•  19.04.2023
Usability Testing is the ultimate way to determine if your website or app is functioning as it is intended to. Are your visitors able to achieve their goals, easily and effectively? Is there room for improvement? We are here to show you how to tackle task-based usability testing, easily as it gets.

User experience is an incredibly important aspect of digital products nowadays. When failing to continuously test and optimize the usability of your website it may seem chaotic or out of date. With usability testing studies you can get valuable insights and user feedback, and make design decisions based on reliable data, rather than guesswork.

Today we will be focusing on task-driven usability tests. We will talk about what benefits usability testing and how you can implement it remotely within minutes with our ready-to-go example and a 10-step process to running task-oriented usability studies for your websites, web apps, or prototypes.

Article Summary

What is task-based usability testing?

Your customers expect to easily navigate your website, get to the products they are looking for and find all the information they need. They expect an issue-free experience while using your website. This is where they often get disappointed. As we all know, confusing and bug-ridden websites expectedly lead to low conversions, high bounce rates, etc.

However, there are ways to combat this problem. Task-oriented usability studies combine qualitative research methods to provide you with in-depth explanations, and as much context as possible while not forgetting about important quantitative metrics and statistics. They take into account that your users need to accomplish specific goals on your website and they should be able to do so easily. 

A task-oriented usability study is built around a real-life task and scenario to simulate the real user experience and encourage users to interact with your product interface naturally. You can measure user success rate and test a website’s ability to do what it was built for – satisfying a customer from the user’s point of view and bringing conversions.

The task is simply an action you want your users to be able to complete in your interface. This type of user testing can be conducted in person or online with the help of specialized usability testing tools.

Why you should try task-based usability tests?

Every website, web app, and mobile app is built with a goal and user goals in mind. For example, the main goal of an e-commerce website is to sell products, additional user goals could be to let users subscribe to the newsletter (to sell more products later on and create engagement).

When users experience issues stopping them from completing their goal it creates a bad brand experience, meaning your customers will be less likely to return to your store and create revenue.

Unfortunately, even the most optimized or well-coded websites don’t get this aspect perfectly, as it is next to impossible to predict the exact way your actual users will be using your digital products. To battle this problem, you need to observe how your users interact with the interface and features in the context of the real day-to-day user experience.

Task-oriented usability testing allows you to qualitatively analyze how your users go about solving the tasks set by you, why users could not complete the test tasks successfully, or what distracted them during their efforts.

When is the right time to use task-based usability testing?

It is best to incorporate this type of usability test at more stages of development, to avoid developing a product that will later need changing.

When you can think about a specific usability testing scenario, you can create usability tasks. You can then conduct a task-oriented usability study on a high-fidelity prototype with a help of a Prototype Testing tool or conduct live Website Testing or Mobile App Testing.

It is perfect for when you are looking for detailed answers from a larger number of your users to questions such as: 

  • Why does your e-commerce website have a high abandonment rate at the checkout?
  • Why don’t your users sign up for your newsletter?
  • What causes low conversions? 
  • Is your site navigation effective and intuitive? 
  • Can users find the information they are looking for about your company? etc. 

You can learn more about when to conduct usability testing in our Complete Guide to Usability Tests.

Advantages of remote task-based usability testing

  • Higher completion rate due to motivation to complete the task by setting relatable scenarios (for example: Subscribe to our newsletter.)
  • Testing on real day-to-day tasks that make it relatable to your users
  • Realistic results when put into practice correctly
  • Actionable insights to improve on 
  • Less costly than in-person interviews
  • Qualitative insights scalable to any number of users

Disadvantages of remote task-oriented usability tests

  • Poorly prepared usability tasks can lead to skewed data and even harmful results when changes are made based on the data
  • Unrelatable scenarios discourage users from completing tasks
  • Possible incorrect identification of goals 
  • Only makes sense to conduct on high-fidelity prototypes or finished products

How to create a task-based usability test?

Firstly, the most important part of well-structured task-oriented usability testing is setting the tasks correctly, so they are relatable to the testers and much easier to interpret. Creating great usability tasks is important in order to not collect skewed data. Let’s tackle that first.

Here you will find an example you can use as a stepping stone to creating your first study, making it easier for you to grasp the whole concept.

Example: Usability test for an e-commerce website

Start by setting the goals of your website. In this case, customers have to be able to order products, check and track their orders and get customer support without any difficulties. 

Some of the common mistakes e-commerce websites make that put customers off are:

  • counter-intuitive filtering and searching for products
  • inadequate payment methods
  • bad return policy and refunds
  • excessive load time of the website 
  • complicated shopping cart
  • long delivery time

To make sure you avoid these mistakes, we prepared these 3 sample tasks for you to start testing in no time.

Task 1: Find the least expensive smartphone in our offer and find more details about it.

Task 2: Find out whether it’s possible to use Paypal to pay in our online shop.

Task 3: Find how we can ship your order and which method is the least expensive.

How do you write tasks for usability tests?

When writing usability tasks it’s important to focus on real-life user scenarios and their interactions with your digital product. Define a clear goal of what you’re trying to find out in your usability test and put together a list of usability testing tasks and questions that correspond to those goals. 

When you’re conducting your first usability test with the product a great tip is to focus your tasks on some of the most common actions users take with it. You can see that in the example above where we are testing an e-commerce website, the first task asks the user to find a specific product and details about it. Testing that user scenario is a priority for an e-commerce store as one of their main user goals is to get people to find and buy their products.    

Follow a short list of guidelines we’ve outlined below to create a perfect usability task that lacks bias. Or check our guide to creating usability testing tasks and questions.

Guidelines for writing usability testing tasks

  1. Create simple realistic tasks – overly complicated tasks will lead to high abandonment rates
  2. Set realistic scenarios – to increase relatability and motivation to complete the task
  3. Use actionable verbs – the task has to encourage a user to carry out an action 
  4. Scenarios must not guide or hint to users on how to complete it – the test will be useless if you tell your testers how to complete it
  5. Leave out unnecessary pieces of information

As mentioned above, task-oriented usability testing is a powerful method when used correctly, especially in combination with pre and post-study questionnaires, think-aloud protocol, and crowd feedback.

Before conducting your first test, we recommend writing a usability testing plan to follow to make sure you don’t forget anything. 

It’s also good to have a working example to follow when writing tasks for your test. We gathered a couple of those to help you out. Choose the usability testing template that fits your needs.

Let’s take a look at mistakes to avoid while writing tasks that make sense for the users, and engage them enough to carry them through your study without boring them to death. This is very important, since giving them non-engaging tasks may create several problems down the road and may create a study in which results are unusable in further research. 

How to write Task Scenarios for Usability Testing

If you’re looking to conduct a task-based usability study, it’s always good to have a working example to follow when writing tasks for your test. We gathered a couple of those to help you out. Choose the usability testing template that fits your needs.

Let’s take a look at mistakes to avoid while writing tasks that make sense for the users, and engage them enough to carry them through your study without boring them to death. This is very important, since giving them non-engaging tasks may create several problems down the road and may create a study in which results are unusable in further research. 

6 Mistakes to avoid when writing task scenarios for usability testing

1. Getting too personal

It is true that you need to understand the tester but be aware of the limitations of your relationship. You are the employer, they are the employee, and you should treat them as such. If you are asking personal questions or setting scenarios involving their loved ones, this could trigger an emotional response in the study participants, resulting in a biased study. Just follow the rule: “Let’s not bring my mother into this.”

Bad example of a study question: You want to get a cake done for your mother’s birthday, buy her a cake.

Good example of a study question: Get your colleague a present, due to her recent promotion

2. Using dummy text to convey real information

Of course, when asking for their address or credit card information, use fake information, but make sure it’s realistic. Maybe you asked for their credit card information multiple times during their study, but if they simply used a fake text like “123,” they might not have noticed that you asked this question several times. Rather, when asking for their credit information use “0123 4567 8910 1112” instead.

Bad example of a study question: Subscribe to our newsletter, use “aaa” as an email address

Good example of a study question: Subscribe to our newsletter, use “jane.dove@foomail.co.uk

3. Being overly specific

You should be creating a scenario, not a checklist for the user to pass. Being too specific in the questions you write may result in robot-like study results, where the participants simply go through the motions. Make the participant think and find the solution themselves, you shouldn’t point them in the right direction up front. Try to write your usability tasks without giving away the correct answer and avoid leading questions.

Poor task example: Use the menu to access “Contact,” then click on the button labeled “Contact Us” and send us a message.

Good example of a study question: Find a way to send us a message.

4. Keep it clear and simple

Scenarios need to be believable and need to reflect the situation the users would find themselves in. Let’s not add more information that would overwhelm the participant. Just ask the users to do what you need them to do, give a little bit of a perspective, provide context, and call it a day.

Bad example of a study question: You have been very interested in our newsletter recently because our product is superior to our competitors. Please fill out the form to subscribe to our newsletter.

Good example of a study question: You took interest in our newsletter, please subscribe to it.

5. Using your studies as a marketing tool

While on the topic of keeping to the point. For the love of all that’s holy, try to not bring marketing to your studies. Marketing-speak is a bunch of pretty words with no additional meaning or information. Use the user’s language. Marketing, which is highly based on emotions, should not be present in your qualitative, or quantitative research. These are two separate entities, and should not be mixed.

Bad example of a study question: Take a look at our newest featured product and transcribe its endless possibilities. 

Good example of a study question: Find the most recent addition to our product line, and repeat the positives stated on the page.

6. Asking about the future

The future is uncertain, you never know what will happen in the future, you might be rich, broke, or dead. Asking about the future will bring skewed results, therefore ask more about the past, or the present, rather than the future. 

Bad example of a study question: Would you buy this product? 

Good example of a study question: Do you have any prior experience with a product similar to ours?
