Context. Companies adopt hybrid development models consisting in an integration of agile methodologies and Human-Centered Design (HCD) with the aim to increase value delivery as well as to reduce time to market. This has an impact on how Requirements Engineering (RE) is carried out in an agile environment. To this end, people apply different kind of agile techniques like artifacts, meetings, methods and roles. In this context, companies often struggle with improving their value chain in a systematic manner, since guidelines for choosing an appropriate set of agile techniques are missing.

Objective. The vision of this PhD thesis is to build a framework for modeling agile RE. Organizations benefit from implementing this framework by increasing their value delivery (organization external) and improving collaboration (organization internal).

Method. We followed an inductive research approach, where we used the learning from several studies to create the framework. In the beginning, we carried out a Systematic Literature Review (SLR) to analyze the state of the art of agile RE with focus on user and stakeholder involvement. Subsequently, we created the agile RE metamodel, which evolved iteratively along the consecutively studies. Based on the metamodel, we defined a suitable profile to be used to create domain specific models according to the organizational environment. Moreover, we conducted a Delphi study in order to identify the most important problems industry has to face up today in terms of agile RE. The results were used as input for a systematic pattern mining process, which was utilized to create agile RE patterns.

Results. The framework for modeling agile RE consists of three main components: i) agile RE metamodel, which can be used to analyze the organizational environment in terms of value delivery ii) catalog of agile RE problems, which allows detecting recurring problems in terms of agile RE iii) catalog of agile RE patterns, which allows to solve the detected problems. The agile RE metamodel comes with a profile, which can be used to deviate domain specific models. In addition, we created tool support for the framework by means of a web application (agileRE.org), which allows us to share knowledge and best practices for agile RE. Furthermore, we proved how the framework could be applied in industry by means of case studies conducted in Germany and in Spain.

Conclusion. The framework for modeling agile RE empowers companies to improve their organizational environments in terms of value delivery and collaboration. Companies can utilize the framework for improving their value chain in a systematic manner. In particular, it gives guidance for choosing appropriate agile techniques that fit the changing needs of the organizational environment. In addition, we can state that the framework is applicable internationally.
