The New Industrial Engineering: Information Technology and Business Process Redesign
Those aspiring to improve the way work is done must begin to apply the capabilities of information technology to redesign business processes. Business process design and information technology are natural partners, yet industrial engineers have never fully exploited their relationship. The authors argue, in fact, that it has barely been exploited at all. But the organizations that have used IT to redesign boundary-crossing, customer-driven processes have benefited enormously. This article explains why.
At the turn of the century, Frederick Taylor revolutionized the workplace with his ideas on work organization, task decomposition, and job measurement. Taylor’s basic aim was to increase organizational productivity by applying to human labor the same engineering principles that had proven so successful in solving the technical problems in the work environment. The same approaches that had transformed mechanical activity could also be used to structure jobs performed by people. Taylor came to symbolize the practical realizations in industry that we now call industrial engineering (IE), or the scientific school of management.1 In fact, though work design remains a contemporary IE concern, no subsequent concept or tool has rivaled the power of Taylor’s mechanizing vision.
As we enter the 1990s, however, two newer tools are transforming organizations to the degree that Taylorism once did. These are information technology–the capabilities offered by computers, software applications, and telecommunications–and business process redesign–the analysis and design of work flows and processes within and between organizations. Working together, these tools have the potential to create a new type of industrial engineering, changing the way the discipline is practiced and the skills necessary to practice it.
This article explores the relationship between information technology (IT) and business process redesign (BPR). We report on research conducted at MIT, Harvard, and several consulting organizations on nineteen companies, including detailed studies of five firms engaged in substantial process redesign. After defining business processes, we extract from the experience of the companies studied a generic five-step approach to redesigning processes with IT. We then define the major types of processes, along with the primary role of IT in each type of process. Finally, we consider management issues that arise when IT is used to redesign business processes.
IT in Business Process Redesign
The importance of both information technology and business process redesign is well known to industrial engineers, albeit as largely separate tools for use in specific, limited environments.2 IT is used in industrial engineering as an analysis and modeling tool, and IEs have often taken the lead in applying information technology to manufacturing environments. Well-known uses of IT in manufacturing include process modeling, production scheduling and control, materials management information systems, and logistics.

Loveman, "An Assessment of the Productivity Impact of Information Technologies" (Cambridge, Massachusetts: MIT Sloan School of Management, Management in the 1990s, Working Paper 90s:88–054, July 1988). Loveman studied microeconomic data from manufacturing firms to estimate econometrically the productivity impact of IT in the late 1970s and early 1980s. In finding no significant positive productivity impact from IT, he argues that his findings in manufacturing raise serious questions about impacts in nonmanufacturing firms as well.
Baily and Chakrabarti (1988) studied white-collar productivity and IT as one part of a broader inquiry into poor productivity growth. They found no evidence of significant productivity gain. See M.N. Baily and A. Chakrabarti, Innovation and the Productivity Crisis (Washington, D.C.: Brookings Institution, 1988).

6. Robert Horton, who became chairman and chief executive of British Petroleum in March 1990, argues that his major concern in setting BP's course in the next decade is "managing surprise." Horton's belief is that the external business environment is so unpredictable that surprise, rather than managed change, is inevitable. See R. Horton, "Future Challenges to Management," MIT Management, Winter 1989, pp. 3–6.

16. Information engineering and other redesign approaches based on data modeling are necessarily limited in scope. More than data is exchanged in many process relationships. Note too that many companies have used information engineering methods without a specific process orientation.

29. One might consider managerial processes synonymous with informational processes. Certainly the vast majority of managerial processes, such as budgeting, planning, and human resource development, involve informational objects. Yet it is important to remember that informational processes can be either operational or managerial, so we believe that this separate dimension of process types is warranted.
