The document discusses lean user experience design and rapid prototyping. It outlines an agenda covering current status, who user experience designers are, lean UX, storytelling, sketching, hi-fidelity wireframing, and why the author likes using Keynote for prototyping. It then discusses moving from traditional UX processes focused on deliverables to a leaner process centered around prototyping and testing designs to understand user experiences. Sketching and interactive prototyping are presented as ways to tell stories and get feedback earlier in the design process.
