The IT architecture for meter reading and utility services is at the core of new business models and has a decisive role as an enabler for resource efficiency measures. The communication architecture used by those services has significant impact on cost, flexibility and speed of new service rollout. This article describes how the dominant system model for meter reading came about, what alternative models exist, and what trade-offs those models have for rollout of new services by different stakeholders. Control of a self learning home automation system by dynamic tariff information (Real-Time-Pricing) is given as an application example.
This paper shows the experiences made with a multimedia based case study in academic education. The case study has been used within three courses of business process engineering. It was compared to a case study based solely on text. 13 assumptions have been evaluated. The main conclusion is that the multimedia based case study is much more practice oriented than a text based case study. Also the solutions of the students, which did the multimedia based case study, have been of higher quality. But on the other hand the expectations of the students to a multimedia based system are hard to meet. Based on these experiences some hints in further developing of multimedia based case studies are formulated.
