【正文】 zations wanting to be petitive.Section 2: IntroductionThe United States of America is branded as a Superpower when it es to military strength, but the context can indeed be wider. In practically all areas of human endeavor it stands on top: it has the largest GNP, biggest industrial and manufacturing base and an impressive, efficient and enviable scientific and technological infrastructure. Its output in as traditional an area as agriculture or in as modern a field as information technology is prodigious. It is not only a granary for the world but also a demonstration and proving ground for harnessing new technologies or innovations for creating wealth or improving the quality of life. Among the world’s 500 largest corporations, the magazine Fortune lists 151 as American owned, larger than any other country. In 1994 alone, these corporations earned a profit of more than $ 140 billion, a record among other petitors. As impressive as this is, it was actually better, especially after the Second World War and in the 1950s and 60s. Since then, this lead has eroded away in some key manufacturing industries such as iron and steel, automobiles and consumer electronics. Meanwhile, the deficit in trade balance in these areas between total value of exports and the total value of imports by the US has actually increased. Since the seventies, more areas have been lost to petition。Business Process Analysis A Letter from AmericaProfessor V.

American corporations visible to outsiders are generally very large, with annual budgets running well above the national budgets of many countries, and with a range of diverse operations transcending divisional, organisational and national barriers. In responding to changes in the global market place, they are continually introducing innovations in process and product technologies and in product development and manufacturing cycles. It is difficult to enumerate, let alone discuss, all the innovations that are seen in US business today. Instead, we shall focus on innovations that are significant and generic for improving business processes. This is relevant as more than fifty percent of US firms are medium or small sized, and the general petitiveness of US industry depends on them as well. In this report, we do not discuss the recent trends in financial, merger, ROD and marketing strategies and processes. Instead, we discuss only those issues related to business processes that impact the ability of US business to meet the identified market demands in cost, quality and time. A phrase, now increasingly in vogue, to describe the efforts in process improvements is Business Process Reengineering (BAR). Hammer and Champ define BAR as the radical rethinking of the business processes to achieve dramatic improvements in critical contemporary measures of performance as cost, quality and speed. This characterisation of reengineering is often interpreted in multiple ways resulting in different models and methods of implementation of business process reengineering. Reported failure rates of about forty to seventy percent for BAR applications in achieving stated goals can indeed be attributed to the differences in perceived definition of what constitutes reengineering and the level of implementation. In practice, implementations of reengineering span from reengineering local process to a plete restructuring the entire organisation. Business process reengineering for local improvements have led to the development of analytical models for optimisation of existing processes through simpler procedures and incorporation of Information technology. Activity based accounting, an American invention, is also used in conjunction with process reengineering projects efforts. The drive towards BAR in American industries has spawned an industry of consultants and process mapping and simulation tools. A brief review of the stateofthe art in analytical methods and tools such as IDEFO, SAT, BPMAT and Design Process Matrix is also provided in this report. At the other end, there are examples of well established organisational structures and processes being totally replaced by new structures and flexible processes. Such total re structuring efforts may well include use of cross functional teams, retraining and activities related to the management of innovation as integral parts of the business processes, well beyond the conventional activities of design, manufacture, and service of products. The difference between successful and unsuccessful firms that use BAR appears to lie more on the scope and coverage of the BAR efforts than on the mere application of tools and methods. We illustrate the above inferences by discussing the various models used by some US f
