  • The experimental design is inspired from the social probes [8], translated to the professional context. Qualitative approach : gather an in-depth undretanding with smaller but focused samples It is based on the use of treatment groups only (no control group) and on a qualitative collection of data. Example : a collaborative tool for designing public space a group of people are asked about their perceptions, opinions, beliefs and attitudes towards a product, service, concept, idea, ... Here the focus group concerned the perception of the process.

    • 1. A Case Study for Improving a Collaborative Design Process

    • 2. Mixed Reality Systems
        • New interactive environments blend real and virtual entities
        • Opportunities for interacting with complex data, more intuitively, more efficiently...
        • Major challenges for their development : variety of devices, multimodality, usability...
        • Low capitalization of knowledge and know-how
      20 avril 2011 A design method for mixed reality systems
    • 3. The Symphony method
      • Developed for Information Systems
      • Extended to support the design of mixed reality systems
      • ... While keeping each domain practices
      Functional branch Technical branch Central branch
    • 4. Symphony adapted
    • 5. Symphony adapted
      • the process facilitates the collaboration between actors from the SE and HCI domains
      • it allows designers producing consistent models.
      Symphony Objects Scenario Business specialist Usability specialist
    • 6. Case Study - Settings
      • Inspired from social probes
      • Participants: 4 groups of 1 HCI and 1 SE experts
      • Steps:
          • starting session : a questionnaire about work habits, a short introduction to the Extended Symphony Method and the example were given to the participants.
          • Working period : participants worked alone or together. They recorded their results, the time spent, their goals, their difficulties in a form.
          • Cooperative session : each group realized the cooperative activity “Description of weaving model between BO and IO” to link the HCI and SE models.
          • Working period
          • Final session : participants presented their results and during a focus group session, they gave their opinion on the process.

          • Symphony Objects:
          • “ a bridge between SE and HCI, a good synchronization point”
          • Too many models
          • Interesting and satisfying particularly for its exchanges between SE and HCI
            • Useful collaboration: “Now I understand why ones does HCI”
          • Logical and natural sequencing of activities
          • Long process
          • Too long collaborative activities
    • 8. Process Evolution Process Simplication Only cooperative activities Documentation improvement
    • 9. Conclusion
      • Case study to gain some insights about the extended Symphony process
        • Validation
        • Improvements
      • Interest of a qualitative approach
        • Towards a more systematic evaluation of IS methods
    • 10. Thanks for your attention
      • any question ?
