This document provides an overview of a 48-hour event called the Global Service Jam where participants design new services. It includes tips for participants such as keeping ideas small in scope, being playful yet focused, trying new techniques, emphasizing doing over just talking, engaging in co-creation, and not becoming too attached to initial ideas. Locations of past jams and hashtags for sharing on social media are also listed. The overall purpose is to give attendees guidance on getting the most out of the jam by designing innovative new services within the tight 48-hour timeframe.
