- ZeitschriftenartikelIs it Worth the Effort?(Business & Information Systems Engineering: Vol. 59, No. 2, 2017) Meier, Christian; Kundisch, Dennis; Willeke, JochenThe adequate consideration of resource interactions among IS projects is a challenging but important requirement within IS project portfolio selection. However, the literature does not mention any potential techniques for the identification and assessment of resource interactions. Moreover, the literature has so far neglected the question of the trade-off between time and effort invested in identifying and evaluating resource interactions caused by resource sharing among projects, compared to the benefits derived from this procedure. Hence, the paper’s contribution is twofold. First, a technique to support the identification and evaluation of potentially economically relevant resource interactions is suggested. Second, the paper proposes a decision model that allows to calculate a theoretical upper bound for the amount of effort that should be invested in improving estimates for identified interactions as part of the portfolio planning process.

- ZeitschriftenartikelRetained Organizations in IT Outsourcing(Business & Information Systems Engineering: Vol. 59, No. 2, 2017) Goldberg, Marius; Kieninger, Axel; Satzger, Gerhard; Fromm, HansjörgIT outsourcing is a strategic option which enables companies to focus on their core competencies. Over time however, many outsourcing arrangements suffer from severe problems. While the design of retained organizations is generally seen as a critical element, there is hardly any empirical evidence on how the choice of the organizational setup is linked to the occurrence of outsourcing management problems later on. In this work, a quantitative study across various outsourcing arrangements is used to identify the key outsourcing management problems and their interdependency with organizational attributes of retained organizations. It is shown that the key problems differ by outsourcing degree, and critical organizational attributes for each of these problems are unveiled. The paper’s objective is to enhance the design of retained organizations to enable more mature and successful outsourcing solutions as well as to provide foundations for future IS research.
- ZeitschriftenartikelService-Channel Fit Conceptualization and Instrument Development(Business & Information Systems Engineering: Vol. 59, No. 2, 2017) Hoehle, Hartmut; Kude, Thomas; Huff, Sid; Popp, KarlElectronically mediated self-service technologies in the banking industry have impacted the way banks service consumers. Despite a large body of research on electronic banking channels, no study has been undertaken to empirically explore the fit between electronic banking channels and banking services. To address this gap, we developed and validated a service-channel fit conceptualization and an associated survey instrument. We applied a mixed methods approach and initially investigated industry experts’ perceptions regarding the concept of ‘service-channel fit’ (SCF). The findings demonstrated that the concept was highly valued by bank managers. Next, we developed an instrument to measure the perceived service-channel fit of electronic banking channels. The instrument was developed using expert rounds and two pretests involving approximately 300 consumers in New Zealand. Drawing on IS alignment literature, we created a parallel instrument allowing us to calculate SCF across three unique fit dimensions, including service complexity-channel fit, service importance-channel fit, and service routineness-channel fit. To explore the nomological validity of the SCF construct, we linked SCF to customers’ intention to use a specific channel for a particular banking task. We tested our model with data from 340 consumers in New Zealand using Internet banking applications for two different banking tasks. The results of our study have theoretical and practical implications for how clients should be serviced through electronically mediated banking channels.
