Abstract. Over the last three years the iStar community has worked
together to come up with a standardized version of the i* modeling lan-
guage. Although i* has become a prominent requirements modeling lan-
guage, language use and interpretation vary widely. The aim of the iStar
community effort was to avoid the confusion of multiple versions and
interpretations of Eric Yu’s original i* language – a barrier to teaching
and industrial application, among other things. After many meetings, ex-
changes, and discussions, the iStar 2.0 Language Guide was released in
May of 2016. This guide introduces the iStar 2.0 core language, evolving
the basic concepts of i* into a consistent and clear set of core concepts,
upon which to build future work and to base goal-oriented teaching mate-
rials. This talk provides a brief overview of the iStar 2.0 core, but focuses
mainly on the process and decision making behind the production of the
reformed language. A timeline of meetings and actions is provided. The
talk highlights a number of key decision points, including the softgoals
vs. qualities, means-ends links, and actor associations links. For each
case, the options and arguments are provided, with a description of the
final decisions. The goal here is not to reopen the debate, so much as
to provide a record of rationale for the choices. Areas of future work are
outlined, including revision of the core based on empirical feedback and
the production of teaching materials.
