5 ways to measure UX return on investment

Return on investment (ROI) is often the term on everyone’s lips when starting a big project or even when reviewing a website. It’s especially popular with those that hold the purse strings.  As UX researchers it is important to consider the ROI of the work we do and understand how to measure this. 

We’ve lined up 5 key ways to measure ROI for UX research to help you get the conversation underway with stakeholders so you can show real and tangible benefits to your organization. 

1. Meet and exceed user expectations

Put simply, a product that meets and exceeds user expectations leads to increased revenue. When potential buyers are able to find and purchase what they’re looking for, easily, they’ll complete their purchase, and are far more likely to come back. The simple fact that users can finish their task will increase sales and improve overall customer satisfaction which has an influence on their loyalty. Repeat business means repeat sales. Means increased revenue.

Creating, developing and maintaining a usable website is more important than you might think. And this is measurable! Tracking and analyzing website performance prior to the UX research and after can be insightful and directly influenced by changes made based on UX research.

Measurable: review the website (product) performance prior to UX research and after changes have been made. The increase in clicks, completed tasks and/or baskets will tell the story.

2. Reduce development time

UX research done at the initial stages of a project can lead to a reduction in development time of by 33% to 50%! And reduced time developing, means reduced costs (people and overheads) and a speedier to market date. What’s not to love? 

Measurable: This one is a little more tricky as you have saved time (and cost) up front. Aiding in speed to market and performance prior to execution. Internal stakeholder research may be of value post the live date to understand how the project went.

3. Ongoing development costs

And the double hitter? Creating a product that has the user in mind up front, reduces the need to rehash or revisit as quickly. Reducing ongoing costs. Early UX research can help with the detection of errors early on in the development process. Fixing errors after development costs a company up to 100 times more than dealing with the same error before development.

Measureable: Again, as UX research has saved time and money up front this one can be difficult to track. Though depending on your organization and previous projects you could conduct internal research to understand how the project compares and the time and cost savings.

4. Meeting user requirements

Did you know that 70% of projects fail due to the lack of user acceptance? This is often because project managers fail to understand the user requirements properly. Thanks to UX research early on, gaining insights into users and only spending time developing the functions users actually want, saving time and reducing development costs. Make sure you get confirmation on those requirements by iterative testing. As always, fail early, fail often. Robust testing up front means that in the end, you’ll have a product that will meet the needs of the user.

Measurable: Where is the product currently? How does it perform? Set a benchmark up front and review post UX research. The deliverables should make the ROI obvious.

5. Investing in UX research leads to an essential competitive advantage.

Thanks to UX research you can find out exactly what your customers want, need and expect from you. This gives you a competitive advantage over other companies in your market. But you should be aware that more and more companies are investing in UX while customers are ever more demanding, their expectations continue to grow and they don’t tolerate bad experiences. And going elsewhere is an easy decision to make.

Measurable: Murky this one, but no less important. Knowing, understanding and responding to competitors can help keep you in the lead, and developing products that meet and exceed those user expectations.

Wrap up

Showing the ROI on the work we do is an essential part of getting key stakeholders on board with our research. It can be challenging to talk the same language, ultimately we all want the same outcome…a product that works well for our users, and delivers additional revenue.

For some continued reading (or watching in this case), Anna Bek, Product and Delivery Manager at Xplor explored the same concept of "How to measure experience" during her UX New Zealand 2020 – watch it here as she shares a perspective on UX ROI.

Usability Experts Unite: The Power of Heuristic Evaluation in User Interface Design

Usability experts play an essential role in the user interface design process by evaluating the usability of digital products from a very important perspective - the users! Usability experts utilize various techniques such as heuristic evaluation, usability testing, and user research to gather data on how users interact with digital products and services. This data helps to identify design flaws and areas for improvement, leading to the development of user-friendly and efficient products.

Heuristic evaluation is a usability research technique used to evaluate the user interface design of a digital product based on a set of ‘heuristics’ or ‘usability principles’. These heuristics are derived from a set of established principles of user experience design - attributed to the landmark article “Improving a Human-Computer Dialogue” published by web usability pioneers Jakob Nielsen and Rolf Molich in 1990. The principles focus on the experiential aspects of a user interface. 

In this article, we’ll discuss what heuristic evaluation is and how usability experts use the principles to create exceptional design. We’ll also discuss how usability testing works hand-in-hand with heuristic evaluation, and how minimalist design and user control impact user experience. So, let’s dive in!

Understanding Heuristic Evaluation


Heuristic evaluation helps usability experts to examine interface design against tried and tested rules of thumb. To conduct a heuristic evaluation, usability experts typically work through the interface of the digital product and identify any issues or areas for improvement based on these broad rules of thumb, of which there are ten. They broadly cover the key areas of design that impact user experience - not bad for an article published over 30 years ago!

The ten principles are:

  1. Prevention error: Well-functioning error messages are good, but instead of messages, can these problems be removed in the first place? Remove the opportunity for slips and mistakes to occur.
  2. Consistency and standards: Language, terms, and actions used should be consistent to not cause any confusion.
  3. Control and freedom for users: Give your users the freedom and control to undo/redo actions and exit out of situations if needed.
  4. System status visibility: Let your users know what’s going on with the site. Is the page they’re on currently loading, or has it finished loading?
  5. Design and aesthetics: Cut out unnecessary information and clutter to enhance visibility. Keep things in a minimalist style.
  6. Help and documentation: Ensure that information is easy to find for users, isn’t too large and is focused on your users’ tasks.
  7. Recognition, not recall: Make sure that your users don’t have to rely on their memories. Instead, make options, actions and objects visible. Provide instructions for use too.
  8. Provide a match between the system and the real world: Does the system speak the same language and use the same terms as your users? If you use a lot of jargon, make sure that all users can understand by providing an explanation or using other terms that are familiar to them. Also ensure that all your information appears in a logical and natural order.
  9. Flexibility: Is your interface easy to use and it is flexible for users? Ensure your system can cater to users to all types, from experts to novices.
  10. Help users to recognize, diagnose and recover from errors: Your users should not feel frustrated by any error messages they see. Instead, express errors in plain, jargon-free language they can understand. Make sure the problem is clearly stated and offer a solution for how to fix it.

Heuristic evaluation is a cost-effective way to identify usability issues early in the design process (although they can be performed at any stage) leading to faster and more efficient design iterations. It also provides a structured approach to evaluating user interfaces, making it easier to identify usability issues. By providing valuable feedback on overall usability, heuristic evaluation helps to improve user satisfaction and retention.

The Role of Usability Experts in Heuristic Evaluation

Usability experts play a central role in the heuristic evaluation process by providing feedback on the usability of a digital product, identifying any issues or areas for improvement, and suggesting changes to optimize user experience.

One of the primary goals of usability experts during the heuristic evaluation process is to identify and prevent errors in user interface design. They achieve this by applying the principles of error prevention, such as providing clear instructions and warnings, minimizing the cognitive load on users, and reducing the chances of making errors in the first place. For example, they may suggest adding confirmation dialogs for critical actions, ensuring that error messages are clear and concise, and making the navigation intuitive and straightforward.

Usability experts also use user testing to inform their heuristic evaluation. User testing involves gathering data from users interacting with the product or service and observing their behavior and feedback. This data helps to validate the design decisions made during the heuristic evaluation and identify additional usability issues that may have been missed. For example, usability experts may conduct A/B testing to compare the effectiveness of different design variations, gather feedback from user surveys, and conduct user interviews to gain insights into users' needs and preferences.

Conducting user testing with users that represent, as closely as possible, actual end users, ensures that the product is optimized for its target audience. Check out our tool Reframer, which helps usability experts collaborate and record research observations in one central database.

Minimalist Design and User Control in Heuristic Evaluation

Minimalist design and user control are two key principles that usability experts focus on during the heuristic evaluation process. A minimalist design is one that is clean, simple, and focuses on the essentials, while user control refers to the extent to which users can control their interactions with the product or service.

Minimalist design is important because it allows users to focus on the content and tasks at hand without being distracted by unnecessary elements or clutter. Usability experts evaluate the level of minimalist design in a user interface by assessing the visual hierarchy, the use of white space, the clarity of the content, and the consistency of the design elements. Information architecture (the system and structure you use to organize and label content) has a massive impact here, along with the content itself being concise and meaningful.

Incorporating minimalist design principles into heuristic evaluation can improve the overall user experience by simplifying the design, reducing cognitive load, and making it easier for users to find what they need. Usability experts may incorporate minimalist design by simplifying the navigation and site structure, reducing the number of design elements, and removing any unnecessary content (check out our tool Treejack to conduct site structure, navigation, and categorization research). Consistent color schemes and typography can also help to create a cohesive and unified design.

User control is also critical in a user interface design because it gives users the power to decide how they interact with the product or service. Usability experts evaluate the level of user control by looking at the design of the navigation, the placement of buttons and prompts, the feedback given to users, and the ability to undo actions. Again, usability testing plays an important role in heuristic evaluation by allowing researchers to see how users respond to the level of control provided, and gather feedback on any potential hiccups or roadblocks.

Usability Testing and Heuristic Evaluation

Usability testing and heuristic evaluation are both important components of the user-centered design process, and they complement each other in different ways.

Usability testing involves gathering feedback from users as they interact with a digital product. This feedback can provide valuable insights into how users perceive and use the user interface design, identify any usability issues, and help validate design decisions. Usability testing can be conducted in different forms, such as moderated or unmoderated, remote or in-person, and task-based or exploratory. Check out our usability testing 101 article to learn more.

On the other hand, heuristic evaluation is a method in which usability experts evaluate a product against a set of usability principles. While heuristic evaluation is a useful method to quickly identify usability issues and areas for improvement, it does not involve direct feedback from users.

Usability testing can be used to validate heuristic evaluation findings by providing evidence of how users interact with the product or service. For example, if a usability expert identifies a potential usability issue related to the navigation of a website during heuristic evaluation, usability testing can be used to see if users actually have difficulty finding what they need on the website. In this way, usability testing provides a reality check to the heuristic evaluation and helps ensure that the findings are grounded in actual user behavior.

Usability testing and heuristic evaluation work together in the design process by informing and validating each other. For example, a designer may conduct heuristic evaluation to identify potential usability issues and then use the insights gained to design a new iteration of the product or service. The designer can then use usability testing to validate that the new design has successfully addressed the identified usability issues and improved the user experience. This iterative process of designing, testing, and refining based on feedback from both heuristic evaluation and usability testing leads to a user-centered design that is more likely to meet user needs and expectations.

Conclusion

Heuristic evaluation is a powerful usability research technique that usability experts use to evaluate digital product interfaces based on a set of established principles of user experience design. After all these years, the ten principles of heuristic evaluation still cover the key areas of design that impact user experience, making it easier to identify usability issues early in the design process, leading to faster and more efficient design iterations. Usability experts play a critical role in the heuristic evaluation process by identifying design flaws and areas for improvement, using user testing to validate design decisions, and ensuring that the product is optimized for its intended users.

Minimalist design and user control are two key principles that usability experts focus on during the heuristic evaluation process. A minimalist design is clean, simple, and focuses on the essentials, while user control gives users the freedom and control to undo/redo actions and exit out of situations if needed. By following these principles, usability experts can create an exceptional design that enhances visibility, reduces cognitive load, and provides a positive user experience. 

Ultimately, heuristic evaluation is a cost-effective way to identify usability issues at any point in the design process, leading to faster and more efficient design iterations, and improving user satisfaction and retention. How many of the ten heuristic design principles does your digital product satisfy?

Making the Complex Simple: Clarity as a UX Superpower in Financial Services

In the realm of financial services, complexity isn't just a challenge, it's the default state. From intricate investment products to multi-layered insurance policies to complex fee structures, financial services are inherently complicated. But your users don't want complexity; they want confidence, clarity, and control over their financial lives.

How to keep things simple with good UX research 

Understanding how users perceive and navigate complexity requires systematic research. Optimal's platform offers specialized tools to identify complexity pain points and validate simplification strategies:

Uncover Navigation Challenges with Tree Testing

Complex financial products often create equally complex navigation structures:

How can you solve this? 

  • Test how easily users can find key information within your financial platform
  • Identify terminology and organizational structures that confuse users
  • Compare different information architectures to find the most intuitive organization

Identify Confusion Points with First-Click Testing

Understanding where users instinctively look for information reveals valuable insights about mental models:

How can you solve this? 

  • Test where users click when trying to accomplish common financial tasks
  • Compare multiple interface designs for complex financial tools
  • Identify misalignments between expected and actual user behavior

Understand User Mental Models with Card Sorting

Financial terminology and categorization often don't align with how customers think:

How can you solve this? 

  • Use open card sorts to understand how users naturally group financial concepts
  • Test comprehension of financial terminology
  • Identify intuitive labels for complex financial products

Practical Strategies for Simplifying Financial UX

1. Progressive Information Disclosure

Rather than bombarding users with all information at once, layer information from essential to detailed:

  • Start with core concepts and benefits
  • Provide expandable sections for those who want deeper dives
  • Use tooltips and contextual help for terminology
  • Create information hierarchies that guide users from basic to advanced understanding

2. Visual Representation of Numerical Concepts

Financial services are inherently numerical, but humans don't naturally think in numbers—we think in pictures and comparisons.

What could this look like? 

  • Use visual scales and comparisons instead of just presenting raw numbers
  • Implement interactive calculators that show real-time impact of choices
  • Create visual hierarchies that guide attention to most relevant figures
  • Design comparative visualizations that put numbers in context

3. Contextual Decision Support

Users don't just need information; they need guidance relevant to their specific situation.

How do you solve for this? 

  • Design contextual recommendations based on user data
  • Provide comparison tools that highlight differences relevant to the user
  • Offer scenario modeling that shows outcomes of different choices
  • Implement guided decision flows for complex choices

4. Language Simplification and Standardization

Financial jargon is perhaps the most visible form of unnecessary complexity. So, what can you do? 

  • Develop and enforce a simplified language style guide
  • Create a financial glossary integrated contextually into the experience
  • Test copy with actual users, measuring comprehension, not just preference
  • Replace industry terms with everyday language when possible

Measuring Simplification Success

To determine whether your simplification efforts are working, establish a continuous measurement program:

1. Establish Complexity Baselines

Use Optimal's tools to create baseline measurements:

  • Success rates for completing complex tasks
  • Time required to find critical information
  • Comprehension scores for key financial concepts
  • User confidence ratings for financial decisions

2. Implement Iterative Testing

Before launching major simplification initiatives, validate improvements through:

  • A/B testing of alternative explanations and designs
  • Comparative testing of current vs. simplified interfaces
  • Comprehension testing of revised terminology and content

3. Track Simplification Metrics Over Time

Create a dashboard of key simplification indicators:

  • Task success rates for complex financial activities
  • Support call volume related to confusion
  • Feature adoption rates for previously underutilized tools
  • User-reported confidence in financial decisions

Where rubber hits the road: Organizational Commitment to Clarity

True simplification goes beyond interface design. It requires organizational commitment at the most foundational level:

  • Product development: Are we creating inherently understandable products?
  • Legal and compliance: Can we satisfy requirements while maintaining clarity?
  • Marketing: Are we setting appropriate expectations about complexity?
  • Customer service: Are we gathering intelligence about confusion points?

When there is a deep commitment from the entire organization to simplification, it becomes part of a businesses’ UX DNA. 

Conclusion: The Future Belongs to the Clear

As financial services become increasingly digital and self-directed, clarity bcomes essential for business success. The financial brands that will thrive in the coming decade won't necessarily be those with the most features or the lowest fees, but those that make the complex world of finance genuinely understandable to everyday users.

By embracing clarity as a core design principle and supporting it with systematic user research, you're not just improving user experience, you're democratizing financial success itself.

5 tips for running an effective usability test

Usability testing is one of the best ways to measure how easy and intuitive to use something is by testing it with real people. You can read about the basics of usability testing here.

Earlier this year, a small team within Optimal Workshop completely redesigned the company blog. More than anything, we wanted to create something that was user-friendly for our readers and would give them a reason to return. I was part of that team, and we ran numerous sessions interviewing regular readers as well as people unfamiliar with our blog. We also ran card sorts, tree tests and other studies to find out all we could about how people search for UX content. Unsurprisingly, one of the most valuable activities we did was usability testing – sitting down with representative users and watching them as they worked through a series of tasks we provided. We asked general questions like “Where would you go to find information about card sorting”, and we also observed them as they searched through our website for learning content.

By stripping away any barriers between ourselves and our users and observing them as they navigated through our website and learning resources, as well as those of other companies, we were able to build a blog with these people’s behaviors and motivations in mind.

Usability testing is an invaluable research method, and every user researcher should be able to run sessions effectively. Here are 5 tips for doing so, in no particular order.

1. Clarify your goals with stakeholders

Never go into a usability test blind. Before you ever sit down with a participant, make sure you know exactly what you want to get out of the session by writing down your research goals. This will help to keep you focused, essentially giving you a guiding light that you can refer back as you go about the various logistical tasks of your research. But you also need to take this a step further. It’s important to make sure that the people who will utilize the results of your research – your stakeholders – have an opportunity to give you their input on the goals as early as possible.

If you’re running usability tests with the aim of creating marketing personas, for example, meet with your organization’s marketing team and figure out the types of information they need to create these personas. In some cases, it’s also helpful to clarify how you plan to gather this data, which can involve explaining some of the techniques you’re going to use.

Lastly, find out how your stakeholders plan to use your findings. If there are a lot of objectives, organize your usability test so you ask the most important questions first. That way, if you end up going off track or you run out of time you’ll have already gathered the most important data for your stakeholders.

2. Be flexible with your questions

A list of pre-prepared questions will help significantly when it comes time to sit down and run your usability testing sessions. But while a list is essential, sometimes it can also pay to ‘follow your nose’ and steer the conversation in a (potentially) more fruitful direction.

How many times have you been having a conversation with a friend over a drink or dinner, only for you both to completely lose track of time and find yourselves discussing something completely unrelated? While it’s not good practice to let your usability testing sessions get off track to this extent, you can surface some very interesting insights by paying close attention to a user’s behavior and answers during a testing session and following interesting leads.

Ideally, and with enough practice, you’ll be able to answer your core (prepared) questions and ask a number of other questions that spring to mind during the session. This is a skill that takes time to master, however.

3. Write a script for your sessions

While a usability test script may sound like a fancy name for your research questions, it’s actually a document that’s much more comprehensive. If you prepare it correctly (we’ll explain how below), you’ll have a document that you can use to capture in-depth insights from your participants.

Here are some of the key things to keep in mind when putting together your script:

  • Write a friendly introduction – It may sound obvious, but taking the time to come up with a friendly, warm introduction will get your sessions off to a much better start. The bonus of writing it down is that you’re far less likely to forget it!
  • Ask to record the session – It’s important to record your session (whether through video or audio), as you’ll want to go back later and analyze any details you may have missed. This means asking for explicit permission to record participants. In addition to making them feel more comfortable, it’s just good practice to do so.
  • Allocate time for the basics – Don’t dive into the complex questions first, use the first few minutes to gather basic data. This could be things like where they work and their familiarity with your organization and/or product.
  • Encourage them to explain their thought process – “I’d like you to explain what you’re doing as you make your way through the task”. This simple request will give you an opportunity to ask follow-up questions that you otherwise may not have thought to ask.
  • Let participants know that they’re not being tested – Whenever a participant steps into the room for a test, they’re naturally going to feel like they’re being tested. Explain that you’re testing the product, not them. It’s also helpful to let them know that there are no right or wrong answers. This is an important step if you want to keep them relaxed.

It’s often easiest to have a document with your script printed out and ready to go for each usability test.

4. Take advantage of software

You’d never see a builder without a toolbox full of a useful assortment of tools. Likewise, software can make the life of a user research that much easier. The paper-based ways of recording information are still perfectly valid, but introducing custom tools can make both the logistics of user research and the actual sessions themselves much easier to manage.

Take a tool like Calendly, for example. This is a powerful piece of scheduling software that almost completely takes over the endless back and forth of scheduling usability tests. Calendly acts as a middle man between you and your participants, allowing you to set the times you’re free to host usability tests, and then allowing participants to choose a session that suits them from these times.

Our very own Reframer makes the task of running usability tests and analyzing insights that much easier. During your sessions, you can use Reframer to take comprehensive notes and apply tags like “positive” or “struggled” to different observations. Then, after you’ve concluded your tests, Reframer’s analysis function will help you understand wider themes that are present across your participants.

There’s another benefit to using a tool like Reframer. Keeping all of your notes in place will mean you easily pull up data from past research sessions whenever you need to.

5. Involve others

Usability tests (and user interviews, for that matter) are a great opportunity to open up research to your wider organization. Whether it’s stakeholders, other members of your immediate team or even members of entirely different departments, giving them the chance to sit down with users will show them how their products are really being used. If nothing else, these sessions will help those within your organization build empathy with the people they’re building products for.

There are quite a few ways to bring others in, such as:

  • To help you set up the research – This can be a helpful exercise for both you (the researcher) and the people you’re bringing in. Collaborate on the overarching research objectives, ask them what types of results they’d like to see and what sort of tasks they think could be used to gather these results.
  • As notetakers – Having a dedicated notetaker will make your life as a researcher significantly easier. This means you’ll have someone to record any interesting observations while you focus on running the session. Just let them know what types of notes you’d like to see.
  • To help you analyze the data – Once you’ve wrapped up your usability testing sessions, bring others in to help analyze the findings. There’s a good chance that an outside perspective will catch something you may miss. Also, if you’re bringing stakeholders into the analysis stage, they'll get a clearer picture of what it means and where the data came from.

There are myriad other tips and best practices to keep in mind when usability testing, many of which we cover in our introductory page. Important considerations include taking good quality notes, carefully managing participants during the session (not giving them too much guidance) and remaining neutral throughout when answering their questions. If you feel like we’ve missed any really important points, feel free to leave a comment!
