Design reuse is an approach in which the creation of new designs is based on the identification of previously employed solutions and the incorporation of those into new contexts. This notion has been extensively studied especially by software engineers. This research seeks to support the reuse of design knowledge in the Human-Computer Interaction (HCI) community in creating new designs as it is generally argued that reuse has the potential to reduce development time and costs. Efforts to reuse design elements in HCI, often in the form of design patterns, are slowly emerging.

This work seeks to facilitate the reuse of design knowledge in the form of claims. To achieve this goal, the notion of claim relationships—descriptions of connections between claims that emerge in design—is introduced as a mechanism to facilitate reuse. Claims relationships can be used to connect a collection of reusable claims so that they can be searched, understood, tailored, and integrated into new designs. A method for how to use the relationships is presented to aid in the creation of scenarios. Through a series of studies starting from the use of relationships to locate and reuse claims to the use of cards sets incorporating images and rationale for storyboards, the potential for relationships is demonstrated.

These works inform the design and evaluation of a storyboarding tool called PIC-UP. PIC-UP is introduced as an example of how relationships can be utilized in the creation of storyboards made of reusable artifacts in the form of claims. Studies of PIC-UP position the tool as one that enables the reuse through the use of a storyboarding guide and social navigation by collecting and sharing claims. It shows potential in aiding novice and non-designers and can serve as a communication tool.
