In this paper, we introduce the application of rigorous analysis procedures to goal models in order to provide several benefits beyond the initial act of modelling. Such analysis can allow modellers to assess the satisfaction of goals, facilitate evaluation of high-level design alternatives, help analysts decide on the high-level requirements and design of(More)
In November 1999, the International Telecommunication Union (ITU-T, SG 17) initiated a question on the standardization of a User Requirements Notation (URN) for complex reactive, distributed, and dynamic systems and applications. URN is intended to be standardized by September 2003. This paper presents the motivations behind URN, its objectives, and the(More)
Although model-driven engineering (MDE) is now an established approach for developing complex software systems, it has not been universally adopted by the software industry. In order to better understand the reasons for this, as well as to identify future opportunities for MDE, we carried out a week-long design thinking experiment with 15 MDE experts.(More)
The User Requirements Notation (URN), standardized by the International Telecommunication Union in 2008, is used to model and analyze requirements with goals and scenarios. This paper describes the first ten years of development of URN, and discusses ongoing efforts targeting the next ten years. We did a study inspired by the systematic literature review(More)
Once aspects have been identified during requirements engineering activities, the behaviour, structure, and pointcut expressions of aspects need to be modeled unobtrusively at the requirements level, allowing the engineer to seamlessly focus either on the behaviour and structure of the system without aspects or the combined behaviour and structure.(More)
A UML PROFILE FOR GOALORIENTED MODELLING The Unified Modeling Language (UML) is a standard for visual modelling. We can design abstract models by using its elements. The semantic scope of the UML elements is very broad, and they are not fully addressing the needs of some modelling domains, including the modelling of goals and non-functional requirements(More)
