  1. 1. A Case Study for Improving a Collaborative Design Process <ul><li>Sophie Dupuy-Chessa </li></ul><ul><li>Nadine Mandran </li></ul><ul><li>Guillaume Godet-Bar </li></ul><ul><li>Dominique Rieu </li></ul><ul><li>Laboratory of Informatics Grenoble, France </li></ul>LIG-SIGMA research group E ngineering H uman- C omputer I nteraction ( EHCI ) research group
  2. 2. Mixed Reality Systems <ul><ul><li>New interactive environments blend real and virtual entities </li></ul></ul><ul><ul><li>Opportunities for interacting with complex data, more intuitively, more efficiently... </li></ul></ul><ul><ul><li>Major challenges for their development : variety of devices, multimodality, usability... </li></ul></ul><ul><ul><li>Low capitalization of knowledge and know-how </li></ul></ul>20 avril 2011 A design method for mixed reality systems
  3. 3. The Symphony method <ul><li>Developed for Information Systems </li></ul><ul><li>Extended to support the design of mixed reality systems </li></ul><ul><li>... While keeping each domain practices </li></ul>Functional branch Technical branch Central branch
  4. 4. Symphony adapted
  5. 5. Symphony adapted <ul><li>the process facilitates the collaboration between actors from the SE and HCI domains </li></ul><ul><li>it allows designers producing consistent models. </li></ul>Symphony Objects Scenario Business specialist Usability specialist
  6. 6. Case Study - Settings <ul><li>Inspired from social probes </li></ul><ul><li>Participants: 4 groups of 1 HCI and 1 SE experts </li></ul><ul><li>Steps: </li></ul><ul><ul><ul><li>starting session : a questionnaire about work habits, a short introduction to the Extended Symphony Method and the example were given to the participants. </li></ul></ul></ul><ul><ul><ul><li>Working period : participants worked alone or together. They recorded their results, the time spent, their goals, their difficulties in a form. </li></ul></ul></ul><ul><ul><ul><li>Cooperative session : each group realized the cooperative activity “Description of weaving model between BO and IO” to link the HCI and SE models. </li></ul></ul></ul><ul><ul><ul><li>Working period </li></ul></ul></ul><ul><ul><ul><li>Final session : participants presented their results and during a focus group session, they gave their opinion on the process. </li></ul></ul></ul>One week
  7. 7. Case Study - Results Performance Perceptions Intentions Behaviour Intention to use Perceived Ease of Use Perceived Usefulness Actual Efficiency Actual Effective-ness Actual Usage Moody’s Evaluation Model <ul><ul><ul><li>Symphony Objects: </li></ul></ul></ul><ul><ul><ul><li>“ a bridge between SE and HCI, a good synchronization point” </li></ul></ul></ul><ul><ul><ul><li>Too many models </li></ul></ul></ul><ul><ul><ul><li>Interesting and satisfying particularly for its exchanges between SE and HCI </li></ul></ul></ul><ul><ul><ul><ul><li>Useful collaboration: “Now I understand why ones does HCI” </li></ul></ul></ul></ul><ul><ul><ul><li>Logical and natural sequencing of activities </li></ul></ul></ul><ul><ul><ul><li>Long process </li></ul></ul></ul><ul><ul><ul><li>Too long collaborative activities </li></ul></ul></ul>
  8. 8. Process Evolution Process Simplication Only cooperative activities Documentation improvement
  9. 9. Conclusion <ul><li>Case study to gain some insights about the extended Symphony process </li></ul><ul><ul><li>Validation </li></ul></ul><ul><ul><li>Improvements </li></ul></ul><ul><li>Interest of a qualitative approach </li></ul><ul><ul><li>Towards a more systematic evaluation of IS methods </li></ul></ul>
