Originally from Brussels (Belgium), and currently living in Lausanne (Switzerland), Eliott is an Interaction Designer working at the EPFL Innovation Park. His position at Coteries allows him to work on a large range of projects, both for our own products and for our customers. Every day is a new opportunity to play around with the latest trends and technologies in our dear digital industry.


Some basic rules for user experience designers

When you’re doing user experience, the golden rule is to keep in mind the people that will use the app (your customers or users). Often people get so engaged with their work that they tend to forget about the human side of the business. A UX Designer usually has a lot on his mind, functionalities, features, content and every piece that will compose the website, mobile app or whatever you’re building. Therefore, sometimes it’s hard to remember that you’re doing this for real people to use. And that you’re building the product to serve a need for your users. Not only for you!

My advice is to always test your product. Otherwise, how could you be sure your vision will match the expectations of your customers?

Therefore, you should at least gather the team around you and ask their opinion. Is it good enough, do you understand what you’re intended to do? Even better than talking with your team: invite people with personas representing your target customers in a focus group session. Show the mockups, and measure the results!

What to do when the feedback is not great

That’s OK! Forget your ego for a quick moment and think about the overall benefit. There is no bad feedback! It’s not about cheerleading and getting it right directly. Nobody can do it 100% right without exposing it to end-users. Collect all the opinions carefully… because as they come straight from the end user, that’s a gold mine!

Keep this in mind: Your product is never finished, as long as you listen to your customers’ feedbacks, you’ll want to keep improving each feature of your product.

So, how can a User Experience Designer test his assumptions?

A prototype is the answer. A rough version of the final product will be enough to test the market and see how people react to your mobile app, your website or your chatbot. Instead of creating a supposedly perfect tool, you should first try to adapt it to your customer’s needs in an early stage.

To this purpose, I normally use Invision. It’s very easy and quick to use, plus it’s great to share with customers and developers due notably to the comments/feedback section.

Although, for more advanced prototypes, it has some limitations. Therefore, I’d also recommend using framer. This tool is a bridge between design and development, you need to know a bit about coding to use it and it will take a bit more time. But on another hand, you get an exact simulation of your final product (believe me, your customers will thank you). Another great tool is

It will look like the app is finished, despite the real development has not even started!  Sometimes you can even use real data in the prototype, that’s why it feels so natural and real. We, at Coteries, try to avoid as much as possible using the traditional “lorem ipsum”.  This is the perfect way to do it.

On another hand.. don’t become stuck with prototyping!

Prototyping is required and recommended, but don’t become a slave of it. You usually do not need to prototype absolutely all components/pages of your mobile app or website (except if your customer really want to have them all… assuming he does not care paying more for it – keep it lean!). Your product needs to go to the market. You’ll get real data.
