Understandability of Goal-Oriented Requirements Engineering Concepts for Enterprise Architects

ArchiMate is a graphical language for modelling business goals and enterprise architecture. In previous work we identified possible understandability issues with the goal-oriented notations in ArchiMate. [Problem] We investigated how understandable the goal-oriented concepts really were in two quasi-experiments with practitioners. [Principal ideas/results] Only three concepts were understood by most or all subjects; the stakeholder concept, the goal concept and the requirement concept. The other concepts were misunderstood by most of our subjects. We offer explanations for these (mis)understandings. [Contribution] This paper provides new insights into the understandability and hence usability of goal-oriented concepts by practicing enterprise architects
