Lightning Decision Jam (LDJ)

A rapid, structured decision-making framework designed to replace open-ended brainstorming with a disciplined process. It moves teams from problem identification to actionable solutions by minimizing circular discussion and maximizing individual contribution.

When to use Lightning Decision Jam (LDJ)

Ideal for teams experiencing 'meeting fatigue,' circular discussions, or when a group needs to reach a consensus on specific project hurdles quickly.

How Lightning Decision Jam (LDJ) works

Facilitators can use this as a standalone 'unblocking' session or integrate it into larger design thinking workshops to accelerate the transition from problem discovery to execution.

Phases of Lightning Decision Jam (LDJ)

  1. Capture Problems: Everyone silently writes problems or challenges on sticky notes, one per note, in a short timebox. There is no discussion; the facilitator keeps people writing independently.
  2. Prioritize Problems (Voting): Participants silently place dots on the problems they think matter most. The facilitator ranks the notes by votes and selects the top problem or problems to work on.
  3. Reframe Problems as Challenges (How Might We): The top problem is rewritten as a 'How might we...' question that invites solutions without prescribing one. The facilitator writes the agreed wording where everyone can see it.
  4. Ideate Solutions: Each person silently writes as many solutions to the challenge as they can, one per note. No discussion or judgement; quantity is the aim.
  5. Prioritize Solutions (Voting): Participants dot-vote on the solutions they think are most worth trying. The facilitator orders them by votes to shortlist the strongest options.
  6. Decide What to Execute (Impact/Effort Matrix): The shortlisted solutions are placed on an impact and effort grid, with the facilitator moving notes as the group agrees. High-impact, low-effort solutions are chosen to act on first.
  7. Make Solutions Actionable: For each chosen solution, the group defines the first concrete step, an owner and a timeframe, often testable within a week or two. The facilitator records these as the session output.

Key principles

  • Working Together, Alone (individual ideation before group sharing)
  • Structured process over open discussion
  • Speed over perfection
  • Democratized decision-making through dot-voting
  • Tangible outcomes over abstract ideas

Best for

  • Rapid problem-solving
  • Team alignment
  • Innovation and ideation
  • Action-oriented decision making

Considerations

  • Requires a strict timekeeper to maintain momentum
  • Effectiveness depends on having the right stakeholders in the room
  • May require follow-up sessions for highly complex, systemic issues that cannot be solved in a single hour
