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

Hi, I’m Martin. I work as a UX researcher at Trade Me having left Optimal Experience (Optimal Workshop's sister company) last year. For those of you who don’t know, Trade Me is New Zealand’s largest online auction site that also lists real estate to buy and rent, cars to buy, jobs listings, travel accommodation and quite a few other things besides. Over three quarters of the population are members and about three quarters of the Internet traffic for New Zealand sites goes to the sites we run.

‍

Leaving a medium-sized consultancy and joining Trade Me has been a big change in many ways, but in others not so much, as I hadn’t expected to find myself operating in a small team of in-house consultants. The approach the team is taking is proving to be pretty effective, so I thought I’d share some of the details of the way we work with the readers of Optimal Workshop’s blog. Let me explain what I mean…

‍

What agile at Trade Me looks like

‍

Over the last year or so, Trade Me has moved all of its development teams over to Agile following a model pioneered by Spotify. All of the software engineering parts of the business have been ‘squadified’. These people produce the websites & apps or provide and support the infrastructure that makes everything possible.Across Squads, there are common job roles in ‘Chapters’ (like designers or testers) and because people are not easy to force into boxes, and why should they be, there are interest groups called ‘Guilds’.The squads are self-organizing, running their own processes and procedures to get to where they need to. In practice, this means they use as many or as few of the Kanban, Scrum, and Rapid tools they find useful. Over time, we’ve seen that squads tend to follow similar practices as they learn from each other.

‍

How our UX team fits in

‍

Our UX team of three sits outside the squads, but we work with them and with the product owners across the business.How does this work? It might seem counter-intuitive to have UX outside of the tightly-integrated, highly-focused squads, sometimes working with product owners working on stuff that might have little to do with what’s being currently developed in the squads. This comes down to the way Trade Me divides down the UX responsibilities within the organization. Within each squad there is a designer. He or she is responsible for how that feature or app looks, and, more importantly, how it acts — interaction design as well as visual design.Then what do we do, if we are the UX team?

‍

We represent the voice of Trade Me’s users

‍

By conducting research with Trade Me’s users we can validate the squads’ day-to-day decisions, and help frame decisions on future plans. We do this by wearing two hats. Wearing the pointy hats of structured, detailed researchers, we look into long-term trends: the detailed behaviours and goals of our different audiences. We’ve conducted lots of one-on-one interviews with hundreds of people, including top sellers, motor parts buyers, and job seekers, as well as running surveys, focus groups and user testing sessions of future-looking prototypes. For example, we recently spent time with a number of buyers and sellers, seeking to understand their motivations and getting under their skin to find out how they perceive Trade Me.

‍

This kind of research enables Trade Me to anticipate and respond to changes in user perception and satisfaction.Swapping hats to an agile beanie (and stretching the metaphor to breaking point), we react to the medium-term, short-term and very short-term needs of the squads testing their ideas, near-finished work and finished work with users, as well as sometimes simply answering questions and providing opinion, based upon our research. Sometimes this means that we can be testing something in the afternoon having only heard we are needed in the morning. This might sound impossible to accommodate, but the pace of change at Trade Me is such that stuff is getting deployed pretty much every day, many of which affects our users directly. It’s our job to ensure that we support our colleagues to do the very best we can for our users.

‍

How our ‘drop everything’ approach works in practice

‍

‍

We recently conducted five or six rounds (no one can quite remember, we did it so quickly) of testing of our new iPhone application (pictured above) — sometimes testing more than one version at a time. The development team would receive our feedback face-to-face, make changes and we’d be testing the next version of the app the same or the next day. It’s only by doing this that we can ensure that Trade Me members will see positive changes happening daily rather than monthly.

‍

How we prioritize what needs to get done

‍

To help us try to decide what we should be doing at any one time we have some simple rules to prioritise:

• Core product over other business elements
• Finish something over start something new
• Committed work over non-committed work
• Strategic priorities over non-strategic priorities
• Responsive support over less time-critical work
• Where our input is crucial over where our input is a bonus

‍

Applying these rules to any situation makes the decision whether to jump in and help pretty easy.At any one time, each of us in the UX team will have one or more long-term projects, some medium-term projects, and either some short-term projects or the capacity for some short-term projects (usually achieved by putting aside a long-term project for a moment).

‍

We manage our time and projects on Trello, where we can see at a glance what’s happening this and next week, and what we’ve caught sniff of in the wind that might be coming up, or definitely is coming up.On the whole, both we and the squads favour fast response, bulleted list, email ‘reports’ for any short-term requests for user testing.  We get a report out within four hours of testing (usually well within that). After all, the squads are working in short sprints, and our involvement is often at the sharp end where delays are not welcome. Most people aren’t going to read past the management summary anyway, so why not just write that, unless you have to?

‍

How we share our knowledge with the organization

Even though we mainly keep our reporting brief, we want the knowledge we’ve gained from working with each squad or on each product to be available to everyone. So we maintain a wiki that contains summaries of what we did for each piece of work, why we did it and what we found. Detailed reports, if there are any, are attached. We also send all reports out to staff who’ve subscribed to the UX interest email group.

‍

Finally, we send out a monthly email, which looks across a bunch of research we’ve conducted, both short and long-term, and draws conclusions from which our colleagues can learn. All of these latter activities contribute to one of our key objectives: making Trade Me an even more user-centred organization than it is.I’ve been with Trade Me for about six months and we’re constantly refining our UX practices, but so far it seems to be working very well.Right, I’d better go – I’ve just been told I’m user testing something pretty big tomorrow and I need to write a test script!

When it comes to financial services, user experience goes way beyond just making things easy to use. It’s about creating a seamless journey and establishing trust at every touchpoint. Think about it: as we rely more and more on digital banking and financial apps in our everyday lives, we need to feel absolutely confident that our personal information is safe and that the companies managing our money actually know what they're doing. Without that trust foundation, even the most competitive brands will struggle with customer adoption.

‍

Why Trust Matters More Than Ever

‍

The stakes are uniquely high in financial UX. Unlike other digital products where a poor experience might result in minor frustration, financial applications handle our life savings, investment portfolios, and sensitive personal data. A single misstep in design can trigger alarm bells for users, potentially leading to lost customers.

‍

Using UX Research to Measure and Build Trust

‍

Building high trust experiences requires deep insights into user perceptions, behaviors, and pain points. The best UX platforms can help financial companies spot trust issues and test whether their solutions actually work.

‍

Identify Trust Issues with Tree Testing

‍

Tree testing helps financial institutions understand how easily users can find critical information and features:

‍

• Test information architecture to ensure security features and privacy information are easily discoverable
• Identify confusing terminology that may undermine user confidence
• Compare findability metrics for trust-related content across different user segments

‍

Optimize for Trustworthy First Impressions with First-Click Testing

‍

First-click testing helps identify where users naturally look for visual symbols and cues that are associated with security:

‍

• Test where users instinctively look for security indicators like references to security certifications
• Compare the effectiveness of different visual trust symbols (locks, shields, badges)
• Identify the optimal placement for security messaging across key screens

‍

Map User Journeys with Card Sorting

‍

Card sorting helps brands understand how users organize concepts. Reducing confusion, helps your financial brand appear more trustworthy, quickly:

‍

• Use open card sorts to understand how users naturally categorize security and privacy features
• Identify terminology that resonates with users' perceptions around security

‍

Qualitative Insights Through Targeted Questions

‍

Gathering qualitative data through strategically placed questions allows financial institutions to collect rich, timely insights about how much their customers trust their brand:

‍

• Ask open ended questions about trust concerns at key moments in the testing process
• Gather specific feedback on security terminology understanding and recognition
• Capture emotional responses to different trust indicators

‍

What Makes a Financial Brand Look Trustworthy?

‍

Visual Consistency and Professional Polish

‍

When someone opens your financial app or website, they're making snap judgments about whether they can trust you with their money. It happens in milliseconds, and a lot of that decision comes down to how polished and consistent everything looks.Clean, consistent design sends that signal of stability and attention to detail that people expect when money's involved.

‍

To achieve this, develop and rigorously apply a solid design system across all digital touchpoints including fonts, colors, button styles, and spacing, it all needs to be consistent across every page and interaction. Even small inconsistencies can make people subconsciously lose confidence.

‍

Making Security Visible

‍

Unlike walking into a bank where you can see the vault and security cameras, digital security happens behind the scenes. Users can't see all the protection you've built in unless you make a point of showing them.

‍

Highlighting your security measures in ways that feel reassuring rather than overwhelming gives people that same sense of "my money is safe here" that they'd get from seeing a bank's physical security.

‍

From a design perspective, apply this thinking to elements like:

‍

• Real time login notifications
• Transaction verification steps
• Clear encryption indicators
• Transparent data usage explanations
• Session timeout warnings

‍

You can test the success of these design elements through preference testing, where you can compare different approaches to security visualization to determine which elements most effectively communicate trust without creating anxiety.

‍

Making Complex Language Simple

‍

Financial terminology is naturally complex, but your interface content doesn't have to be. Clear, straightforward language builds trust so it’s important to develop a content strategy that:

‍

• Explains unavoidable complex terms contextually
• Replaces jargon with plain language
• Provides proactive guidance before errors occur
• Uses positive, confident messaging around security features

‍

You can test your language and navigation elements by using tree testing to evaluate user understanding of different terminology, measuring success rates for finding information using different labeling options.

‍

Create an Ongoing Trust Measurement Program

‍

A user research platform enables financial institutions to implement ongoing trust measurement across the product lifecycle:

‍

Establish Trust Benchmarks

‍

Use UX research tools to establish baseline metrics for measuring user trust:

‍

• Findability scores for security features
• User reported confidence ratings
• Success rates for security related tasks
• Terminology comprehension levels

‍

Validate Design Updates

‍

Before implementing changes to critical elements, use quick tests to validate designs:

‍

• Compare current vs. proposed designs with prototype testing
• Measure findability improvements with tree testing
• Evaluate usability through first-click testing

‍

Monitor Trust Metrics Over Time

‍

Create a dashboard of trust metrics that can be tracked regularly:

‍

• Task success rates for security related activities
• Time-to-completion for verification processes
• Confidence ratings at key security touchpoints

‍

Cross-Functional Collaboration to Improve Trust

‍

While UX designers can significantly impact brand credibility, remember that trust is earned across the entire customer experience:

‍

• Product teams ensure feature promises align with actual capabilities
• Security teams translate complex security measures into user-friendly experiences
• Marketing ensures brand promises align with the actual user experience
• ‍Customer service supports customers when trust issues arise

‍

Trust as a Competitive Advantage

‍

In an industry where products and services can often seem interchangeable to consumers, trust becomes a powerful differentiator. By placing trust at the center of your design philosophy and using comprehensive user research to measure and improve trust metrics, you're not just improving user experience, you're creating a foundation for lasting customer relationships in an industry where loyalty is increasingly rare.

‍

The most successful financial institutions of the future won't necessarily be those with the most features or the slickest interfaces, but those that have earned and maintained user trust through thoughtful UX design built on a foundation of deep user research and continuous improvement.

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.
