Software is an essential part in the value chain of many companies. This affects not only the IT-industry itself, but nearly all German industries, as software is the main driver of many innovations. In 2014 the value created in German economy by software was similar to automotive industry. Mobility, energy, and infrastructure strongly depend on software which is not always of high quality. Critical performance or security issues for instance arise from bad software quality. During development and operations of a software system various concerns must be considered. Quality aspects are examples of concerns which may differ from one project to another. For instance, performance is highly relevant for a web shop whereas for a storage service security may be more relevant. Especially in the cloud context quality aspects like privacy can only be assessed reasonably during operations which, in contrast to aforementioned ones, makes development analysis widely unrewarding.

Further, software interacts with other domains (e.g., in Industry 4.0) like business processes, mechanics or electronics where only a subset may be relevant for a certain software project. Currently, developers and operators must apply different analysis tools for each concern. Each tool requires specific input models of different languages. Hence, the input models are not integrated and require enormous manual effort for creation and maintenance. Quality goes beyond most architecture description languages (i.e., meta-models). The commonly agreed modeling language in software engineering UML does not consider quality aspects. Even its extension MARTE is restricted only to performance. Languages and tools that comprise all possible concerns would be very large, unhandy and hard to maintain. The proposed project targets more flexibility in Model-Driven Development (MDD) by using MDD adaptation capabilities to tailor modeling languages to specific concerns. The proposal addresses the concerns quality aspect, domain, and lifecycle phase. We aim for improving efficiency and scalability of modeling and analysis approaches by focusing the effort merely on the relevant concerns and enabling easy tool customization. Key scientific contribution will be a reference architecture for specification and analysis of various concerns. We will use an iterative, case study-driven approach to co-develop foundations and their application.
