In my Parti & the Design Sandwich talk at the Interaction 2009 conference in Vancouver, Canada I outlined a structure to enable interaction designers to move toward a holistic product design in the face of many stakeholders, cross-functional groups, and diverse audiences. Full video of my talk and slides:
In architecture, parti refers to the underlying concept of a building. Will it be a public structure that provides safety or a commercial building focused on customer up-selling?
Design principles are the guiding light for any parti. They articulate the fundamental goals that all decisions can be measured against and thereby keep the pieces of a project moving toward an integrated whole. But design principles are not enough.
Every design consideration has a set of opportunities and limitations that can either add to or detract from the parti. Designers who want to bring coherent visions to life need to learn the detailed ins and outs of design considerations so they can select the best solutions from the options available.
This combination of design principles at the top and design considerations at the bottom allows interaction designers to fill in the middle with meaningful structures that enable people and organizations to interact, communicate, and get things done.
In this talk, Luke Wroblewski will illustrate how the World’s most accessed Web page, yahoo.com, was redesigned with a parti and the design sandwich.
