User Testing
Part 2: Getting Started

 

So what is it, exactly, you're testing for? How many subjects should you recruit for testing, and what kind of platform will you be testing them on? Answer these questions correctly, and you can save yourself a lot of work down the road.
Transcript Now that we've established clear objectives, it's time to get down to what you'll be testing. Your test plan will depend on what you're developing. You might be working with a wireframe for a new website. Or maybe you're developing an app for iOS. Or maybe you're just creating a few additional pages for an existing website. Next, you're going to want to choose the hardware platform for testing. Is it going to be an iPhone or a Chromebook, a desktop with a 27-inch monitor or an iPad mini? For websites, we're going to want to test and use a variety of platforms and browsers. For apps, there should be fewer variations to test. Obviously, you want to concentrate on testing devices that are most popular with your users. Next, you want to select your test subjects. Ideally, you're looking for people who are both likely to use your app or website and are incredibly articulate. In the real world, you might just get one or the other. Sometimes the only criteria you need for selecting your testers is demographics. Say age, gender, income. But you can always get closer to your target audience by asking them some screening questions. For example, do you do most of the grocery shopping in your household? Or how often do you go out to the movies? If your team is using personas, try to select users that match as closely as possible to those personas. Once you have a good pool to select from, you want to decide how many testers to recruit. Studies have shown that five participants are usually enough to uncover 85% of the usability problems on a website. So if you recruit more than five testers, you're likely facing diminishing returns. But again, it depends on what you're testing. If you're testing for something as open-ended as user satisfaction, a large test group could be useful in drawing out a range of responses. Before running a full round of tests, it's never a bad idea to do a "dry run". Using a single tester running one subject through your test will help you to spot any errors in your plan. So, in summary, decide what type of product you're testing. Choose the appropriate platform, then recruit a pool of testers. Then decide on the appropriate number of testers to draw from that pool. This number will be determined largely by the type of test you're conducting. And, finally, test it with a dry run. If you take these steps in order, you could save yourself and your team a lot of unnecessary work. Next up, building a plan.
