Why information architecture is the foundation of UX

The term ‘usability’ captures sentiments of how usable, useful, enjoyable, and intuitive a website or app is perceived by users. By its very nature, usability is somewhat subjective. But what we’re really looking for when we talk about usability is how well a website can be used to achieve a specific task or goal. Using this definition we can analyze usability metrics (standard units of measurement) to understand how well user experience design is performing.

‍

Usability metrics provide helpful insights before and after any digital product is launched. They help us form a deeper understanding of how we can design with the user front of mind. This user-centered design approach is considered the best-practice in building effective information architecture and user experiences that help websites, apps, and software meet and exceed users' needs.

‍

In this article, we’ll highlight key usability metrics, how to measure and understand them, and how you can apply them to improve user experience.

‍

Understanding Usability Metrics

‍

Usability metrics aim to understand three core elements of usability, namely: effectiveness, efficiency, and satisfaction. A variety of research techniques offer designers an avenue for quantifying usability. Quantifying usability is key because we want to measure and understand it objectively, rather than making assumptions.

‍

Types of Usability Metrics
‍

There are a few key metrics that we can measure directly if we’re looking to quantify effectiveness, efficiency, and satisfaction. Here are four common examples:

‍

• Success rate: Also known as ‘completion rate’, success rate is the percentage of users who were able to successfully complete the tasks.
• Time-based efficiency: Also known as ‘time on task’, time-based efficiency measures how much time a user needs to complete a certain task.
• Number of errors: Sounds like what it is! It measures the average number of times where an error occurred per user when performing a given task.
• Post-task satisfaction: Measures a user's general impression or satisfaction after completing (or not completing) a given task.

‍

How to Collect Usability Metrics

‍
Usability metrics are outputs from research techniques deployed when conducting usability testing. Usability testing in web design, for example, involves assessing how a user interacts with the website by observing (and listening to) users completing defined tasks, such as purchasing a product or signing up for newsletters.

‍

Conducting usability testing and collecting usability metrics usually involves:

‍

• Defining a set of tasks that you want to test
• Recruitment of test participants
• Observing participants (remotely or in-person)
• Recording detailed observations
• Follow-up satisfaction survey or questionnaire

‍

Tools such Reframer are helpful in conducting usability tests remotely, and they enable live collaboration of multiple team members. It is extremely handy when trying to record and organize those insightful observations! Using paper prototypes is an inexpensive way to test usability early in the design process.

‍

The Importance of Usability Metrics in User-Centered Design

‍

User-centered design challenges designers to put user needs first. This means in order to deploy user-centered design, you need to understand your user. This is where usability testing and metrics add value to website and app performance; they provide direct, objective insight into user behavior, needs, and frustrations. If your user isn’t getting what they want or expect, they’ll simply leave and look elsewhere.

‍

Usability metrics identify which parts of your design aren’t hitting the mark. Recognizing where users might be having trouble completing certain actions, or where users are regularly making errors, are vital insights when implementing user-centered design. In short, user-centered design relies on data-driven user insight.

‍

But why hark on about usability metrics and user-centered design? Because at the heart of most successful businesses is a well-solved user problem. Take Spotify, for example, which solved the problem of dodgy, pirated digital files being so unreliable. People liked access to free digital music, but they had to battle viruses and fake files to get it. With Spotify, for a small monthly fee, or the cost of listening to a few ads, users have the best of both worlds. The same principle applies to user experience - identify recurring problems, then solve them.

‍

Best Practices for Using Usability Metrics

‍

Usability metrics should be analyzed by design teams of every size. However, there are some things to bear in mind when using usability metrics to inform design decisions:

‍

• Defining success: Usability metrics are only valuable if they are being measured against clearly defined benchmarks. Many tasks and processes are unique to each business, so use appropriate comparisons and targets; usually in the form of an ‘optimized’ user (a user with high efficiency).
• Real user metrics: Be sure to test with participants that represent your final user base. For example, there’s little point in testing your team, who will likely be intimately aware of your business structure, terminology, and internal workflows.
• Test early: Usability testing and subsequent usability metrics provide the most impact early on in the design process. This usually means testing an early prototype or even a paper prototype. Early testing helps to avoid any significant, unforeseen challenges that could be difficult to rewind in your information architecture.
• Regular testing: Usability metrics can change over time as user behavior and familiarity with digital products evolve. You should also test and analyze the usability of new feature releases on your website or app.

‍

Remember, data analysis is only as good as the data itself. Give yourself the best chance of designing exceptional user experiences by collecting, researching, and analyzing meaningful and accurate usability metrics.

‍

Conclusion

‍

Usability metrics are a guiding light when it comes to user experience. As the old saying goes, “you can’t manage what you can’t measure”. By including usability metrics in your design process, you invite direct user feedback into your product. This is ideal because we want to leave any assumptions or guesswork about user experience at the door.

‍

User-centered design inherently relies on constant user research. Usability metrics such as success rate, time-based efficiency, number of errors, and post-task satisfaction will highlight potential shortcomings in your design. Subsequently, they identify where improvements can be made, AND they lay down a benchmark to check whether any resulting updates addressed the issues.

Sitting inside any beautifully crafted and designed digital product, there must be a fully functional and considered information architecture.

‍

As much as information architecture shouldn’t be developed in a vacuum. Neither should the design and look of digital products. In fact, a large proportion of the function of digital designers is devoted to supporting users locating content they need and driving them towards content that the product owners want them to find.

‍

Incorporating visual markers to make sure that certain content is distinct from the rest or creating layers that demonstrate the diverse content on a product.

‍

If you do not have quality content, it is impossible to design a quality digital product. It all comes back to creating a user experience that makes sense and is designed to make task completion simple. And this relates back to designing the product with the content planned for it in mind.

8 Principles of information architecture, according to Dan Brown 🏗️

‍

As a designer, the more you know about information architecture, the better the products you design will meet your user requirements and deliver what they need. If you work with an information architect, even better. If you’re still learning about information architecture the 8 Principles according to Dan Brown is a great place to begin.

‍

If you haven’t come across Dan Brown yet, you have more than likely come across his 8 principles. Dan Brown is one of the UX world's most prolific experts with a career that spans most areas of UX designs. He’s written 3 books on the subject and experience across a multitude of high profile projects. Aiding large organizations to make the most of their user experience.

‍

1. The principle of objects: Content should be treated as a living, breathing thing. It has lifecycles, behaviors, and attributes.
2. The principle of choices: Less is more. Keep the number of choices to a minimum.
3. The principle of disclosure: Show a preview of information that will help users understand what kind of information is hidden if they dig deeper.
4. The principle of examples: Show examples of content when describing the content of the categories.
5. The principle of front doors: Assume that at least 50% of users will use a different entry point than the home page.
6. The principle of multiple classifications: Offer users several different classification schemes to browse the site’s content.
7. The principle of focused navigation: Keep navigation simple and never mix different things.
8. The principle of growth: Assume that the content on the website will grow. Make sure the website is scalable.

‍

It’s highly likely that you’ve already used some, or all, of these IA principles in your designs. Don’t be shy about mastering them, or at the very least be familiar. They can only help you become a better user experience designer.

Mastering the 8 principles, according to IA expert Dan Brown will see you mastering the complex tasks of information architecture. Understanding IA is key to creating digital designs with a content structure that is functional, logical and just what your users need to navigate your product. Design without good IA doesn’t work as well, just as a content structure without a well designed interface will not engage users.

What is Information Architecture?

‍

Information architecture (IA) is a term used to describe how content or information is organised and arranged. This can relate to a website, a retail store or an app. And you could even consider the way a library is sorted to be IA. 

‍

For the purposes of this we will be focussed on websites. IA is fundamentally important to the success of your website. It determines how your users will access the information and the success of their user experience (UX) whilst on your website. And ultimately if you can keep users on your website long enough to complete their task.

‍

IA can be broken down into 3 main areas to consider when building great user experience:

‍

• Navigation: How people make their way through information (website content)
• Labels: How information is named and represented.
• Search: How people will look for information (keywords, categories)

‍

When put like this it does seem pretty straightforward. Maybe even simple? But these tasks need to be straightforward for your users. Putting thought, time and research in at the front of your design and build can mean an intuitive website is built. But at any point in your websites life cycle it can be of value to test and review. IA is the structure that sits in behind and allows the design to tell the story and the content to be found in an easy way.

‍

Why is Information Architecture important to web design? 🏗️

‍

If you’ve ever tried to use something and thought, “where am I supposed to go next?” or “this doesn’t make any sense,” you are encountering an issue with an information ‍architecture.

The Information Architecture Institute

‍

The way in which your users will use your website depends largely on how the information is presented and organised. By following through the tasks that you expect your users to undertake you can better understand the user experience. If the user can easily flow from point to point, finding what they need in a quick and efficient (and ideally intuitive manner) they are far more likely to stick around. And return when they need to.

‍

The opposite is definitely true also. If users find your website difficult to follow, hard to navigate and get lost or confused. They will not stick around to find out more. They will move on, and swiftly, to your competition. Frustrated, and disengaged. You will find it difficult to win them back.

‍

What does good information architecture look like for my users? 👀

‍

By providing a simple, clear and straightforward path users can stay focussed on their task, removing overwhelm and confusion. How often do you disappear ‘down a rabbit hole’ when on the internet? Confusing paths or overwhelming options may mean users move off on tangents, and become less likely to complete their initial task. Ultimately the best user experience is one that delivers the right information at the right time. Not too slow and not too complicated. 

‍

Always keep in mind that a great IA is:

‍

• Navigation: Always think straightforward, simple and intuitive.  Keep the navigation menu clean, clear and brief. Content and information where it’s expected to be. No point putting dog collars under dog food.
• Labels: Consider how pages, content and information is named. This needs to be direct and simple to understand. If you want people to find your store label the page ‘location’ or ‘find us’ or even ‘find our store’.
• Search: Most of your users will use search as a last resort. They will try to navigate their way through your website before resorting to a search option. Considering carefully the keywords for information that support the search tool. If they have already failed to find the information through your navigation, don’t let them down now.

‍

With all of these lined up in behind great web design, which is clear, bright and attractive. Along with language which appeals to your user.  You are providing a UX that will entice, engage and ultimately keep them on your website and converting.

‍

What does great information architecture look like for my organization?

‍

Great IA goes beyond simply being about your user experience. Your organization can benefit hugely with testing, research and insights put into your website IA. 

‍

With an IA that creates an easy navigable and engaging website your users are less likely to move off to your competitors. You’ve worked hard to get them to your website, through marketing and SEO. Delivering what your user expects and making it easy to find, means they will complete their task, and are far more likely to return. 

‍

By finding what they need quickly, and intuitively, users are more likely to be converted and generate leads or sales. Delivering and answering questions can also reduce the need for support. If you can, your organization's website should answer your users questions, before they complete. This means they are less likely to need to email and /or call for support, reducing overheads and time lag before conversion.

‍

Your organization's reputation is so important, your website may be your only interaction with users. If they have an easy user experience, their questions answered, and are able to complete what they need simply they leave with a great impression of your organization. They are more likely to return and their overall takeaway is that your organization is trustworthy, organised and easy to deal with. The opposite is quite possible with poor IA and design. You get but one chance to grab their attention and keep them. Do it badly and you may never get them back.

User research with OptimalSort

‍

Of course the best website IA is based on your users experience. And there is no better way to get a full understanding of your users than by conducting research. At any point in your website's life cycle it can be beneficial to undertake research such as card sorting. At the beginning stages of your website build is best, but your website should be evolving as your organization does, therefore any time there are shifts in what you do or offer is a great time to revisit your UX and how best to deliver this. OptimalSort tests users on how they intuitively would like to see information sorted on your website. Building IA based on data, rather than assumptions, will mean that content and information can be sorted in a way that truly delivers a simple and intuitive experience.

‍

Maintaining your website with Treejack

‍

With a great IA, based on card sorting user research, your website content needs to be maintained. Tree testing allows you to see where your users are getting lost in your website navigation. And also how they expect to look for key information. The Treejack tool provides real user insights on how your website navigation is working, how it can work better, and ultimately how to fix paths that don’t work. Providing hard data to inform an intuitive IA.
