There’s no doubt usability is a key element of all great user experiences, how do we apply and test usability principles for a website? This article looks at usability principles in web design, how to test it, practical tips for success and a look at our remote testing tool, Treejack.

‍

A definition of usability for websites 🧐📖

‍

Web usability is defined as the extent to which a website can be used to achieve a specific task or goal by a user. It refers to the quality of the user experience and can be broken down into five key usability principles:

‍

• Ease of use: How easy is the website to use? How easily are users able to complete their goals and tasks? How much effort is required from the user?
• Learnability: How easily are users able to complete their goals and tasks the first time they use the website?
• Efficiency: How quickly can users perform tasks while using your website?
• User satisfaction: How satisfied are users with the experience the website provides? Is the experience a pleasant one?
• Impact of errors: Are users making errors when using the website and if so, how serious are the consequences of those errors? Is the design forgiving enough make it easy for errors to be corrected?

‍

Why is web usability important? 👀

‍

Aside from the obvious desire to improve the experience for the people who use our websites, web usability is crucial to your website’s survival. If your website is difficult to use, people will simply go somewhere else. In the cases where users do not have the option to go somewhere else, for example government services, poor web usability can lead to serious issues. How do we know if our website is well-designed? We test it with users.

‍

Testing usability: What are the common methods? 🖊️📖✏️📚

‍

There are many ways to evaluate web usability and here are the common methods:

‍

• Moderated usability testing: Moderated usability testing refers to testing that is conducted in-person with a participant. You might do this in a specialised usability testing lab or perhaps in the user’s contextual environment such as their home or place of business. This method allows you to test just about anything from a low fidelity paper prototype all the way up to an interactive high fidelity prototype that closely resembles the end product.
• Moderated remote usability testing: Moderated remote usability testing is very similar to the previous method but with one key difference- the facilitator and the participant/s are not in the same location. The session is still a moderated two-way conversation just over skype or via a webinar platform instead of in person. This method is particularly useful if you are short on time or unable to travel to where your users are located, e.g. overseas.
• Unmoderated remote usability testing: As the name suggests, unmoderated remote usability testing is conducted without a facilitator present. This is usually done online and provides the flexibility for your participants to complete the activity at a time that suits them. There are several remote testing tools available ( including our suite of tools ) and once a study is launched these tools take care of themselves collating the results for you and surfacing key findings using powerful visual aids.
• Guerilla testing: Guerilla testing is a powerful, quick and low cost way of obtaining user feedback on the usability of your website. Usually conducted in public spaces with large amounts of foot traffic, guerilla testing gets its name from its ‘in the wild’ nature. It is a scaled back usability testing method that usually only involves a few minutes for each test but allows you to reach large amounts of people and has very few costs associated with it.
• Heuristic evaluation: A heuristic evaluation is conducted by usability experts to assess a website against recognized usability standards and rules of thumb (heuristics). This method evaluates usability without involving the user and works best when done in conjunction with other usability testing methods eg Moderated usability testing to ensure the voice of the user is heard during the design process.
• Tree testing: Also known as a reverse card sort, tree testing is used to evaluate the findability of information on a website. This method allows you to work backwards through your information architecture and test that thinking against real world scenarios with users.
• First click testing: Research has found that 87% of users who start out on the right path from the very first click will be able to successfully complete their task while less than half ( 46%) who start down the wrong path will succeed. First click testing is used to evaluate how well a website is supporting users and also provides insights into design elements that are being noticed and those that are being ignored.
• Hallway testing: Hallway testing is a usability testing method used to gain insights from anyone nearby who is unfamiliar with your project. These might be your friends, family or the people who work in another department down the hall from you. Similar to guerilla testing but less ‘wild’. This method works best at picking up issues early in the design process before moving on to testing a more refined product with your intended audience.

Online usability testing tool: Tree testing 🌲🌳🌿

‍

Tree testing is a remote usability testing tool that uses tree testing to help you discover exactly where your users are getting lost in the structure of your website. Treejack uses a simplified text-based version of your website structure removing distractions such as navigation and visual design allowing you to test the design from its most basic level.

‍

Like any other tree test, it uses task based scenarios and includes the opportunity to ask participants pre and post study questions that can be used to gain further insights. Tree testing is a useful tool for testing those five key usability principles mentioned earlier with powerful inbuilt features that do most of the heavy lifting for you. Tree testing records and presents the following for each task:

‍

• complete details of the pathways followed by each participant
• the time taken to complete each task
• first click data
• the directness of each result
• visibility on when and where participants skipped a task

‍

Participant paths data in our tree testing tool 🛣️

‍

The level of detail recorded on the pathways followed by your participants makes it easy for you to determine the ease of use, learnability, efficiency and impact of errors of your website. The time taken to complete each task and the directness of each result also provide insights in relation to those four principles and user satisfaction can be measured through the results to your pre and post survey questions.

‍

The first click data brings in the added benefits of first click testing and knowing when and where your participants gave up and moved on can help you identify any issues.Another thing tree testing does well is the way it brings all data for each task together into one comprehensive overview that tells you everything you need to know at a glance. Tree testing's task overview- all the key information in one placeIn addition to this, tree testing also generates comprehensive pathway maps called pietrees.

‍

Each junction in the pathway is a piechart showing a statistical breakdown of participant activity at that point in the site structure including details about: how many were on the right track, how many were following the incorrect path and how many turned around and went back. These beautiful diagrams tell the story of your usability testing and are useful for communicating the results to your stakeholders.

‍

Usability testing tips 🪄

‍

Here are seven practical usability testing tips to get you started:

‍

• Test early and often: Usability testing isn’t something that only happens at the end of the project. Start your testing as soon as possible and iterate your design based on findings. There are so many different ways to test an idea with users and you have the flexibility to scale it back to suit your needs.
• Try testing with paper prototypes: Just like there are many usability testing methods, there are also several ways to present your designs to your participant during testing. Fully functioning high fidelity prototypes are amazing but they’re not always feasible (especially if you followed the previous tip of test early and often). Paper prototypes work well for usability testing because your participant can draw on them and their own ideas- they’re also more likely to feel comfortable providing feedback on work that is less resolved! You could also use paper prototypes to form the basis for collaborative design sessions with your users by showing them your idea and asking them to redesign or design the next page/screen.
• Run a benchmarking round of testing: Test the current state of the design to understand how your users feel about it. This is especially useful if you are planning to redesign an existing product or service and will save you time in the problem identification stages.
• Bring stakeholders and clients into the testing process: Hearing how a product or service is performing direct from a user can be quite a powerful experience for a stakeholder or client. If you are running your usability testing in a lab with an observation room, invite them to attend as observers and also include them in your post session debriefs. They’ll gain feedback straight from the source and you’ll gain an extra pair of eyes and ears in the observation room. If you’re not using a lab or doing a different type of testing, try to find ways to include them as observers in some way. Also, don’t forget to remind them that as observers they will need to stay silent for the entire session beyond introducing themselves so as not to influence the participant - unless you’ve allocated time for questions.
• Make the most of available resources: Given all the usability testing options out there, there’s really no excuse for not testing a design with users. Whether it’s time, money, human resources or all of the above making it difficult for you, there’s always something you can do. Think creatively about ways to engage users in the process and consider combining elements of different methods or scaling down to something like hallway testing or guerilla testing. It is far better to have a less than perfect testing method than to not test at all.
• Never analyse your findings alone: Always analyse your usability testing results as a team or with at least one other person. Making sense of the results can be quite a big task and it is easy to miss or forget key insights. Bring the team together and affinity diagram your observations and notes after each usability testing session to ensure everything is captured. You could also use Reframer to record your observations live during each session because it does most of the analysis work for you by surfacing common themes and patterns as they emerge. Your whole team can use it too saving you time.
• Engage your stakeholders by presenting your findings in creative ways: No one reads thirty page reports anymore. Help your stakeholders and clients feel engaged and included in the process by delivering the usability testing results in an easily digestible format that has a lasting impact. You might create an A4 size one page summary, or maybe an A0 size wall poster to tell everyone in the office the story of your usability testing or you could create a short video with snippets taken from your usability testing sessions (with participant permission of course) to communicate your findings. Remember you’re also providing an experience for your clients and stakeholders so make sure your results are as usable as what you just tested.

“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)

‍

‍

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.
