3 - Product and Service Modularity Strategies Game for Mass Customization

Anu Bask, Assistant Professor, Aalto University School of Business, P.O. Box 21220, Helsinki, 00076 Aalt, Finland, anu.bask@aalto.fi, Juliana Hsuan, Mervi Rajahonka, Markku Tinnilä Modularity has been recognized as a powerful concept for improving the efficiency and management of product design and manufacturing. However, the integrated view on product and service modularity approaches is under researched. We propose four strategies to match combinations of products and services through modularization strategies for mass customization. 4 - The Impact of Product and Service Modularity on Business Performance – A Survey of Danish Manufacturers Thomas Frandsen, Copenhagen Business School, Dept. of Operations Management, Solbjerg Plads 3, Frederiksberg, DK- 2000, Denmark, tfr.om@cbs.dk, Juliana Hsuan, Jawwad Z. Raja Manufacturers are increasingly turning towards services and integrated solutions as a way of strengthening their competitiveness, a transition receiving growing attention in the literature. However, the relation between product and service architecture and its impact on service strategy and the performance of manufacturers is not well understood. Based on a survey of Danish manufacturers we explore the relationship between product and service modularity and their effects on business performance.

Box 210108, Tucson, AZ, 85721, United States of America, weichen@email.arizona.edu, Kevin Zhu, Terrence August Open-source software (OSS) firms are increasingly using service-based business models to compete with established proprietary software firms. We study a 3-way game with strategic contribution from the community and focus on how open- source licensing affects competition among an open-source originator, open-source contributor, and a proprietor competing in the same software market. 2 - An Empirical Study of Market Switching Behavior of Mobile App Developers Hossein Ghasemkhani, Assistant Professor, Purdue University, 425 W. State Street, West Lafayette, IN, 47907, United States of America, hossein@purdue.edu, Young-Jin Lee, Karen Xie, Yong Tan Mobile app developers switch the positioning of their apps between free and paid submarkets. They offer their previously paid apps for free to create positive network effects, and set prices on previously free apps to reap the benefits. We empirically study the developers’ decision to determine the instantaneous market of their apps, and examine how it affects performance. We find that prior performance and duration in either market are significantly related to the developer’s decision. 3 - How Does Communication Improve Conversion Rate on E-commerce: A Bayesian Approach Haoyan Sun, PhD Candidate, University of Washington, Mackenzie 328, Seattle, WA, 98115, United States of America, haoyan@uw.edu, Ming Fan We examine communication of buyers and sellers on the E-commerce platform through Instant Message (IM) to understand the ways of improving conversion rate. By casting this problem in a hierarchical bayesian framework, we are able to address the endogeneity problem where IM communication is endogenous in determining the conversion rate. Using data collected from TaoBao, China’s leading C2C online marketplace, we show that communication can significantly drive the conversion rate.

Chair: Stanko Dimitrov, Assistant Professor, University of Waterloo, 200 University Avenue West, Waterloo, Canada, sdimitro@uwaterloo.ca 1 - On the Robust Design of Access Networks Integrating Optical Fiber and Wireless Technologies Fabio D’Andreagiovanni, Senior Researcher, Konrad-Zuse- Zentrum för Informationstechnik, Takustr. 7, Berlin, Germany, d.andreagiovanni@zib.de, Jonad Pulaj, Axel Werner An important recent trend in telecommunication access networks is the integration of optical fiber and wireless technologies (Fi-Wi). The design of Fi-Wi networks can be formulated as variants of Connected Facility Location Problems, including fiber connectivity and wireless coverage constraints. We consider here an uncertain version of the Fi-Wi design problem, tackling signal propagation uncertainty. We introduce a new model for it and present computational results on realistic instances. 2 - Two Terminal Reliability in a Mobile Ad-hoc Network Timothy Matis, Professor, Texas Tech University, 2500 Broadway, Texas, United States of America, Timothy.Matis@ttu.edu, Binchao Chen, Aaron Phillips The spatial distribution of nodes in a random waypoint model of a Mobile Ad-hoc communications networks exhibits central tendency. In this presentation, we will discuss analytical expressions for one and two hop connectivity as a function of node location. 3 - Impact of Security Concerns on Online Shopping by Device Stanko Dimitrov, Assistant Professor, University of Waterloo, 200 University Avenue West, Waterloo, Canada, sdimitro@uwaterloo.ca, Brian Cozzarin As various devices are used to access online stores, it is unclear if consumers’ security concerns impact shopping decisions equivalently regardless of access device. In this study we characterize the impact of security concerns across device types and show that consumers with security concerns are far less likely to make purchases using a mobile device than a personal computer. Similarly, we show that individuals without security concerns are the major drivers behind mobile commerce. SC09 09-Room 309, Marriott Managing Innovation: Products, Services, Employee Attributes and Organizational Performance Sponsor: Technology, Innovation Management & Entrepreneurship Sponsored Session Chair: Juliana Hsuan, Professor, Copenhagen Business School, Dept. of Operations Management, Solbjerg Plads 3, Frederiksberg, DK-2000, Denmark, jh.om@cbs.dk 1 - The Relationship Between Individual Employee Attributes and Radical Innovation Lee Davis, Associate Professor, Copenhagen Business School, Department of Innov and Org Econ, Kilevej 14A, Frederiksberg, 2000, Denmark, ld.ino@cbs.dk, Karin Hoisl, Jerome Davis We investigate the impact of individual employee attributes like experience, ability or motivation on radical innovation and whether the organizational context moderates this relationship. We find that the importance of individual attributes varies with organizational context. 2 - The Impact of Organizational Routines in Cumulative Innovation Leonardo Santiago, Associate Professor, Copenhagen Business School, Department of Operations Management, Solbjerg Plads 3, Blok B 5. sal, Frederiksberg, 2000, Denmark, ls.om@cbs.dk, Julia Couto The capacity to continuously innovate is crucial for organizations to achieve or maintain their competitive advantage. A sequence of innovations can provide to a company not just a new product or technique but also a platform of knowledge that will support their future innovations. This work investigates the way knowledge is accumulated by a company over time, associating managerial decisions to the dynamics of innovation.
