According to an article called 5 Types of Usability Tests by Jeff Sauro, there are different types of usability tests that address different goals of research. Performance testing is used to evaluate the effectivity of task completion once the wireframes have been created using the insights acquired from formative testing. Daniel Schwarz advocates for better UX design alongside industry leaders such as Adobe, Wix, InVision, Supernova, Net Magazine, Web Designer Magazine, and more. Deciding on which kind of test you are going to use depends on what do you have of your product and what are you trying to find out about it. Let’s take a look at the different types of usability testing. Interface types are mobile (website or apps), desktop (software or website), or a physical device (like a thermostat). Denver, Colorado 80206 There are many different types of usability testing, but the core elements in most usability tests are the facilitator, the tasks, and the participant. Usability testing is one of the best processes in which you can watch and track down an actual user. Are Sliders More Sensitive than Numeric Rating Scales? Interestingly, usability testing can also be conducted without users, using what’s known as eye-tracking software. However, we can’t rely on these usability heuristics alone. We also need what’s called formative usability testing, where we base theories on user insights; and summative testing, where we confirm those theories. We'll help you determine which type of study is best for your circumstances, plan the study details, carry out the research, and prepare rich analysis of the findings to ensure you have actionable, prioritized results. Interface types are mobile (website or apps), desktop (software or website), or a physical device (like a thermostat). Below: the user has created three navigation categories and sorted the navigation items into those categories, even using color to further sub-categorize them neatly. Let’s assume you own a boat rides company in Amsterdam and you decide to build a simple landing page where people can go to book a boat ride. But did those design changes actually make the interface easier to use? A good idea would be to draw your ideal perceptual map(s) before usability testing has even started. When you need to understand both where participants eyes are drawn in designs and the sequences of gaze paths, an eye-tracking study is the way to go. The approach here is to ask the usability tester what they think something means or does without interacting with it. There are a lot of Internet platforms which allow their visitors to find what they want, however, not all of them can boast of a high level of sites usability. You can conduct comparative moderated remote or in-person studies; just plan on dedicating a lot of time for moderation and consider a within-subjects approach (where the same participants attempt the same tasks on all competitors). One We, as testers are aware of the various types of Software Testing such as Functional Testing, Non-Functional Testing, Automation Testing, Agile Testing, and their sub-types, etc. We can differentiate two types of remote usability testing: Moderated- enables direct interaction with users online or observing users while they complete tasks for a test. During a visual affordance test, users are first asked to circle the elements they believe to be clickable, and then again, with elements they don’t believe to be clickable. We conduct every type of usability test at MeasuringU and would love to help you conduct the right ones for your goals. TYPES OF USABILITY TESTS. The current technology only supports in-person testing. Problem discovery studies are usually conducted using a moderated approach, where a facilitator can really dig into the actions and utterances of the participant to uncover problems. Consequently they are usually conducted using the unmoderated remote mode if it is a website benchmark. User testing requires having real people use your app to see how well it functions from a nonbiased and unfamiliar perspective. Think of usability testing as a compass to tell you where your product fits within a perceptual map, where instead of quality and price, we’re measuring (in this case) learnability and feature variety. This is the most common type of usability study. This is also known as formative studies, the goal is to find out as many problems as possible and fix them. Participants attempt a realistic set of tasks scenarios. Don’t confuse the five usability testing types with the interface type or the testing modes. Each of us would have come across several types of testing in our testing journey. The test monitor observes to determine if an interface has clear, intuitive design or if there is much user confusion. These studies are often referred to as formative studies, a term that comes from educational research. Measuring the usability of an interface before design changes are made allows you to set a benchmark to compare future designs against. The term formative comes from educational research where it’s used to describe testing as a method for diagnosing problem areas in a student’s learning. Learn if participants are able to complete specified tasks successfully and 2. Moderated remotely: Someone monitors the usability test as it happens. The Many Types of User Testing Methods There are many types of user tests, from behavioral and attitudinal to qualitative and quantitative, each with a set number of participants for optimal results. Wait…if tree testing indicates an issue, how do we identify the solution? Where people look and where they click are similar, but not always the same. There are three main testing methods; each has its strengths and weaknesses : With the type of interface and different testing methods in mind here are the five types of usability tests, each addressing a different research goal. One of the best ways to put your task scenarios and metrics into context is to see how you stack up against the competition (or previous designs). Usability testing reduces the risk of building the wrong thing and focuses on measuring a human-made product's capacity to meet its intended purpose. The difference between usability testing and user testing is confusing to most developers, project managers, and even UX designers. Testing modes or methods are the ways to conduct a usability study on any interface type. With the types of interface and different testing methods in mind here are four types of usability tests (PELB), each addressing a different research goal. Here are a few of the most common and useful: Exploratory test: Conducted early on in the design process, before a website has been published. With these insights we can fine-tune the clickability and tapability of interactive elements. Types of Usability Testing. To get a genuine result the test will usually take place in a lab and often unveils more than if you were having a participant undertake a task on their own. With these insights in mind, we can then design the task or user flows and visual hierarchy in a way that adds extra emphasis on the chosen functions, and then depict this as what’s called a task or user flow map, a sort-of upgrade to a sitemap that specifically highlights the various user flows. Often enough, this is done with a simple survey. Problem Discovery . Instruct the tester to choose three functions from the tree map (also known as a sitemap) — for example, subscribe, pricing, and checkout could be three functions the user deems important. Below: a mockup (left), a video feed of the user testing it, a chat window, and finally, somewhere to take notes — here, somebody is running a usability test using Lookback. Remote user testing tools such as Lookback and UserTesting, which integrate with everyday screen design tools such as Marvel and InVision, are very suited for this. Identify how long it takes to complete specified tasks 3. It is closer to lab testing. This type of historical data really provides context to assess the impact of design changes. That being said, eye-tracking can reveal enough insights to raise important questions, questions that we can then ask during some of the usability tests above. Problem discovery studies are often called formative studies. There are many different types of usability tests. By having participants attempt the same tasks repeatedly in a study, you can quantify the learning curve. Rating Scale Best Practices: 8 Topics Examined. Don’t confuse the five usability testing types with the interface type or the testing modes. people don’t often realise they are making a category error: they are discussing different kinds of thing. A stand-alone benchmark generates a lot of data, but without a comparison to an earlier benchmark you’re often left wondering “are these results good or bad?” To provide a meaningful comparison, have another set of participants attempt the same set of tasks on competing websites or products. One of the most important concepts in all of UX research is the idea of using problem discovery studies iteratively throughout product development. Problems were found and new designs were created. It can be performed by the internal team or a small set of end-users who explore the different functionalities of the application and share the usability defects. This was a common complaint from enterprise software developers who knew users would be both trained and using a system daily for years. While training should not be a crutch for bad interface design, you can simulate both the effects of training and repeated use in a usability study. Although you’ll want to test for usability often and repeatedly, when you’re sure that your wireframes are offering the best user experience, it’s time to mockup the final design using a UI design tool. Functional salience tests are used to decipher which functions are most important, which then helps us decide how best to design the content and UI. Basically, guerrilla testing means going into a public place such as a coffee shop to ask people about your prototype. Provide your email below and we’ll keep you updated about new content and secret discounts, Learn how we treat your data in our Privacy Policy. There are different kinds of usability tests addressing different goals. From Soared to Plummeted: Can We Quantify Change Verbs? Guerilla testing is the simplest form of usability testing. The same idea applies to an interface: From the evaluation, what problems can be found and corrected to make the interface easier to use? Types of Usability Testing Research . We can then follow up with tree testing again to make sure that users are finding the right things quickly. There are many different types of digital usability tests, like heat map tracking tools for instance, or you can do remote testing, or you can plop someone in front of a computer and track their eye movements. Usability testing is the practice of testing how easy a design is to use with a group of representative users. An expectancy test is an interesting one, as the tester can answer with some rather hilarious responses if the usability is bad enough. However, if participants are still encountering problems after repeated trials of the same task (especially after some training), you have some compelling evidence for fixing problems that don’t only affect first time users. 3300 E 1st Ave. Suite 370 We’d love to hear it! However, one should not mix it with the interface type or testing modes. Usability testing tools like Usertesting.com allow you to watch someone across the world using your website to accomplish tasks that your write. The earlier issues are identified and fixed, the less expensive the fixes will be in terms of both staff time and possible impact to the schedule. You can still conduct a formative study using the unmoderated remote method if you have participants think aloud and have their screens and webcams recorded. 1 + 303-578-2801 - MST Also, new kid UserLook helps designers kickstart usability testing in seconds — a huge advantage to UserLook is that it’s free if you source testers from your own userbase. Perception tests can be both formative and summative depending on whether we’re showing users a mockup, or simply a moodboard with various abstract visual elements. A facilitator will be located with the participant or in a group, and will be on hand to answer questions and respond to any feedback. Again, Whimsical is a top tool for this. 5-second usability tests are simple but effective, and like many of the usability tests outlined in this lesson, they can also be carried out using user/usability testing tools. Nowadays’ computerized life makes the users go to the different websites in order to get the necessary information. When you’re ready, read our UI design tool comparison. Building Nomad Noms currently. There are usually complaints about the realistic nature of the task scenarios or that some tasks may be “unfair.” Every usability study comes with some level of artificiality that can threaten the validity of the findings. This method of testing is one of the top ways by which you can understand the how your website can be experienced by a real user. A question could be: “Where would you go to find a meal plan?” — which could yield different results depending on whether the nav category is labeled as Meal Plans, or else something more obscure like Downloads. However, if there is more than one distinct user type, you may want to increase this number to accommodate the different user types. Remote vs. in-person usability testing Remote usability tests are done over the internet or by phone; in-person testing, as the name suggests, requires the test to be completed in the physical presence of a UX researcher/moderator. Got feedback? There are two types of remote usability testing: synchronous or asynchronous. Privacy Policy OK The goal of this test is to uncover as many usability issues as possible by asking participants to complete a series of tasks. You can conduct eye-tracking on just about any device, although we mostly limit it to desktop and tablet websites and apps. Problem Discovery. It is different from beta testing, in which you provide users with access to your site when it is completed. The synchronic approach allows designers to … eye-tracking with problem discovery). Usability testing is very important if you want to pursue a career in UX practice. Eye-tracking tools offer a number of useful features; heatmaps (which track where users move their mice), scrollmaps (which track where users scroll to and how long they stop to look around), and clickmaps (which track where users actually tap/click). Testing modes or methods are the ways to conduct a usability study on any interface type. Also, you might find that affinity mapping is useful for clustering recurring feedback, which helps us determine which issues are high-priority, and we can do this with all kinds of testing and research. From this we can identify any flaws not already identified. Would they rather skip the sign up, or the onboarding? It is more concerned with the design intuitiveness of the product and tested with users who have no prior exposure to it. Website usability testing is a technique of observing the ease of use of a website design while it is still a work in progress. The goal is to uncover (and fix) as many usability problems as possible. While this blurs the lines between UX and marketing, branding does influence our decision to interact with a business, especially when trust, security, and legalities are concerned. Earlier on in the series we explored the basic concepts of usability, which offers a decent base for us to begin forming theories. Consequently, the findings often describe initial use, rather than usage over time. This guide forms part of our ebook, A Beginner’s Guide to Designing UX. A/B testing is a form of usability testing that’s used when there are two different options from among which the company is deciding. Some people believe user testing is the process of validating the demand for a product, whereas usability testing determines if end-users can or cannot do what they need to do on an existing prototype. A summative evaluation is the more familiar (and often maligned) method of testing students to assess how much a learner knows (usually via a standardized test). In addition to the usual recruitment and facilitator time, you should plan 10 minutes of analysis time for every 1 minute of eye-tracking data collected with participants. Quantifying changes is also one of the essential pillars of UX research. Nielsen Norman Group researchers are experts in many different types of usability research. Fullstory, Hotjar, and Crazy Egg are three terrific tools for eye-tracking. If the user base is one homogenous type of user, you can pick up most of the usability issues with 5 to 6 users. In such studies you’re often more interested in performance data like task-time than initial impressions and problem discovery. Businesses that spend only 10% of their budget on usability improvements see, on average, a 135% increase in their desired metrics, so the ROI of usability is significant. Eye-tracking studies are also time-intensive. The second reason is that it takes a lot of guesswork out of the elimination and bug testing process. Learnability studies are split between a moderated in-person approach where you can control the testing environment and extraneous variables more easily, or unmoderated remote, where you can collect a larger sample size to obtain more precise estimates of your metrics. Previously: blog editor at Toptal and SitePoint. Does the user care deeply about searching for things? Because you’re comparing, you’ll need a larger sample size to detect differences; for that reason, many comparative studies are done using an unmoderated remote approach. There are three different ways that usability tests can happen: In-person: A person is there moderating the test. You can either recruit family and friends to try using the app or find focus groups that are willing to explore different features and functionalities. This website uses cookies to ensure you get the best experience on our website. This test is used to identify the feelings aroused from a set of mockups, where users are asked to circle adjectives that best describe the brand, and from this we can then decipher if users are associating the brand with the desired attributes. So, why bother with different types of usability testing? While that concludes site structure and navigation, it certainly doesn’t conclude the overall information architecture. While eye-tracking software doesn’t reveal solutions, it can set us in the right direction. During a usability test, you will: 1. Each type addresses different research goals. Brand testing helps us evaluate our brand message. Interface types include mobile, desktop, and a physical device. Wham bam, there’s your navigation. Test participants are chosen randomly. While tools like Optimal Sort are designed for card sorting, card sorting can also be conducted in the real world by having testers simply arrange cards, sticky notes, or something of the sort (pun not intended) into the structure they deem appropriate. Rapid User Testing Rapid User Testing. Conducting usability tests. During open card sorting, testers are asked to sort navigation items into appropriate categories; categories of which are created by the tester. Interestingly, tree testing can be both formative and summative. Usability testing is a type of non-functional testing that determines the degree to which an application can be easily used and operated. Note: tree testing is also known as reverse card sorting. Even when using participants who have experience with an interface, the task details are almost always unfamiliar in some way. But let’s set one thing straight, eye-tracking by itself is not effective, because without talking to users we’re missing context, intent, and emotion. Before finally building our first mid-fidelity wireframes, we need to know which functions are the most important. How to Create Task Scenarios. Benchmark studies are often called summative studies, which also comes from educational research. First things first, to run an effective usability test you don’t need formal ‘laboratory conditions.’ It’s far better to run some usability testing using what you have to hand than to run no usability testing at all.You might be wondering, why bother? The first reason is that we are not all great and experienced analysts, and an analyst’s career will teach him/her that experience is as valuable and necessary as it is damaging and blinding. Alternatively, wireframe tools such as Whimsical also have card/sticky functionality. That’s right, sometimes the best way is to ask users directly, which offers rich insight into the user’s mental model. A problem discovery usability test is the most common type of usability study. The reason is twofold. But there are different types of user testing that suit different types of goals. . It usually involves observing users as they attempt to complete tasks and can be done for different types … If something doesn’t seem to be working, an expectancy test can reveal why — this can happen when trying to innovate new ideas or introduce unfamiliar design concepts. Most users are only willing to allocate 5 seconds to an app or website, so if the user for any reason becomes stalled, they will hit the back button. They are asked to perform a quick usability test, … Usability testing is a technique used to help discover problems or bottle-necks in your design. 1. Testing modes include Moderated in-person, Moderated remote, and Unmoderated remote. Despite the differences in usability testing modes and flavors, all generally have the following in common: The “right” method depends on your research goals and many studies involve a combination of the usability types (e.g. Collecting benchmark data tells you how usable your website is and how users are performing on key tasks. There are many different ways of testing usability, and this is because every test has a main objective and a context where it is better to be applied on. For example, UserTestingprovides videos of real u… Discreetly, we then assign the tester a score — 2 for Completed, 1 for Had Difficulty, and 0 for Fail — and after all the tests are complete, we can use the scores and notes to measure success rate, task time, and overall user satisfaction. The goal of a benchmark study is to answer the question: How usable is the interface? Usability testing lets the design and development teams identify problems before they are coded. Synchronous remote testing is handled via video conferencing as well as various sharing tools such as WebEx or GoToMeeting. We now have some fantastic insights — literally a map — telling us how our design should be wireframed. Users are given a set of tasks to carry out. Usability testing is a technique used in user-centered interaction design to evaluate a product by testing it on users. Latin and Greco-Latin Experimental Designs for UX Research, Improving the Prediction of the Number of Usability Problems, Quantifying The User Experience: Practical Statistics For User Research, Excel & R Companion to the 2nd Edition of Quantifying the User Experience. Benchmark studies require a larger sample size in order to get tighter confidence intervals. This type of testing is usually done at an early stage when an application itself is not yet complete. It is one of the most common types of a usability test. Each type addresses different research goals. Data is collected about what users do and say (behavioral and attitudinal data). While we often talk about usability tests as if there is one type of usability test, the truth is there are several varieties of usability tests. Following on from the last lesson where we briefly talked about using wireframes to visualize low-fidelity ideas, in this lesson we’ll learn about usability testing, the method of forming, refuting, or validating the theories that we hold about our design’s usability, which in turns helps us transition our design from low-fidelity to mid- and high-fidelity. A usability-testing session involves a participant and a facilitator who gives tasks to the participant and observes the participant’s behavior. 5-second usability tests are used to determine whether or not users can recall something from memory, such as the name of the brand, or what the app, website, or specific screen does. Most usability studies assess first time use. Formative testing tells us what needs to be improved, whereas summative testing indicates whether or not these improvements were successful. Contact Us, User Experience Salaries & Calculator (2018). Usability Testing Definition. Suitable tree testing tools include User Zoom and Treejack by Optimal Workshop. Tip: pay attention to how users overcome roadblocks, as this will reveal solutions. Below: notice how the information architecture is evolving? When you have a handful of participants attempt a few realistic tasks you can uncover the most common issues. Knowing what the different user types are, and the number of user types, will help you gauge how many participants you will need for the user test. Formatively, tree testing can reveal what’s wrong with our navigation labeling or structuring, however, summatively it can confirm that a navigation redesign now offers optimal usability. Send us a tweet @ uxtricksdesign. 5-second usability tests are used to determine whether or not users can recall something from memory, such as the name of the brand, or what the app, website, or specific screen does. Below: screens copied from Whimsical to Freehand, where users can draw on them. Un-moderated- participants independently complete testing without interaction with the test moderator. Attitudinal and behavioral testing is summed up as “what people say” vs. “what people do.” Many times the two are very different. This can be seen as an irreplaceable usability practice, since it gives direct input on how real users use the system. Formative testing reveals insights that we can use to mock up our mid- and high-fidelity wireframes, whereas summative testing is often used to validate these wireframes once created. Given a variety of example scenarios, users are asked to complete tasks as we watch, listen, and ask questions to help the user communicate their feedback as we take notes. While it should be manageable to find people who are willing to test your application and give feedback, there are also companies who are dedicated to setting up user testing services for you. A closed card sort test is a summative variation of open card sorting, where the categories are already named, and it’s simply a case of the tester confirming where each navigation item belongs. We work with many companies that perform benchmark studies annually. A free exploration test is a summative test where the user has 5 minutes to explore freely while speaking aloud. But there are inexpensive, pen-to-paper types of usability tests also. During tree testing, users are shown a tree-like sitemap of an app or website’s navigation without the distraction of visual elements, and are asked where they would navigate to in order to find something.
