Lean Coffee

Lean Coffee is a structured, participant-driven meeting format designed to eliminate the waste of traditional agendas by allowing the group to democratically build and prioritize the discussion topics in real-time. It utilizes visual management tools and strict timeboxing to ensure conversations remain productive, engaging, and relevant to all attendees.

When to use Lean Coffee

Most effective in environments where participant engagement is critical, such as community of practice meetups, team retrospectives, staff meetings, or 'unconference' sessions where the specific needs of the audience are not known in advance.

How Lean Coffee works

Facilitators can integrate Lean Coffee as a standalone session for peer-to-peer learning or as a module within a larger workshop to address emergent questions, conduct retrospectives, or facilitate decentralized brainstorming.

Phases of Lean Coffee

  1. Theme Selection (Optional): The host may set a broad theme to focus the conversation, or leave it open. It is announced at the start so participants can shape their topics around it.
  2. Topic Generation: Each participant writes the topics they want to discuss on sticky notes, one per note, in a few silent minutes. The facilitator keeps this quick and encourages short, clear titles.
  3. Kanban Board Setup (To Do, Doing, Done, Actions): The facilitator draws or opens a simple board with To Do, Doing and Done columns, often with a space for actions. All new topics go into To Do.
  4. Topic Pitching/Introduction: Each person reads out their topics in a sentence or two so everyone understands them before voting. The facilitator keeps pitches brief and may cluster duplicates.
  5. Democratic Voting (Dot Voting): Everyone gets a small number of votes, usually two or three dots, to place on the topics they most want to discuss. Votes can be combined on one topic.
  6. Backlog Prioritization: The facilitator orders the To Do column by number of votes, so the most popular topic is discussed first. The group now has an agenda it built itself.
  7. Timeboxed Discussion: The top topic moves to Doing and the person who proposed it opens the discussion. The group talks for a fixed timebox, often five to eight minutes, tracked visibly by the facilitator.
  8. Roman Voting (Continuance Decision): When time runs out, everyone votes thumbs up to continue, sideways for neutral, or down to move on. If the majority wants more, a shorter extra timebox is added; otherwise the topic closes.
  9. Topic Transition: The finished topic moves to Done, any takeaways are noted, and the next highest-voted topic moves into Doing. The cycle repeats until the meeting time ends.
  10. Wrap-up and Action Item Capture: In the last minutes, the group reviews what was discussed, records action items with owners, and may reflect briefly on the format. Unused topics can carry over to a next session.

Key principles

  • Democratic agenda-building
  • Visual management via Kanban
  • Strict timeboxing for focus
  • Participant-led prioritization
  • Just-in-time discussion

Best for

  • Social and peer-to-peer learning
  • Collaborative problem solving
  • Agile retrospectives
  • Community building

Considerations

  • Requires a facilitator to maintain the cadence and manage the timer
  • Group size should ideally be limited to 5-10 people per table for optimal participation
  • The quality of the session is dependent on the participants' willingness to contribute topics
