5 golden rules of brainstorm
The 5 golden rules of effective brainstorming
Successful brainstorming sessions follow fundamental principles that create an environment conducive to creative thinking and idea generation.
Rule 1: Defer judgment
What it means: Suspend all criticism and evaluation during the idea generation phase. No idea should be dismissed, criticised, or evaluated until after the brainstorming session.
Why it matters: Judgment kills creativity. When participants fear criticism, they self-censor and hold back potentially valuable ideas. Creating a judgment-free zone encourages risk-taking and unconventional thinking.
How to implement:
- Establish ground rules at the start of the session
- Remind participants that evaluation comes later
- Use a "parking lot" for ideas that seem off-topic but might be valuable
- Encourage the facilitator to gently redirect judgmental comments
Rule 2: Strive for quantity
What it means: Focus on generating as many ideas as possible, without worrying about quality or feasibility during the initial phase.
What it means: Quantity leads to quality. Research shows that the most innovative solutions often appear after generating many initial ideas. The goal is to exhaust obvious solutions and push into creative territory.
How to implement:
- Set specific quantity goals (e.g., "Let's generate 50 ideas in 10 minutes")
- Use timers to create urgency and momentum
- Encourage rapid-fire idea generation
- Remind participants that every idea counts, no matter how simple
Rule 3: Build on each other's ideas
What it means: Encourage participants to listen to others' ideas and expand, combine, or modify them to create new possibilities.
Why it matters: Collaboration multiplies creativity. Building on ideas creates synergy where the whole becomes greater than the sum of parts. One person's incomplete thought becomes another's breakthrough solution.
How to implement:
- Display all ideas visibly so everyone can see them
- Ask "How can we build on this?" regularly
- Use phrases like "Yes, and..." instead of "Yes, but..."
- Encourage participants to combine multiple ideas
Rule 4: Stay focused on the topic
What it means: Ensure all ideas generated are relevant to the specific problem or topic being addressed, whilst still allowing creative exploration.
Why it matters: Focus prevents wasted time and ensures productive sessions. Whilst creativity is encouraged, maintaining relevance ensures ideas can actually be applied to the challenge at hand.
How to implement:
- Clearly state the problem or topic at the beginning
- Write the focus question or challenge visibly
- Gently redirect when ideas drift too far off-topic
- Use the "parking lot" for interesting but tangential ideas
Rule 5: Encourage wild ideas
What it means: Actively welcome unconventional, seemingly impractical, or "out-of-the-box" ideas without immediate concern for feasibility.
Why it matters: Wild ideas often contain the seeds of breakthrough solutions. What seems impossible initially might reveal a practical approach when explored further. These ideas also inspire others to think more creatively.
How to implement:
Remind participants that wild ideas can be refined into practical solutions
Explicitly invite "impossible" or "crazy" ideas
Celebrate the most unconventional suggestions
Use prompts like "What if money were no object?" or "What would we do if we had unlimited resources?"
10 proven brainstorming techniques for professional contexts
Different brainstorming techniques suit different situations, group sizes, and objectives. Understanding when and how to use each technique maximises your chances of generating valuable ideas.
Technique 1: Reverse brainstorming
What it is: A problem-solving approach that involves generating ideas for how to create or worsen a problem, then reversing those ideas to find solutions.
When to use:
- When traditional approaches aren't working
- To overcome cognitive biases or entrenched thinking
- When you need to identify root causes
- To challenge assumptions about a problem
How it works:
- Clearly define the problem you want to solve
- Reverse the problem: "How can we make this problem worse?"
- Generate ideas for creating the problem
- Reverse each idea to find potential solutions
- Evaluate and refine the reversed solutions
Example: If the problem is "low employee engagement," reverse brainstorming might generate ideas like "make meetings longer and more boring" or "never acknowledge contributions." Reversing these leads to solutions like "keep meetings concise and interactive" or "regularly recognise achievements."
Benefits:
- Breaks through mental blocks
- Reveals underlying assumptions
- Identifies root causes
- Encourages creative problem reframing
Technique 2: Virtual brainstorming
What it is: Collaborative idea generation that takes place online using digital tools, video conferencing, or asynchronous collaboration platforms.
When to use:
- With remote or distributed teams
- When scheduling conflicts prevent in-person meetings
- For teams across different time zones
- When you want to capture ideas asynchronously
- To reduce travel costs and increase participation
How it works:
- Choose appropriate digital tools (AhaSlides, Miro, Mural, etc.)
- Set up virtual collaboration space
- Provide clear instructions and access links
- Facilitate real-time or asynchronous participation
- Use interactive features like word clouds, polls, and idea boards
- Synthesise and organise ideas after the session
Best practices:
- Use tools that allow anonymous participation to reduce social pressure
- Provide clear instructions for using the technology
- Set time limits to maintain focus
AhaSlides for virtual brainstorming:
AhaSlides offers interactive brainstorming features specifically designed for professional contexts:
- Brainstorming slides - Participants submit ideas anonymously via smartphones
- Word clouds - Visualise common themes as they emerge
- Real-time collaboration - See ideas appear live during sessions
- Voting and prioritisation - Rank ideas to identify top priorities

Technique 3: Associative brainstorming
What it is: A technique that generates ideas by making connections between seemingly unrelated concepts, using free association to spark creative thinking.
When to use:
- When you need fresh perspectives on a familiar topic
- To break out of conventional thinking patterns
- For creative projects requiring innovation
- When initial ideas feel too predictable
- To explore unexpected connections
How it works:
- Start with a central concept or problem
- Generate the first word or idea that comes to mind
- Use that word to generate the next association
- Continue the chain of associations
- Look for connections back to the original problem
- Develop ideas from interesting associations
Example: Starting with "employee training," associations might flow: training → learning → growth → plants → garden → cultivation → development. This chain might inspire ideas about "cultivating skills" or "creating growth environments."
Benefits:
- Reveals unexpected connections
- Breaks through mental ruts
- Encourages creative thinking
- Generates unique perspectives
Technique 4: Brainwriting
What it is: A structured technique where participants write down ideas individually before sharing them with the group, ensuring all voices are heard equally.
When to use:
- With groups where some members dominate discussions
- When you want to reduce social pressure
- For introverted team members who prefer written communication
- To ensure equal participation
- When you need time for reflection before sharing
How it works:
- Provide each participant with paper or digital document
- Pose the problem or question clearly
- Set a time limit (typically 5-10 minutes)
- Participants write ideas individually without discussion
- Collect all written ideas
- Share ideas with the group (anonymously or attributed)
- Discuss, combine, and develop ideas further
Variations:
- Round-robin brainwriting - Pass papers around, each person adds to previous ideas
- 6-3-5 method - 6 people, 3 ideas each, 5 rounds of building on previous ideas
- Electronic brainwriting - Use digital tools for remote or hybrid sessions
Benefits:
- Ensures equal participation
- Reduces influence of dominant personalities
- Allows time for reflection
- Captures ideas that might be lost in verbal discussions
- Works well for introverted participants
Technique 5: SWOT analysis
What it is: A structured framework for evaluating ideas, projects, or strategies by analysing Strengths, Weaknesses, Opportunities, and Threats.
When to use:
- For strategic planning sessions
- When evaluating multiple options
- To assess feasibility of ideas

- Define the idea, project, or strategy to analyse
- Create a four-quadrant framework (Strengths, Weaknesses, Opportunities, Threats)
- Brainstorm items for each quadrant:
- Strengths - Internal positive factors
- Weaknesses - Internal negative factors
- Opportunities - External positive factors
- Threats - External negative factors
- Prioritise items in each quadrant
- Develop strategies based on the analysis
Best practices:
- Be specific and evidence-based
- Consider both short-term and long-term factors

- Black Hat - Critical thinking (risks and problems)
- Yellow Hat - Optimism (benefits and opportunities)
- Green Hat - Creativity (new ideas and alternatives)
- Blue Hat - Process control (facilitation and organisation)
- Assign hats to participants or rotate through perspectives
- Explore the problem from each perspective systematically
- Synthesise insights from all perspectives
- Make informed decisions based on comprehensive analysis
Benefits:
- Ensures multiple perspectives are considered
- Prevents one-sided discussions
- Structures thinking process
- Separates different types of thinking

Conclusion: The future of collaborative ideation
Brainstorming has evolved significantly from Alex Osborn's 1940s advertising agency practices. Modern facilitators face challenges our predecessors never imagined: distributed global teams, rapid technological change, unprecedented information overload, and compressed decision timelines. Yet the fundamental human need for collaborative creativity remains constant.
The most effective contemporary brainstorming doesn't choose between traditional principles and modern tools—it combines them. Timeless practices like suspending judgement, welcoming unusual ideas, and building upon contributions remain essential. But interactive technologies now operationalise these principles more effectively than verbal discussion and sticky notes alone ever could.
As a facilitator, your role transcends collecting ideas. You create conditions for psychological safety, orchestrate cognitive diversity, manage energy and engagement, and bridge creative exploration with practical implementation. The techniques in this guide provide tools for that facilitation, but they require your judgement about when to deploy them, how to adapt them to your specific context, and how to read your team's needs in the moment.
The brainstorming sessions that truly matter—those that generate genuine innovation, build team cohesion, and solve problems that matter—happen when skilled facilitators combine research-backed techniques with purposefully chosen tools that amplify human creativity rather than constraining it.
