Usability Testing Guide: What It Is, How to Run It, and When to Use Each Method

Co-authored by Brandon Dorn, UX designer at Viget.As user experience designers, making sure that websites and tools are usable is a critical component of our work, and conducting user research enables us to assess whether we’re achieving that goal or not. Even if we want to incorporate research, however, certain constraints may stand in our way.

‍

A few years ago, we realized that we were facing this issue at Viget, a digital design agency, and we decided to make an effort to prioritize user research. Almost two years ago, we shared initial thoughts on our progress in this blog post. We’ve continued to learn and grow as researchers since then and hope that what we’ve learned along the way can help your clients and coworkers understand the value of research and become better practitioners. Below are some of those lessons.

‍

Make research a priority for your organization

‍

Before you can do more research, it needs to be prioritized across your entire organization — not just within your design team. To that end, you should:

‍

• Know what you’re trying to achieve. By defining specific goals, you can share a clear message with the broader organization about what you’re after, how you can achieve those goals, and how you will measure success. At Viget, we shared our research goals with everyone at the company. In addition, we talked to the business development and project management teams in more depth about specific ways that they could help us achieve our goals, since they have the greatest impact on our ability to do more research.

• Track your progress. Once you’ve made research a priority, make sure to review your goals on an ongoing basis to ensure that you’re making progress and share your findings with the organization. Six months after the research group at Viget started working on our goals, we held a retrospective to figure out what was working — and what wasn’t.
• Adjust your approach as needed. You won’t achieve your goals overnight. As you put different tactics into action, adjust your approach if something isn’t helping you achieve your goals. Be willing to experiment and don’t feel bad if a specific tactic isn’t successful.

‍

Educate your colleagues and clients

‍

If you want people within your organization to get excited about doing more research, they need to understand what research means. To educate your colleagues and clients, you should:

• Explain the fundamentals of research. If someone has not conducted research before, they may not be familiar or feel comfortable with the vernacular. Provide an overview of the fundamental terminology to establish a basic level of understanding. In a blog post, Speaking the Same Language About Research, we outline how we established a common vocabulary at Viget.
• Help others understand the landscape of research methods. As designers, we feel comfortable talking about different methodologies and forget that that information will be new to many people. Look for opportunities to increase understanding by sharing your knowledge. At Viget, we make this happen in several ways. Internally, we give presentations to the company, organize group viewing sessions for webinars about user research, and lead focused workshops to help people put new skills into practice. Externally, we talk about our services and share knowledge through our blog posts. We are even hosting a webinar about conducting user interviews in November and we'd love for you to join us.
• Incorporate others into the research process. Don't just tell people what research is and why it's important — show them. Look for opportunities to bring more people into the research process. Invite people to observe sessions so they can experience research firsthand or have them take on the role of the notetaker. Another simple way to make people feel involved is to share findings on an ongoing basis rather than providing a report at the end of the process.

‍

Broaden your perspective while refining your skill set

‍

Our commitment to testing assumptions led us to challenge ourselves to do research on every project. While we're dogmatic about this goal, we're decidedly un-dogmatic about the form our research takes from one project to another. To pursue this goal, we seek to:

• Expand our understanding. To instill a culture of research at Viget, we've found it necessary to question our assumptions about what research looks like. Books like Erika Hall’s Just Enough Research teach us the range of possible approaches for getting useful user input at any stage of a project, and at any scale. Reflect on any methodological biases that have become well-worn paths in your approach to research. Maybe your organization is meticulous about metrics and quantitative data, and could benefit from a series of qualitative studies. Maybe you have plenty of anecdotal and qualitative evidence about your product that could be better grounded in objective analysis. Aim to establish a balanced perspective on your product through a diverse set of research lenses, filling in gaps as you learn about new approaches.
• Adjust our approach to project constraints. We've found that the only way to consistently incorporate research in our work is to adjust our approach to the context and constraints of any given project. Client expectations, project type, business goals, timelines, budget, and access to participants all influence the type, frequency, and output of our research. Iterative prototype testing of an email editor, for example, looks very different than post-launch qualitative studies for an editorial website. While some projects are research-intensive, short studies can also be worthwhile.
• Reflect on successes and shortcomings. We have a longstanding practice of holding post-project team retrospectives to reflect on and document lessons for future work. Research has naturally come up in these conversations, and many of the things we've discussed you're reading right now. As an agency with a diverse set of clients, it's been important for us to understand what types of research work for what types of clients, and when. Make sure to take time to ask these questions after projects. Mid-project retrospectives can be beneficial, especially on long engagements, yet it's hard to see the forest when you're in the weeds.

‍

Streamline qualitative research processes 🚄

‍

Learning to be more efficient at planning, conducting, and analyzing research has helped us overturn the idea that some projects merit research while others don't. Remote moderated usability tests are one of our preferred methods, yet, in our experience, the biggest obstacle to incorporating these tests isn't the actual moderating or analyzing, but the overhead of acquiring and scheduling participants. While some agencies contract out the work of recruiting, we've found it less expensive and more reliable to collaborate with our clients to find the right people for our tests. That said, here are some recommendations for holding efficient qualitative tests:

• Know your tools ahead of time. We use a number of tools to plan, schedule, annotate, and analyze qualitative tests (we're inveterate spreadsheet users). Learn your tools beforehand, especially if you're trying something new. Tools should fade into the background during tests, which Reframer does nicely.
• Establish a recruiting process. When working with clients to find participants, we'll often provide an email template tailored to the project for them to send to existing or potential users of their product. This introductory email will contain a screener that asks a few project-related demographic or usage questions, and provides us with participant email addresses which we use to follow-up with a link to a scheduling tool. Once this process is established, the project manager will ensure that the UX designer on the team has a regular flow of participants. The recruiting process doesn't take care of itself – participants cancel, or reschedule, or sometimes don't respond at all – yet establishing an approach ahead of time allows you, the researcher, to focus on the research in the midst of the project.
• Start recruiting early. Don't wait until you've finished writing a testing script to begin recruiting participants. Once you determine the aim and focal points of your study, recruit accordingly. Scripts can be revised and approved in the meantime.

‍

Be proactive about making research happen 🤸

‍

As a generalist design agency, we work with clients whose industries and products vary significantly. While some clients come to us with clear research priorities in mind, others treat it as an afterthought. Rare, however, is the client who is actively opposed to researching their product. More often than not, budget and timelines are the limiting factors. So we try not to make research an ordeal, but instead treat it as part of our normal process even if a client hasn't explicitly asked for it. Common-sense perspectives like Jakob Nielsen’s classic “Discount Usability for the Web” remind us that some research is always better than none, and that some can still be meaningfully pursued. We aren’t pushy about research, of course, but instead try to find a way to make it happen when it isn't a definite priority.

‍

‍World Usability Day is coming up on November 9, so now is a great time to stop and reflect on how you approach research and to brainstorm ways to improve your process. The tips above reflect some of the lessons we’ve learned at Viget as we’ve tried to improve our own process. We’d love to hear about approaches you’ve used as well.

In UX research we are told again and again that to ensure truly user-centered design, it’s important to test ideas with real users as early as possible. There are many benefits that come from introducing the voice of the people you are designing for in the early stages of the design process. The more feedback you have to work with, the more you can inform your design to align with real needs and expectations. In turn, this leads to better experiences that are more likely to succeed in the real world.It is not surprising then that paper prototypes have become a popular tool used among researchers. They allow ideas to be tested as they emerge, and can inform initial designs before putting in the hard yards of building the real thing. It would seem that they’re almost a no-brainer for researchers, but just like anything out there, along with all the praise, they have also received a fair share of criticism, so let’s explore paper prototypes a little further.

‍

What’s a paper prototype anyway? 🧐📖

‍

Paper prototyping is a simple usability testing technique designed to test interfaces quickly and cheaply. A paper prototype is nothing more than a visual representation of what an interface could look like on a piece of paper (or even a whiteboard or chalkboard). Unlike high-fidelity prototypes that allow for digital interactions to take place, paper prototypes are considered to be low-fidelity, in that they don’t allow direct user interaction. They can also range in sophistication, from a simple sketch using a pen and paper to simulate an interface, through to using designing or publishing software to create a more polished experience with additional visual elements.

‍

‍

‍

Showing a research participant a paper prototype is far from the real deal, but it can provide useful insights into how users may expect to interact with specific features and what makes sense to them from a basic, user-centered perspective. There are some mixed attitudes towards paper prototypes among the UX community, so before we make any distinct judgements, let's weigh up their pros and cons.

‍

Advantages 🏆

‍

• They’re cheap and fastPen and paper, a basic word document, Photoshop. With a paper prototype, you can take an idea and transform it into a low-fidelity (but workable) testing solution very quickly, without having to write code or use sophisticated tools. This is especially beneficial to researchers who work with tight budgets, and don’t have the time or resources to design an elaborate user testing plan.
• Anyone can do itPaper prototypes allow you to test designs without having to involve multiple roles in building them. Developers can take a back seat as you test initial ideas, before any code work begins.
• They encourage creativityFrom both the product teams participating in their design, but also from the users. They require the user to employ their imagination, and give them the opportunity express their thoughts and ideas on what improvements can be made. Because they look unfinished, they naturally invite constructive criticism and feedback.
• They help minimize your chances of failurePaper prototypes and user-centered design go hand in hand. Introducing real people into your design as early as possible can help verify whether you are on the right track, and generate feedback that may give you a good idea of whether your idea is likely to succeed or not.

‍

Disadvantages 😬

‍

• They’re not as polished as interactive prototypesIf executed poorly, paper prototypes can appear unprofessional and haphazard. They lack the richness of an interactive experience, and if our users are not well informed when coming in for a testing session, they may be surprised to be testing digital experiences on pieces of paper.
• The interaction is limitedDigital experiences can contain animations and interactions that can’t be replicated on paper. It can be difficult for a user to fully understand an interface when these elements are absent, and of course, the closer the interaction mimics the final product, the more reliable our findings will be.
• They require facilitationWith an interactive prototype you can assign your user tasks to complete and observe how they interact with the interface. Paper prototypes, however, require continuous guidance from a moderator in communicating next steps and ensuring participants understand the task at hand.
• Their results have to be interpreted carefullyPaper prototypes can’t emulate the final experience entirely. It is important to interpret their findings while keeping their limitations in mind. Although they can help minimize your chances of failure, they can’t guarantee that your final product will be a success. There are factors that determine success that cannot be captured on a piece of paper, and positive feedback at the prototyping stage does not necessarily equate to a well-received product further down the track.

Improving the interface of card sorting, one prototype at a time 💡

‍

We recently embarked on a research project looking at the user interface of our card-sorting tool, OptimalSort. Our research has two main objectives — first of all to benchmark the current experience on laptops and tablets and identify ways in which we can improve the current interface. The second objective is to look at how we can improve the experience of card sorting on a mobile phone.

‍

Rather than replicating the desktop experience on a smaller screen, we want to create an intuitive experience for mobiles, ensuring we maintain the quality of data collected across devices.Our current mobile experience is a scaled down version of the desktop and still has room for improvement, but despite that, 9 per cent of our users utilize the app. We decided to start from the ground up and test an entirely new design using paper prototypes. In the spirit of testing early and often, we decided to jump right into testing sessions with real users. In our first testing sprint, we asked participants to take part in two tasks. The first was to perform an open or closed card sort on a laptop or tablet. The second task involved using paper prototypes to see how people would respond to the same experience on a mobile phone.

‍

‍

Context is everything 🎯

‍

What did we find? In the context of our research project, paper prototypes worked remarkably well. We were somewhat apprehensive at first, trying to figure out the exact flow of the experience and whether the people coming into our office would get it. As it turns out, people are clever, and even those with limited experience using a smartphone were able to navigate and identify areas for improvement just as easily as anyone else. Some participants even said they prefered the experience of testing paper prototypes over a laptop. In an effort to make our prototype-based tasks easy to understand and easy to explain to our participants, we reduced the full card sort to a few key interactions, minimizing the number of branches in the UI flow.

‍

This could explain a preference for the mobile task, where we only asked participants to sort through a handful of cards, as opposed to a whole set.The main thing we found was that no matter how well you plan your test, paper prototypes require you to be flexible in adapting the flow of your session to however your user responds. We accepted that deviating from our original plan was something we had to embrace, and in the end these additional conversations with our participants helped us generate insights above and beyond the basics we aimed to address. We now have a whole range of feedback that we can utilize in making more sophisticated, interactive prototypes.

‍

Whether our success with using paper prototypes was determined by the specific setup of our testing sessions, or simply by their pure usefulness as a research technique is hard to tell. By first performing a card sorting task on a laptop or tablet, our participants approached the paper prototype with an understanding of what exactly a card sort required. Therefore there is no guarantee that we would have achieved the same level of success in testing paper prototypes on their own. What this does demonstrate, however, is that paper prototyping is heavily dependent on the context of your assessment.

‍

Final thoughts 💬

‍

Paper prototypes are not guaranteed to work for everybody. If you’re designing an entirely new experience and trying to describe something complex in an abstracted form on paper, people may struggle to comprehend your idea. Even a careful explanation doesn’t guarantee that it will be fully understood by the user. Should this stop you from testing out the usefulness of paper prototypes in the context of your project? Absolutely not.

‍

In a perfect world we’d test high fidelity interactive prototypes that resemble the real deal as closely as possible, every step of the way. However, if we look at testing from a practical perspective, before we can fully test sophisticated designs, paper prototypes provide a great solution for generating initial feedback.In his article criticizing the use of paper prototypes, Jake Knapp makes the point that when we show customers a paper prototype we’re inviting feedback, not reactions. What we found in our research however, was quite the opposite.

‍

In our sessions, participants voiced their expectations and understanding of what actions were possible at each stage, without us having to probe specifically for feedback. Sure we also received general comments on icon or colour preferences, but for the most part our users gave us insights into what they felt throughout the experience, in addition to what they thought.

User experience research is super important to developing a product that truly engages, compels and energises people. We all want a website that is easy to navigate, simple to follow and compels our users to finish their tasks. Or an app that supports and drives engagement.

‍

We’ve talked a lot about the various types of research tools that help improve these outcomes. 

‍

There is a rising research trend in 2021.

‍

Mixed method research - what is more compelling than these user research quantitative tools? Combining these with awesome qualitative research! Asking the same questions in various ways can provide deeper insights into how our users think and operate. Empowering you to develop products that truly talk to your users, answer their queries or even address their frustrations.

‍

Though it isn’t enough to simply ‘do research’, as with anything you need to approach it with strategy, focus and direction. This will funnel your time, money and energy into areas that will generate the best results.

‍

Mixed Method UX research is the research trend of 2021

‍

With the likes of Facebook, Amazon, Etsy, eBay, Ford and many more big organizations offering newly formed job openings for mixed methods researchers it becomes very obvious where the research trend is heading.

‍

It’s not only good to have, but now becoming imperative, to gather data, dive deeper and generate insights that provide more information on our users than ever before. And you don't need to be Facebook to reap the benefits. Mixed method research can be implemented across the board and can be as narrow as finding out how your homepage is performing through to analysing in depth the entirety of your product design.

‍

And with all of these massive organizations making the move to increase their data collection and research teams. Why wouldn’t you?

‍

The value in mixed method research is profound. Imagine understanding what, where, how and why your customers would want to use your service. And catering directly for them. The more we understand our customers, the deeper the relationship and the more likely we are to keep them engaged.

‍

Although of course by diving deep into the reasons our users like (or don’t like) how our products operate can drive your organization to target and operate better at a higher level. Gearing your energies to attracting and keeping the right type of customer, providing the right level of service and after care. Potentially reducing overheads, by not delivering to expected levels.

‍

What is mixed method research?

‍

Mixed methods research isn’t overly complicated, and doesn’t take years for you to master. It simply is a term used to refer to using a combination of quantitative and qualitative data. This may mean using a research tool such as card sorting alongside interviews with users. 

‍

Quantitative research is the tangible numbers and metrics that can be gathered through user research such as card sorting or tree testing.

‍

Qualitative research is research around users’ behaviour and experiences. This can be through usability tests, interviews or surveys.

‍

For instance you may be asking ‘how should I order the products on my site?’. With card sorting you can get the data insights that will inform how a user would like to see the products sorted. Coupled with interviews you will get the why.

‍

Understanding the thinking behind the order, and why one user likes to see gym shorts stored under shorts and another would like to see them under active wear. With a deeper understanding of how and why users decide how content should be sorted are made will create a highly intuitive website. 

‍

Another great reason for mixed method research would be to back up data insights for stakeholders. With a depth and breadth of qualitative and quantitative research informing decisions, it becomes clearer why changes may need to be made, or product designs need to be challenged.

‍

How to do mixed method research

‍

Take a look at our article for more examples of the uses of mixed method research. 

‍

Simply put mixed method research means coupling quantitative research, such as tree testing, card sorting or first click testing, with qualitative research such as surveys, interviews or diary entry.

‍

Say, for instance, the product manager has identified that there is an issue with keeping users engaged on the homepage of your website. We would start with asking where they get stuck, and when they are leaving.

‍

This can be done using a first-click tool, such as Chalkmark, which will map where users head when they land on your homepage and beyond. 

‍

This will give you the initial qualitative data. However, it may only give you some of the picture. Coupled with qualitative data, such as watching (and reporting on) body language. Or conducting interviews with users directly after their experience so we can understand why they found the process confusing or misleading.

‍

A fuller picture, means a better understanding.

‍

Key is to identify what your question is and honing in on this through both methods. Ultimately, we are answering your question from both sides of the coin.

‍

Upcoming research trends to watch

‍

Keeping an eye on the progression of the mixed method research trend, will mean keeping an eye on these:

‍

1. Integrated Surveys

‍

Rather than thinking of user surveys as being a one time, in person event, we’re seeing more and more often surveys being implemented through social media, on websites and through email. This means that data can be gathered frequently and across the board. This longitude data allows organizations to continuously analyse, interpret and improve products without really ever stopping. 

‍

Rather than relying on users' memories for events and experiences data can be gathered in the moment. At the time of purchase or interaction. Increasing the reliability and quality of the data collected. 

‍

2. Return to the social research

‍

Customer research is rooted in the focus group. The collection of participants in one space, that allows them to voice their opinions and reach insights collectively. This did used to be an overwhelming task with days or even weeks to analyse unstructured forums and group discussions.

‍

However, now with the advent of online research tools this can also be a way to round out mixed method research.

‍

3. Co-creation

‍

The ability to use your customers input to build better products. This has long been thought a way to increase innovative development. Until recently it too has been cumbersome and difficult to wrangle more than a few participants. But, there are a number of resources in development that will make co-creation the buzzword of the decade.

‍

4. Owned Panels & Community

‍

Beyond community engagement in the social sphere. There is a massive opportunity to utilise these engaged users in product development. Through a trusted forum, users are far more likely to actively and willingly participate in research. Providing insights into the community that will drive stronger product outcomes.

‍

What does this all mean for me

‍

So, there is a lot to keep in mind when conducting any effective user research. And there are a lot of very compelling reasons to do mixed method research and do it regularly. 

‍

To remain innovative, and ahead of the ball it remains very important to be engaged with your users and their needs. Using qualitative and qualitative research to inform product decisions means you can operate knowing a fuller picture.

‍

One of the biggest challenges with user research can be the coordination and participant recruitment. That’s where we come in.

‍

Taking the pain out of the process and streamlining your research. Take a look at our Qualitative Research option, Reframer. Giving you an insight into how we can help make your mixed method research easier and analyse your data efficiently and in a format that is easy to understand.

‍

User research doesn’t need to take weeks or months. With our participant recruitment we can provide reliable and quality participants across the board that will provide data you can rely on.
