Abstract: Ubiquitous and pervasive computing is fundamentally transforming product categories such as music, movies, and books and the associated practices of product searching, ordering, and buying. This paper contributes to theory and practice of digital payments by conducting a design science inquiry into the mobile phone wallet (m-wallet). Four different user groups, including young teenagers, young adults, mothers and businessmen, have been involved in the process of identifying, developing and evaluating functional and design properties of m-wallets. Interviews and formative usability evaluations provided data for the construction of a conceptual model in the form of sketches followed by a functional model in the form of low-fidelity mockups. During the design phases, knowledge was gained on what properties the users would like the m-wallet to embody. The identified properties have been clustered as ‘Functional properties’ and ‘Design properties’, which are theoretical contributions to the on-going research on m-wallets. One of the findings from our design science inquiry into m-wallets is that everyday life contexts require that evaluation criteria have to be expanded beyond “functionality, completeness, consistency, accuracy, performance, reliability, usability, fit with the organization, and other relevant quality attributes” [12] that are used within current design science work.

Abstract: This paper reports the findings of a research project investigating the utilization and continuous improvement of Enterprise Resource Planning (ERP) systems. Adopting the aspects of a resource management framework and Critical Success Factor research, an initial framework is developed. The framework is developed through a survey of ERP system expert consultants. A number of factors and causalities are identified, including the positive role of use by top management and the role of corporate culture. Two factors were found to have a negative impact on utilization. The first is the unreflective use of ERP system implementation methods, which can ‘kill’ the visions and ideas of implementing ERP systems, while the second is the vanilla implementation strategy.

Abstract: The purpose of this paper is to contribute to the design of e-wallets. e-wallets are intended to replace the existing physical wallet, with its notes, coins, photos, plastic cards, loyalty cards etc. Four different user groups, including teenagers, young adults, mothers and businessmen, has been involved in process of identifying, developing and evaluating functional and design properties of e-wallets. Interviews and formative usability evaluations have provided data for the construction of first a conceptual model in the form of sketches, and later a functional model in the form of low-fidelity mockups. During the design phases, knowledge was gained on what properties the test users would like the mobile wallet to hold and the properties implemented in four prototypes. The identified properties have been clustered as ‘Functionality properties’ and ‘Design properties’, which are theoretical contributions to the ongoing research in mobile wallets.

Abstract: This paper analyzes the 44 papers included in the proceedings of the 5th ICMB conference in Copenhagen 2006. The purpose of the paper was to investigate to what extent the conference fulfilled its objectives which was to compare previous expectations with present realities along the following four areas: (1) business models, (2) the influence of m-business on private and work life, (3) the impact of regulation, and (4) the re-composition of the value network. In the analysis we apply the well-known framework by Lyytinen and Yoo for studying nomadic computing. In addition to this we also classify the papers in relation to type of artifact investigated, application area, and research methodology. The analysis show that the main focus lay on the use and adoption of mobile services – over 60% of the papers address. Few papers address the impact of service on any level of analysis. Business model is a recurring topic in 17 of the papers. There is lack in theorizing of the artifact, e.g. many just study mobile devices, but do not describe what type they study.

Abstract: To become sustainable, or green, is in Nordea not a process that is forced upon the organization by top management. On the contrary, it is a smooth and soft process lead by champions and supported by the management team. One could compare the process with the game curling, where a small grain of sand might stop the curling stone to reach the nest. In the greening process of Nordea it is a risk that the process might be set back for several years if it is not carefully managed. To ensure that no grain of sand hinders the process, a slow and incremental strategy is in place. The process is supported and encouraged by the management and grounded in the corporate values....

Abstract: Historically, organizations developed their information systems in-house. Today, a large portion of information systems development is based on acquisition of pre-made information systems, so called commercially off the shelf (COTS) systems. This approach of developing information systems requires new skills and methods supporting the process of evaluating and selecting information systems. This paper presents a method for selecting COTS systems. The method includes the following phases: problem framing, requirements and appraisal, and selection of systems. The idea and distinguishing feature behind the method is that improved understanding of organizational’ ends’ or goals should govern the selection of a COTS system. This can also be expressed as a match or fit between ‘ends’ (e.g. improved organizational effectiveness) and ‘means’ (e.g. implementing COTS systems). This way of approaching the selection of COTS systems as viewing COTS systems as a ‘mean’ to reach organizational ‘ends’ is different from the mainstream view of information systems development, which view information systems development as a problem solving process, and the underlying ontological view in other COTS selection methods, which focus on selection of functionality not reaching organizational ends.

Abstract: This paper derives a theoretical framework for consideration of both the technologically driven dimensions of mobile payment solutions, and the associated value proposition for customers. Banks promote traditional payment instruments whose value proposition is the management of risk for both consumers and merchants. These instruments are centralised, costly and lack decision support functionality. The ubiquity of the mobile phone has provided a decentralised platform for managing payment processes in a new way, but the value proposition for customers has yet to be elaborated clearly. This inertia has stalled the design of sustainable revenue models for a mobile payments ecosystem. Merchants and consumers in the meantime are being seduced by the convenience of online and mobile payment solutions. Adopting the purchase and payment process as the unit of analysis, the current mobile payment landscape is reviewed with respect to the creation and consumption of customer value. From this analysis, a framework is derived juxtaposing customer value, related to what is being paid for, with payment integration, related to how payments are being made. The framework provides a theoretical and practical basis for considering the contribution of mobile technologies to the payments industry. URI: http://hdl.handle.net/10398/8348 Files in this item: 1
