How is a designer therefore to reason about these divergent concerns that motivate the way different stakeholders view the system they are designing? This paper discusses a simple graphical device, called a rich picture, that has been found to be useful in this respect. A rich picture is a cartoon-like representation that identifies all the stakeholders, their concerns, and some of the structure underlying the work context. A rich picture is a tool for recording and reasoning about these aspects of the work context, in particular, how they should affect the design. It is a tool in the sense that a notation or representation is a tool. Rich pictures have been used as an element of various methods. The next section briefly explains the origin of rich pictures in the Soft Systems Methodology and how they look. The sections thereafter sketch some examples of how they may be used in HCI. A rich picture is a small but effective idea. It can be incorporated into any design process. Perhaps it would be useful in yours.
