The iStar workshop series is dedicated to the discussion of concepts, methods, techniques, tools, and applications associated with i* (iStar) and related goal modelling frameworks and approaches (Tropos, GRL, among others). As in previous editions, the objective of the workshop is to provide a unique opportunity for researchers in the area to exchange ideas, compare notes, promote interactions, and forge new collaborations. Expected outcomes include the communication of early results and new ideas to fellow researchers for feedback, the identification of the current problems and promising future research directions and the fostering of awareness, collaboration and interoperability in the area of tool development.

The focus of the iStar workshop series is quite specific and provides an additional forum for the RE community to exchange the latest ideas and research on goal modeling. In line with the RE’20 conference theme “Requirements Engineering for a Digital World”, this edition of the iStar workshop series also seeks to explore how i* may be best applied in the Digital World. For example, how does i* relate to other frameworks and approaches that are relevant in the Digital World? What are the objectives of these other approaches, and how can they complement i*? How can they interact and support the understanding of specific domains and the design of systems?
