An infographic model is proposed to account for the operation of systems within their information environments. Infographics is a communication paradigm used to indicate the clustering of information processing variables in communication systems. Four propositions concerning environmental uncertainty and internal communication network complexity, derived from the more extensive model, are tested at the group level of analysis in three different settings: a U.S. bank, two Korean villages, and a U.S. retiretment community. Results show strong support across all three systems for the predicted positive relationship between openness and connectivity, and the predicted negative relationship between size and connectivity. The proposed relationships between zone size and connectivity and zone integration and connectivity receive mixed support. (Author)
