Supported Process: Design Process in small teams (distributed)
=> Sketching is important for design processses
=> Group sketching with shared drawing tools
Fokus:
Idea Management in shared drawing tools.
Motivation:
No own empirical results. Argumentation is based on results of other studies that characterize the design process as chaotic => need for management.
Goal: Architecture for idea management in shared drawing tools
Methodical Approach:
Research Studies on Group Design Activities and Design Methodology => Collect Group Behavior Data => Study and Understand to generate a taxonomy of group idea management processes => Derive user Requiremets for supporting group idea management => Develop architecture (CaveDraw)
Results:
- Taxonomy of group idea management processes (list of recurring process patterns):
* Agree and add on the suggested idea
* Agree and subdivide the suggested idea
* Modify the suggested idea
* Scratch and restart
* Agree and wait
* Compare and consolidate
* Deprivatize design ideas
- CaveDraw shared drawing package
- Layer-based
- All users can work on different layers on the same time.
- Pointer to point on items
- Definition of five critical factors for idea management (argumentation unknown):
* Work Allocation: split between individual and group, personal design space?
* Design Integration: how can data from the personal space be integrated
* Design Ownership:
* Design Recall: Undo-possibilites, versioning
* Space Sharing: amount of workspace is limited, if a big group acts on the workspace, the space can quickly be full.
- User Requirements drawn from taxonomy:
- Drawing of user requirements from each of the critical factors perspectives
- Argumentation that a layer based-approach satisfies the user requirements..
