Brainstorming Toolkit

Brainstorming is one of the most widely recognised creativity techniques in the world. It appears in classrooms, boardrooms, workshops, innovation labs and community projects. Despite its popularity, brainstorming is often misunderstood and poorly facilitated.

Many teams gather in a room, ask for ideas and hope creativity will emerge naturally. Sometimes it does. More often, however, conversations become dominated by a few voices, ideas are judged too early and creative potential remains untapped.

Effective brainstorming is not random.

It is a structured process designed to generate possibilities, encourage collaboration and expand thinking before evaluation begins.

Within the Explore stage of the 5E Design Thinking Framework, brainstorming helps individuals and teams move beyond obvious solutions, challenge assumptions and discover opportunities that may otherwise remain hidden.

The purpose of brainstorming is not to find the perfect answer immediately.

The purpose is to create enough possibilities that better answers can emerge.

Brainstorming is a structured ideation process used to generate a large number of ideas within a limited period of time.

Brainstorming can be conducted:

• Individually
• In small groups
• Across large teams
• In workshops
• Online
• In-person

The emphasis is on idea generation rather than idea evaluation.

During brainstorming, quantity matters.

Judgement comes later.

Many people underestimate how difficult it is to think beyond familiar solutions.

Humans naturally rely on:

• Existing knowledge
• Previous experiences
• Familiar approaches
• Established assumptions

While these habits can be useful, they can also limit innovation.

Brainstorming helps teams:

• Explore alternatives
• Generate possibilities
• Encourage creativity
• Discover opportunities
• Build collaborative ownership
• Challenge assumptions
• Increase idea diversity

The more possibilities that exist, the more opportunities there are for innovation.

Successful brainstorming sessions typically follow four principles.

1. Defer Judgement

Ideas should not be evaluated while they are being generated.

Premature criticism often limits creativity and discourages participation.

Instead of asking:

Will this work?

Ask:

What else is possible?

Evaluation occurs later.

2. Generate Quantity

Many breakthrough ideas emerge only after obvious solutions have been exhausted.

The first few ideas are often predictable.

Greater creativity frequently emerges after sustained exploration.

The goal is volume.

3. Build on Ideas

Brainstorming is not simply about individual contributions.

Participants should expand, combine and improve ideas generated by others.

Innovation often emerges through connection rather than invention.

4. Encourage Wild Ideas

Unusual ideas can open unexpected pathways.

The objective is not immediate feasibility.

The objective is possibility.

Many innovations initially appeared unrealistic or unconventional.

Brainstorming is primarily a divergent thinking activity.

Divergent thinking focuses on expansion.

Questions include:

• What if?
• Why not?
• What else?
• How might we?

The purpose is to explore multiple directions before selecting a path forward.

Convergent thinking follows later when ideas are evaluated and refined.

Successful brainstorming begins before participants enter the room.

Define the Challenge

A clear challenge statement helps focus creativity.

Examples include:

• How might we improve student engagement?
• How might we reduce waiting times?
• How might we improve onboarding experiences?
• How might we encourage sustainable behaviour?

Good challenge statements are:

• Clear
• Open-ended
• Inspiring
• Human-centred

Select Participants

Diverse perspectives strengthen ideation.

Consider including:

• Users
• Stakeholders
• Subject matter experts
• Students
• Customers
• Community members

Innovation often occurs at the intersection of different viewpoints.

Prepare the Environment

Creative environments support participation.

Consider:

• Whiteboards
• Sticky notes
• Large paper surfaces
• Visual prompts
• Digital collaboration tools

The environment should encourage contribution and experimentation.

Classic brainstorming remains one of the simplest ideation techniques.

How It Works

• Present the challenge.
• Participants suggest ideas.
• Ideas are recorded visibly.
• Evaluation is postponed.
• Quantity is encouraged.

Best For

• Small groups
• Quick ideation
• Early exploration

Strengths

• Easy to facilitate
• Flexible
• Accessible

Limitations

• Dominant personalities may influence discussion.
• Quiet participants may contribute less.

For this reason, alternative formats are often useful.

Brainwriting combines individual thinking with collaborative ideation.

Participants write ideas silently before sharing them with the group.

Why It Works

Brainwriting:

• Reduces group pressure
• Encourages participation
• Generates diverse ideas
• Limits dominance effects

Simple Process

• Pose the challenge.
• Participants write ideas independently.
• Papers are exchanged.
• Participants build upon existing ideas.
• Multiple rounds occur.

Best For

• Introverted participants
• Larger groups
• Structured workshops

Round Robin ensures balanced participation.

Participants contribute ideas sequentially around a group.

Benefits

• Equal participation
• Reduced dominance
• Increased engagement

Best For

• Team workshops
• Classroom activities
• Structured facilitation

Silent brainstorming removes discussion entirely during idea generation.

Participants capture ideas independently before sharing.

Benefits

• Deep thinking
• Reduced social influence
• Greater diversity of ideas

Best For

• Complex problems
• Introverted participants
• Distributed teams

Crazy 8s is a rapid ideation technique commonly used in design thinking.

Participants:

• Divide a page into eight sections.
• Generate one idea per section.
• Complete all eight ideas within eight minutes.

Benefits

• Forces rapid thinking
• Prevents overanalysis
• Produces idea variety

Best For

• Concept generation
• Early design phases
• Workshops

Instead of asking:

How might we solve this problem?

Ask:

How might we make this problem worse?

Participants generate negative ideas first.

These ideas are then reversed to reveal opportunities.

Example

Challenge:

Improve customer service.

Reverse Question:

How could we create the worst customer service imaginable?

Insights often highlight hidden problems and opportunities.

SCAMPER is a structured creativity technique.

Participants examine an existing product, service or idea through seven prompts:

Substitute

What could be replaced?

Combine

What could be merged?

Adapt

What could be borrowed?

Modify

What could change?

Put to Another Use

How else could it be used?

Eliminate

What could be removed?

Reverse

What could be rearranged?

Benefits

• Structured creativity
• Easy facilitation
• Strong concept development tool

Random stimuli help break predictable thinking patterns.

Process

• Select a random word, image or object.
• Explore connections to the challenge.
• Generate ideas based on those connections.

Example

Random object:

Umbrella.

Challenge:

Improve university onboarding.

Potential inspirations:

• Protection
• Guidance
• Support
• Preparation

Unexpected connections often generate innovative ideas.

The facilitator plays an important role.

Encourage Participation

Ensure all voices contribute.

Use prompts where needed.

Capture Every Idea

Visibility matters.

Ideas should be recorded clearly and consistently.

Maintain Momentum

Energy tends to fluctuate.

Facilitators should encourage continued exploration.

Protect Psychological Safety

Participants should feel comfortable sharing unfinished thoughts and unconventional ideas.

Psychological safety is essential for creativity.

Judging Ideas Too Early

Evaluation should follow ideation.

Focusing on the First Idea

Strong ideas often emerge later.

Allowing Dominance

All participants deserve opportunities to contribute.

Seeking Perfection

Ideas do not need to be polished immediately.

Generating Too Few Ideas

Quantity frequently improves quality.

Modern collaboration increasingly occurs online.

Useful tools include:

• Digital whiteboards
• Shared workspaces
• Online sticky note systems
• Collaborative mind mapping tools

Virtual brainstorming can be highly effective when sessions are structured and facilitated well.

Brainstorming is a powerful educational tool.

Students can use brainstorming to:

• Develop project ideas
• Explore research questions
• Generate business concepts
• Design learning solutions
• Solve complex problems

The process encourages creativity, collaboration and critical thinking.

Most importantly, it helps students recognise that innovation begins with possibility rather than certainty.

Innovation teams frequently use brainstorming to:

• Explore opportunities
• Develop concepts
• Generate strategic options
• Improve services
• Identify future possibilities

However, brainstorming should not exist in isolation.

The strongest innovation processes connect brainstorming with:

• Research
• User insight
• Prototyping
• Testing
• Experimentation

Ideas become valuable when they lead to learning and action.

30-Idea Challenge

Objective

Push beyond obvious thinking.

Instructions

• Define a challenge.
• Generate 30 ideas individually.
• Do not evaluate ideas.
• Review ideas only after all 30 are created.

Expected Outcome

Greater creative diversity and reduced fixation on initial concepts.

Estimated Time

20–30 minutes.

Select a current project.

Apply three different brainstorming methods:

• Brainwriting
• Crazy 8s
• Reverse Brainstorming

Compare the ideas generated by each method.

Which approach produced the most surprising insights?

• Which brainstorming techniques do you use most often?
• Which techniques are new to you?
• How psychologically safe is your team's ideation process?
• Are ideas being judged too early?
• How could participation become more inclusive?

• Brainstorming is a structured ideation process.
• Quantity supports creativity.
• Judgement should be deferred.
• Diverse perspectives strengthen outcomes.
• Facilitation matters.
• Different brainstorming techniques achieve different goals.
• Psychological safety encourages participation.
• Innovation benefits from exploration before evaluation.

Choose a current challenge and facilitate a brainstorming session using a method you have never used before. Focus on generating at least 50 ideas before discussing which ones should move forward.
