Information Technologies and Business Value: An Analytic and Empirical Investigation

An important management question today is whether the anticipated economic benefits of Information Technology IT are being realized. In this paper, we consider this problem to be measurement related, and propose and test a new process-oriented methodology for ex post measurement to audit IT impacts on a strategic business unit SBU or profit centers performance. The IT impacts on a given SBU are measured relative to a group of SBUs in the industry. The methodology involves a two-stage analysis of intermediate and higher level output variables that also accounts for industry and economy wide exogenous variables for tracing and measuring IT contributions. The data for testing the proposed model were obtained from SBUs in the manufacturing sector. Our results show significant positive impacts of IT at the intermediate level. The theoretical contribution of the study is a methodology that attempts to circumvent some of the measurement problems in this domain. It also provides a practical management tool to address the question of why or why not certain IT impacts occur. Additionally, through its process orientation, the suggested approach highlights key variables that may require managerial attention and subsequent action.

Understanding the service component of application service provision: empirical analysis of satisfaction with ASP services

In spite of the promise and potential of improving the way organizations develop, operate and maintain information technology (IT) applications, application service providers (ASPs) have fared poorly in terms of attracting a large client base. Anecdotal evidence in the business press points to limited satisfaction among users of ASP, which calls for an assessment of determinants of satisfaction with ASP. In this paper, we draw upon the consumer satisfaction paradigm widely employed in marketing literature to analyze post-usage satisfaction with ASP services. We develop a conceptual model of satisfaction with ASP and empirically test the predictions using data from 256 firms using ASP services. Expectations about ASP service have a significant influence on the performance evaluation of ASPs, and experience-based norms have only limited significance in explaining satisfaction with ASP. We also find empirical support for the influence of performance and disconfirmation on the satisfaction with ASP. Implications for both ASPs and organizations adopting ASP services are discussed.

The Calculus of Reengineering

Advances in new Information Technologies IT and changes in the business environment such as globalization and competitive pressure have prompted organizations to embark on reengineering projects involving significant investments in IT and business process redesign. However, the evidence of payoff from such investments can be classified as mixed as best, a problem we partly attribute to the absence of a strong theoretical foundation to assess and analyze reengineering projects. We seek to apply complementarity theory and a business value modeling approach to address some questions involving what, when, and how much to reengineer. Complementarity theory is based on the notion that the value of having more of one factor increases by having more of another complementary factor. Further, related developments in the optimization of “supermodular” functions provide a useful way to maximize net benefits by exploiting complementary relationships between variables of interest. Combining this theory with a multi-level business value model showing relationships between key performance measures and their drivers, we argue that organizational payoff is maximized when several factors relating to IT, decision authority, business processes and incentives are changed in a coordinated manner in the right directions by the right magnitude to move toward an ideal design configuration. Our analysis further shows that when a complementary reengineering variable is left unchanged either due to myopic vision or self-interest, the organization will not be able to obtain the full benefits of reengineering due to smaller optimal changes in the other variables. We also show that by increasing the cost of changing the levels of design variables, unfavorable pre-existing conditions e.g., too much heterogeneity in the computing environment can lead to reengineering changes of smaller magnitude than in a setting with favorable conditions.

An empirical analysis of the impact of information capabilities design on business process outsourcing performance

Organizations today outsource diverse business processes to achieve a wide variety of business objectives ranging from reduction of costs to innovation and business transformation. We build on the information processing view of the firm to theorize that performance heterogeneity across business process outsourcing (BPO) exchanges is a function of the design of information capabilities (IC) that fit the unique information requirements (IR) of the exchange. Further, we compare performance effects of the fit between IR and IC across dominant categories of BPO relationships to provide insights into the relative benefits of enacting such fit between the constructs. Empirical tests of our hypotheses using survey data on 127 active BPO relationships find a significant increase (decrease) in satisfaction as a result of the fit (misfit) between IR and IC of the relationship. The results have implications for how BPO relationships must be designed and managed to realize significant performance gains. The study also extends the IPV to identify IC that provide the incentives and means to process information in an interfirm relationship.

Antecedents and Consequences of Internet Use in Procurement: An Empirical Investigation of U.S. Manufacturing Firms

This paper examines the antecedents and consequences of Internet use in the procurement process. Drawing upon the resource-based view (RBV) of the firm and the technology, organization, and environment framework, we develop an integrative model that examines the antecedents and consequences of Internet use in two stages---the search stage and the order initiation and completion (OIC) stage---of the procurement process. The model enables us to deconstruct both the usage and the performance aspects of information technology (IT) in business processes, and to provide insights into the enablers of use and business value. The model is estimated with survey data from 412 firms. Our results suggest that while some resources, such as procurement-process digitization, influence Internet use in both the procurement stages, other resources, such as the diversity of organizational procurement knowledge, impact Internet use in only one stage. We also find that Internet use in the OIC stage has a more significant impact on procurement-process performance than use in search. This study extends the digital capabilities and firm performance literature in the context of electronic procurement. This study also contributes to the small but emerging stream of literature that investigates antecedents, the extent, and implications of IT use holistically.

An economic analysis of strategic information technology investments

The information systems literature is replete with conceptual frameworks for analyzing strategic applications of information technology (IT). In this article, the strategic impacts of IT investment are studied through the development of a formal economic model. In particular, it focuses on IT-related quality competition in a duopoly, where the services may not be priced initially (e.g., in the financial services sector), and where the benefits may come indirectly (e.g., in the form of interest earned on consumer deposits or float on checking accounts). A firm may have to invest in IT, regardless of its underlying cost structure, as a response to its competitors investment level. (We analyze the division of technology benefits between the firms and the consumers and study welfare implications for simultaneous and sequential investments.) Both firms prefer sequential over simultaneous investments, even when both have the required technology. While the IT-inefficient firm (one with higher IT cost for a given service quality) has followership incentives, the leadership incentives for the IT-efficient firm depend on the difference in IT cost structures and the degree of substitutability between the services of the two firms. A preliminary treatment of pricing issues is provided in conjunction with consumer switching cost, which not only has a negative impact on consumer welfare but may also reduce total industry profits. For dynamic markets with new consumers, the negative effect of switching cost on th welfare of existing consumers is reduced when the IT-efficient firm moves first.

An Economic Analysis of the Introduction of an Electronic Data Interchange System

Although electronic data interchange EDI holds the promise of significantly increasing the efficiency of business transactions, an installed base of proprietary implementations has been detrimental to the widespread acceptance of the technology. Thus, an important research issue involves strategies for facilitating EDI adoption. We analyze the introduction of an EDI system in a vertical market involving one manufacturer and two suppliers. The manufacturer initiates an EDI network, and penalizes a supplier for not joining the system by reducing its volume of business with the supplier. Along with a “stick,” the manufacturer can also use a “carrot” in the form of a subsidy to partially offset a suppliers setup cost. The competition between the suppliers is characterized by incentive types for joining the EDI system “motivating” or “threatening” and the Information Technology IT efficiency “efficient” or “inefficient”. We show that regardless of its cost structure, a supplier may have to join the EDI network out of “strategic necessity,” due to the presence of an IT-efficient supplier. Our analysis further shows that depending on the supplier competition structure, the EDI system may prove to be a “beneficial” strategic necessity for a large supplier and an “unfortunate” strategic necessity for a small supplier. Another key result is that by increasing the severity of the penalty, both the manufacturer and the follower supplier can be worse off under certain conditions. The analysis of subsidy strategies reveals that unless leadership and followership positions are reversed due to a subsidy, subsidizing a supplier has no impact on the joining time of its competitor. Thus the EDI initiator cannot induce both suppliers to join earlier by subsidizing one supplier. Also, the larger the slack capacity of the leader, the higher lower the manufacturers incentive to subsidize the leader follower. These results offer insights for initiators and adopters regarding penalty and subsidy strategies, impact on competition structure, joining decisions and network growth.

An integrated assessment of productivity and efficiency impacts of information technology investments: Old data, new analysis and evidence

We reexamine the •Information Technology (IT) productivity paradox• from the standpoints of theoretical basis, measurement issues and potential inefficiency in IT management. Two key objectives are: (i) to develop an integrated microeconomic framework for IT productivity and efficiency assessment using developments in production economics, and (ii) to apply the framework to a dataset used in prior research with mixed results to obtain new evidence regarding IT contribution. Using a stochastic frontier with a production economics framework involving the behavioral assumptions of profit maximization and cost minimization, we obtain a unified basis to assess both productivity and efficiency impacts of IT investments. The integrated framework is applied to a manufacturing database spanning 1978–1984. While previous productivity research with this dataset found mixed results regarding the contribution from IT capital, we show the negative marginal contribution of IT found in an important prior study is attributable primarily to the choices of the IT deflator and modeling technique. Further, by ignoring the potential inefficiency in IT investment and management, studies that have reported positive results may have significantly underestimated the true contribution of IT. This positive impact of IT is consistent across multiple model specifications, estimation techniques and capitalization methods. The stochastic production frontier analysis shows that while there were significant technical, allocative and scale inefficiencies, the inefficiencies reduced with an increase in the IT intensity. Given that the organizational units in our sample increased their IT intensity during the time period covered by the study, management was taking a step in the right direction by increasing the IT share of capital inputs. Our results add to a small body of MIS literature which reports significant positive returns from IT investments.

An electronic infrastructure for a virtual university

ith dramatic advances in networking technologies, distance education has taken on a new meaning that emphasizes interactivity in learning. However, computer networks are primarily designed for distributing content. What was once printed on paper and sent through postal mail can now be delivered through electronic mailing lists or the World-Wide Web. While this new electronic approach increases distribution efficiency, it does not exploit the full potential of the technology as an enabler of a reengineering of the educational process itself [5]. This article is about the Electronic Education Environment, or E3, an infrastructure developed at The University of Texas at Austin to support processes in a virtual university (VU). A VU does not have a traditional campus, professors’ offices, or a library; instead, there are electronic workspaces and global libraries that provide richer functionality and features than their physical analogs. A VU focuses on developing skills and expertise by mass customizing content on demand rather than providing terminal degree programs with homogeneous and predetermined curricula. A VU consists of an administrative body, instructors, content providers, content reviewers/validators, and students connected through an open electronic infrastructure with appropriate control mechanisms. Instructors and reviewers may be affiliated with multiple VUs and render services on demand. Content providers are dispersed globally, chosen to match specific demands. The E3 infrastructure consists of many components, including a collaboratory [1], a payment system, and a document filtering system. The collaboratory component has been used for the last several semesters (beginning fall 1995) and other components are being tested with more 150 students in the School of Business at The University of Texas at Austin.

The Information Technology Productivity Paradox Revisited: A Theoretical and Empirical Investigation in the Manufacturing Sector

The lack of empirical support for the positive economic impact of information technology (IT) has been called the IT productivity paradox. Even though output measurement problems have often been held responsible for the paradox, we conjecture that modeling limitations in production-economics-based studies and input measurement also might have contributed to the paucity of systematic evidence regarding the impact of IT. We take the position that output measurement is slightly less problematic in manufacturing than in the service sector and that there is sound a priori rationale to expect substantial productivity gains from IT investments in manufacturing and production management. We revisit the IT productivity paradox to highlight some potential limitations of earlier research and obtain empirical support for these conjectures. We apply a theoretical framework involving explicit modeling of a strategic business units (SBU)1 input choices to a secondary data set in the manufacturing sector. A widely cited study by Loveman (1994) with the same dataset showed that the marginal contribution of IT to productivity was negative. However, our analysis reveals a significant positive impact of IT investment on SBU output. We show that Lovemans negative results can be attributed to the deflator used for the IT capital. Further, modeling issues such as a firms choice of inputs like IT, non-IT, and labor lead to major differences in the IT productivity estimates. The question as to whether firms actually achieved economic benefits from IT investments in the past decade has been raised in the literature, and our results provide evidence of sizable productivity gains by large successful corporations in the manufacturing sector during the same time period.
