Business: designing with users in Internet time

Abstract

You have three weeks to design an ecommerce application. Or three months to launch a "next-generation" website for a top video game publisher, with a new identity system, an architecture that integrates dozens of new acquisitions, and immersive lowband interactions. How can you design with users when facing intense time constraints that require simultaneous discovery user research and business strategy? Or simultaneous usage scenario development with the creation of interaction maps for a new digital service?
