Motivated by challenges facing IT procurement, this paper studies a hybrid procurement model in which a reverse auction of a fixed-price IT outsourcing contract may be followed by renegotiation to extend the contract’s scope. In this model, the buyer balances the needs to incentivize noncontractible vendor investment and to curb the winning vendor’s information rent by choosing the initial project scope and the buyer’s investment in the quality of the project. We find that a buyer may benefit from inducing ex post renegotiation to motivate vendor investment, especially when the winning vendor has high bargaining power and the quality uncertainty is low. Broadening the initial scope reduces information rent but leaves little room for ex post renegotiation and, hence, discourages vendor investment, whereas increasing the buyer’s investment has opposite effects. Interestingly, the two measures can be strategic substitutes or complements depending on the likelihood of the renegotiation and the two parties’ bargaining powers. The buyer may strategically set a low initial project scope and high investment to incentivize renegotiation and vendor investment, which may explain why many IT outsourcing projects start small and allow expansions. Our findings also generate several testable predictions for IT outsourcing. This paper was accepted by Kartik Hosanagar, information systems.

In this paper, we perform a literature review on the current state of knowledge about homeowners in the context of the adoption of renewable heating systems. Despite a considerable number of studies about homeowners, homeowner–installer interactions, and ways to improve the effectiveness of renewable heating programs, based on homeowner knowledge, have not yet been studied in much detail. To address these knowledge gaps, we conduct a qualitative study on single-family house owners who installed heat pumps and took part in a renewable heating program in Geneva, Switzerland. We cover homeowner practices in choosing installers and heating system types, homeowners’ feedback about heat pump installation and use, as well as their experience in participation in the renewable heating program. Based on the literature review and the findings from the interviews, we provide the following recommendations on how to increase the effectiveness of renewable heating programs: (a) support for homeowners should not be limited to financial incentives; (b) partnership programs with installers could help to increase the quality of installation services and enable homeowners to choose qualified installers; and (c) assisting homeowners in pre-qualification and ex-post analysis, in learning how to operate their renewable heating systems and in solving problems during the post-installation period, can contribute to improved technology reputation, which can, in turn, increase technology uptake by other homeowners.

Small pieces of metal are generated during trimming of automotive body panels. Commonly referred to as slivers, these pieces can be imprinted into the surface of stamped panels. This may require metalfinish of every stamped exterior panel. The objective of the paper is to study the influence of trimming conditions on quality of trimmed surface and to modify the trimming process to eliminate slivers and burrs from the trimmed surface. Suggested solution includes two measures: 1) building an elastic support of the offal eliminating bending of the area of the blank being trimmed off; 2) creating the preference of crack propagation from the lower shearing edge by machining a small radius on the upper shearing edge.

When confronted with a new product, consumers often find it difficult to predict how it will perform, and such uncertainty reduces consumers’ willingness to adopt the product. In this paper, we consider a market whereby consumers decide when and which product to buy, given that they know the product quality of the incumbent but are uncertain about that of the entrant. We investigate how consumer uncertainty about product quality affects firms’ behavior-based pricing and customer acquisition and retention dynamics. Using a two-period vertical model, we find that, under high-end encroachment, an increase in consumer uncertainty reduces the entrant’s profit and hurts the incumbent’s profit when the quality differential between the products is relatively small, whereas, under low-end encroachment, increasing uncertainty not only benefits the incumbent but also can favor the entrant. An important implication for entrants is that the marketing activities, which aim to reduce consumer uncertainty about product functionalities, may fail to improve profitability. We also find that the entrant lowers the price for uninformed customers and raises the price for repeat buyers under high-end encroachment but lowers the price for all customers under low-end encroachment. We further examine the subsidy strategy and show that, when the entrant’s product has a significant quality advantage and consumer uncertainty is high but not very high, the optimal strategy for the entrant is to acquire all consumers who do not buy from the incumbent by providing subsidies and to drop the low-valuation customers by means of a high price after their uncertainty is resolved.

Validity and reliability of research and its results are important elements to provide evidence of the quality of research in the organizational field. However, validity is better evidenced in quantitative studies than in qualitative research studies. As there is diversity within qualitative research methods and techniques, there is no universally accepted criteria to assess validity in qualitative studies; its usefulness is also questioned. Therefore, in this paper, we argue that qualitative research should adopt a processual view approach of validity since it should not be the product of a single test or just one step in the research. Processual validity both supports good research and helps in its reflection and guidance. To illustrate our approach, we present the processual approach adopted by one of the coauthors during the development of a research project. We highlight the validity assurance activities for both ex ante and ex post research, peer review and participation in an international conference, which corroborated the quality of the processual approach and the results that were obtained.

The emphasis of human-computer interaction (HCI) design on the technology and computer action tends to obscure consideration of the contribution of the computer interface to the service interaction. This chapter suggests that since a majority of commercial information systems support or provide services, the nature and progression of the service encounter should be a key concern of human computer interface designers. The chapter proposes the concept of service-oriented HCI in which HCI design is derived from service design, dialog is driven by customer needs and perceptions, activities that have led up to the service encounter are considered, and the service interaction dialog is aligned with the computer dialog. As part of service-oriented HCI, the chapter illustrates the use of scripting to examine ex-post the role of a computer interaction in a service encounter. It demonstrates that the computer dialog can drive the service interaction in such a way that the quality of the interaction is reduced and customer satisfaction affected. It concludes that the role of the computer system in a service interaction is an area for further research. Furthermore, script analysis may enable the development of human-computer dialogs that meet some of the criteria of service-oriented HCI.

Many companies recently have been choosing information technology (IT) outsourcing in response to complicated information systems and various internal requirements. In order to monitor and maintain a high quality of IT outsourcing vendors’ services, it is necessary to develop a system to evaluate IT outsourcing customer satisfaction. The system can be used as a tool for choosing IT outsourcing providers. Through the literature reviews and expert interviews, we propose the evaluation system of the IT outsourcing customer satisfaction. Using AHP (analytic hierarchy process) technique, attributes associated with customer satisfaction in IT outsourcing environments are then rated in terms of their importance. The customer satisfaction evaluation system is applied to IT outsourcing service receivers in Korea to demonstrate its practical implications.
