Liberating Structures
Min Specs
Specify only the minimum required do’s and don’ts for achieving a purpose. Min Specs helps groups strip away unnecessary constraints, habits, and assumptions so they can focus on what truly matters.
Min Specs
What is made possible - What it unlocks
Min Specs makes it possible to clarify the non-negotiables for any initiative, team, or project. By separating the “musts” from the implicit “nice-to-haves,” groups often discover that many barriers are self-imposed. The structure removes clutter, reduces over-engineering, exposes false constraints, and reveals the essential conditions that enable progress.
When to use it
- When teams feel overwhelmed by too many procedures or expectations
- Before or after strategic planning to clarify what truly matters
- To shift from big ambitions to concrete, actionable guardrails
- When a project lacks clarity or keeps drifting
- To simplify collaboration in cross-functional teams
- To reduce complexity in processes, habits, or routines
- When a group struggles with inconsistent priorities
🛠️ The five design elements of Min Specs
Each Liberating Structure consists of five simple design elements to make participation possible for everyone. By shaping these elements with care, you move beyond rigid control or chaos and create space for people to contribute, listen, and co-create.
- 1. The Invitation
- 2. Setup & Materials
- 3. Participation Flow
- 4. Group Configuration
- 5. Sequence & Timing
How you frame the purpose or question that sets the focus and energy of the group.
Invite participants to identify the absolute minimum specifications needed for success:
“What must we do — and what must we not do — in order to succeed?”
The arrangement of space and which tools or resources are needed to support interaction.
- Paper, cards, or shared digital board
- Two visible columns: Must Do and Must Not Do
- Space for individuals, pairs, and small group conversations
- Optional: good examples of Min Specs from earlier work
Who gets a voice and how everyone is actively included in the process.
- Everyone contributes possible specs individually.
- Then refines and reduces them collaboratively.
- All voices share ownership.
How people are arranged (alone, small groups, or all together) and how this shifts during the activity.
Individuals → pairs → small groups (4–7) → whole group (for convergence).
The step-by-step flow of the activity and the time given to each step to keep energy and focus.
- Start with a clear purpose.
- Generate the list of all must-do and must-not-do activities (Max Specs), at first alone for 1 minute then consolidate and expand in the small group for five minutes. Make list as complete as possible in a short time. (6 min)
- Each small group tests each spec on its Max Spec list against the purpose statement. If the spec can be violated and the purpose still achieved, the spec is dropped from the list. (15 min)
- Do a second round if needed. (15 min)
- Compare across small groups and consolidate to the shortest list. (15 min)

Step 1 – State Your Purpose: (3 min)
Write down your purpose or goal clearly and specifically. What are you trying to achieve? What does success look like? This purpose statement is your test. Everything else will be measured against it.
Step 2 – Generate Max Specs: (10 min)
Brainstorm ALL possible must-do and must-not-do activities, rules, or conditions to achieve your purpose. Don’t filter yet—write down everything you think might be necessary. Include habits, behaviors, constraints, boundaries, resources, and standards. One item per line. Aim for 15-25 items total across both columns. Be as complete as possible in a short time.
Step 3 – First Testing Round: (7-10 min)
Take each item on your Max Spec list one by one. For each spec, ask yourself: “If I violated this specification, could I still achieve my purpose?” If the answer is YES (you could still succeed without it), cross it off the list. Only keep specs where violating them would make success impossible. Be ruthless.
Step 4 – Second Testing Round: (5-10 min)
Review your remaining specs again. You probably still have items that aren’t truly essential. For each remaining spec, ask: “Is this absolutely non-negotiable? Or is it just my preference or habit?” Don’t protect sacred cows or confuse preferences with requirements. Test again: “Can this be violated and the purpose still achieved?” Drop anything that fails the test. Push yourself to reduce the list further.
Step 5 – Finalize Your Min Specs: (5 min)
Write out your final, shortest list of Min Specs. You should have roughly 3-7 items total (combining Must Do and Must Not Do). Number them. Make sure each one is concrete, observable, and genuinely essential. If your list is longer than 7 items, test one more time.
Step 6 – Integration: (3-5 min)
Reflect on what you discovered: What surprised you about what’s truly essential versus what you thought was necessary? How does this clarity change what you’ll focus on or let go of? What becomes easier when you know your Min Specs?

🧠 Why it works
Liberating Structures are not magic tricks—they work because they tap into how people naturally think, connect, and collaborate. Each structure is carefully designed to unlock participation, spark creativity, and build trust, using principles grounded in social science and human interaction.

Constraint Clarity
Clarifying the minimum constraints prevents over-structuring, allowing adaptive behavior while still providing enough direction for coherence.
Cognitive Reduction
The process reduces mental overload by distinguishing essential rules from noise — freeing energy for creativity and execution.
Collective Prioritization
Groups often operate from unspoken assumptions; surfacing them exposes how the system currently organizes itself and what truly drives outcomes.
Actionability Boost
Concrete, minimal rules lower the threshold for action. People act faster and more consistently when expectations are simple and memorable.
Riffs and Variations
Start with creative constraints to learn this structure and then... go liberate yourself and try some variations.
- Reverse Min Specs: Start with Must Not Do to uncover hidden constraints.
- Extreme Reduction: Challenge groups to reduce their list to only 1–2 Min Specs.
- Role-based Specs: Create Min Specs from different roles (team lead, frontline, customer).
- Process-specific Specs: Use Min Specs for onboarding, meetings, feedback, experimentation.
- Prototype & Test: Apply Min Specs for one week, then refine.
- “Future state” Min Specs: Identify rules needed for the organization you want to become.
Tips
Lessons learned from other facilitators.
- Aim for essential, not comprehensive. Focus on what is absolutely required — nothing more.
- Make everything concrete and observable. Specs must describe real behaviors or boundaries.
- Challenge every item: “Is this truly essential?”. Push groups to reduce, not expand.
- Include Must Not Do’s. These often liberate more energy than Must Do’s.
- Test with real scenarios. “Can we act with these specs tomorrow?”
- Encourage dissent. Disagreement sharpens clarity and avoids blind spots.
Traps
Don't make the same mistakes.
- Don’t create a long list. More specs = more confusion and less action.
- Don’t include vague abstractions. “Be collaborative” is not a Min Spec — specific behavior is.
- Don’t protect sacred cows. Nothing is safe unless it’s truly essential.
- Don’t confuse preferences with requirements. Nice ideas are not Min Specs.
- Don’t let hierarchy decide. Everyone contributes; essential constraints come from the work, not authority.
Try it with…
The real power of Liberating Structures emerges when you combine them into "strings." Link different structures together to build on insights and create more powerful results. Here are some nice combinations:
- Nine Whys: to ensure your Min Specs align with deeper purpose
- TRIZ: to stop behaviors that contradict the Min Specs
- 1-2-4-All: to quickly generate and refine possible specs
- Purpose-to-Practice: to define the “Rules” element of P2P
- Ecocycle Planning: to identify which specs belong to which developmental phase
- Wicked Questions: to capture tensions that Min Specs must honor
