2. We interact with documents in two separate worlds: the electronic world of the workstation, and the physical world of the desk. Interaction styles in these two worlds do not resemble each other, functions available are different, and the interaction between the two is limited. - Pierre Wellner, Xerox Researcher, 1993 “ ”

23. 27 July 2001Design History and Rationale in The Designers’ Outpost22 DR and Early-Phase Design Mostly team members communicating with each other –Informal representations Later phases involve more parties –clients, developers –Require more formal representations Design Rationale capture and retrieval for people involved in or close to the process D E S I G N R A T I O N A L E
