Digitalization has redefined many aspects of our daily lives and continues to do so. Increasingly, it is also redefining how we perceive and experience mobility and transportation. With this paper, we wish to offer a way of capitalizing on this transformation. It is our shared opinion that, as of today, we will need to build a cooperative new digital mobility infrastructure beyond company borders and across established industries. We thus extend an invitation to contributors from around the globe - companies, scientific and governmental institutions, and commuters - to join us and shape this digital mobility infrastructure together.

Electricity market design varies across countries throughout Europe. Thereby the provision and remuneration of flexibility always takes place in short-term market segments. Taking into consideration the fundamental changes of the power system, this paper discusses options for the future short-term market design. We develop a conceptual basis for a possible integration of currently separated short-term market segments. Market segment integration (MSI) is defined as the interaction between and possible combination of market segments, i.e. intraday market (ID), congestion management (CM) and balancing market (BA). The paper especially focusses on two options, namely an integrated BA and CM market and an integrated ID and CM market. For these options we determine the basic design features. We propose a criteria catalogue which allows the evaluation of the market design options. Based on several criteria we discuss possible positive and negative consequences as well as potential solutions. [less ▲]

Blockchain is considered to be enabling technology that is going beyond the Bitcoin crypto currency. It replaces centralized transaction management by the distribution of transactions across a network of nodes with different methods for consensus finding. This major change of governance may change sectors of our societies far beyond digital currencies. Fraunhofer FIT established a Blockchain Lab in 2016 in order to explore its impact. It will serve as an experience lab for technical components, implementation platforms, application prototypes and blueprints for novel governance, process, and business models. [less ▲]

These days, due to the high level of interactions between individual projects, IT project portfolios are best described as IT project networks. While varied and frequent interactions between single IT projects create additional risks, they also generate the possibility of additional synergistic effects. This, however, is not reflected in current methods for IT project portfolio evaluation and project portfolio selection, which neither account for specific network characteristics nor do they clearly distinguish between the types of interaction and their effects. In this paper, we model resource synergies and dependencies within IT project networks by means of weighted, undirected and directed graphs and describe how alpha centrality allows for an assessment of both. We further illustrate the importance of accounting for network characteristics and the equal importance of distinguishing between resource synergies and resource dependencies. Our model can therefore be applied to gain practical insights on IT project portfolios [less ▲]
