The document describes a design sprint workshop for improving the way international travelers exchange local and foreign currency. It discusses the design sprint process, which includes understanding user needs through research and interviews, defining the problem, diverging through brainstorming, converging on ideas through voting and prioritization, prototyping top concepts, and validating solutions. The workshop participants will experience a design sprint by designing an Android app for exchanging currency, with deliverables of sketches and user flows. The sprint follows typical stages - understand, define, diverge, converge, prototype, and validate - to collaboratively and quickly design user-centered solutions.
