In this paper, we present a novel visualization frameworkÂ for product and supply chain metadata in the context ofÂ redesign-related decision scenarios. Our framework isÂ based on the idea of overlaying product-related metadataÂ onto interactive graph representations of a supply chainÂ and its associated product architecture. By coupling environmentalÂ data with graph-based visualizations of productÂ architecture, our framework provides a novel decisionÂ platform for expert designers. Here, the user can balanceÂ the advantages of a redesign opportunity and manage theÂ associated risk on the product and supply chain. For demonstration,Â we present ViSER, an interactive visualization toolÂ that provides an interface consisting of different mutuallyÂ coordinated views providing multiple perspectives on aÂ particular supply chain presentation. To explore the utilityÂ of ViSER, we conduct a domain expert exploration usingÂ a case study of peripheral computer equipment. ResultsÂ indicate that ViSER enables new affordances within theÂ decision making process for supply chain redesign.

Screen capture of the ViSER tool. Each feature of the ViSER platform is described as follows: (A) a directed graph that representsÂ the supply chain network as the edges connected to the selected nodes are shown in red, (B) a representation of the product system graphÂ oriented by a combination of force directed physics and user manipulation, (C) a panel with detailed information about the most recentlyÂ selected item, (D) sparklines for each criterion with outliers shown in red, (E) a boxplot that provides a range of single score impacts perÂ selection, (F) a comparison chart of impact categories for selected nodes, (G) change propagation results for selected nodes, and (H) theÂ profile of selected node attributes, ecotoxicity.
