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?

From Exposition to Resolution: Looking at User Experience as a Narrative Arc

“If storymapping could unearth patterns and bring together a cohesive story that engages audiences in the world of entertainment and film, why couldn’t we use a similar approach to engage our audiences?’Donna Lichaw and Lis Hubert

User Experience work makes the most sense to me in the context of storytelling. So when I saw Donna Lichaw and Lis Hubert’s presentation on storymapping at edUi recently, it resonated. A user’s path through a website can be likened to the traditional storytelling structure of crisis or conflict, exposition — and even a climax or two.

The narrative arc and the user experience

So just how can the same structure that suits fairytales help us to design a compelling experience for our customers? Well, storyboarding is an obvious example of how UX design and storytelling mesh. A traditional storyboard for a movie or TV episode lays out sequential images to help visualize what the final production will show. Similarly, we map out users' needs and journeys via wireframes, sketches, and journey maps, all the while picturing how people will actually interact with the product.

But the connection between storytelling and the user experience design process goes even deeper than that. Every time a user interacts with our website or product, we get to tell them a story. And a traditional literary storytelling structure maps fairly well to just how users interact with the digital stories we’re telling.Hence Donna and Lis’ conception of storymapping as ‘a diagram that maps out a story using a traditional narrative structure called a narrative arc.’ They concede that while ‘using stories in UX design...is nothing new’, a ‘narrative-arc diagram could also help us to rapidly assess content strengths, weaknesses, and opportunities.’

Storytelling was a common theme at edUI

The edUi conference in Richmond, Virginia brought together an assembly of people who produce websites or web content for large institutions. I met people from libraries, universities, museums, various levels of government, and many other places. The theme of storytelling was present throughout, both explicitly and implicitly.Keynote speaker Matt Novak from Paleofuture talked about how futurists of the past tried to predict the future, and what we can learn from the stories they told. Matthew Edgar discussed what stories our failed content tell — what story does a 404 page tell? Or a page telling users they have zero search results? Two great presentations that got me thinking about storytelling in a different way.

Ultimately, it all clicked for me when I attended Donna and Lis’ presentation ‘Storymapping: A Macguyver Approach to Content Strategy’ (and yes, it was as compelling as the title suggests). They presented a case study of how they applied a traditional narrative structure to a website redesign process. The basic story structure we all learned in school usually includes a pretty standard list of elements. Donna and Lis had tweaked the definitions a bit, and applied them to the process of how users interact with web content.

Points on the Narrative Arc (from their presentation)

narrative arc UX

Exposition — provides crucial background information and often ends with ‘inciting incident’ kicking off the rest of the story

Donna and Lis pointed out that in the context of doing content strategy work, the inciting incident could be the problem that kicks off a development process. I think it can also be the need that brings users to a website to begin with.

Rising Action — Building toward the climax, users explore a website using different approaches

Here I think the analogy is a little looser. While a story can sometimes be well-served by a long and winding rising action, it’s best to keep this part of the process a bit more straightforward in web work. If there’s too much opportunity for wandering, users may get lost or never come back.

Crisis / Climax — The turning point in a story, and then when the conflict comes to a peak

The crisis is what leads users to your site in the first place — a problem to solve, an answer to find, a purchase to make. And to me the climax sounds like the aha! moment that we all aspire to provide, when the user answers their question, makes a purchase, or otherwise feels satisfied from using the site. If a user never gets to this point, their story just peters out unresolved. They’re forced to either begin the entire process again on your site (now feeling frustrated, no doubt), or turn to a competitor.

Falling Action — The story or user interaction starts to wind down and loose ends are tied up

A confirmation of purchase is sent, or maybe the user signs up for a newsletter.

Denouement / Resolution — The end of the story, the main conflict is resolved

The user goes away with a hopefully positive experience, having been able to meet their information or product needs. If we’re lucky, they spread the word to others!Check out Part 2 of Donna and Lis' three-part article on storymapping.  I definitely recommend exploring their ideas in more depth, and having a go at mapping your own UX projects to the above structure.

A word about crises. The idea of a ‘crisis’ is at the heart of the narrative arc. As we know from watching films and reading novels, the main character always has a problem to overcome. So crisis and conflict show up a few times through this process.While the word ‘crisis’ carries some negative connotations (and that clearly applies to visiting a terribly designed site!), I think it can be viewed more generally when we apply the term to user experience. Did your user have a crisis that brought them to your site? What are they trying to resolve by visiting it? Their central purpose can be the crisis that gives rise to all the other parts of their story.

Why storymapping to a narrative arc is good for your design

Mapping a user interaction along the narrative arc makes it easy to spot potential points of frustration, and also serves to keep the inciting incident or fundamental user need in the forefront of our thinking. Those points of frustration and interaction are natural fits for testing and further development.

For example, if your site has a low conversion rate, that translates to users never hitting the climactic point of their story. It might be helpful to look at their interactions from the earlier phases of their story before they get to the climax. Maybe your site doesn’t clearly establish its reason for existing (exposition), or it might be too hard for users to search and explore your content (rising action).Guiding the user through each phase of the structure described above makes it more difficult to skip an important part of how our content is found and used.

We can ask questions like:

  • How does each user task fit into a narrative structure?
  • Are we dumping them into the climax without any context?
  • Does the site lack a resolution or falling action?
  • How would it feel to be a user in those situations?

These questions bring up great objectives for qualitative testing — sitting down with a user and asking them to show us their story.

What to do before mapping to narrative arc

Many sessions at edUi also touched on analytics or user testing. In crafting a new story, we can’t ignore what’s already in place — especially if some of it is appreciated by users. So before we can start storymapping the user journey, we need to analyze our site analytics, and run quantitative and qualitative user tests. This user research will give us insights into what story we’re already telling (whether it’s on purpose or not).

What’s working about the narrative, and what isn’t? Even if a project is starting from scratch on a new site, your potential visitors will bring stories of their own. It might be useful to check stats to see if users leave early on in the process, during the exposition phase. A high bounce rate might mean a page doesn't supply that expositional content in a way that's clear and engaging to encourage further interaction.Looking at analytics and user testing data can be like a movie's trial advance screening — you can establish how the audience/users actually want to experience the site's content.

How mapping to the narrative arc is playing out in my UX practice

Since I returned from edUi, I've been thinking about the narrative structure constantly. I find it helps me frame user interactions in a new way, and I've already spotted gaps in storytelling that can be easily filled in. My attention instantly went to the many forms on our site. What’s the Rising Action like at that point? Streamlining our forms and using friendly language can help keep the user’s story focused and moving forward toward clicking that submit button as a climax.

I’m also trying to remember that every user is the protagonist of their own story, and that what works for one narrative might not work for another. I’d like to experiment with ways to provide different kinds of exposition to different users. I think it’s possible to balance telling multiple stories on one site, but maybe it’s not the best idea to mix exposition for multiple stories on the same page.And I also wonder if we could provide cues to a user that direct them to exposition for their own inciting incident...a topic for another article perhaps.What stories are you telling your users? Do they follow a clear arc, or are there rough transitions? These are great questions to ask yourself as you design experiences and analyze existing ones. The edUi conference was a great opportunity to investigate these ideas, and I can’t wait to return next year.

Welcome to our latest addition: Prototype testing 🐣

Today, we’re thrilled to announce the arrival of the latest member of the Optimal family:  Prototype Testing! This exciting and much-requested new tool allows you to test designs early and often with users to gather fast insights, and make confident design decisions to create more intuitive and user-friendly digital experiences. 

Optimal gives you tools you need to easily build a prototype to test using images and screens and creating clickable areas, or you can import a prototype from Figma and get testing. The first iteration of prototype testing is an open beta, and we’ll be working closely with our customers and community to gather feedback and ideas for further improvements in the months to come.

When to use prototype testing 

Prototype testing is a great way to validate design ideas, identify usability issues, and gather feedback from users before investing too heavily in the development of products, websites, and apps. To further inform your insights, it’s a good idea to include sentiment questions or rating scales alongside your tasks.

Early in the design process: Test initial ideas and concepts to gauge user reactions and feelings about your conceptual solutions. 

Iterative design phases: Continuously test and refine prototypes as you make changes and improvements to the designs. 

Before major milestones: Validate designs before key project stages, such as stakeholder reviews or final approvals.

Usability Testing: Conduct summative research to assess a design's overall performance and gauge real user feedback to guide future design decisions and enhancements.

How it works 🧑🏽‍💻

No existing prototype? No problem. We've made it easy to create one right within Optimal. Here's how:

  1. Import your visuals

Start by uploading a series of screenshots or images that represent your design flow. These will form the backbone of your prototype.

  1. Create interactive elements

Once your visuals are in place, it's time to bring them to life. Use our intuitive interface to designate clickable areas on each screen. These will act as navigation points for your test participants.

  1. Set up the flow

Connect your screens in a logical sequence, mirroring the user journey you want to test. This creates a seamless, interactive experience for your participants.

  1. Preview and refine

Before launching your study, take a moment to walk through your prototype. Ensure all clickable areas work as intended and the flow feels natural.

The result? A fully functional prototype that looks and feels like a real digital product. Your test participants will be able to navigate through it just as they would a live website or app, providing you with authentic, actionable insights.

By empowering you to build prototypes from scratch, we're removing barriers to early-stage testing. This means you can validate ideas faster, iterate with confidence, and ultimately deliver better digital experiences.

Or…import your prototypes directly from Figma 

There’s a bit of housekeeping you’ll need to do in Figma in order to provide your participants with the best testing experience and not impact loading times of the prototype. You can import a link to your Figma prototype into your study,  and it will carry across all the interactions you have set up. You’ll need to make sure your Figma presentation mode is made public in order to share the file with participants. If you make any updates to your Figma file, you can sync the changes in just one click. 

Help Article: Find out more about how to set up your Figma file for testing

How to create tasks 🧰

When you set up your study, you’ll create tasks for participants to complete. 

There are two different ways to build tasks in your prototype tests. You can set a correct destination by adding a start screen and a correct destination screen. That way, you can watch how participants navigate your design to find their way to the correct destination. Another option is to set a correct pathway and evaluate how participants navigate a product, app, or website based on the pathway sequence you set. You can add as many pathways or destinations as you like. 

Adding post-task questions is a great way to help gather qualitative feedback on the user's experience, capturing their thoughts, feelings, and perceptions.

Help Article: Find out how to analyze your results

Prototype testing analysis and metrics 📊

Prototype testing offers a variety of analysis options and metrics to evaluate the effectiveness and usability of your design.  By using these analysis options and metrics, you can get comprehensive insights into your prototype's performance, identify areas for improvement, and make informed design decisions:

Task results 

The task results provide a deep analysis at a task level, including the success score, directness score, time taken, misclicks, and the breakdown of the task's success and failure. They provide great insight into the usability of your design to achieve a task. 

  • Success score tells you the total percentage of participants who reached the correct destination or pathway that you defined for this task. It’s a good indicator of a prototype's usability. 
  • Directness score is the total completed results minus the ‘indirect’ results.
  • A path is ‘indirect’ when a participant backtracks, viewing the same page multiple times, or if they nominate the correct destination but don’t follow the correct pathway
  • Time taken is how long it took a participant to complete your task and can be a good indicator of how easy or difficult it was to complete. 
  • Misclicks measure the total number of clicks made on areas of your prototype that weren’t clickable, clicks that didn’t result in a page change.

Clickmaps

Clickmaps provide an aggregate view of user interactions with prototypes, visualizing click patterns to reveal how users navigate and locate information. They display hits and misses on designated clickable areas, average task completion times, and heatmaps showing where users believed the next steps to be. Filters for first, second, and third page visits allow analysis of user behavior over time, including how they adapt when backtracking. This comprehensive data helps designers understand user navigation patterns and improve prototype usability.

Participant paths 

The Paths tab in Optimal provides a powerful visualization to understand and identify common navigation patterns and potential obstacles participants encounter while completing tasks. You can include thumbnails of your screens to enhance your analysis, making it easier to pinpoint where users may face difficulties or where common paths occured.

Coming soon to prototyping 🔮

Later this year, we’re running a closed beta for video recording with prototype testing. This feature captures behaviors and insights not evident in click data alone. The browser-based recording requires no plugins, simplifying setup. Consent for recording is obtained at the start of the testing process and can be customized to align with your organization's policies. This new feature will provide deeper insights into user experience and prototype usability.

These enhancements to prototype testing offer a comprehensive toolkit for user experience analysis. By combining quantitative click data with qualitative video insights, designers and researchers can gain a more nuanced understanding of user behavior, leading to more informed decisions and improved product designs.

Interviewing Users: How to Uncover Compelling Insights

While interviewing users may seem like something that doesn’t require a guide, an understanding of different interview techniques can go a long way. This book is essentially a practical guide to the art of interviewing users. Author Steve Portigal covers how to build rapport with your participants and the art of immersing yourself in how other people see the world – both key skills for interviewers!

Usability testing

Web usability is basically the ease of use of a website. It’s a broad topic, but there are a number of useful books that explain why it’s important and outline some of the key principles.

Don't Make Me Think: A Common Sense Approach to Web Usability

Steve Krug

Don't Make Me Think: A Common Sense Approach to Web Usability

Don’t Make Me Think is the first introduction to the world of UX and usability for many people, and for good reason – it’s a concise introduction to the topics and is easy to digest. Steve Krug explains some of the key principles of intuitive navigation and information architecture clearly and without overly technical language. In the latest edition, he’s updated the book to include mobile usability considerations.

As a testament to just how popular this book is, it was released in 2000 and has since had 2 editions and sold 400,000 copies.

Design

The design–research relationship is an important one, even if it’s often misunderstood. Thankfully, authors like Don Norman and Vijay Kumar are here to explain everything.

The Design of Everyday Things

Don Norman

The Design of Everyday Things

This book, by cognitive scientist and usability engineer Don Norman, explains how design is the communication between an object and its user, and how to improve this communication as a way of improving the user experience. If nothing else, this book will force you to take another look at the design of everyday objects and assess whether or not they’re truly user-friendly.

101 Design Methods: A Structured Approach for Driving Innovation in Your Organization
