What Are Usability Metrics?Usability metrics measure how easy and effective your product is for users. Keeping track of usability metrics allows you to gauge whether users can accomplish your product’s goals. They also highlight any issues with your product that need to be fixed.
How to Measure Usability Metrics?
Don’t be disheartened by a small number of errors in your usability testing. Mistakes happen, and they aren’t always a reflection of your product.
Remember the task duration metric from above? Efficiency is intrinsically tied to task duration.
The efficiency metric combines task duration with success rates to assess the effectiveness and overall efficiency of the task. The following formula represents overall relative efficiency:
5. Single Ease Question (SEQ)
The single ease question (SEQ) is a seven-point rating scale determining how difficult users found a task. The SEQ should be completed immediately after the task to get a more reliable response. Ideally, you’ll want an overall score of 4.5 or more.
If you receive too many low scores, you’ll need to ask why to determine whether there’s an underlying issue that needs solving.
6. System Usability Scale (SUS)
The system usability scale (SUS) is one of the best customer experience analytics solutions for gaining fast and reliable results.
The SUS consists of ten questions with five response options for each question. Responses range from strongly disagree to strongly agree. Feedback from these questions allows you to find where your product sits on the usability scale. These results can then be used to compare with competitors’ products.
7. Customer Satisfaction (CSAT)
The CSAT metric tells you how satisfied customers are with various aspects of your product. For most industries, it’s one of the most important metrics. CSAT surveys are helpful because they let you choose which questions to ask, meaning you gain reliable insights for specific questions.
Now that you know what usability metrics to track, let’s take a look at how to improve them.
Ideas for How to Improve Core Usability Metrics
There are many different ways to improve the core usability metrics, but we’ve singled out the two most exciting ideas.
Add short instructions or guidelines
Adding short instructions or guidelines is a simple and effective way to boost core usability metrics.
New users won’t have previous experience with your product. Therefore, users may initially find it hard to navigate and perform their intended tasks, which can affect the completion rate metric and task duration metric.
Whether it’s a tutorial via a video conferencing app, a PDF instructional guide, or a short online course, giving new users the support they need should boost the results of your usability metrics.
Remove unnecessary steps from processes
Today’s customers expect an optimized experience that requires as little input as possible. Removing unnecessary steps from processes should result in higher customer satisfaction and efficiency scores.
3 Benefits of Usability Metrics
You should work on improving your usability metrics because it can give you certain benefits — here are the most important ones.
1. You can maintain a record of progress between releases
Just because your product’s usability metrics looked good at launch, it doesn’t mean these results will continue to the next release.
Running usability metrics allows you to maintain a record of progress between releases. With tools for real-time reporting analytics, monitoring and adjusting your product’s usability is easier than ever.
2. They give you room to examine your competitive advantage
Collecting usability metrics gives you a benchmark to evaluate your competitive advantage over rivals. You’ll need to ensure you ask the right analytics questions, but having this benchmark allows you to stay one step ahead and provide a better product with ongoing support.
3. They help you with your stop/go decision before launching
Getting usability feedback from users helps you decide whether or not the product is ready for launch.
Negative feedback might indicate there’s more work to be done, whereas positive feedback might indicate your product is ready.
Usability metrics are crucial for getting user insights that will help inform better decisions about building and improving your product. Changing your design process could increase revenue when you better understand everything that’s happening with your product.
