Further analysis of the early results suggests a natural intrinsic grammar is manifested within rich pictures in terms of relationships, icons, context and connectors. Preliminary results suggest there are a set of distinguishable icons and shapes that are generic across all rich pictures regardless of domain. The comparative results are set against the ongoing empirically grounded rich picture research within Heriot-Watt University in Scotland. This paper compares 2 rich picture workshops: the diagramming workshop at the Open University eSTEeM Diagramming Colloquium in March 2012 and a workshop held in Heriot Watt University in February 2012. Secondly, to develop further ongoing research which suggests rich picture construction can be aided by providing an icon legend. The aim of this paper is twofold: firstly to report upon an observation of a large scale collaborative diagramming workshop and compare the resulting pictures with a previous workshop study. This paper looks at the benefits and interpretative risks when using rich pictures for system understanding. Simple graphics can be rapidly communicated, processed and transmitted within a large and culturally diverse constituency. A visual language of pictures, such as the rich picture used in the Soft System Methodology, offers a way of global communication that far exceeds the limitations of text and speech.
