Predictors of Formal Control Usage in IT Outsourcing Partnerships

Rustagi, S., King, W. R., Kirsch, L. J. — 2008-06-13

Client control over the vendor has been identified as a critical factor in successfully managing information technology outsourcing relationships. Though prior studies have suggested that "how much" control is exercised has significant ramifications for individuals and firms, relatively few studies have operationalized and studied this important concept. In this study, we define the amount of formal control as the variety of mechanisms used by a client to exercise control over a vendor and the extent to which the mechanisms are used. We use literature on transaction cost economics and organizational control to build a model of the antecedents of the amount of formal control. The study uses data from 138 client-vendor matched pairs working in eight large, long-term, ongoing outsourcing arrangements to test specific hypotheses. The results suggest that clients who have technical or relationship management knowledge, or have high levels of trust in their vendors, use formal control mechanisms to a lesser extent. On the other hand, task uncertainty was found to be positively associated with the amount of formal control, and the degree of core competency involved in the outsourced activity was not found to be related to the amount of formal control. These results are discussed, and implications for research and practice are drawn.

Capacity Provision Networks: Foundations of Markets for Sharable Resources in Distributed Computational Economies

Du, A. Y., Geng, X., Gopal, R., Ramesh, R., Whinston, A. B. — 2008-06-13

With the rapid growth of rich-media content over the Internet, content and service providers (SP) are increasingly facing the problem of managing their service resources cost-effectively while ensuring a high quality of service (QoS) delivery at the same time. In this research we conceptualize and model an Internet-based storage provisioning network for rich-media content delivery. This is modeled as a capacity provision network (CPN) where participants possess service infrastructures and leverage their topographies to effectively serve specific customer segments. A CPN is a network of SPs coordinated through an allocation hub. We first develop the notion of discounted QoS capabilities of storage resources. We then investigate the stability of the discount factors over time and the network topography using a test-bed on the Internet through a longitudinal empirical study. Finally, we develop a market maker mechanism for optimal multilateral allocation and surplus sharing in a network. The proposed CPN is closely tied to two fundamental properties of Internet service technology: positive network externality among cooperating SPs and the property of effective multiplication of capacity allocation among several distributed service sites. We show that there exist significant incentives for SPs to engage in cooperative allocation and surplus sharing. We further demonstrate that intermediation can enhance the allocation effectiveness and that the opportunity to allocation and surplus sharing can play an important role in infrastructure planning. In conclusion, this study demonstrates the practical business viability of a cooperative CPN market.

Addressing the What and How of Online Services: Positioning Supporting-Services Functionality and Service Quality for Business-to-Consumer Success

Cenfetelli, R. T., Benbasat, I., Al-Natour, S. — 2008-06-13

With the continued growth of business-to-consumer (B2C) e-business, online vendors are providing an increasing array of services that support and enhance their core products or services. For example, Amazon.com does not just sell books; it also enhances that core product with automated product recommendations, "wish list" tracking, order status updates, customer reviews, and many other valuable supporting services. These supporting services are made possible exclusively through the design and deployment of information technology (IT) to provide website supporting services functionality (SSF). In this paper, we define and develop the concept of B2C SSF and investigate how IT can support core products or services. We theorize the role that SSF plays in an environment where individuals who visit B2C websites are not only customers but also technology users. Given the unique online environment that amalgamates vendor services with information systems (IS), our model integrates theories from both services marketing and technology acceptance to help explain the behavior of these customers/users. In doing so, we investigate the role of the extensively researched concept of service quality in relation to SSF. Although service quality provides guidance for how supporting services should be provided (e.g., responsively and reliably), it does not address what those services are (e.g., product recommendations). SSF addresses this deficiency, thus providing both theoretical and practical benefits through a focus on IT design and deployment. The results of a field study support that SSF is an important predictor of customer beliefs and behavior, beyond that predicted by service quality alone. SSF is an important concept to consider—theoretically and practically—in IT-mediated B2C service.

Marketspace or Marketplace? Online Information Search and Channel Outcomes in Auto Retailing

Kuruzovich, J., Viswanathan, S., Agarwal, R., Gosain, S., Weitzman, S. — 2008-06-13

The growth of the Internet has spawned an increasing number of online information sources (OISs). The effect of OISs on consumer information search processes has been particularly striking in sectors such as auto retailing, where the typical consumer has conventionally been confronted with an unpleasant and inefficient purchase process. However, the relationships between the information found in the online "marketspace," consumer search in the offline "marketplace," and other aspects of the multichannel shopping process are not well understood. This study examines the differential impact of price and product information found in the marketspace, relating consumers' information needs and information retrieval from OISs to three shopping-related outcomes—purchase based on online infomediary referral (i.e., referred purchase), intensity of search in the marketplace, and online search satisfaction. We draw on a large data set of more than 16,000 new vehicle purchasers who reported using the Web for search related to their new vehicle purchase. We find that OISs offer different levels of price and product information and consumers are differentiated in their ability to retrieve this information. Further, the retrieval of price versus product information online has important implications for whether consumers consummate their online search through referred purchase or extend their search into the physical marketplace. Our results suggest different business models for infomediaries providing price and product information and underscore the need for designing information provisioning systems of OISs to facilitate transition between the marketspace and the marketplace.

Research Note--On Vendor Preferences for Contract Types in Offshore Software Projects: The Case of Fixed Price vs. Time and Materials Contracts

Gopal, A., Sivaramakrishnan, K. — 2008-06-13

Prior research has indicated that, on average, offshore vendors have higher profits associated with time and materials (T&M) contracts than fixed price (FP) contracts. This research raises two questions. First, Is the relative importance of various profit drivers different across two contractual regimes? Second, Does it follow that vendors unconditionally prefer T&M contracts for all projects? We address these questions by using data on 93 offshore projects completed by a leading Indian vendor. We use an endogenous switching regression framework and the program evaluation methodology to show that profit equations are distinctly different for the two contractual regimes. Using these two profit equations, we also identify contingencies under which the vendor prefers an FP contract to a T&M contract. We hypothesize that the vendor's ability leverage information asymmetry about capabilities and experiences translates into the vendor preferring FP contract to secure larger information rents. Our results support this hypothesis and suggest that the vendor would prefer the FP contract for larger and longer projects with larger teams. However, vendors would prefer a T&M contract when the risk of employee attrition from the project team is high. In addition, we discuss managerial implications of these results in the paper.

Research Note--Awareness Displays and Social Motivation for Coordinating Communication

Dabbish, L., Kraut, R. — 2008-06-13

Researchers and designers have been building awareness displays to improve the coordination of communication between distributed co-workers since the early 1990s. Awareness displays are technology designed to provide contextual information about the activities of group members. Most researchers have assumed that these displays improve the coordination of communication regardless of the relationship between the communicating parties. This article examines the conditions under which awareness displays improve coordination and the types of designs that most effectively support communication timing without overwhelming people with irrelevant information. Results from a pair of laboratory experiments indicate that awareness displays containing information about a remote collaborator's workload lead to communication attempts that are less disruptive, but only when the interrupter has incentives to be concerned about the collaborator's welfare. High-information awareness displays harmed interrupters' task performance, while abstract displays did not. We conclude that a display with an abstract representation of a collaborator's workload is optimal; it leads to better timing of interruptions without overwhelming the person viewing the display.
