You hear a lot about technical debt in product development, but not nearly enough about what happens when the design side starts to fall apart. It builds up the same way - quick decisions made under pressure, things added without cleaning up what’s already there, little inconsistencies that don’t seem worth addressing. But over time, those decisions pile up. 

This isn’t just a visual problem. It affects usability. It affects team speed. It affects trust. When your product doesn’t feel coherent—when things don’t behave the same way from screen to screen—users feel it. They may not know why something feels clunky or off, but they notice. Internally, it’s the same story. Designers spend more time debating decisions that used to be obvious. Developers ask, “Which version of the color palette are we using again?” Small updates take longer. New team members get stuck just trying to figure out what’s current and what’s legacy.

Eventually, the shortcuts stop saving time and start sinking the ship. You’re no longer building a product; you're just servicing its decline.

The symptoms of design debt are easy to spot

Here are some things to look for:

• The same component exists as five slightly different versions

• Screen are being built from scratch, even when they are supposed to be similar

• A small copy change turns into a multi-week rebuild because nothing quite lines up anymore

It’s not that any of these things are dramatic on their own. They creep in gradually, and they’re easy to rationalize: “We’ll clean it up later.” “It’s just a one-off.” “We didn’t have time to do it the right way.” Again, the same as tech debt.

And then it’s launch after launch after launch, and before you realize it, everything unravels.

So what do you do about it?

This isn’t about dropping everything to rebuild your design system from scratch. You might already have the pieces, they’re just scattered, inconsistent, or underused. What matters is you recognize it, and make deliberate moves to clean it up.

1. Agree that it’s happening

Half the battle is acknowledging it. Most teams know they’ve cut corners, but unless someone points out how that’s affecting everything else - the speed of work, the confidence in design decisions, it tends to get ignored. Call it out, and with clarity. You can’t fix something you haven’t named.

2. Take stock of what exists

Start by gathering examples. Look through your product and note where things have diverged with components, patterns, layouts, interactions. Take screenshots of the same modal from different parts of the product and put them next to each other. Do the same for buttons, navigation patterns, or text field styles. 

When people can see the inconsistency side-by-side, it becomes easier to rally around fixing it. It’s no longer a vague idea - it’s visual, tangible, and real.

3. Establish some shared rules

You don’t need a full-blown design system with tokenized theming and every edge case solved. But you do need a source of truth. Pick a few components that cause the most trouble, and define the go-forward version. Label them clearly. Archive the rest.

It’s fine if not everything is perfect. The goal isn’t to retroactively fix the entire product overnight. It’s to make future work easier.

4. Clean as you go

The way out isn’t a big dramatic overhaul, it’s disciplined cleanup in the margins. When you’re building something new and you spot a pattern that’s off, fix it then. Update the spec, and swap in the right version. Get everyone in the habit of cleaning up as they go.

It sounds basic, but this is how you dig out.

Why does all this matter?

These things don’t show up in analytics. There’s no dashboard that says your buttons are inconsistent. But your team feels it, and your users feel it. And over time, your product suffers for it.

You don’t need to fix everything right now, but you do need to care. The longer you wait, the slower things get. And the more everyone starts to accept the mess as normal.

The good news? This is fixable. All you have to do is start.
