iStar Showcase’11: Exploring the Goals of your Systems and Businesses


June 21st, 2011, 1-5 pm

City University London, Northampton Square, London EC1V0HB, UK



As the i* modeling approach is becoming more widely known, more case

studies of practical applications are becoming available. This half-day

event targeted at practitioners aims to showcase a variety of practical

applications of i*, and to provide a forum for exchanging ideas and

experiences among users and researchers. We seek contributions for

presentations and posters demonstrating the practical use of i* modeling

in a wide variety of application domains and usage contexts. The

emphasis at this event will be on practical applicability and utility,

rather than on research novelty. Presentations from completed projects

as well as work-in-progress are welcome.


This event aimed at promoting industry awareness and adoption will

complement the iStar’11 research workshop to be held August 29-30, 2011,

co-located with the RE’11 conference in Trento, Italy.


Format (tentative)


- An overview of i* modeling (20-minute - motivations and a very

compressed tutorial)

- A round of short presentation (5 minutes each) to present highlights

of each poster, and to illustrate the diversity and breadth of usage

scenarios and application domains.

- 2-3 presentations (15-20 minutes each) to help clarify and reinforce

i* concepts and the kinds of analyses presented in the introductory

overview and tutorial.

- Poster session and socializing - for face-to-face interactions and

in-depth discussions around each poster. Participants are encouraged to

bring laptops for demos around each poster.




Please submit a proposal consisting of no more than 2 pages of text plus

2 pages of figures, including 1 to 2 sample i* models from your project.

(The models used in the poster or presentation may be variations or

excerpts of the ones in the proposal.)


The content of the proposal should include:

- Title: title of the presentation/poster

- Team: names of presenters/project participants and affiliations

- Presenter: name of person who will be presenting

- Industry involvement: nature and extent of academic/industry/business

collaboration, types of personnel involved

- Setting and context: brief description of the domain setting, and what

motivated the use of i*

- Status: status of the project (e.g., early-stage, in-progress with

some results, or completed with lessons learned)

- Benefits: benefits from using i* modeling and analysis in the project

- Lessons learned: lessons learned

- Language and variants: language variant used (vanilla i*, minor

modifications, major extensions, Tropos, GRL/URN, etc.

- Features used: what features of i* were used in the project (e.g., SD

only with a few softgoals, SR with goal model evaluation, etc.)

- Tools and methodologies: what tools and methodologies were used

- Model size: rough indication of the largest size of model used -

number of actors and intentional elements in models

- Efforts: rough estimate of person-hours used to learn and to apply i*

modeling and analysis in the project.




Since the event is aimed at the practitioner community, the

"proceedings" will consist of a compilation of slide decks and poster

files provided by the presenters. Final submission will be required by

June 8th. The proceedings will be distributed to registered participants

electronically in advance of the event.


Important dates


Submit proposals to Jennifer Horkoff <> by May 27th.

Final submission of the slide deck and/or poster will be required by

June 8th.
