SYMPOSIUM TOPIC
---------------
Due to the size and complexity of today's systems and the desire to achieve
better quality, for example, in robustness, flexibility, time-to-market,
etc, software development is becoming an increasingly complex discipline. In
particular, the activity of architectural design of software systems becomes
of increasing importance. The design of the architecture has a large
influence on the quality of the resulting system, but this process is still
difficult and cumbersome. During the last decades, software architecture
development methods, tools and approaches have been introduced to enhance
this insight. This symposium aims at bringing together practitioners and
researchers to achieve a better understanding of the problems of designing
high quality software architectures and how they appear in practice. In
addition, experts present new insights in addressing these problems. Also,
significant attention will be paid to the transfer of research results to an
industrial setting.
The symposium "Recent Developments in High Quality Architecture Design"
contributes to an exchange of expertise in the field of high quality
software architecture design. Top researchers in the field of architecture
design will discuss new insights, share their experience in the application
of advanced design concepts in practical situations, and will discuss the
important trade-offs among software quality attributes. The symposium will
be concluded with an interactive panel discussing the benefits and obstacles
of applying aspects in mainstream software development.

DESCRIPTION OF THE SYMPOSIUM CONTENT
TALKS
=====
"Challenges in Designing High-Quality Architectures"
by Mehmet Aksit - Universiteit Twente, University of Twente
-------------------------------------------------------------------------
Designing high-quality architectures demands from us finding adequate
solutions to the following problems: What are the relevant
quality-attributes? How to define and measure them? How do we know which
quality-attributes are needed? How do we steer the architecture design
processes so that the desired quality attributes are eventually fulfilled?
How do we balance multiple quality attributes if they are conflicting? How
do we map architectures to feasible realizations? In this talk we will
outline these challenges from the perspective of the state-of-the-art
techniques and our research contributions.
"Semantics-based Composition and Analysis of Requirements"
by Awais Rashid - University of Lancaster, United Kingdom
----------------------------------------------------------------
In this talk, I will discuss the limitations of the current syntactic
composition mechanisms in requirements engineering. I will highlight that
such composition mechanisms not only increase coupling between concerns but
are also insufficient to capture the intentionality of the concern
compositions. Furthermore, they force the requirements engineer to reason
about semantic influences and trade-offs among concerns from a syntactic
perspective. I will present a requirements description language (RDL) that
enriches the existing natural language requirements specification with
semantic information derived from the semantics of the natural language
itself. Composition specifications are written based on these semantics
rather than requirements syntax hence providing improved means for
expressing the intentionality of the composition, in turn facilitating
semantics-based reasoning about concern influences and trade-offs. I will
also discuss the practicality of the use of this RDL by outlining the
automation support for requirements annotation (realized as an extension of
the Wmatrix natural language processing tool suite) to expose the semantics
which are in turn utilized to facilitate composition and analysis (supported
by the MRAT tool).
"Improving Architecture Competence"
by Paul Clements - Software Engineering Institute, United States
----------------------------------------------------------------
High-quality architecture design results first and foremost from
individuals, teams, and organizations that are highly competence to produce
them. The field of software architecture has long (and appropriately)
concentrated on improving the technical aspects of architecture -- design,
evaluation, documentation, reengineering, and the like -- but in some parts
of the field, attention is now turning to those who produce architectures.
This talk will highlight a project at the Software Engineering Institute in
measuring and improving the competence of individual architects,
architecture teams, and organizations that rely on high-quality
architectures for their livelihood. The project is taking a multi-faceted
approach, investigating organizational learning, organizational coordination
mechanisms, individual human competence theories and models, and a
duties-skills-knowledge approach to improving how architects do what they
do.
"Xlinkit: what we did and where we want to go"
by Anthony Finkelstein - University College London, United Kingdom
----------------------------------------------------------------
This talk will present xlinkit: a tool for checking constraints across
distributed data in software engineering. It will look at how the tool has
been realised in a commercial setting and will examine directions for the
further development of xlinkit.
"Models of Computational Intelligence for Quantitative Software Engineering"
by Witold Pedrycz - University of Alberta, Canada
----------------------------------------------------------------
In Quantitative Software Engineering, being critical to many pursuits of
software development including cost estimation, complexity assessment,
reliability prediction and alike, we are faced with an array of essential
challenges. Quite often we encounter very limited data sets of heterogeneous
nature including numeric entities as well as subjective expert's opinions
and judgments. In this study, we elaborate on the development of models of
software processes and software constructs in the framework of Computational
Intelligence (CI), discuss their main features, and demonstrate the
relevance of those in quantitative constructs of Software Engineering. In
particular, we elaborate on interpretability of models associated inherently
with the logic nature of fuzzy set-based architectures. Similarly, it is
demonstrated how heterogeneous data can be captured through the mechanisms
of evolutionary optimization and learning capabilities residing with the
environment of neurocomputing.
"Imperfect Information in Software Design Processes"
by Joost Noppen - University of Twente, The Netherlands
----------------------------------------------------------------
The process of designing high-quality software systems is one of the major
issues in software engineering research. Over the years, this has resulted
in numerous design methods, each with specific qualities and drawbacks.
Although the current software methods have largely proven their
applicability, unfortunately they naturally suffer from the existence of
imperfect information.
Imperfection during software design is the occurrence of information, which
is uncertain or incomplete to a certain degree. This can have many different
causes, such as for instance incomplete information sources or an imprecise
view of what the system should do. The existence of imperfection makes the
design processes difficult to apply, since such information typically has
one or more elements that are ambiguous in their interpretation. When a
system is designed by using only one of the possible interpretations, there
is a risk that the interpretation turns out to be wrong and the need to
redesign the system. Imperfection is an inherent problem of almost every
design process as well. But rather than trying to model the imperfection
that inevitably exists, imperfection is generally neglected by making
explicit and crisp assumptions, which may eventually result in wrong design
decisions.
In this presentation, we identify the problems in the two areas in which
imperfect information can manifest itself, namely in contextual information
(predominantly requirement specifications) and in software design
activities. Based on this, we propose generic extensions to software design
processes for modeling imperfect information. In our proposed method we have
used techniques from probability theory and fuzzy set theory, to ensure that
we capture the relevant properties of the imperfect information.
