Materials, and therefore material selections, influence the sustainable impact of a product from beginning to end-of-life. With improved access to material information, product designers can attain newfound insight into the sustainability implications of their design decisions. Insight to lifecycle tradeoffs requires access to both upstream and downstream information at design time. This access can be facilitated by information transparency between information representations across the lifecycle. A well-constructed Material Information Model (MIM) can provide the necessary access, and therefore the desired insight. In this paper we present an initial set of requirements that a MIM must support to provide the desired design-time information access. Using these requirements as guidelines, we then analyze several information representations currently employed for information management at various stages of the lifecycle. We compare and contrast the extent to which these representations meet the information needs of a MIM. We discuss the level to which information synthesis may be achieved given the varying degrees to which the MIM requirements are met. Finally, we introduce where synthesis challenges lie and the steps required to overcome them.
