    Public sector information furnishes a valuable information resource for many businesses. Thus, the design of value chains across different stakeholders and corresponding business models capitalising on public sector information is a challenge. Business models have been investigated mostly in the realms of eCommerce and rarely for public private partnerships. Thus, they are strongly tailored to financial incentives. So far, the modelling of policies and arguments have been neglected in eCommerce approaches. This paper describes a new modelling method named BMeG (Business Models for eGovernment) supporting the planning of business models for eGovernment services. BMeG facilitates the modelling of options of value chains with public and private partners, their relationships with individual advantages and disadvantages for policies. Hence, BMeG unveils business opportunities and their rationales.

    Since nowadays more and more control systems are realised within software on electronic control units, a conceptual integration of control systems engineering and software engineering must be aimed at. Within this work, we build on a recent proposal to use the software requirements formalism i* to enable a combined investigation of control systems' and software requirements. While i*'s modelling means have turned out to be sufficiently expressive, two characteristics of control systems still need to be addressed: firstly, how to incorporate domain knowledge especially about the system to be controlled in the requirements development process and secondly, how to specifically support small and medium-sized companies (SMEs) that are the main driver for innovations in this domain. Due to their innovativeness and flexibility, the SMEs usually follow a project-oriented customer-specific development approach. To be nonetheless cost-effective, especially during the offer development phase, we develop a mechanism and a tool to compare a current requirements model with requirements models of control systems from earlier projects. Altogether this reduces time and increases reliability in regard to the identification of reusable software artefacts.
