the Next-Generation Manufacturing Project Workforce/workplace flexibility, which is provided by a new set of practices, policies, processes, and culture that enables the employee to feel a sense of security and ownership, while enabling a company to capitalize on the creativity, commitment, and discretionary effort of its employees and, at the same time, maintain the flexibility to continually adjust the size and skills of the workforce Knowledge supply chains, which radically improve the supply and dissemination of knowledge throughout manufacturing organizations by applying concepts of supply-chain management to the relationships between industry, universities, schools, and associations Rapid product and process realization, which enables all stakeholders to participate concurrently in the design, development, and manufacturing process Management of innovation, which includes both initial creativity and the successful implementation of new concepts Management of change, which applies deliberate change to the current state of an organization to achieve a more competitive future state Next-generation manufacturing processes and equipment, which are facilitated by a growing knowledge base of the science of manufacturing and used to rapidly adapt to specific production needs Pervasive modeling and simulation, which enable virtual production and allow production decisions to be made on the basis of modeling and simulation methods rather than on build-and-test methods Adaptive, responsive information systems, which can be reshaped dynamically into new systems by adding new elements, replacing others, and changing how modules are connected to redirect data flows through the total system Collaboration among extended enterprises, which are formed by the seamless integration of a group of companies, suppliers, educational organizations, and government agencies to create a timely and costeffective service or product Integration of enterprises to connect and combine people, processes, systems, and technologies and ensure that the right information is available at the right location, with the right resources, at the right time Source: NGM, 1997 OBSERVATIONS ON THE CURRENT STATE OF THE ART Based on its selective review of current ABE activities. the committee made the following general observations: The challenge of tool and system integration is ubiquitous.
