Scalability Concepts for i* Modelling and Analysis

Аннотация
Goal and agent oriented modelling techniques represent one of the major
accomplishments of the Requirements Engineering research community.
As modelling frameworks cross the boundaries between research phase prototypes
and application in complex real life projects, scalability challenges, which could not
be easily anticipated through simple example application, surface.
Models, like software products, have their own lifecycle. They go through an
initial development phase, are then validated by stakeholders and finally used for
reasoning purposes by the analysis team. We argue that each phase entails its own
scalability challenges and requires specific mechanisms to address them.
We propose an iterative, “one concern at a time“ analysis approach and present a set
of model decomposition concepts based on the i* model topology and the analysis
question at hand, to address complex model reasoning challenges. Additionally, we
offer our insights and practical experience results in dealing with complex model
development and validation difficulties.
