IFIP • The International Federation for Information Processing
IFIP was founded in 1960 under the auspices of UNESCO, following the First World Computer
Congress held in Paris the previous year. An umbrella organization for societies working in
information processing, IFIP's aim is two-fold: to support information processing within its
member countries and to encourage technology transfer to developing nations. As its mission
statement clearly states,
IFIP's mission is to be the leading, truly international, apolitical organization which encourages
and assists in the development, exploitation and application of information technology for the
benefit of all people.
IFIP is a non-profitmaking organization, run almost solely by 2500 volunteers. It operates
through a number of technical committees, which organize events and publications. IFJP's
events range from an international congress to local seminars, but the most important are:
• The IFIP World Computer Congress, held every second year;
• open conferences;
• working conferences.
The flagship event is the IFIP World Computer Congress, at which both invited and contributed
papers are presented. Contributed papers are rigorously refereed and the rejection rate is high.
As with the Congress, participation in the open conferences is open to all and papers may be
invited or submitted. Again, submitted papers are stringently refereed.
The working conferences are structured differently. They are usually run by a working group
and attendance is small and by invitation only. Their purpose is to create an atmosphere
conducive to innovation and development. Refereeing is less rigorous and papers are subjected
to extensive group discussion.
Publications arising from IFIP events vary. The papers presented at the IFIP World Computer
Congress and at open conferences are published as conference proceedings, while the results of
the working conferences are often published as collections of selected and edited papers.
Any national society whose primary activity is in information may apply to become a full
member of IFIP, although full membership is restricted to one society per country. Full members
are entitled to vote at the annual General Assembly, National societies preferring a less
committed involvement may apply for associate or corresponding membership. Associate
members enjoy the same benefits as full members, but without voting rights. Corresponding
members are not represented in IFIP bodies. Affiliated membership is open to non-national
societies, and individual and honorary membership schemes are also offered.

Preface
For more and more systems, software has moved from a peripheral to a
central role, replacing mechanical parts and hardware and giving the product
a competitive edge. Consequences of this trend are an increase in: the size of
software systems, the variability in software artifacts, and the importance of
software in achieving the system-level properties. Software architecture
provides the necessary abstractions for managing the resulting complexity.
We here introduce the Third Working IEEFlIFIP Conference on
Software Architecture, WICSA3. That it is already the third such conference
is in itself a clear indication that software architecture continues to be an
important topic in industrial software development and in software
engineering research. However, becoming an established field does not
mean that software architecture provides less opportunity for innovation and
new directions. On the contrary, one can identify a number of interesting
trends within software architecture research.
The first trend is that the role of the software architecture in all phases of
software development is more explicitly recognized. Whereas initially
software architecture was primarily associated with the architecture design
phase, we now see that the software architecture is treated explicitly during
development, product derivation in software product lines, at run-time, and
during system evolution. Software architecture as an artifact has been
decoupled from a particular lifecycle phase.
A second trend is explicitly relating architecture design decisions to the
requirements satisfied by these design decisions. This is particularly true of
design decisions affecting quality requirements, where one can identify
several research initiatives.
