Liberating Structures: 6 formats you can use today

Liberating Structures are 43 ways to organise a conversation, developed by Henri Lipmanowicz and Keith McCandless. They don't change what you discuss but who gets to speak — and in practice that turns out to make the bigger difference.

Below: what they are, how to tell which one you need, and 6 structures you can run here straight away.

What are Liberating Structures?

Most meetings run on five formats: someone presents, someone leads a discussion, there's a status round, there's a brainstorm, or people talk in small groups with no further rules. All five share one problem — they hand most of the speaking time to whoever is fastest or most senior.

Lipmanowicz and McCandless collected 33 alternatives and described them in The Surprising Power of Liberating Structures (2013). The collection has since grown to 43: a second generation was added, and in 2026 Keith McCandless and Nancy White published a fieldbook. Each structure is short, needs little material, and needs no certification — they are published under a Creative Commons licence (CC BY-SA 4.0) that explicitly allows using, translating and adapting them, commercially too.

What they share is that they fix how turns are distributed in advance. Not as a courtesy rule but as part of the format itself. Skip the minute of silence and you get the first speaker's idea; build it in and you get as many ideas as there are people.

What a structure is made of

Every Liberating Structure specifies five things. If you're adapting a format yourself, these are the dials:

  1. The invitation — the exact question you ask. Often the only thing you need to prepare.
  2. Space and materials — chairs in a circle, a wall for sticky notes, or nothing at all.
  3. How participation is distributed — everyone equally, or deliberately not.
  4. How groups are configured — alone, in pairs, in fours, plenary.
  5. The sequence and time per step — this is what makes a structure a structure.

Those last two are also where it goes wrong in practice. A format whose phases you don't time slides back into an ordinary discussion within ten minutes.

Which one to pick

Group size and duration are those of the structure as it runs here — you set the time per step yourself when preparing.

The structures up close

1-2-4-All

The most used, and for good reason: it fits anywhere and takes twenty to thirty-five minutes. Everyone thinks alone first, shares in pairs, then in fours, then plenary. The silence at the start is what gives the format its value — without that minute, the group discusses whatever the first person happened to say.

The number of phases doesn't grow with the group, so the format keeps working at a hundred people; the version here is set up for a class or team of up to about thirty, because the shared clustering at the end does scale with the number of groups.

Trio advice (Troika Consulting)

In threes, one person puts forward a real question. The other two first ask clarifying questions, then think out loud as if the person weren't there — they turn their chair around and only listen.

Turning around is the whole trick. As long as they're in the conversation they defend; the moment they only listen, they hear what's actually being said. One case takes about fifteen minutes, so after three cases — three quarters of an hour — everyone has had a turn.

Nine Whys

In pairs, one person asks "why is that important to you?" nine times, each time about the previous answer. Around the third or fourth time the polite answer usually runs out and something more honest arrives. Then the roles swap, and at the end each pair says in one sentence which purpose surfaced: what comes back in several pairs is the shared purpose.

Useful at the start of an initiative, when a group seems to agree on what should happen but not on why. Ten to twenty minutes, and it needs no materials.

The worst plan (Making Space with TRIZ)

You ask the group the opposite question: how do we guarantee this fails? That produces a list everyone laughs at — until you ask which items on it we're already doing.

The inversion works because it removes the shame. Naming something that isn't going well is hard; writing it as a joke first and then pointing at it is much less so.

Conversation Café

Four to eight people, one object passed around, four rounds. Whoever holds the object speaks; the rest listen. No decision at the end, but understanding.

Meant for topics too complex or too loaded to solve on the spot. It takes half an hour to three quarters. The first round and the closing round carry the structure: without the first, the quickest speakers take over; without the closing round, the conversation stops because time is up. When time is short, shorten the second round first and the free dialogue last.

World Café

Several tables, each with its own theme on the same question. After every round participants move to a different table while a host stays put and summarises what's been said — or the sheet on the table keeps it. At the end you harvest the themes.

Strictly speaking this isn't a Liberating Structure but a method in its own right by Juanita Brown and David Isaacs, older than the collection. It's here because it does the same job and gets named in the same breath.

Where to start

With 1-2-4-All. Not because it's the best, but because it asks the least: one question, twenty to thirty-five minutes, almost no materials, and it fits inside a meeting you already had scheduled.

If that works, Trio advice is the logical second — it carries the biggest behaviour change, because the person with the question has to stay silent while others talk about them.

Save Conversation Café and World Café for later. They're not harder, but they need 30 to 90 minutes, and that's easier to get once the group has seen one of these formats produce something.

What goes wrong

  • Phase timings get abandoned. By far the most common failure. A phase that overruns always overruns in favour of whoever talks longest — exactly what the structure was there to prevent.
  • The facilitator joins in. Contributing to a pair or a trio feels helpful and steers the result. Walking around and listening is enough.
  • The question is too broad. "How can we collaborate better?" produces fifty ideas you can't cluster. "What's stopping us from delivering on time?" produces ten you can act on.
  • There's no follow-through. A group that gathers ideas twice with nothing happening won't play along the third time. Schedule clustering and prioritising in the same session — in 1-2-4-All they are already the fourth and fifth step.
  • The format gets picked before the question exists. Work out what you need first, then find the structure. The other way round you pick the one you enjoy most.

Frequently asked questions

Are Liberating Structures free to use?

Yes. They are published under Creative Commons BY-SA 4.0: you may use, translate and adapt them, commercially too, and no certification is needed to use them or teach them to others. The licence asks two things back: credit the creators, and if you publish an adaptation, share it on the same terms.

How many are there?

The original collection has 33; the menu now lists 43, with a second generation of structures added. On top of that there are variants developed by users themselves.

Do they work in a classroom?

Yes, though they were designed for teams and organisations. 1-2-4-All and The worst plan work unadapted in secondary and higher education; Conversation Café needs a group already used to listening.

Do they work online?

Most do, provided you have breakout rooms. 1-2-4-All and Trio advice are the easiest online; World Café is the hardest, because moving between tables is the whole point.

How is this different from ordinary group formats?

Mainly that the distribution of turns is part of the format rather than dependent on the facilitator's good intentions.
