UX Audit Under 15 Minutes: The Brutally Honest Sanity Check

A sketch of a modern chair featuring a soft seat and one asymmetrical leg.

Most UX audits are long, expensive, and full of beautifully formatted reports you’ll never read twice.

This isn’t that.

This is the UX sanity check — the quick-and-dirty, seven-question sweep I use when I want to know if a product is healthy enough to survive the week. It’s not a replacement for a proper deep-dive UX audit, but it’s a great way to find the obvious leaks before they sink you.

And yes — you can actually do this in 15 minutes. No post-its. No mood boards. No design thinking theatre.


The $9K UX Audit That Started With 15 Minutes

Founder calls. SaaS project management tool. 28 employees. Growing but messy. “We need a full UX audit. How much and how long?”

Full UX audit quote: $9,200, three weeks (heuristic analysis, user flows, session recordings, competitive analysis, documentation, the works).

I said: “Before you spend $9K, give me 15 minutes. I’ll run a sanity check. If your product passes, you probably don’t need the full audit. If it fails, we’ll know exactly where to dig deeper.”

Fifteen minutes later: Failed 4 out of 7 checks.

The problems weren’t subtle. They were obvious, measurable, and actively costing them customers. Here’s what I found:

Check 1 (First-time user value): Failed
Onboarding required 11 steps before showing any actual project management features. Drop-off rate: 64% of new signups never created a project.

Check 2 (Primary CTA visibility): Failed
Main “Create Project” button looked identical to “Import CSV,” “View Tutorial,” and “Settings.” I asked the founder to point it out on a screenshot. Took him 9 seconds to find it.

Check 3 (Real words vs jargon): Passed
Navigation was clear. Labels made sense.

Check 4 (Mobile experience): Failed
Form for creating tasks cut off the submit button on screens under 1366px width. 41% of their traffic came from 13″ MacBooks. Completion rate on those devices: 28% vs 67% on larger screens.

Check 5 (Undo mistakes): Passed
Had confirmations for destructive actions.

Check 6 (Support tickets): Failed
Top support ticket (43 instances in 30 days): “How do I add team members?” The button existed. It was in Settings → Account → Team Management. Nobody found it there.

Check 7 (Right metrics): Passed
They tracked task completion rates, project creation flow, and activation metrics.

Four failures. Not subtle “nice-to-have” improvements. These were revenue-impacting problems hiding in plain sight.

“Okay,” founder said. “What’s the fix?”

One sprint. Three weeks. $3,400 in focused product design work:

  1. Cut onboarding from 11 steps to 4
  2. Made “Create Project” button 2x larger, different color, always visible
  3. Moved “Add Team Members” to main navigation (top right, where humans look for it)
  4. Fixed mobile form layout (moved submit button above fold)

Results after two weeks:

  • Onboarding completion: 36% → 72%
  • Task creation on mobile: 28% → 63%
  • “How do I add team members?” support tickets: 43 → 6
  • Time to first project created: 18 minutes → 4 minutes

Total spent: $3,400.
Total saved by not doing full UX audit first: $5,800.

Then we did the proper deep-dive UX audit. Because now we knew it was worth it. But we fixed the bleeding first.

That’s what a 15-minute sanity check does. It separates “this needs immediate surgery” from “this could use optimization eventually.”


Why Bother With a 15-Minute UX Audit?

Because most teams wait until things are on fire before asking, “Hey, should we maybe check if users can actually use this?”

By then, you’re hemorrhaging conversions, support tickets are piling up, and your developers are quietly updating their LinkedIn profiles.

A quick UX audit gives you:

  • Immediate insight into where you’re losing users
  • Prioritized list of fixes (without analysis paralysis)
  • Ability to stop repeating the same mistakes on new features

If you pass all 7 checks, you can sleep easier. If you fail more than 2… we should probably talk.


The 7-Point UX Sanity Check

Each check takes 2 minutes or less. Yes, really.

1. Can a First-Time User Get to Value in 3 Clicks or Less?

If it takes 12 steps, 4 forms, and a welcome video to get someone to the thing they signed up for, you’ve lost them.

This is where you identify onboarding bloat — the “helpful” steps that are actually hurdles. Every extra screen between signup and value is another chance for users to leave.

How to check:

  • Open incognito browser
  • Sign up as new user
  • Count clicks/screens until you reach core product value
  • If it’s more than 3, you have bloat

Quick fix: Strip out anything non-essential from first-time flow. Let users succeed before you teach them advanced features. Onboarding that explains before showing fails. Showing value first works.

The project management tool story above? Classic case. 11 steps of “tell us about your team” and “set your preferences” before users could create a single project. No wonder 64% dropped off.

Cut to: Name → Email → Password → Create first project. Four steps. Preferences can wait.

2. Is Your Primary Call-to-Action Impossible to Miss?

If your main “Buy Now” or “Start Free Trial” button looks exactly like every other button on the page, you’ve buried your revenue.

CTAs need visual priority — size, color, placement. One primary action per screen. Everything else is secondary.

How to check:

  • Open your key pages (homepage, pricing, dashboard)
  • Take screenshot
  • Show someone who’s never seen it
  • Ask them to point out the main action
  • If they hesitate or point to wrong thing, you failed

Quick fix: Pick one primary action per screen. Make it obvious, make it bold, make everything else look less important.

In proper UX design work, this is called visual hierarchy. In practice, it means stop making every button purple just because your brand color is purple.

The founder who took 9 seconds to find his own CTA? That’s not a design problem. That’s a money problem. If he can’t find it instantly, customers definitely can’t.

3. Are You Using Real Words or Internal Jargon?

If your navigation reads like your Jira board, you’re doing it wrong.

Users don’t care about your internal feature codenames. They don’t know what “Resource Allocation Matrix” means. They want plain language that matches their goals.

How to check:

  • List all navigation labels, button text, section headers
  • Remove internal context
  • Would your grandmother understand what each one does?
  • If no, rewrite

Quick fix: Rewrite labels and tooltips in words your users actually use. If you wouldn’t say it to a customer in conversation, it doesn’t belong in your UI.

I once worked on a tool that had “Workstream Optimization Dashboard” in the nav. Nobody clicked it. Renamed to “Task Planner.” Usage tripled. Same feature. Different words.

This isn’t about dumbing things down. It’s about clear communication over clever naming. Clever loses to clear every time.

4. Does Your Product Work on the Device Your Users Actually Use?

You’d be amazed how many “mobile-friendly” products turn into scrolling nightmares on phones. Or how many desktop dashboards are unusable on 13″ laptops (looking at you, every enterprise SaaS built by people with 27″ monitors).

How to check:

  • Check analytics for top 3 devices/browsers
  • Test your product on those exact configurations
  • Complete your most important user flow on each
  • Note what breaks, cuts off, or requires horizontal scrolling

Quick fix: Fix the top 2 device/browser combinations first. That covers 60-80% of your users.

The 13″ MacBook problem from the story above? 41% of traffic. Submit button invisible. Completion rate 28% versus 67% on larger screens. That’s not a minor issue. That’s 41% of users hitting a broken experience.

Good UX/UI design doesn’t mean “looks good on my MacBook Pro.” It means works everywhere your users actually are.

5. Can a User Undo a Mistake Without Rage-Quitting?

No confirmation before deleting something important? No “Undo” after a big action? Congratulations, you’ve just given someone a panic attack and a reason to switch to your competitor.

How to check:

  • List all destructive actions (delete, remove, cancel, archive)
  • Test each one
  • Is there confirmation? Can you undo it?
  • If no to either, you failed

Quick fix: Add clear confirmations for destructive actions and an easy way to reverse them. This isn’t “nice to have” — it’s basic user safety.

I’ve seen a B2B invoicing platform with no confirmation before sending invoices. Someone could accidentally bill a client $120,000 instead of $12,000. One typo. No confirmation. No undo. Just an embarrassing phone call and potential lawsuit.

That’s not a UX problem. That’s a negligence problem dressed as interface design.

6. Are Your Most Frequent Support Tickets Actually UX Bugs?

If your support team answers the same “How do I…?” question every week, that’s not a training issue. That’s a design issue.

Users shouldn’t need support to do basic tasks. If they do, your UI is failing.

How to check:

  • Pull top 10 support tickets from last 30 days
  • Count how many are “How do I…” questions
  • If more than 2 are about basic tasks, your UX is broken

Quick fix: Go through those tickets. Fix the flow or the copy. If people can’t find it, move it. If they can’t understand it, rewrite it.

The “How do I add team members?” support ticket? 43 instances in 30 days. Button existed. Nobody found it in Settings → Account → Team Management.

Moved to main nav. Tickets dropped to 6. That’s 37 fewer support conversations. At $25 per ticket in support time, that’s $925/month saved. $11,100 annually. From moving one button.

This is why hidden features cost you money. Not just in lost functionality. In support overhead.

7. Are You Tracking the Right UX Metrics?

If you’re only watching DAU/MAU or signups, you’re missing the leaks.

Vanity metrics look good in board decks. They don’t tell you where users are struggling.

How to check:

  • List metrics you track weekly
  • For each core user flow, do you measure:
    • Completion rate
    • Drop-off points
    • Time to complete
    • Error rate
  • If not, you’re flying blind

Quick fix: Pick one success metric per core flow. Track it. Improve it. Repeat.

Signups are meaningless if 70% never activate. Trial starts are useless if 80% don’t complete onboarding. DAU is vanity if users log in and leave confused.

Track what matters: Can users complete the task they came to do? How long does it take? Where do they get stuck?

That’s proper SaaS product design measurement. Not “how many people showed up” but “how many people succeeded.”


What to Do If You Fail the Sanity Check

Failing 1-2 checks?
Make a quick fix plan. Schedule them in your next sprint. Not urgent, but worth addressing.

Failing 3-4 checks?
You need focused UX/UI cleanup before adding more features. Stop building on broken foundations.

Failing 5+ checks?
Stop building new features immediately. You’re just adding debt on top of debt. Fix what’s broken before shipping more broken things.

The beauty of quick UX audits is they force prioritization. It’s not about making everything perfect — it’s about making sure nothing critical is actively driving users away.


When You Need the Full Deep Dive

The 15-minute sanity check finds obvious problems. It won’t catch:

  • Subtle usability issues requiring session analysis
  • Complex workflow inefficiencies
  • Competitive positioning problems
  • Accessibility compliance gaps
  • Design system inconsistencies

That’s when you break out the big guns — full product audit, heatmaps, session recordings, user interviews, the works. Proper website design strategy for SaaS products requires both: quick checks to catch critical issues, deep audits to optimize performance.

But you don’t need a $9K UX audit to start plugging obvious leaks. Run the 15-minute check first. Fix what’s broken. Then optimize what’s working.


The Bottom Line

Great UX doesn’t happen by accident. And it definitely doesn’t happen if you never check the basics.

Run this sanity check quarterly. It’ll keep you honest, keep your users happy, and keep your developers from quietly weeping into their coffee.

Fifteen minutes. Seven questions. No excuses.

If you pass all seven, you’re ahead of 80% of products I audit. If you fail more than two, you know exactly where to start.

And if you fail all seven? Well, at least now you know why your conversion rates are terrible.
