Lightning Decision Jam (LDJ)

A fast-paced, highly structured workshop format that replaces open discussion with a series of individual exercises and democratic voting. It moves a team from identifying problems to selecting and prioritizing solutions in record time.

When to use Lightning Decision Jam (LDJ)

To make rapid decisions and solve problems without the circular, time-wasting nature of traditional meetings.

What it solves

Unstructured meetings, dominant voices, and 'analysis paralysis' that prevent clear outcomes.

How to run Lightning Decision Jam (LDJ), step by step

  1. Capture Problems (7 mins) - Everyone writes challenges silently.
  2. Vote on Problems (4 mins) - Use dots to find the most pressing issue.
  3. Reframe as 'How Might We' (5 mins) - Turn the top problem into a challenge.
  4. Ideate Solutions (7 mins) - Silent individual brainstorming.
  5. Vote on Solutions (4 mins) - Select the most promising ideas.
  6. Prioritize on Impact/Effort Scale (10 mins) - Plot the winners to see what to do first.

Materials needed

Facilitator tips

Variations
