One of the major challenges in requirements engineering arises from the fact that software systems do not exist in isolation, as they are used in a social and organizational context. Therefore, fitting social and organizational requirements is often critical for the success of the systems. It is widely acknowledged that adopting a sociotechnical approach to system development leads to systems that are more acceptable to end users, and delivers better value for stakeholders. The group of socio- technical requirements includes requirements to ensure trustworthiness and legal- compatibility. Legal compatibility aims at the greatest possible compliance with higher-order legal goals and extends legal-conformity which refers to the prevention of lawlessness. Another important factor to raise user acceptance in sociotechnical systems is the users’ trust in the system. Because information systems are increasingly automated and opaque the users have no ability to know what happens exactly inside a system. This lack of effective regulation of the system generates complexity. People try to reduce social complexity by the adoption of trust. This is caused by the inherent need of people to understand others and their surroundings. By trusting, people reduce their perceived social complexity by a belief allowing the people to act in uncertain environments, albeit this belief may be irrational and may lead to vulnerable behavior. Hence, many stakeholders from various disciplines are involved in the requirement engineering activities when developing sociotechnical systems. However, some failings of sociotechnical systems engineering can be attributed to this multidisciplinary nature of system development. These failures result from problems in understanding and communication between stakeholders coming from different disciplines, e.g. social vs. technical. During requirements analysis, some disciplines do not fully understand what other disciplines can do, and they fail to deliver products that can be used by others. To overcome challenges in socio-technical systems engineering researcher suggest that an individual (or team) should have has a working knowledge and appreciation of what other disciplines have to offer, and can communicate effectively with them. The objective of the dissertation is to develop a pattern based approach that helps requirements analysts in analyzing requirements, thus making them comprehensible to all stakeholders in order to get a requirements specification approved by all of them. Due to the importance for sociotechnical systems engineering, this research developed 15 requirement patterns for legal-compatibility and 30 for trustworthiness. For the
