Volume Generation

Three traditions for producing many ideas fast:

• Crazy 8s — Google Ventures Sprint method. Codified in Sprint (Knapp et al., 2016).
• Brainwriting 6-3-5 — Bernd Rohrbach, 1968. German design-method literature.
• James Webb Young — A Technique for Producing Ideas (1940). 60-page book; canonical advertising-copywriter manual.

When to use

• Time pressure with a generative goal
• Group ideation (brainwriting reliably outperforms verbal brainstorming)
• Quantity-before-quality phase
• You need to produce many to find the few good ones

Don't use when

• You don't have material yet (Young's stage 1: gather first)
• The right answer is rare and you'll know it when you see it (volume can paradoxically miss it)
• Solo with no time pressure (use deliberative methods instead)

Crazy 8s

1. Fold a sheet into 8 panels (or use a printed grid).
2. Set a timer for 8 minutes.
3. Sketch one idea per panel — eight ideas, one minute each.
4. Sketch, don't write. Visual format forces concretization.
5. After timer: pick 1–3 strongest panels.
6. Group share.

The first 4–5 panels are usually slop; the last 3–4 are where surprises live (the easy ideas have been exhausted).

Brainwriting 6-3-5

Outperforms verbal brainstorming consistently in academic creativity research (Diehl & Stroebe, 1987 + many replications). Verbal brainstorming has well-documented production blocking, evaluation apprehension, and social loafing. Brainwriting eliminates all three.

1. 6 participants, each with a sheet.
2. Each writes 3 ideas in 5 minutes, in a row at the top.
3. Papers rotate. Each participant now sees the previous 3 ideas; writes 3 new ones — building or fresh.
4. Repeat until each sheet has been seen by all 6.
5. Result: 6 × 6 × 3 = 108 ideas in 30 minutes.

James Webb Young — 5 stages

Honest about the temporal structure of idea formation. Most methods assume ideas come on demand; Young's account is that they often don't, and the work is upstream.

1. Gather material. Specific and general material. Most idea-generators fail here. "Just one more idea about the product, just one more bit of factual material — many a time these have made all the difference."
2. Mentally digest. Turn the material over. Make tentative partial connections. Don't reach for a final idea.
3. Drop it. Stop working. Sleep, walk, watch a movie. The unconscious works on it.
4. The idea arrives. Often during a shower or walk. "It will come to you when you are least expecting it."
5. Shape and develop. The arriving idea is half-formed. Subject it to actual scrutiny.

The drop stage is non-negotiable. Compressing it back into 1→2→4 produces incomplete ideas.

When to use which

Time available	Group size	Use
8 minutes	Solo	Crazy 8s
8 minutes	Group	Crazy 8s + share
30 minutes	Solo	Crazy 8s + 22 min elaboration
30 minutes	Group of 4–8	Brainwriting 6-3-5
1 hour	Group	Brainwriting + 30 min affinity diagram
1 day	Solo	Young stages 1–3
1 week	Solo or small group	Full Young 5 stages

Anti-slop notes

• Volume of equal quality is not volume. Eight panels of identical structure is one idea drawn eight times. Force divergence by applying different generative methods to different panels.
• Don't pad to round numbers. If only 5 of the 8 panels produced anything, surface 5.
• Surface 1–3 to the user, not all 8 / all 108.
• Don't conflate volume with depth. Volume is breadth-first; depth comes later with elaboration methods.
• Respect Young's drop stage. Rushing from gather → idea in one session usually fails.
