The Lightning Decision Jam (LDJ) is a facilitation technique used to address and solve complex problems quickly and efficiently. It replaces open-ended discussions with a clear, time-boxed process, helping teams to avoid common decision-making pitfalls like unstructured debates and decision fatigue. By using a series of structured exercises, LDJ helps teams to prioritize issues, generate solutions, and decide on action steps in a democratic and efficient manner. This approach not only accelerates the decision-making process but also enhances team alignment and collaboration.
