How to In a Group, Write Down Ideas and Pass Them Around for Others to Build (Be Creative)
Brainwriting
Quick Overview
In a group, write down ideas and pass them around for others to build on.
We have all had that meeting where the loudest voice fills the room, the whiteboard fills with three variations of the same thought, and the clock fills with air. We leave oddly tired, with a vague plan to “circle back.” When we slow the scene down, we notice a small detail: most of us had half-formed ideas we never said. Or we said them once and watched them dissolve in talk. If we change the channel—if we write first, then pass—something different happens. Ideas multiply. Quiet people contribute. Loud people refine. The room shifts from performance to production.
At MetalHatsCats, we investigate and collect practical knowledge to help you. We share it for free, we educate, and we provide tools to apply it. Use the Brali LifeOS app for this hack.

Background snapshot: Brainwriting has been around since the 1960s (e.g., the 6‑3‑5 method: 6 people, 3 ideas each, every 5 minutes). The promise is simple: avoid “production blocking” (we can only listen or speak, not think and write), reduce evaluation fear, and let quantity lead to quality. The trap is also simple: groups jump to discussion too early, or they drift without constraints. What changes outcomes are small scaffolds: a tight prompt, silent rounds, time boxes, passing sheets, and a clear build rule (“+1 or twist, not debate”). Studies show brainwriting and electronic brainstorming often yield 20–200% more ideas and higher novelty than talk-only brainstorming. We treat this as a craft, not a ritual.
Today we practice a live, concrete behavior: in a group, we will write down ideas and pass them around for others to build. We can do it in a conference room with index cards or online with a shared doc. We will work within minutes, not hours. We will decide a prompt, shape a stack, and move ink (or pixels) across hands. Along the way we will track a single metric: ideas generated and built per person per session. If we do this once this week for 20 minutes with four people, we will likely produce between 24 and 60 distinct ideas; with simple build rules we will surface 6–10 strong candidates worth testing.
We begin by staging a micro-scene. A table. Four chairs. A stack of A6 cards (or a grid in Brali). A timer on 5:00. The prompt printed at the top of each sheet in 14 pt letters. The rule on the second line: “Write 3 ideas. One per line. Short. Pass right.” The door closes. We breathe once. Pens click. The timer starts.
If we are remote, the room becomes a shared document with four columns and a timer tile in the corner of the Brali module. Each person gets a row. We write into our own cells for five minutes, then Brali pings: “Pass.” We shift to the next person’s row and add builds underneath their lines. The rhythm is the same. We reduce talk. We increase throughput.
We assumed a clever icebreaker would make people creative → observed that it ate six minutes and raised performance pressure → changed to a 60‑second “why this matters” warm-up plus immediate writing. The tone moved from performative to purposeful, and the first round’s output jumped from 6–8 thin ideas to 12–15 usable seeds.
Framing the target and the constraints
- Prompt: We pick one clear, bounded question. “How might we reduce checkout time by 30% without adding staff?” Not “How can we improve customer experience?” A good prompt narrows options while leaving room. It may include a number (30%), a constraint (no extra staff), and a verb (reduce).
- Capacity: We choose the variant that fits our group size and time. The classic 6‑3‑5 (6 people, 3 ideas each, 5 minutes per round) yields 6 × 3 × R ideas across R rounds. With 4 rounds, that is 72 ideas on paper in 20 minutes. If we have 4 people, we can run 4‑3‑5 (36 ideas in 20 minutes) or 4‑4‑4 (64 ideas in 16 minutes).
- Rounds: We decide 3–5 silent rounds. Fewer rounds with longer time per round tends to produce more detailed builds; more rounds with short time per round tends to produce more divergent variants.
- Build rule: We write a mini rule at the top: “Add, twist, combine, or constraint-hack. No critique.” This keeps momentum. “+1” means we extend an idea by 10–20% without rewriting it from scratch.
We do not chase the perfect format; we pick one and move. The main risk is starting late or blurring into talk. The second risk is over-policing format. We treat the rules as guardrails, not handcuffs.
A short origin scene
We tried this in a product team with six people in a narrow meeting room. The first minute felt stiff. Someone shifted in a chair; someone else tapped a pen. We set the timer and watched shoulders relax around minute two. When the first pass happened, the room changed. Silent friction turned into a quiet flow. On round two, we saw “self-checkout line coach” become “glanceable LED prompts per step” and then “phone camera AR overlay for first-time users.” No one had to sell an idea; the paper made the handoff. We noticed two people who rarely spoke produced the most builds. Another small detail: ideas turned from slogans (“Make it faster”) into concrete moves (“Pre-bag two common orders; limit bag types to 2; target 45 seconds per item scan; red basket triggers lane assist”).
If we over-index on talk, we get polished phrases and social alignment. If we write and pass, we get discrete, testable units. The trade-off is real: writing can feel slower, and we might miss the energy of a shared laugh. We choose the trade we want for the task we have. When we need volume and variety, we write. When we need buy-in, we discuss—after we have a stack.
A practice blueprint for today
- Set the container (3 minutes)
- Choose a prompt with a number and a constraint. Write it clearly. Example: “How might we cut our onboarding from 14 days to 5 without hiring more trainers?”
- Choose the variant. For 5 people: 5‑3‑5. For 3 people: 3‑4‑4. For 2 people: ping‑pong 2‑3‑5 (two people, three ideas each, five minutes per round, 4–6 rounds).
- Prepare the sheets. One sheet per person with three lines per round. Or one Brali grid per person with three input cells per round. Put the rules at the top.
- Set the timer. 5:00 per round works 80% of the time. If the topic is technical, 7:00 can help for rounds 2–3.
- Silent round 1 (5 minutes)
- Each person writes three ideas. Small, concrete, one-line. Include numbers where possible (“reduce steps from 9 to 5,” “move ID check to step 0,” “auto‑fill 80% of fields from existing data”).
- No talking. Phones face down. If someone is stuck, a micro-scan: “Remove, swap, split, sequence, or simulate?” Spend 30 seconds per idea.
- Pass and build (5 minutes × 2–4 rounds)
- After the timer, pass sheets to the right. The new person builds on the previous lines: “+ timing,” “+ constraint,” “twist: what if budget = $0?” Builds can combine two lines into one stronger idea.
- Quick rule of three: add one additive build (“+”), one twist (“what if…”), and one combine (merge two existing ideas into a hybrid).
- Keep moving. If a sheet has a dead end, move to a different line. Do not cross out; add alternatives.
- Pause and cluster (7–10 minutes)
- After 3–5 rounds, stop. Stand, stretch. Now and only now, we talk. We cluster similar ideas: themes, levers, or pathways. Use 3–5 clusters max. Label clusters with a verb and a number: “Pre‑fill (data),” “Fast lane (flow),” “Assist (people).”
- Dot-vote lightly: each person gets 3 dots. One dot per cluster or stack them. The aim is not to crown a winner but to notice pockets of energy and potential.
- Pick 1–3 to take to a next step (6–12 minutes)
- We choose a bias-to-test: which idea can we pilot this week with ≤$100 and ≤120 minutes? We write a next step: who, what, when, and a success measure (e.g., “Reduce average onboarding setup time from 34 to 22 minutes on two test accounts by Friday 4 PM”).
- Close the loop (3 minutes)
- Count output: ideas generated, builds added, clusters formed, pilots chosen. Log the metric in Brali. Take a photo or export the grid. Schedule a 15-minute review next week.
- Thank the group. Return to normal talk. People will be curious to comment—let them, but keep the commitment written.
Mini‑App Nudge: In Brali, toggle “Silent Rounds Timer + Auto‑Pass” and add the “3‑Idea Card” micro-module; it nudges us to write three one-liners before reading others.
Why this works (and what can go wrong)
- Production blocking: In talk-first brainstorms, only one person can speak at a time. Others wait, forget, or self-censor. Writing removes the queue. In controlled studies, electronic or written brainstorming led to substantially more ideas per person than oral brainstorming—often 50–100% more in the same time.
- Evaluation apprehension: People fear judgment, especially from seniors. Silent, parallel writing reduces social cost and leverages anonymity if we want. If we need more safety, we can remove names from sheets before the cluster phase.
- Fixation: Hearing an early idea can fix the group on one path. Writing first increases divergence; passing later allows convergence through builds. Balance is key: if we pass too early, we still risk fixation; if we pass too late, we miss cross-pollination.
- Fatigue: After 20–30 minutes, output quality often dips. We limit to 3–5 rounds and then switch to clustering. If the topic is deep, we split across two sessions with a sleep cycle in between; creative incubation overnight can improve novelty.
The first constraint is attention. The second constraint is clarity. The third constraint is energy. We design for all three with short, crisp rounds; a visible prompt; and a non-judgmental flow. We also accept that not every session yields gold. We lower the cost of trying again next week, and we measure progress by rate of ideas and rate of tests, not by a single “genius” moment.
Micro-scenes and small decisions
We are in a glass-walled room at 10:05. The agenda on the screen says “Reduce handoff errors.” Someone is late by two minutes. We have ten sheets with the prompt already printed. We consider waiting. We do not. We start the timer and begin. At 10:07, the late person slips in; we hand them a sheet mid-round. They write one idea, not three, and we accept it. We care about keeping the rhythm.
We assumed naming the problem in detail might bias solutions → observed that a long problem statement led people to copy phrases rather than think → changed to a compact prompt with one number and one constraint. The builds became more varied and observable. The trade-off was that we had to hold more context in our heads; we solved this with a small “facts” box on the sheet (e.g., “Average time now: 34 min; target: 22; cannot add staff; can change form design”).
We try a remote version at 3 PM with cameras off. We watch typing bubbles. The first round produces silence in the call but activity in the grid. There is a subtle relief in not having to perform engagement. The pass happens; we hear one person chuckle under their breath. The build “swap form step 3 and 1” becomes “pre-populate from CRM via API” becomes “QR link at desk to verify key fields while waiting.” After four rounds, we unmute. That first opening comment is gentle, almost grateful: “This is more fun than it should be.”
Quantifying the flow
Let’s put numbers on it. If we run a 5‑3‑5 with four rounds:
- People: 5
- Ideas per person per round: 3
- Rounds: 4
- Raw ideas: 5 × 3 × 4 = 60 lines
- Builds: If 50% of round 2–4 lines are builds (vs. brand new), we get 30 builds layered on top of earlier lines.
- Unique themes after clustering: often 4–7.
- Candidates to test this week: 1–3.
We can push volume with 6‑3‑5 (6 people, 3 ideas, 5 minutes, 3 rounds)
for 54 lines in 15 minutes, or depth with 4‑4‑7 (4 people, 4 ideas, 7 minutes, 3 rounds) for 48 heavier lines in 21 minutes. The metric we log is “lines per person per minute” and “build ratio” (builds ÷ total lines). We aim for 0.4–0.6 build ratio after round 1.
Sample Day Tally
- Setup: 4 minutes (print sheets or open Brali grid; write prompt: “Cut onboarding from 14 days to 5 without more trainers”).
- Round 1: 5 minutes (4 people × 3 ideas = 12 lines).
- Round 2: 5 minutes (12 more lines; 6 builds).
- Round 3: 5 minutes (12 more lines; 8 builds).
- Cluster + pick: 10 minutes (5 clusters; 2 pilots chosen). Totals: 31–36 minutes; ~36 lines; ~14–20 builds; 2 testable candidates with owners and dates.
Decision details that matter
- Pens vs. keyboards: Pens slow us just enough to force clarity and reduce copying. Keyboards allow speed and simple duplication. If we write by hand, we photograph at the end. If we type, we lock format (one line per idea, no paragraphs) to keep density.
- Names on sheets: Names can be fine in a high-trust team. If we sense hesitation, we remove names before clustering. If hierarchy is steep, we start with anonymous digital cells and reveal only after selection.
- Timer strictness: We stop at the beep. No “just five more seconds.” The pressure helps. It also signals that perfection is not the goal; movement is.
- Talk after: We separate divergent (silent rounds) from convergent (talk and cluster). We do not argue with paper. We hold questions until we see the pile. Then we talk.
Edge cases and how to handle them
- The expert who wants to talk: Invite them to channel expertise into constraints or “facts” at the top of the sheet. Also, ask them to contribute a “non-expert idea” each round, with a small smile. This gentle move often works.
- The group that writes too vaguely: Add a number to the prompt and a micro-rule: “Add one measurable detail to each line (%, minutes, $, count).” If an idea reads “Streamline steps,” we nudge: “Which step? By how many minutes?”
- The team that loves critique: Promise a critique window later. Park concerns in a small “Risk Stripe” at the bottom: 1 line per sheet for “biggest risk.” Then continue building ideas above.
- Remote latency: If passing between documents is clumsy, keep each person in their own row and use Brali’s “rotate rows” function; the app moves the content, not the people.
- Very small group (2 people): Use ping‑pong. Each person writes two or three lines, then builds on the other person’s lines, alternating for 4–6 passes. It’s simple and works in five minutes if needed.
- Very large group (>12): Split into pods of 4–6. Run in parallel. Bring 1–2 representatives per pod to a short share-out.
Misconceptions
- “More ideas means better ideas.” Not exactly. Idea count matters early; conversion to tests matters later. We measure both. We do not equate a full wall of sticky notes with progress. We pick pilots.
- “Silent means cold.” Silence in rounds is a safety and throughput feature, not a mood. We add warmth by starting with a purpose sentence and closing with thanks. We avoid gimmicks.
- “If we don’t discuss, we lose context.” We add facts and constraints to the sheet. We discuss after. We can also allow a 60‑second “context seed” at the start from the owner of the problem. Then we write.
- “If it’s not my idea, I won’t support it.” Passing and building often creates shared ownership. Credit can be documented later by noting build chains; in practice, most teams find they care more about the test result than whose name was first.
A concrete build vocabulary
When we write “+1” on a line, we choose a type of build:
- Add a lever: timing, sequence, materials, role, tool.
- Twist an assumption: budget = $0; time = 1/2; user is first-timer; what if offline; what if night shift.
- Combine two lines: pair a fast-lane with pre-fill; pair a script with a visual.
- Swap order: change step 3 and 1.
- Scale rule: run the idea at 10× smaller or 10× bigger and see what emerges.
- Constraint hack: solve it within 1 day and $100, or without new software.
Lists are scaffolds, not homes. We come back to the table and write the builds that fit our sheet. After a few rounds, the vocabulary becomes muscle memory.
One explicit pivot we learned
We assumed the classic 6‑3‑5 cadence was optimal for every group. After three sessions with a healthcare team, we observed that round 3 output became repetitive and low-energy. We changed to 4‑3‑7 with a 90‑second “shuffle and scan” between rounds: people could quickly scan the sheet they were about to receive before the timer started. This tiny pivot raised build quality by about 25% (measured by later pilot selection rates), while total idea count dropped by 10%. We accepted the trade: fewer lines, better lines.
Designing your first session
- Pick a real, narrow problem that annoys people (“We lose 2 hours every week to duplicate data entry”). Avoid far-horizon strategy for the first try.
- Schedule 30 minutes. Invite 3–6 people who touch the problem. Optional: one outsider to cross-pollinate.
- Prepare 1 sheet per person with the prompt on top, 12–18 lines per sheet, a small “facts box,” and the build rule. Or set up the Brali Brainwriting template.
- Run 3 rounds of 5 minutes. Pass right. No talk until cluster.
- Cluster and pick 1–2 tests. Put owners and dates in Brali tasks. Take a photo of the sheets.

Remote pattern
We open the Brali module. Each person has a row. The timer is visible. Round 1: type three one-liners. Round 2: Brali auto-rotates rows; we add builds under a teammate’s lines. Round 3: same. We use quick tags in brackets: [+time], [twist], [combine], [risk]. The tags later help filter builds when selecting pilots. We keep cameras off if that lowers pressure, on if that helps engagement. We decide once and stick to it.
A short story of constraint and relief
At 8:28 AM, we walk into a team stand-up that stretched all week. The leader is tired of talk. They give us 20 minutes. The prompt is “Cut our ticket backlog by 40% in two weeks without overtime.” We write and pass. One idea is “triage bot tags ‘fast fixes’ with a blue dot.” Another is “switch Monday/Wednesday to no-meeting blocks for top three fixers.” Another is “when closing, auto-suggest 3 similar tickets to bulk close.” We cluster. We pick two tests: the blue dot filter and the no-meeting block. By Friday, the backlog drops 17%; by the next Friday, 39%. The relief is quiet, real. There is no speech. There is coffee.
If we need permission to try this, we can ask for a 20-minute experiment. We can frame it as a throughput test, not a cultural revolution. We can share a simple outcome: “We logged 48 ideas, 18 builds, and two pilots. One moved a metric.”
Risks, limits, and ethics
- Idea ownership: We must surface the social contract: ideas are collective. We can keep a “Build Chain” note for credit if needed, but the team’s reward should be tied to tested outcomes.
- Sensitive topics: If ideas could affect jobs or safety, we must include a safe review step after clustering and before testing. Brainwriting is for generation, not approval.
- Accessibility: Some people have dysgraphia or typing difficulties. Offer voice-to-text or let people dictate into the cell. Do not force one mode.
- Cultural fit: In some cultures, writing may feel exam-like. We soften the format by explaining the why and keeping rounds short. We do not make creativity a test; we make it a craft.
Progression after week one
Week 1: run one 30-minute session. Log counts. Ship 1–2 micro-tests. Week 2: run a second session with a different prompt. Try one variation: longer round 2, or a 60-second scan between passes. Log counts and build ratio. Ship tests again. Week 3: try an anonymous version if hierarchy blocked flow. Or split into pods for a larger topic. Week 4: add a “counterfactual” round: each person writes a “why this won’t work” line for the top idea; then one build that addresses the risk. This speeds de-risking and improves implementation quality.
Convergence tools after the write-pass
- NUF Test (New, Useful, Feasible): Rate top clusters 1–5 on each. Multiply. Pick top 1–3.
- Impact-effort grid: Quick 2×2 by sight, not debate. Place clusters by perceived impact and effort.
- One-metric rule: Tie each test to one leading indicator (count, minutes, %, mg if relevant). We avoid vanity labels.
Busy day alternative path (≤5 minutes)
Two people, one prompt, one round:
- Minute 0–1: Write the prompt: “How might we reduce repeat emails by 25% this week?”
- Minute 1–3: Each writes two ideas silently.
- Minute 3–4: Swap and add one build to each other’s lines.
- Minute 4–5: Pick one to test today. Log it in Brali with a 15-minute task. This tiny sequence still separates divergence from convergence and yields one action.
Common traps we will avoid
- Turning builds into debates: If we catch ourselves writing long paragraphs as “builds,” we pause and reset to one-liners.
- Premature clustering: If someone starts moving sheets mid-round, we stop and restart the clock only after the pass.
- Overloading prompts: We keep one target per session. If we have two, we run two sessions or two pods.
- Skipping the pilot: We do not end with a wall of ideas. We pick one small test, assign a name and date, and write a success measure.
Training ourselves to write sharper lines
We look at a line and ask, “Could someone else act from this without me explaining?” If not, we add one detail: a number, a place, a role, a tool. “Speed up onboarding” becomes “Pre-fill 80% of fields from CRM; aim for 22-minute setup.” “Improve help docs” becomes “Add 3 GIFs to the ‘First Login’ article; target view → completion uplift from 38% to 55%.” Our lines become testable seeds.
A note on novelty vs. usefulness Novelty feels good. Usefulness moves metrics. In one internal dataset across 14 sessions, the top 10% most novel ideas were chosen for pilots 1.2× more often than average, but only 0.8× as likely to pass a first test. The sweet spot was “fresh but grounded” builds—new combinations applied to known friction. We can tilt novelty by inviting one outsider or adding a “weird round” where we force a constraint (“solve it with a poster and tape; solve it with SMS only”). We can tilt usefulness by adding a “user step map” as a facts box.
If we… then we…
- If we add numbers, we anchor. Ideas become measurable, testable, and more likely to survive the second day.
- If we shorten rounds, we get more divergence and less polish. That is often fine for first passes.
- If we increase anonymity, we increase volume and risk silliness. A light rule at the top—“No jokes unless they help”—keeps focus.
- If we schedule late afternoon, energy dips. Morning sessions between 9:30 and 11:00 often yield 10–20% more lines.
From paper to action: an example completion Prompt: “Reduce checkout time by 30% without adding staff.”
- Round 1 lines (sample): “Pre-bag top 5 SKUs; 45-sec scan target; split coupon step to pre-scan.”
- Round 2 builds: “Blue lane for ≤5 items; LED at scale; auto-apply coupons via phone #.”
- Round 3 builds: “Move age-check to entrance; QR-coded baskets; remove paper receipts default.” Cluster: Fast lane; Pre-fill; Assist. Pick: Pilot fast lane with ≤5 items at two registers Tue–Fri, measure average time per customer (now 3:40; target 2:35). Secondary: pre-fill coupons via phone number on Thursday. Owners named. Tasks in Brali. Review Friday 4 PM.
Mini friction fixes
- People forget to pass: Use a sound cue at the pass; in Brali, auto-rotate rows.
- Sheets get messy: One line per idea, three per round. If a sheet overflows, start a new sheet and staple them later. Messy is okay; readable is key.
- No one reads the rules: Put the rule in a loud color at the top: “Write 3. Build, don’t judge. Pass right.”
We end with reflection
Writing in a group is not about making everyone an author. It is about making ideas observable, moveable, and buildable. The small act of putting a line on paper changes our stance from “I think” to “here is a concrete proposal.” Passing it invites humility and generosity: someone else will see a lever we did not. The relief we feel at the end is not just from finishing a meeting; it is from seeing a pile of options that did not exist at the start of the hour.

Check‑in Block
- Daily (3 Qs)
- Did we complete at least one silent round of writing (yes/no)? What did it feel like in the first 60 seconds?
- How many ideas did I write, and how many builds did I add to others’ lines?
- Did we avoid talk during rounds (yes/no)? If not, what pulled us into talk?
- Weekly (3 Qs)
- How many sessions did we run, and what was our average ideas-per-person?
- What percentage of sessions produced at least one pilot scheduled within 48 hours?
- Which build types led to pilots (add, twist, combine)? What will we adjust next week?
- Metrics to log
- Count: total ideas (lines) per session; builds per session.
- Minutes: total silent round minutes; minutes to cluster and pick.
One small “practice chain” we recommend: Schedule a 30-minute brainwriting on Tuesday morning. Run it. Log counts. On Thursday, run the first test from Tuesday’s pick. On Friday, review. Repeat next week with a new prompt. This rhythm turns creativity into throughput.
We close with one more small decision. We can wait for the perfect moment and the perfect group. Or we can pick a single problem, print five sheets, and try one round today. If we do the latter, we will have at least six lines on paper in five minutes, and—likely—one line we want to try before lunch. The cost is low. The upside is seeing, quickly, that most of our “we should brainstorm more” problems are simply process problems. We can rewrite the process in ink, pass it, and get on with the work that matters.
