As a designer you’re expected to make the impossible happen. Time and time again, you’re expected to take an incredibly complex process and make it easy, simple and beautiful. When it’s handled well, you feel like a rock star.

When we fail to live up to those heavy expectations, it leaves many of us feeling… deflated. Designers tend to be perfectionists by nature, we’re our own worst critic. We take those mistakes personally, as if we’ve somehow ruined everything.
But these discouraging moments, if you accept them, are incredible opportunities for growth and learning. Here’s a dirty little secret: most of the mistakes you make aren’t your fault. here’s the terrible part: you’ll be punished for them anyway.

What we’re missing is a knowledge of people

It’s not like designers start a new job or project with the goal of screwing things up. With most of us it’s actually the opposite. We obsess over the little details, the insignificant things most people feel don’t matter. Most designers realize the importance of attention to detail.

That isn’t the problem. It’s what we don’t know. The things we weren’t taught that make a huge impact on our work. If you’re formally (or informally) trained, you’re encouraged to study your craft. You’re expected to learn and understand the principles of design, about communication, visual and color dynamics, color etc. But there’s something missing.

What we’re missing is a knowledge o people. Designers aren’t taught to study people in school. We know our craft and we understand aesthetics, but we’re never really given in-depth training on people. Our lack of understanding creates a knowledge gap. This gap affects our designs, leading us to make some incredibly common but unexpected UX mistakes.


Designers are reasonable people. They spend a lot of time dealing with user interfaces so they have an intuitive knowledge of how things work on the web.

“That’s common sense!” they tell themselves. Only it’s not common sense. It’s common knowledge to you, the designer. You spend a significant amount of time in this environment, so you just get it.

You’re a professional. Users? Not so much. This is why these assumptions are so devastating. We assume the users:

Know which questions to ask
Understand the controls
Know what our icons, symbols and logos mean
Give us their undivided attention
Will read or follow the instructions we give them
Know how to find what they want

See the problem? These assumptions are reasonable. Most designers have made these assumptions. And therein lies the problem. These assumptions aren’t based in reality.

Some users are clueless
Some are seeing and using our controls for the first time
Others find our visuals confusing
A few are distracted multi-taskers who are short on time or resources.
Others refuse to follow your instructions
While most aren’t sure they know what they’re looking at

Your job as a designer is to direct and thin the herd. Sort out those who are right for you, move them through your process, and get them to the finish line. Everyone else should be shown the door.

Avoiding this UX mistake requires lots of courage. But it also requires something more important: a clear understanding of the goal.

That piece you’re designing, what is it supposed to accomplish? The website you’re developing, what’s the goal?


And the reason it’s mandatory? Your boss, the committee, a client, someone in charge is going to demand that you go against that goal. What’s worse is that you know what’s going to happen.

Your experience tells you this won’t end well. If you give them what they want things won’t go as well as it should. It may fail miserably. It’s easy to go along with the boss. “They’re the ones signing the checks, I just do as I’m told.”

It’s important that you fight for your boss, even when they refuse to fight for themselves. If they’re asking you for something that will hurt them, speak up. Deliver the bad news. Get them to understand the mistake they’re making.

A habit of not speaking up means your portfolio will be filled with mediocre work.

Most designers won’t do it. They’re afraid they’ll lose their job or hurt their career. Which is exactly what will happen if you say nothing. How do I know? Experience. Those mistakes are probably going to end up in your portfolio. A habit of not speaking up means your portfolio will be filled with mediocre work.

And the A-player employers, the kind you’d love to work with? They can tell. Make enough of these mistakes and it becomes difficult to hide.


What if you’re part of a team where the planning and design decisions have already been made? Talk it over with others on your team. Make your case with solid evidence (e.g. research, reports, data, etc.). Then, make your case with decision makers. It feels impossible, but it’s definitely doable. Just start small and take it slow. You’re a professional. You have the tools you need to find the UX mistakes others miss. You make the complex easy, simple, and beautiful.
