Dear Readers,
This special issue of JOT contains revised versions of the papers
presented at the “Open Issues in Industrial Use Case Modeling” workshop,
held in conjunction with the UML 2004 Conference. The conference
took place in Lisbon, Portugal, from October 10 to 15, and the
workshop was held during the first day of the conference.
Use Cases have achieved wide use as a specification tool for
observable behavior of systems. However, there is still much
controversy, inconsistent use, and free-flowing interpretations
of use case models, in fact, not even experts widely recognized
in the community agree on the meaning of concepts. Consequently,
use case models are dangerously ambiguous, and there is an
unnecessary divergence of practice.
The purpose of the workshop was to identify and characterize
some sources of ambiguity. It gathered specialists from academia
and industry involved in modeling use cases to exchange ideas
and proposals, with an eye to both clear definition and practical
application. Some presented topics were discussed in-depth
(the UML metamodel for use cases, use case instances, use
cases in
MDD/MDA, use case model vs. conceptual model, and tools for
use cases specification), while others were left as open
issues for
future research. We hope our suggestions will be useful to
improve the understanding of use cases, and stimulate further
research
to reach a stronger coupling between the use case model and
other static, behavioral and architectural models.
After the presentation of the papers, the workshop continued
with discussions and synthesis work, trying to reach agreement
wherever it was possible. A full account of these workshop
discussions can be found in the Workshop Report published
in the proceedings
of the UML 2004 Satellite Activities (Springer LNCS 3297).
The workshop discussions were extremely participative and
fruitful. This workshop has been the first in a series
of Workshops on
Use Case Modeling (WUsCaM) that will be continued at
future UML Conferences (from now on called MoDELS Conference).

web sites (http://www.ie.inf.uc3m.es/uml2004-ws6/ and http://www.ie.inf.uc3m.es/wuscam-05/).
Finally, we would like to thank the authors for submitting
these contributions and the programme committee for their
reviews.
