    Designing cross-organizational e-business applications faces the problem that the collaborating businesses must align their commercial interests without any central decision making authority. The design process must therefore yield a clear view of the commercial value of the collaboration for each economic actor, as well as a clear specification of the activities to be performed by each actor and a specification of information systems to be used by each actor. We present guidelines for designing the value network of the collaboration, which shows the commercial value of the collaboration for each participating actor. We then present guidelines for transforming the value network into process models, which show the feasibility of implementing the value network in the business processes of the actors. Our approach has been developed in different consultancy projects. We illustrate our approach with a consultancy project performed at a company that we will call the Amsterdam Times

    Introduction: In telemedicine, technology is used to deliver services. Because of this, it is expected that various actors other than those involved in traditional care are involved in and need to cooperate, to deliver these services. The aim of this study was to establish a clear understanding of these actors and their roles and interrelationships in the delivery of telemedicine. A video teleconsultation service is used as a study case. Methods: A business modeling approach as described in the Freeband Business Blueprint Method was used. The method brings together the four domains that make up a business model, that is, service, technology, organization, and finance, and covers the integration of these domains. The method uses several multidisciplinary workshops, addressing each of the four domains. Results: Results of the four domains addressed showed that (1) the video teleconsultation service is a store and put-forward video teleconsult for healthcare providers. The service is accepted and has added value for the quality of care. However, the market is small; (2) the technology consists of a secured Internet Web-based application, standard personal computer, broadband Internet connection, and a digital camera; (3) a new role and probably entity, responsible for delivering the integrated service to the healthcare professionals, was identified; and finally (4) financial reimbursement for the service delivery is expected to be most successful when set up through healthcare insurance companies. Pricing needs to account for the fee of healthcare professionals as well as for technical aspects, education, and future innovation. Discussion: Implementation of the video teleconsult service requires multidisciplinary cooperation and integration. Challenging aspects are the small market size and the slow implementation speed, among others. This supports the argument that accumulation of several telemedicine applications is necessary to make it financially feasible for at least some of the actors

    As time moves on, a trend crystallizes that sets new requirements on content management systems. The circle of users shifts from a small technically experienced group to a large network of inexperienced editors. Literature stresses that a higher need for usability is present if personnel with a low grade of human computer interaction expertise is using a system. But how can system designers accomplish a high level of usability? This study suggests a preview as an important factor for strengthening the usability (effectiveness, efficiency and satisfaction) of a content management system. The findings of this study support the hypothesis: the results showed that a preview enhances the userspsila satisfaction with the system. Moreover, the study shows that the userspsila confidence to be able to work with the system is an important factor; the results showed positive correlations between confidence and satisfaction and between confidence and effectiveness
