Every designer’s biggest concern is devising a product that will be easy and satisfying to use but measuring User Experience is not without its challenges either. However, numerous qualitative and quantitative methods can help us determine the quality of our UX design including quite a few metrics that can help us shine a light on the success of our project.
However, we still need to understand why and how people use products before we set out to further analysis.
Measuring Product Usability
What do we mean when we say that the product is usable? First, we need to define the users as people that products are designed for, to help them complete certain goals in certain use cases. User satisfaction, however, is the main aspect of usability because not only does the product need to be functional and easy to use, but it also has to entice a sort of joy in a user.
That said, let’s talk about the most common metrics that are often used to determine the quality of our UX design.
What is the Task Success Rate?
One of the most common and most easily understood UX metrics is by far task success rate. It shows us the percentage of participants that complete a task. Tasks have to be clearly defined to get valid results. Simple actions such as adding items to shopping cart or completing the signup process can be successfully tracked via this metric that relies on a simple formula: number of successful attempts/total number of attempts = TSR. The biggest flaw of this metric is that it does not explain why participants fail to complete tasks or how well they perform them.
Task completion time
As the name itself suggests, this metric measures how much time a user needs to complete a task. Simply put, the less time a user needs to complete a task, the better.
The retention rate shows us how many users continue to use our product over time. However, we must predefine the entire set of customer activities on our website to be able to precisely determine the retention rate.
This metric gives us an insight into the percentage of users that take the desired action on our website, be it completing a signup process, subscribing to our newsletter, or making a purchase.
What is Error Rate?
The error rate is the percentage of bad entries that users made. High error rates usually mean there is something wrong with product usability.
Measuring Customer Satisfaction
There are numerous ways we can measure customer satisfaction, including asking them to fill in satisfaction surveys or use some of the following scoring methods: customer satisfaction score, net promoter score, customer effort score, track social media mentions, etc.
When we are talking about the set of predefined usability principles or standards and conventions that have been observed and tested over time, we are talking about heuristics. And in heuristic evaluation, expert evaluators try to identify usability issues and rate their severity, which helps UX designers act quickly and solve the problems.
Quantifying User Experience
There are a few well-recognized frameworks including The AARRR framework, The RARRA framework, and the CX index that all rely on different indicators and metrics when trying to measure the success of products or features, consumer’s interaction with businesses, customer loyalty, etc.
Measuring user experience is fundamental for various businesses and is something experts pay the utmost attention to.
