The conversion of a legacy system to a system based on a commercial-off-the-shelf (COTS) package demands a dedicated guidance. The assumption that it is just a matter of adopting a selected package may prove disastrous and even more expensive than building the system in house and from scratch. Building a software solution based on a COTS package not only has its risks, but it is also different from a custom development effort, and it needs to follow a rigorous methodology for a successful implementation. Therefore, it is necessary to define how to solve some of the challenges that this type of project presents, and how to balance customer requirements with the features offered by the COTS package. To successfully and efficiently convert a legacy system into a new system based on COTS package, we developed and present a methodology that utilizes a general process flow chart, simplified use cases, and a mapping to the COTS package functionality. We also present the findings of a case study on the applicability and effectiveness of the proposed methodology for the conversion of a legacy laboratory information management system (LIMS).

Mobile commerce had been expected to become a major force of e-commerce in the 21st century. However, the rhetoric has far exceeded the reality so far. While academics and practitioners have presented many views about the lack of rapid growth of mobile commerce, we submit that the anticipated mobile commerce take-off hinges on the emergence of a few killer apps. After reviewing the recent history of technologies that have dramatically changed our way of life and work, we propose a set of criteria for identifying and evaluating killer apps. From this vantage point, we argue that mobile payment and banking are the most likely candidates for the killer apps that could bring the expectation of a world of ubiquitous mobile commerce to fruition. Challenges and opportunities associated with this argument are discussed.

The knowledge of the positions of the different members in a group decision situation is used in a prototype of a group decision support tool that explicitly computes and presents the differences between the individual positions held by each group member to help the group describe and define the parameters of the decision problem. A collaboration model based on two stages, one of group structuring (communication), and one of individual discrimination (appropriation) is proposed. These stages alternate as each individual learns about other group members preferences, to accommodate other inputs and preferences, or to explore the problem. Information regarding the sources of disagreement between group members' positions and the changes that would be needed to achieve equal results are provided by the system, to help achieve a common solution (if possible).

Individual users are known to differ in their tendency to adopt new technologies. Among the individual differences, Personal Innovativeness in IT (PUT) has been shown to be a reliable predictor of users' beliefs about the ease of use and usefulness of new technologies. However, it is unclear what are the personality traits that make some users more innovative in IT than others. Personality traits are used in the psychology literature to explain human beliefs and behavior, and recently see a growing interest in the IS literature as an explanatory tool of user behavior. The present research investigates two personality traits established in the psychology literature, resistance to change (RTC) and Openness, as determinants of PUT A survey of 121 prospective users of a digital library system was conducted to test our hypotheses. The findings suggest that RTC and Openness are determinants of PUT Implications for research and practice are discussed.

Many peer-to-peer (P2P) networks have been widely used for file sharing. A peer acts both as a content provider and a consumer, and is granted autonomy to decide what content, with whom, and when to share. Is a P2P network an ideal vehicle for information sharing in collaborative learning? This study adopts the theory of planned behavior as a basis to study the sharing behaviors on a P2P network. Due to the lack of empirical data, we built a P2P network platform to conduct an experiment in a collaborative learning setting. Through the analysis we found the intention of sharing is only positively related with subjective norm. Based on this result, we assert that subjective norm, especially the discipline from the instructor, plays a critical role in motivating students to share knowledge on a P2P network for collaborative learning. From this empirical study, a hybrid architecture combining P2P networks with servers could be more favorable for collaborative learning.

This project uses empirical data to provide insights into the impact of open standards. This work moves beyond the existing literature by considering a large number of open standards, instead of handpicked case studies. The results of this research will be timely, as governments are advocating and sometimes mandating the use of open standards. We found inequalities in the impact of open standards that suggest a power law relationship, found that the duration of the development process does not affect the impact of a standard, and found the length of a standard (number of words), which reflects the technical complexity of a standard, affects the impact of a standard.

Interest in mobile computing applications has been increasing over the past few years. The Healthcare sector has recognized the potential for providing at "point-of-care" access to applications through mobile devices. The business value of the implementation of information technology (IT) has been studied from various perspectives. This paper explores the value of the implementation of mobile computing on the efficiency and effectiveness of an Emergency Medical Services organization in Australia. The research question that is addressed in this paper is: In what way do mobile systems deliver internal value in emergency healthcare organizations? The paper evaluates the responses by various stakeholders in an Australian Emergency Service organization. The paper makes the following three contributions. First, the case study indicates that the introduction of mobile systems can support ambulance services in providing more efficient and effective information that could potentially impact on their performance evaluation. Second. a number of advantages of the mobile system for emergency services are highlighted. Third, a delicate balance between internal data capture requirements versus external requirements of readability of the final electronic Patient Care Record is highlighted.

Interorganizational systems (IOS) adoption requires cooperation and collaboration between trading partners and, therefore, is reliant on the nature of their relationships. There has been some research that investigates relationships and how organizations progress from one level to the next level of adoption. However, these studies do not adequately justify the exclusion of other variables and are not theoretically based. This research extends the Kurnia and Johnston (2000) process model of IOS adoption by incorporating the notion of IOS adoption maturity and also modifies it from a supply chain to a dyadic level so better evaluations of progression can be performed. With this model, the dynamics of IOS adoption maturity can be better examined empirically.

This study analyzes tradeoffs online grocers face in their fulfillment strategy. Brick and click grocers initially favor fulfillment from stores rather than distribution centers. However, store fulfillment is vulnerable to congestion and "trolley rage" when pickers of online orders get in the way of traditional shoppers. Although fulfillment from distribution centers relieves store congestion, and improves picking productivity and product selection, online grocers show concern for the high cost and uncertain demand. We propose a model for minimizing congestion of online grocery orders. Practitioners can use the model to prevent customer dissatisfaction while researchers will find this study provides a basis for future model variants.

This effort investigated the use of wireless unattended sensor network motes in the surroundings of a freshwater lake. The network was required to organize, establish and maintain itself in or on the water. Commercial components developed by Crossbow Technologies were used in developing the experimental networks consisting of single and multiple nodes. Nodes were tested on a solid ground surface, on the surface of the water, below the surface of the water (but not submerged) and fully submerged. Performance metrics based on link quality, parent changes and formation time are presented under a variety of scenarios. It was observed that nodes operating on the surface of the water performed much better than those on a hard surface, operating at a greater inter-node spacing and experiencing fewer parent changes. Submerging one or both nodes had considerable but not overwhelming effects on network performance.
