Websites or Apps testing are focus on web applications. Complete testing of a web-based system before going live can help address issues before the system is published. Issues such as the security of the web application, the basic functionality of the site, its accessibility to handicapped users and fully able users, as well as readiness for expected traffic and number of users and the ability to survive a massive spike in user traffic, both of which are related to load testing.
Done well, usability testing enables organizations to validate ideas and designs for websites and applications with real-world users, helping increase engagement, satisfaction and conversions. But executing a successful user testing strategy brings with it numerous challenges and potential hazards. Think about your redesign and conversion optimization projects. Are you at risk of committing any common testing mistakes?
Introduction to the value of usability testing
Research from the IEEE has found that fixing problems with software once development’s already begun is twice as expensive as resolving them before development commences.
Conducting lab-based usability testing that provides valuable insight into how users perceive and interact with your site or application before your project goes live can, therefore, deliver significant returns; in fact, it’s been found that for every dollar a company invests to increase usability it receives $10-$100 in benefits, and wins customer satisfaction and loyalty.
Ten most common mistakes in usability testing
However, successfully crafting, conducting and analysing these tests requires careful planning, and there are a number of challenges that you may stumble across. Here are some of the most common mistakes people fall victim to, along with tips to ensure you get the most out of any testing activity you undertake.
- 1. Recruiting unsuitable participants
Even if your testing set-up is perfect, if you’re not testing with the right people your results won’t be as useful as they might be. It’s therefore important to research participants in advance, and build a test base that reflects your audience (for example, if visitors to your website are largely female, splitting test subjects 50/50 according to gender may not be representative).
- 2. Not rehearsing your setup
It may sounds obvious but it’s crucial to check your equipment well in advance of your sessions to confirm that everything works as it should, from the devices participants will be using to the recording software you have in place, and even basics such as power points and internet connections.
- 3. Following too rigid a test plan
Preparing a test plan is vital to keep track of sessions and, perhaps more importantly, guarantee that all important areas have been covered during the testing.Ranking your questions in order of importance can help you manage this unplanned activity while ensuring that critical topics are addressed.7. Asking leading questions
- 4. When creating your test plan, make sure you review all questions for any possible bias, as otherwise you may find that you’re actually leading the user to certain answers or actions based on what you expect (or want) to happen. Also be mindful of body language, as this can provide you with an even greater understanding of user responses.
- 5. Using a one-way mirror
Many usability labs feature one-way mirrors that enable observers to monitor sessions without being seen by participants. However if the user knows they are being watched this can lead to unnatural behaviours and, subsequently, have a negative effect on your results.
- 6. Not meeting participants in reception
It’s important to remember that participants may be nervous about the session ahead, particularly if they’ve never been involved in laboratory testing before and are unsure about what’s required. Greeting them as soon as they arrive and making them feel at home helps create a relaxed and comfortable environment to support an open and insightful session.
- 7. Interrupting the participant
While test facilitators should support the participant and, as covered above, explore potentially valuable new areas of enquiry, the main purpose of usability testing is to gather feedback from representative end-users. As such, make sure you give them enough time to express their thoughts, and avoid interrupting until you’re sure they are finished.
- 8. Not considering external influences
Ideally laboratory usability testing should be performed in facilities purpose-built for the task, as this provides a controlled environment that’s tailored for best results. No matter where your sessions are conducted, though, external factors such as noise, interruptions and building work may impact your activity, but preparing well in advance can help you manage these issues.
So, that’s an introduction to some of the issues you should aim to avoid when embarking on a usability testing project, in order to unlock the full value from every one of your sessions and so improve the quality of your finished products and services.
