It is unfortunate that so much of this knowledge is not fully reused by designers today. To encourage the use of previously identified HCI knowledge, we propose a model of reuse building on Carroll?s notion of claims, design knowledge components that capture the positive and negative psychological effects of design features. We address four challenges associated with reuse in a library of claims, adopted from software engineering?a discipline in which the notion of reuse has been prevalent for quite some time. Building on Krueger?s definition of reuse and his conceptualization of four key aspects?abstraction, selection, specification, and integration?we propose a reuse approach based on incorporating these four aspects into the design process. To abstract, select, specify and integrate claims, we identify claim relationships, descriptions of connections between claims. We portray how claim relationships can be used to aid in identifying claim types, searching for claims, creating new claims, and aggregating claims. By integrating relationships into a claims library, we demonstrate how they can be applied to assist claims reuse and present studies related to each application of the relationships.application/pdfenIn CopyrightUsability engineeringHuman-computer interactionTechnical reportTR-06-05http://eprints.cs.vt.edu/archive/00000742/01/wmcl-hci.pdf
