Protocol
Alternate private generation with shared idea review
Use the group as input, then give people room to recombine it.
When it fits
- Individual ideation has stalled, but continuous group discussion is producing repetition rather than novelty.
When to avoid it
- More rounds can create fatigue. Use novelty of additions, not a ritual number of rounds, as the stop condition.
Why it matters
Run a short private generation round, expose the shared idea pool, then return to private generation with the instruction to extend, combine or contradict what appeared. Repeat only while the next round adds distinct options.
Steps
- Private round
- Shared review without voting
- Second private round that builds or diverges
- Stop when distinct additions collapse
An example
After reading ten product ideas, each person privately produces three combinations or counter-proposals before the group discusses selection.
Check your result
Later rounds add genuinely different options rather than paraphrases of the first pool.
Keep this limit in mind
- More rounds can create fatigue. Use novelty of additions, not a ritual number of rounds, as the stop condition.

Supports
Brainwriting is a written group ideation method that can produce different creative-process outcomes from synchronous verbal or electronic brainstorming.
Performance depends on task, sequence, medium and group design; no universal superiority claim is made.
