Dissertation Petra Becker-Pechau
| Working Title |
Architecture Aware Software Development |
| Abstract |
- Explicitly Described Architectural Information to Prevent Architectural Decay -
Software developers need explicit architectural information during the development
of software systems. This dissertation addresses the architecture of object-oriented
systems in iterative, incremental software development processes.
Pure Source code does not give enough architectural information. External architecture
descriptions are not sufficient, as architectures change during a development process
and the descriptions tend to become obsolete. But without the necessary architectural
information, architectures decay.
This dissertation defines criteria for the description of architecture information in
iterative, incremental development processes. Thereby it differentiates between the
architecture of specific software systems and the rules applied to develop and change
architectures. It analyses the shortcomings of existent external architecture description
languages and develops alternative solutions, e.g. integration of (parts of) the
architecture description into the software system. The goal is always to provide
software developers with the architectural information needed for their current task.

Dissertation Lahouaria Bendoukha
| Working Title |
Version-based description of cooperation aspects |
| Abstract |
Different aspects covering the generic term cooperation have been recently clarified in a business (and software) process. According to the proposed taxonomy we identify three main services: collaboration, coordination and communication. The goal of our doctoral work is to bring out the implicit cooperation support by focussing on collaboration aspect through version modeling and to adapt the later in order to support also the other aspects in a unifying way. We aim then to bridge the gap between both research areas: cooperation and version modeling which have so far brought several common problems to researchers in these two areas.

| Working Title |
A Proposed Guide for Taking STEPS into the Web |
| Abstract |
Web-based applications are getting increasingly important. But there is no established method for developing these systems. The aim of my dissertation is to describe challenges and problems that process models have to address when developing Web-based applications. These can be grouped to challenges that arise in the cooperation of the many different actors (e.g. programmers, users, screen designers, lawyers), problems that evolve because of the difficulties to identify the users of the system (e.g. anonymous Web users), and as a result of it the problems of gathering sound requirements for the application. In the work I proposes the adaptation of the evolutionary and participative development approach STEPS in order to overcome the challenges and shows how it will change the cooperation between the actors and stakeholder of a Web project.

| Working Title |
Participatory Design in Context of Gender Hierarchy |
| Abstract |
Today, participatory approaches are accepted methods in software development, i.e. in those cases where they
are embedded within a social system. The focus of this investigation is on the role of gender relations
within the development of software. The starting point is software development, especially its relevance
for practical use. In the first part of this study the theoretical framework is developed. Concepts of
participatory system development are illuminated within the tension of organization of work and of technology.
A theoretical framework is applied to investigate the forces within this tension, by combining the research
approaches of Participatory Software Development, Sociology of Organization and of Technology, as well as
feminist research and gender studies. Here, the main aspects are: The relationship between development of
software and context of use; the meaning of hierarchies, and the role of gender relationships in software
development and software use. Gender relationship in this sense is a concept that includes individual,
normative-symbolic, and structural dimensions (Orlikowski, Harding). The communication between technical
staff and user experts is analytically separated into the two aspects content and relationships (Watzlawick).
The second part of this manuscript is a reconstruction of two participatory requirement analysis processes.
Both projects had the goal of developing a software that supports communication and cooperation. Because
both work fields were typical occupations of women (call-center, office-work) the user participants were female.
The main question of the research was about the effects of hierarchies on software development processes,
especially of gender hierarchy. Empirical data were qualitative interviews with female users.
Especially within one project, the cooperation between the female users and male developers was investigated.
The communication between these parties was difficult and had asymmetric structures. These asymmetries were
based on hierarchical conditions. By separating the analysis of content from the analysis of relationship,
it was possible to demonstrate the effects of different hierarchies on communication and on cooperation.
Even independant of gender of actors, a gender sensitive view on conditions and processes is necessary. Here
the goal is to dismantle role-specific and gender-stereotypic expectations. In addition existing contradictions
were discovered. Suggestions are provided for concepts of participatory software development, as well as for
empowerment strategies to benefit users. The empowerment is directed towards structural change and avoidance
of discriminating gender roles. This way, conditions for action are extended and long term change is possible.

| Working Title |
Semantic enrichment of programming interfaces
|
| Abstract |
As for today their are lots of ways to describe and specify programming interfaces. Among them are severall
quite well defined, usable, and established methods. All of them have two things in common: they are strong in
means of describing static information of programming interfaces mostly on a signature level of operations, e.g.
in and out type information, exceptions etc. and they all lack possibilities to express semantics of an operation
on a formalized and standardized level.
In my work I'd like to find a way to enrich programming interfaces with semantical information. A fitting
metaphor could be the so called Rosetta Stone. The Rosetta Stone was found 1799 by a french soldier at the
Rosetta branch of the Nile River in Egypt. It was the key to decrypt hieroglyphs.
In reference to this I would like to find a way to provide Rosetta Stone to programming interfaces.
Therefore firstly a way has to be found to formally specify and to add semantic information usable and
understandable to programming interfaces. Secondly the question how do I retrieve a Rosetta Stone, especially
how to generate it from code has to be answered. Thirdly one has to think, how this additional information
could be added to a development process.

| Working Title |
Tools and Languages for Object-Oriented Framework and
Application Development following the Tools and Materials Approach.
|
| Abstract |
The research focus of this work is two-fold. First, the current culture
of software engineering based on object-oriented principles demands
sophisticated tool support, especially in the fields of analysis,
visualization and refactoring of object systems and in the construction
and documentation of object-oriented frameworks. Several new approaches
and principles in these areas are being examined and prototypically
implemented as part of this work. Second, as the architectures of large
systems are still too complex to be described just in terms of objects,
classes and inheritance, designers of object-oriented languages are
aiming at higher levels of abstraction. One such higher level of
abstraction is represented by the Tools and Materials (T&M) approach, a
set of project-proven metaphors that highly influences the vocabulary of
software engineers working with it. As part of this work the chances are
examined whether a contemporary object-oriented language can be extended
to better reflect and support the use of this vocabulary and the T&M
approach in general. The results of the first focus are also expected to
partly serve as a foundation for the second focus.
