Why brainstorming matters more than ever
UX brainstorming gets a bad rap.
Too often, it’s treated as a checkbox. A workshop that ends in sticky notes and silence. A last-minute session once the deadline is already breathing down your neck. As a result, teams end up recycling the same safe ideas or building what a stakeholder already decided weeks ago.
But here’s what’s at stake: your product’s potential.
Every standout feature, every delightfully simple interaction, it all starts with a spark. A moment where a team dares to think differently. Without a proper brainstorming process, that moment never comes. Or it gets crushed under the weight of bias, ego, or time pressure.
In this guide: a battle-tested method for generating great UX ideas in 30 minutes. Works whether you're solo or brainstorming with your team.
30-minute brainstorming framework
Step 1: Frame the problem (5 min)
Most teams rush into solutions without defining what they’re solving. Slow down. Set the scene.
Ask: What’s the real user problem here?
- Make it human. Instead of "users don’t complete onboarding," reframe it as "users feel overwhelmed 2 minutes in."
- Make it sharp. A vague problem creates vague solutions. Get specific.
Tip: Write it like a user quote. Example: “I wanted to set up my account but didn’t know what to do next.”
Step 2: Idea sprint (10 min)
Now that you’ve nailed the problem, set a timer.
Write down as many ideas as possible in 10 minutes. No judging. No filtering. Just flow.
Use methods like:
- Crazy 8s. Fold paper into 8 squares and sketch 8 ideas in 8 minutes.
- SCAMPER. Substitute, Combine, Adapt, Modify, Put to another use, Eliminate, Reverse.
- What if. "What if users could..." and finish 20 different ways
One rule: quantity beats quality. You can't find breakthrough ideas without digging deep.
Step 3: Cluster and expand (10 min)
Time to group and build.
- Cluster similar ideas into themes (onboarding, trust, delight, etc.)
- Look for outliers or patterns.
- Expand 1–2 promising directions with more details or user stories.
Tip: Invite one other person to react. Not to judge, just to ask, “What if you took this further?”
Step 4: Gut-check with real constraints (5 min)
Now, bring it back to reality. Take your top 2–3 ideas and gut-check them against:
- User value: Does this actually solve the original problem?
- Technical feasibility: Can this be built without 6 months of backend drama?
- Business alignment: Does this tie into a team goal or KPI?
Kill what doesn’t fit. Save what does.
Why this works
This process fixes three problems that kill most brainstorming:
- No structure → Focused 30-minute framework
- Fear of bad ideas → Safe, judgment-free zones
- Unclear goals → Sharp problem definition upfront
Most teams hope ideas will appear by magic. Creativity doesn't work that way. It needs boundaries, momentum, and psychological safety.
The time limits force action. The problem framing aligns thinking. The clustering reveals patterns. The reality check keeps you grounded.
Plus, it levels the playing field. Quiet team members get heard. Loud voices don't dominate. Everyone contributes.

Why designers struggle with brainstorming
Even experienced designers fall into the same traps:
- Holding back because of the fear of being judged
- Misunderstanding the problem before solving it
- Brainstorming too late in the design process
- Getting attached to the first “good” idea
- Waiting until they’re “feeling creative”
None of these are about talent. They’re about mindset and process.
How to Improve Your UX Ideation Skills
Practice regularly.
Weekly practice:
- Run solo 30-minute sprints every Friday
- Sketch solutions for random UX challenges
- Study how improv teams use "yes, and..." thinking
- Collaborate early, even with rough concepts
Build your idea muscle:
- Try UX challenges for different industries
- Analyze competitor solutions you admire
- Join design communities and share concepts
- Document what works for your team
Brainstorming is a learnable skill, not a mysterious talent.
Time to try this yourself
Ideas are oxygen for great design, but only if they’re given room to grow.
Without a process, even the smartest team will default to safe, stale, or superficial thinking. But with just 30 minutes, you can change that.
Structure the chaos. Focus on the creativity. And walk away with real momentum. Most importantly, a good brainstorm doesn’t just produce ideas.
