Abstract:

An increasing number of large organizations are adopting agile and lean methods at larger scale for building complex software systems. One major critique of agile development and in particular of large-scale agile development is the neglect of proper architecting assistance in such development efforts. On the one hand, emergent architecture design may require excessive redesign efforts in large systems, while on the other hand, big upfront architecture delays the starting point of implementation. Domain-driven Design (DDD) addresses this problem by providing means for evolving the architecture of complex systems in an agile way. We describe how DDD can support large-scale agile development based on a conducted case study in a large insurance company with three agile teams. Furthermore, we present a framework for large-scale agile development that is largely based on Large-Scale Scrum and incorporates strategic and tactical DDD.

Abstract

The benefits of enterprise modeling (EM) and its contribution to organizational tasks are largely undisputed in business and information systems engineering. EM as a discipline has been around for several decades but is typically performed by a limited number of people in organizations with an affinity to modeling. What is captured in models is only a fragment of what ought to be captured. Thus, this research note argues that EM is far from its maximum potential. Many people develop some kind of model in their local practice without thinking about it consciously. Exploiting the potential of this “grass roots modeling” could lead to groundbreaking innovations. The aim is to investigate integration of the established practices of modeling with local practices of creating and using model-like artifacts of relevance for the overall organization. The paper develops a vision for extending the reach of EM, identifies research areas contributing to the vision and proposes elements of a future research agenda.

The team of Florian Matthes, consisting of Ingo Glaser, and Bernhard Waltl, has published their recent results on Named Entity Recognition, Extraction, and Linking in German Legal Documents at the 21st international legal informatics symposium (IRIS). The paper is going to be presented at the conference from 22-24 February 2018, Salzburg.

Software architecture is considered as a set of architectural design decisions. The recent trends, both in research and industry, call for improved tool support for software architects and developers to manage architectural design decisions and its associated concepts. As part of our ongoing work, we propose a framework for managing architectural design decisions in large software-intensive projects. Each component within this framework addresses specific use cases including (a) extraction and classification of design decisions from issue management systems, (b) annotation of architectural elements, (c) recommendation of alternative decision options, (d) reasoning about decisions’ rationale, and (e) recommendation of experts for addressing design decisions. These components are planned to be iteratively realized and evaluated using the design science research approach. We believe that the realization of such a framework will allow an architectural knowledge management systems to integrate with the design, development, and maintenance phases to support stakeholders not only to document design decisions but also to learn from decisions made in the past projects.

Abstract

The TUM Living Lab Connected Mobility (TUM LLCM) research project was initiated to support the digital transformation in the area of Smart Mobility and Smart City. The project bundles the relevant research, implementation, and innovation capabilities of the Technical University of Munich in informatics and transport research. The research project contributes to the design and implementation of open, provider-independent digital mobility platforms. The actual implementation of these platforms is carried out by commercial providers taking into account the market requirements of customer-oriented mobility solutions. This paper uses the example of the TUM LLCM project to illustrate, how the Technical University of Munich combines competences of several research fields in informatics by means of innovative use cases to achieve timely results relevant for society in close collaboration with stakeholders outside of research.
