The scope and purpose of Solo Brainstorming are stated as a concrete question.
Solo Brainstorming
A practical method guide: clarify prerequisites and materials, understand the complete process, and look up outputs, pitfalls, and stop criteria.
Prerequisite
What needs to be finished first
focused ideation prompt, research snapshot, submission format and deadline and domain decision makers are available.
Preparation
What needs to be ready before start
focused ideation prompt, research snapshot, submission format and deadline, shared workspace, source links, and decision log.
Prompt owner · individual contributors · later facilitator
Collect focused ideation prompt, research snapshot, submission format and deadline in advance and mark open assumptions.
20–40 minutes plus synthesis
Prepare individual idea sprints with stimulus shifts and anonymised consolidation visibly and calibrate assessment terms before starting.
Core question
The one question this method answers
Which solution options can each person develop independently before collective synthesis?
Flow
Phases with goal, actions, output and pitfall
Solo brainstorming uses a clear prompt, short sprints, and deliberate perspective shifts. A later group sees all ideas anonymised and separates author status from content.
independent idea pack
Fictional worked example
individual idea sprints with stimulus shifts and anonymised consolidation as a precise working structure with a fictional example.
Prompt
Problem · user · constraint
Explain import mismatch without jargon.
Sprint idea
Stimulus · mechanism · sketch
Support perspective: repairable diff.
Assumption
Expectation · uncertainty
Users understand row comparison.
Synthesis
Cluster · contrast · test
Preview versus diff in usability test.
The example demonstrates the domain logic of Solo Brainstorming; worksheets remain blank.

Goal
Produce solo brief so the core question “Which solution options can each person develop independently before collective synthesis?” can be answered with stronger support.
Inputs for this step
- focused ideation prompt
- research snapshot
- submission format and deadline
Actions
- Provide problem, user, evidence, and no-gos compactly.
- Record source, rationale, and open uncertainty directly in solo brief.
Output
solo brief
solo brief · source · uncertainty · next decision
Quality check
Can the prompt be used without clarification?
Pitfall
The first idea dominates every sprint or later evaluation follows the author's authority. Introduce a new constraint or perspective prompt and anonymise submissions before synthesis.
Timing: 10–20 minutes

Goal
Produce idea set so the core question “Which solution options can each person develop independently before collective synthesis?” can be answered with stronger support.
Inputs for this step
- solo brief
- research snapshot
- submission format and deadline
Actions
- Run three short rounds with changing stimuli.
- Record source, rationale, and open uncertainty directly in idea set.
Output
idea set
idea set · source · uncertainty · next decision
Quality check
Do mechanisms differ rather than just surfaces?
Pitfall
The first idea dominates every sprint or later evaluation follows the author's authority. Introduce a new constraint or perspective prompt and anonymise submissions before synthesis.
Timing: 10–20 minutes

Goal
Produce anonymous pack so the core question “Which solution options can each person develop independently before collective synthesis?” can be answered with stronger support.
Inputs for this step
- idea set
- research snapshot
- submission format and deadline
Actions
- Submit ideas in a common format with assumption and sketch.
- Record source, rationale, and open uncertainty directly in anonymous pack.
Output
anonymous pack
anonymous pack · source · uncertainty · next decision
Quality check
Is authorship hidden for review?
Pitfall
The first idea dominates every sprint or later evaluation follows the author's authority. Introduce a new constraint or perspective prompt and anonymise submissions before synthesis.
Timing: 10–20 minutes

Goal
Produce test selection so the core question “Which solution options can each person develop independently before collective synthesis?” can be answered with stronger support.
Inputs for this step
- anonymous pack
- research snapshot
- submission format and deadline
Actions
- Cluster mechanisms and select contrasting tests.
- Record source, rationale, and open uncertainty directly in test selection.
Output
test selection
test selection · source · uncertainty · next decision
Quality check
Is selection based on learning value and problem fit?
Pitfall
The first idea dominates every sprint or later evaluation follows the author's authority. Introduce a new constraint or perspective prompt and anonymise submissions before synthesis.
Timing: 10–20 minutes

Example output
Concrete filled scenario, fictional example
Fictional example for orientation. Counts and timings describe this case and are not universal requirements.
solo-brainstorming-beispiel.md
Concrete filled scenario, fictional example
Prompt: how can a user understand and fix an import mismatch? Sprint 1 free, sprint 2 constrained to no jargon, sprint 3 from support perspective. Result: six mechanisms collected anonymously; the group tests an explanatory preview and repairable diff.
