Clarifying Goal Models
Jureta, I.J. and Faulkner, S.
Representation and reasoning about information system
(IS) requirements is facilitated with the use of
goal models to describe the desired and undesired IS
behaviors. One difficulty in goal modeling is arriving
at a shared understanding of a goal model instance,
mainly due to different backgrounds of the
system stakeholders who participate in modeling, and
the subsequent disparate use of terminology. Lack
of shared understanding, or, in other words, the
presence of multiple interpretations entails no guarantee
that stakeholders' expectations expressed in
the model instance will be appropriately understood
during the subsequent steps of system development.
Among the many potential causes of multiple interpretations,
this paper focuses on a critical set of such
causes, namely: ambiguity, overgenerality, synonymy,
and vagueness of information represented in instances
of goal modeling primitives. The 'Goal Clarification
Method' is suggested to guide the identification of
unclear information and the subsequent clarification
thereof. |
