T his paper describes a novel theoretical and empirical approach to tasks such as business process redesign and knowledge management. The project involves collecting examples of how different organizations perform similar processes, and organizing these examples in an on-line "process handbook." The handbook is intended to help people: (1) redesign existing organizational processes, (2) invent new organizational processes (especially ones that take advantage of information technology), and (3) share ideas about organizational practices.A key element of the work is an approach to analyzing processes at various levels of abstraction, thus capturing both the details of specific processes as well as the "deep structure" of their similarities. This approach uses ideas from computer science about inheritance and from coordination theory about managing dependencies. A primary advantage of the approach is that it allows people to explicitly represent the similarities (and differences) among related processes and to easily find or generate sensible alternatives for how a given process could be performed. In addition to describing this new approach, the work reported here demonstrates the basic technical feasibility of these ideas and gives one example of their use in a field study.
SummaryThis paper defines four basic business models based on what asset rights are sold (Creators, Distributors, Landlords and Brokers) and four variations of each based on what type of assets are involved (Financial, Physical, Intangible, and Human). Using this framework, we classified the business models of all 10,970 publicly traded firms in the US economy from 1998 through 2002. Some of these classifications were done manually, based on the firms' descriptions of sources of revenue in their financial reports; the rest were done automatically by a rule-based system using the same data. Based on this analysis, we first document important stylized facts about the distribution of business models in the U.S. economy. Then we analyze the firms' financial performance in three categories: market value, profitability, and operating efficiency. We find that no model outperforms others on all dimensions. Surprisingly, however, we find that some models do, indeed, have better financial performance than others. For instance, PhysicalCreators (which we call Manufacturers) and Physical Landlords have greater cash flow on assets, and Intellectual Landlords have poorer q's, than Physical Distributors (Wholesaler/Retailers),. These findings are robust to a large number of robustness checks and alternative interpretations. We conclude with some hypotheses to explain our findings.Running head: Do Some Business Models Perform Better than Others?
In this paper, we propose a genre taxonomy as a knowledge repository of communicative structures or "typified actions" enacted by organizational members. The Genre taxonomy aims at helping people to make sense of diverse types of communicative actions, and has three features to achieve this objective. First, the genre taxonomy represents the elements of both genres and genre systems, sequences of interrelated genres, as embedded in a social context considering the "5W1H" questions (Why, What, Who/Whom, When, Where, and How). In other words, the genre taxonomy represents the elements of both genres and genre systems in terms of purpose, contents, participants, timing of use, place of communicative action, and form including media, structuring devices and linguistic elements. Second, the genre taxonomy represents both widely recognized genres such as a report and specific genres such as a technical report used in a specific company, because the difference between a widely recognized genre and a specific variant based on the more general genre sheds light on the context of genre use. Third, the genre taxonomy represents use and evolution of genre over time to help people to understand how a genre is relevant to a community where the genre is enacted and changed.We have constructed a prototype of such a genre taxonomy using the Process Handbook, a process knowledge repository developed at MIT. We have included both widely recognized genres such as the memo and specific genres such as those used in the Process Handbook itself. We suggest that this genre taxonomy may be useful in the innovation of new document templates or methods for communication because it helps to clarify different possible uses of similar genres and explicates how genres play a coordination role among people and between people and their tasks.
Abstract:There has been a lot of research addressing the relationship between Information Technology (IT) 1 The authors would like to mention that this paper would not have been possible without the guidance and insights of Prof. Thomas W. Malone. He was the PI in a CMI research grant that funded most of the work here described. He has contributed a lot of his time while following the research from day one and providing copious detailed comments on various drafts of this paper.
