Analyzing The Impact Of Cloud Services Brokers On Cloud Computing Markets, Richard D. Shang, Jianhui Huang, Yinping Yang, Robert J. Kauffman
Research Collection School Of Computing and Information Systems
This research offers a theoretical model of brokered services and provides an analysis of their impact on the cloud computing market with risk preference-based stratification of client segments. The model structures the decision problem that clients face when they choose among spot, reserved and brokered services. Although all the three types of services do not indemnify the cloud services client against other kinds of service outages, due to changes in market demand, service interruptions occur most frequently in the spot market, and are lower when brokered services are offered, and no risk of inter-ruption is involved in reserved services. Based …

Coordinating A Supply Chain With A Manufacturer-Owned Online Channel: A Dual Channel Model Under Price Competition, Jennifer K. Ryan, Daewon Sun, Xuying Zhao
Department of Supply Chain Management and Analytics: Faculty Publications
We consider a dual channel supply chain in which a manufacturer sells a single product to end-users through both a traditional retail channel and a manufacturer-owned direct online channel. We adopt a commonly used linear demand substitution model in which the mean demand in each channel is a function of the prices in each channel.We model each channel as a news vendor problem, with price and order quantity as decision variables. In addition, the manufacturer must choose the wholesale price to charge to the independent retailer. We analyze the optimal decisions for each channel and prove the existence of a …

Service-Oriented Methodology For Systems Development, Mark Keith, Haluk Demirkan, Michael Goul
Faculty Publications
Despite advances in software development practices, organizations struggle to implement methodologies that match the risk in a project environment with needed coordination capabilities. Plan-driven and agile software development methodologies each have strengths and risks. However, most project environments cannot be classified as entirely “risky” or “stable,” suggesting the need for hybrid approaches. We leverage a design science approach to implement a novel hybrid methodology based on concepts from the service-oriented paradigm. We motivate the approach using theory on interdependence and coordination, and design the methodology using theory on modularity and service-dominant logic. We also examine the effects of its adoption …

Conducting research that will make an impact is a difficult challenge for any research discipline. Information Systems is no exception, and there is much discussion on how to increase the level of real-world impact of our research. This paper details a framework for generating high-impact research through a DSR-driven program of research. The framework rests on the propositions that as opposed to individual or ad-hoc team-driven approaches, increased impact is more likely to be realized by 1) sustained collaborative research programs that 2) employ multiple research methods to 3) shepherd concepts from the ideation stage all the way to realized, …

Distributed Development And Product Line Decisions, Ram Bala, V. Krishnan, Wenge Zhu
Information Systems and Analytics
Distributed product development is becoming increasingly prevalent in a number of industries. We study how the global distribution of product development impacts the profit-maximizing product line that a firm offers. Specifically, we formulate a model to understand the linkage between cost arbitrage as a driver of distributed development and consequent market implications such as customer perceived quality loss to remotely developed products. Analysis of the model reveals that a firm should expand the product line for a development-intensive good only at intermediate values of cost advantage and quality loss. We modify the base model to include development capacity constraints as …

Synergy And Its Limits In Managing Information Technology Professionals, Thomas W. Ferratt, Jayesh Prasad, Harvey Enns
MIS/OM/DS Faculty Publications
We examine the effects of human resource management (HRM) practices (e.g., career development, social support, compensation, and security) on IT professionals‟ job search behavior. Job search is a relatively novel dependent variable in studies of voluntary withdrawal behavior, in general, and for IT professionals, in particular. From a universalistic perspective, HRM practices individually and in combination exhibit independently additive effects on job search behavior. Our study contrasts this perspective with configurational theory, hypothesizing that proposed idealtype configurations of HRM practices have synergistic effects on job search behavior. We contribute to the IT and broader HRM literature by theoretically explicating and …

Co-Space refers to interactive virtual environment modelled after the real world in terms of look-and-feel, functionalities and services. We have developed a 3D virtual world named Nan yang Technological University (NTU) Co-Space populated with virtual human characters. Three key requirements of realistic virtual humans in the virtual world have been identified, namely (1) autonomy: Agents can function on their own, (2) interactivity: Agents can interact naturally with players, and (3) personality: Agents can exhibit human traits and characteristics. Working towards these challenges, we propose a brain-inspired agent architecture that integrates goal-directed autonomy, natural language interaction and human-like personality. We conducted …

Equilibrium Financing In A Distribution Channel With Capital Constraint, Bing Jing, Xiangfeng Chen, Gangshu (George) Cai
Information Systems and Analytics
There exist capital constraints in many distribution channels. We examine a channel consisting of one manufacturer and one retailer, where the retailer is capital constrained. The retailer may fund its business by borrowing credit either from a competitive bank market or from the manufacturer, provided the latter is willing to lend. When only one credit type (either bank or trade credit) is viable, we show that trade credit financing generally charges a higher wholesale price and thus becomes less attractive than bank credit financing for the retailer. When both bank and trade credits are viable, the unique equilibrium is trade …

Entrepreneurship has been the fundamental topics of discussion among the politicians, economists, and academics. Business creation is especially critical in developing countries to stimulate economic growth. The present study attempts to examine entrepreneurial inclination among students who are a potential source of entrepreneurs. The findings of the present research study indicate that majority of our business students are not entrepreneurial-inclined. They do not seem to possess strong entrepreneurial characteristics and entrepreneurial skills, and they are not keen in starting a new business. The roles of higher institutes of education and the government in promoting entrepreneurship are discussed.

Although the interactions between information technology and the context of government-to-business relations challenge the implementation of information systems, the challenges are currently under-researched. Therefore, this paper analyzes the mutual shaping between technology integration and the context. Based on an empirical study of the deployment of electronic cash registers for value-added tax administration, the analysis explains how government-business dialectics inform the design of relations between institutional, technological and organizational factors. The explanations lead to the argument for a dialectical design perspective on implementation that facilitates a systematic comprehension of (1) the inducements of design; (2) the relationships between the factors as …
