P2P promised a revolution in business computing which has not arrived. It has become synonymous with illegal file sharing and copyright violations. Meanwhile the information systems industry has undergone a paradigm change, and we are supposedly living in a world of cloud computing and mobile devices. It is pertinent to examine if P2P, as a revolutionary technology, is still relevant and important today and will be in future. One has to examine this question in the context of the fact that P2P technologies have matured but have however had limited adoption outside file sharing in the consumer space. This paper provides a detailed analysis of P2P computing and offers some propositions to answer the question of the relevancy of P2P. It is proposed that P2P is still a relevant technology but may be reshaped in the coming years in a different form as compared to what exists today.展开更多

Our study contributes to the literature because it has investigated an ISO 31000 workflow process approach to group decision making for reducing backorders in the supply chain, from an integrated perspective utilizing Pareto charts and Petri nets. The contribution to the literature is also enhanced by the L-Project illustrative example that presents an evaluation hierarchy of supply chain risk. The proposed method is appropriate for use in situations in which assessment information may be qualitative or precise quantitative information is either unavailable or too costly to compute.展开更多

This paper examines the domain of maintenance, repair, and overhaul (MRO) of the Sikorsky UH-60 helicopter involving multiple enterprises, and represents it through an ontology using the OWL Language and Protégé tool. The resulting ontology gives a formal and unambiguous model/representation of the MRO domain that can be used by multiple parties to arrive at a common shared conceptualization of the MRO domain. The ontology is designed to be conformant to ISO 13030 or the Product Life Cycle Support Standard (PLCS) standard, hence representing the state of being as per this standard especially at the interfaces between enterprises while incorporating existing reality to the greatest possible extent within the enterprises. As a result the ontology can be used to design Information Systems (IS) and their interfaces in all enterprises engaged in MRO to alleviate some of the issues present in the MRO area and to support business intelligence efforts.展开更多

However, with the rise of information technology (IT) and globalization of businesses, information has taken a far more important role in explaining business performance. IT can be used to enhance research activities of the firm;and its product knowledge can be used to improve business productivity. In fact, scholars and researchers have indicated that knowledge can be a source of sustainable advantages for the firm. However, not much research has been done that explains what kind of knowledge is important for sustainable advantages. In this paper, we present three kinds of knowledge: core, complementary, and peripheral. We also develop an idea of shared space along three dimensions: physically shared space, technically shared space, and cognitively shared space. The main theme of this paper is to show the relevance and importance of these different kinds of knowledge along the shared spaces that create sustainable advantages for the firm.展开更多

The study follows up on the work on the definition of the construct of IS agility which is defined as the ability of IS to sense a change in real time;diagnose it in real time;and select and execute an action in real time. It explores the attributes for sensing in an Agile Information System. A set of attributes was initially derived using the practitioner literature and then refined using interviews with practitioners. Their importance and validity were established using a survey of the industry. All attributes derived from this study were deemed pertinent for sensing in an agile information system. Dimensions underlying these attributes were identified using Exploratory Factor Analysis. This list of attributes can form the basis for assessing and establishing sensing mechanisms to increase IS agility.展开更多

Software productivity was measured in function points per person hours, and software development time was measured in number of elapsed days. Using field data on over 130 field software projects from various industries, we empirically test the impact of team size, integrated computer aided software engineering (ICASE) tools, software development type, software development platform, and programming language type on the software development productivity and development time. Our results indicate that team size, software development type, software development platform, and programming language type significantly impact software development productivity. However, only team size significantly impacts software development time. Our results indicate that effective management of software development teams, and using different management strategies for different software development type environments may improve software development productivity.展开更多
