The document describes the Lightning Decision Jam (LDJ), a 1-hour exercise based on design sprints that helps teams solve problems and make decisions quickly. The LDJ follows a process where teams identify challenges, generate solutions, vote on solutions, and prioritize the top solutions over an impact/effort scale to determine the best ones to implement. The goal is for teams to recognize problems, create solutions, and have a plan of action to work on the highest impact items in just one hour using the LDJ methodology.
