Tool maintenance in the context of CoEUD

• CoEUD - Cooperative End-User-Development
• Focus on End-User-Development and tool
  maintenance
• Deep insight in handling component based systems
• Focus on Eclipse / Collaborative Eclipse
  tailoring
• Several Use-Cases in small and medium-sized
  businesses of the German software industry

DESY Controlling technical facilities

• General socio-technical context
• Long tradition in visual programming
• User have strong expertise regarding their
  domain
• Heterogeneous IT-landscape causes problems
• usage (inconsistent Look and Feel, )
• maintenance (several programming languages, )
• Cooperation and synergies (applications often
  consider only the local context, )

• Concept of the Control System Studio
• Development of an easy extendable integration
  framework based on Eclipse RCP
• CSS as an infrastructure for independent and
  controllable data access
• Stratification along a gentle slope of
  complexity
• EUD for normal users (e.g. Construction of
  displays via WYSIWYG editor, )
• EUD for semi-professionals (Development of
  localised extension via Eclipse Extension
  mechanism, )
• EUD for professionals (Development of general CSS
  application without starting from the beginning)

Appropriation support in the scope of CoEUD

• User
• Technicians at the German Electron Synchrotron
  DESY
• Field of work
• Monitoring and controlling complex facilities
  used for research in partial physics (e.g.
  temperature, pressure,..)
• Technicians are able to construct their own
  controlling artefacts by graphic components

Open Question for Eclipse CSS How to support the
sharing and appropriationof tailored artifacts
10
Cooperative tool modification

• Sharing and appropriate components and tailored
  artefacts
• in the case of e-Science and Eclipse CSS it is an
  oncoming issue
• in the case of Software Development and Eclipse
  IDE it is an ongoing issue
• Our suggestion Collaborative e-Science can learn
  a lot from the appropriation practices of Eclipse
  IDE

11
Method business ethnography

• Sample
• literature research
• interviews (45 60 min)
• participating observations of developers
• analyses
• planning interventions
• cooperative discussions and validation of the
  results

12
Outcome I Toolmodifikation as a activity problem

• Theoretical framing
• Better understanding of workbench modification
• Separation of different arenas
• Group based appropriation as an activity problem
  with different aspects

13
Outcome II Tool modification as an activity
problem

• Tool modification as an activity problem which
  has to deal with different interests
• Parallel installation of eclipse versions
• Preservation of tool competence vs.
  over-directed tool maintenance

14
Ergebnis II Toolmodifikation als
Handlungsproblem

• Toolmodifikation als stetiges ausbalancieren von
  unterschiedlichen Motiven
• Parallelinstallationen von Eclipse
• Bewahrung von Toolkompetenz vs. fremdbestimmte
  Werkzeugpflege
