Research Collection School Of Computing and Information Systems
New technological innovations have made it possible for new intermediaries to create value in business processes that involve the procurement of manufacturing and services supplies. Associated with these innovations is the emergence of business-to-business (B2B) electronic markets. These act as digital intermediaries that aim to reduce the transaction costs and mitigate the risks inherent in procurement. They improve buyers’ capabilities to search for attractive prices and also serve to increase the liquidity of sellers’ products. In this chapter, the authors explore the evolution of B2B e-market firms in terms of the strategies they employ to “perfect” their value propositions and …

Technology Competition And Optimal Investment Timing: A Real Options Perspective, Robert J. Kauffman, X. Li
Technology Competition And Optimal Investment Timing: A Real Options Perspective, Robert J. Kauffman, X. Li
Research Collection School Of Computing and Information Systems
Companies often choose to defer irreversible investments to maintain valuable managerial flexibility in an uncertain world. For some technology-intensive projects, technology uncertainty plays a dominant role in affecting investment timing. This article analyzes the investment timing strategy for a firm that is deciding about whether to adopt one or the other of two incompatible and competing technologies.We develop a continuous-time stochastic model that aids in the determination of optimal timing for managerial adoption within the framework of real options theory. The model captures the elements of the decision-making process in such a way so as to provide managerial guidance in …

Despite the huge investments by organizations in ERP implementation, maintenance, and user training, ERP implementation failures and less-than-satisfactory productivity improvements are common. End-users’ reluctance or unwillingness to adopt or use the newly implemented ERP system is often cited as one of the main reasons for ERP failures. To examine factors leading to the lack of end-user acceptance of ERP systems, we reviewed the literature on user adoption of IT in mandatory contexts, developed hypotheses to explain ERP user acceptance, and conducted a survey study to test the hypotheses. In particular, we examined end-users’ attitudes toward system use and symbolic adoption, …

Proprietary And Open Systems Adoption In E-Procurement: A Risk-Augmented Transactions Cost Perspective, Robert J. Kauffman, Hamid Mohtadi
Proprietary And Open Systems Adoption In E-Procurement: A Risk-Augmented Transactions Cost Perspective, Robert J. Kauffman, Hamid Mohtadi
Research Collection School Of Computing and Information Systems
We present an economic model that enables the study of incentives for business-to-business (B2B) e-procurement systems investments that permit inventory coordination and improved operational control. We focus on the information technology adoption behavior of firms in the presence of transaction costs, agency costs and information uncertainty. We conclude that it is appropriate to rethink the prior theory and develop an extended transaction-cost theory perspective that incorporates the possibility of shocks. We distinguish among three kinds of B2B e-procurement systems platforms. Proprietary platform procurement systems involve traditional electronic data interchange (EDI) technologies. Open platform procurement systems are associated with e-market Web …
A Cost-Effective Critical Path Approach For Service Priority Optimization In The Grid Computing Economy, Mei Lin, Zhangxi Lin
A Cost-Effective Critical Path Approach For Service Priority Optimization In The Grid Computing Economy, Mei Lin, Zhangxi Lin
Research Collection School Of Computing and Information Systems
The advancement in the utilization and technologiesof the Internet has led to the rapid growth of gridcomputing; and the perpetuating demand for gridcomputing resources calls for an incentive-compatible solution to the imminent QoS problem. This paper examines the optimal service priority selection problem that a grid computing network user will confront. We model grid services for a multi-subtask request as a prioritized PERT graph and prove that the localized conditional critical path, which is based on the cost-minimizin gpriority selection for each node, sets the lower bound for the length of cost-effective critical path that commits the optimal solution. We …

Modeling Product Development As A System Design Game, C. Jason Woodard
Modeling Product Development As A System Design Game, C. Jason Woodard
Research Collection School Of Computing and Information Systems
A system design game is a model of a situation in which agents’ actions determine the structure of a system, which in turn affects the system’s value and the share of value that each agent may capture through bargaining or market competition. This paper describes a class of games in which agents design interdependent products, for example software programs, which may be complements or substitutes for each other. These relationships are epresented by an object called a design structure network (DSN). Depending on the modeler’s choice of allocation rules, agents may benefit from owning critical nodes in the DSN, corresponding …

Leadership Antecedents Of Informal Knowledge Acquisition And Dissemination, Siu Loon Hoe, Steve Mcshane
Research Collection School Of Computing and Information Systems
Knowledge management is emerging as one of the leading influences on an organisation’s survival and competitive advantage (Blumentritt & Johnston 1999). Knowledge management is concerned with the effective acquisition, sharing, storage and utilisation of knowledge (Huber 1991; Saffady 1998). Corporate leaders are increasingly aware of the notion that an organisation’s long-term survival depends on its ability to generate new knowledge and continuously learn from the environment. The importance of a superior organisational learning capability as a source of competitive advantage is a common refrain among both managers and scholars (e.g. Kohli & Jaworski 1990; Nonaka 1991; Quinn 1992; Slater & …

Community Banking In The E-Business Era, Peter Southard, Keng Siau
Research Collection School Of Computing and Information Systems
This paper reviews how existing and potential uses of Internet technology can generate a competitive advantage for rural community banks. To do so, it offers a framework for analyzing Internet technology investment decisions. Organizations in this segment of the banking industry are often more removed from centers of technology and have traditionally been more conservative in their approaches to information technology (among other things). Banking Associations have developed in the U.S., such as the Independent Bankers Association, to try and help community banks coordinate marketing, legislative, and other issues that they have in common. The use of Internet technology can …

Business and information systems (IS) executives continue to grapple with issues of risk and uncertainty in evaluating investments in information technology (IT). Despite the use of net present value (NPV) and other investment appraisal techniques, executives are often forced to rely on instinct when finalizing IT investment decisions. Recognizing the shortcomings of NPV, real options analysis has been suggested as an alternative approach, one that considers the risks associated with an investment while recognizing the ability of corporations to defer an investment until a later period or to make a partial investment instead. Responding to a growing interest in real …

Knowledge Sharing With Customers On The Www: Approaches By National Tourism Organizations, Xinran You, Joseph O'Leary, Fiona Fui-Hoon Nah
Research Collection School Of Computing and Information Systems
The importance of knowledge management has been emphasized increasingly in recent literature. Knowledge has been regarded as the most important corporate asset in an organization (Nonaka and Takeuchi, 1995). But what is knowledge? According to Harris (1996), "when information is combined with context and experience, it becomes knowledge". Hence, knowledge is the integration of information, context, and experience (Ponelis and Fairer-Wessels, 1998). In the tourism context of this paper, there are two components of knowledge: (1) customer knowledge--understanding of customers by marketers that leads to more effective marketing actions; and (2) destination knowledge that either the travelers or travel experts …

Do big dollar expenditures on information systems pay off? Friction-free: is that what we really want markets to be? Is it time for consumers to say goodbye to fixed pricing? The Internet creates an environment in which the cost of buyer-seller interactions is cheaper than ever, and consumers can participate in the price-setting process—revealing their willingness to pay—making it the most efficient one-on-one selling environment anywhere, approaching the efficiency of the financial markets. In fact, such transformation is evident throughout the information economy. We see it in the approximately 1,000% annual network growth rates expected by some Internet service providers’ …

Using Expert Support And Its Explanation Facilities For Group Decision Making, Fiona Fui-Hoon Nah, Izak Benbasat
Research Collection School Of Computing and Information Systems
As information technology is increasingly used to support group work, it becomes desirable to identify the types of computer-based decision aids that are beneficial for supporting group decision making. In a review of the decision support literature, Benbasat, DeSanctis and Nault (1993) point out the lack of empirical research in examining the use of expert support for group decision making. In our review of the literature in this respect, we identified only one case study (Sviokla, 1989), which examined the processes involved in the pre- and post-use of an expert support system (ESS) called PlanPower by a group of financial …
Exceptions And Exception Handling In Computerized Information Processes, Diane M. Strong, Steven M. Miller
Exceptions And Exception Handling In Computerized Information Processes, Diane M. Strong, Steven M. Miller
Research Collection School Of Computing and Information Systems
Exceptions, situations that cannot be correctly processed by computer systems, occur frequently in computer-based information processes. Five perspectives on exceptions provide insights into why exceptions occur and how they might be eliminated or more efficiently handled. We investigate these perspectives using an in-depth study of an operating information process that has frequent exceptions. Our results support the use of a total quality management (TQM) approach of eliminating exceptions for some exceptions, in particular, those caused by computer systems that are poor matches to organizational processes. However, some exceptions are explained better by a political system perspective of conflicting goals between …

Deterministic Approximations To Co-Production Problems With Service Constraints And Random Yields, Gabriel R. Bitran, Thin Yin Leong
Deterministic Approximations To Co-Production Problems With Service Constraints And Random Yields, Gabriel R. Bitran, Thin Yin Leong
Research Collection School Of Computing and Information Systems
Production planning problems where multiple item categories are produced simultaneously are examined. The items have random yields and are used to satisfy the demands of many products. These products have specification requirements that overlap. An item originally targeted to satisfy the demand of one product may be used to satisfy the demand of other products when it conforms to their specifications. Customers' demand must be satisfied from inventory. The problem is formulated with service constraints and a near-optimal solution is provided to the problem with a fixed planning horizon. Simple heuristics are proposed for the problem solved with a rolling …

Yet delivering such applications creates a bottleneck in software development activities. This dilemma can be addressed when firms shift to development methods that emphasize software reusability. This article examines the productivity implications of object and repository-based integrated computer-aided software engineering (ICASE) software development in the context of a major investment bank's information systems strategy. The strategy emphasizes software reusability. Our empirical results, based on data from 20 projects that delivered software for …
Parameter Non-Stationarity In A Model To Estimate The Business Value Of Information Technology, Robert J. Kauffman
Parameter Non-Stationarity In A Model To Estimate The Business Value Of Information Technology, Robert J. Kauffman
Research Collection School Of Computing and Information Systems
Developing robust and refined measures to quantify strategic impacts is a major challenge facing researchers who seek to improve methods for IT investment evaluation. This paper presents a means to test for parameter "non-stationarity" in a model which quantifies the strategic contribution of IT. An iterative "jackknife" procedure is used to diagnose if different local competitive and demographic conditions present in branch banking enhance or suppress leverage on deposit market share associated with membership in an ATM network. Preliminary results suggest this approach will be useful for managers who need to evaluate similar ITs which operate in different environments.
