I. Lu, and M. Mantei. Proceedings of the Second European Conference on Computer-Supported
Cooperative Work, page 97-112. Springer, (1991)Setting: 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..
