How does Usability Testing work?

Throughout the design process, several techniques can be employed to help you increase the odds of your product being usable. Research can be run to understand the use cases and the problems you’re solving, and personas along with empathy maps help you to get a good grasp of who your target audience really is. You might even mirror certain competitor activities and run heuristic evaluations to check for basic usability errors.

Usability testing examples

However, until you test, you can’t really tell for sure whether you have designed something that is actually usable. There’s nothing more painful than watching someone try your product then say loud and clear “Hm, what do I do now? This is confusing”.

It’s painful, but insightful.

Usability testing tells you where the issues lie then points you in the right direction. In this article, we offer some guidance on how to write testing scenarios and give some usability testing examples.

Testing early – with paper prototypes, even – can help save budget and will increase the odds of your being successful, and it’s incredibly simple to do. Usability Testing is simply asking a user to try to accomplish something specific with your product. This might take place in somewhere as informal as a coffee shop or through a detailed study conducted in a lab. It can even be done remotely. Usability testing tools like allow you to watch someone across the world using your website to accomplish tasks that your write.

How to Create Task Scenarios

Let’s assume you own a boat rides company in Amsterdam and you decide to build a simple landing page where people can go to book a boat ride.

There is one clear metric to success: How many people book rides, which in turn generate revenue to your business. Therefore, booking rides should be extremely easy to do and how to actually do it should be obvious, even.

It doesn’t matter if people “understand what the website is about” but can’t actually book. Or if they recognize your brand, or if they find information about the location and timetable. In the end, all that matters is if they can book or not.

If you were to run a quick usability testing by perhaps, asking a stranger at a coffee shop to try out the website and you offer to pay for their coffee in return, you would have to understand how to do the main task – booking a ride. With this in mind, come up with a task scenario to test it:

“You and your sister will be visiting Amsterdam for the first time next week. Use to book a 2-person boat ride for Tuesday”

When writing task scenarios, you should follow a few general guidelines:

  • The tasks should be realistic because if a user can identify with the situation, they are more likely to be engaged. If your subject is a father of two girls for example, avoid asking him to buy gifts for his two boys. The more relatable a task is, the better.
  • Avoid providing clues. You can’t really test whether your product works well or not if you are helping the user. In the example used above, you wouldn’t want to say “…Use the blue button in to book a 2-person boat ride for Tuesday”.
  • Be specific. The subject shouldn’t be asking you, the moderator, for clarification of what you want them to do. You noticed the example was specifically saying “book a 2-person boat ride for Tuesday” instead of just “book a ride”. Also, make sure you have the correct outcome for a task (“Open” doesn’t have a right or wrong end goal, which means you can’t measure whether they were successful or not). Also, make clear that you are not asking for their opinion. Asking them “What do you think of feature X?” doesn’t give you feedback as to whether the feature is usable or not – so instead, ask your subject to try out feature X.

(On a quick note, assuming you have more resources and time, it’s okay to test for things like: Can the user understand what the website is about? Can they find the contact information easily? Is pricing information easy to find? In this example I intentionally chose to focus on the core objective, and even with more resources, you should still have the main goal – bookings – in mind.)

Some Examples of Usability Testing

Hopefully, by now you know what Usability Testing is and why it matters. You also learned what task scenarios are and how to write them. Next, we’ll take a look at a number of popular websites and apps, and write down a useful list of example task scenarios for each one of them.

If we were to run actual usability testing studies on each one of these products, a lot more work would be involved than just writing a few task scenarios. The goal here is to give you some real world examples to make it easier to understand what usability testing questions look like, but not what an entire usability study looks like. We have intentionally only picked a few task scenarios so won’t be covering the entire set of tasks applicable to each product.

We will take a look at KAYAK, AirBnB, Uber and DoorDash.

Usability Testing Example 01 – Flight Booking with KAYAK (Or, KAYAK) is a robust travel website. Available in 18+ languages, it allows visitors to book hotels, flights, train rides, rent cars, buy travel packages, book cruises, track flights and more. It’s wildly popular among travellers and was named on the Best Apps for Business; Travellers by Travel + Leisure. TIME named it one of the 50 Best Websites of 2009.

You are a bit confused and want to clarify the situation with the website where you booked the trip. Go to and find their customer support phone number.

Usability Testing Example 02 – Accommodation Booking with Airbnb

Airbnb, founded in 2008, is now well known around the world. The online marketplace allows people to rent their homes (or private and shared rooms) to travellers, who can book them. It has recently expanded to also offer bookable “Experiences” – for example, a coffee shop tour in a city with a local who knows the best spots. In addition, it offers guides to major cities and lists events available in some of them.

  • Contacting Customer Support
    You just arrived at your Airbnb accommodation, but the apartment doesn’t look like the listing and you can’t reach the host. Go to and find the number to call customer support and resolve the situation.

Usability Testing Example 03 – Getting Transportation with Uber

Uber most likely doesn’t need an introduction: It’s the highest valued tech startup in the world right now. Available in over 400 cities around the world, it connects passengers with drivers for hire. Anyone (who passes a background check) can start driving in the platform, and anyone can call an Uber car by using one of its mobile apps. It recently also started doing food delivery in some areas – UberEATS – but we won’t be focusing on that for the examples below.

Example Task Scenarios:

  • Getting a Ride Somewhere
    You have to attend an event in downtown New York that starts in less than two hours. Open up the Uber app in your phone and get the cheapest ride available there.
  • Reviewing a Ride
    You just had a bad experience; the driver refused to drop you off at the requested location. Open up the Uber app in your phone and review that ride.
  • Adding a Payment Method
    You recently changed credit cards. Open up the Uber app in your phone and add your new card.
  • Contacting Customer Support
    You were incorrectly charged an extra $20 for a ride, yesterday at 3:20pm. Open up the Uber app in your phone and contact customer support to solve the issue.
  • Signup as a Driver
