Three Definitions of Customer Experience Testing

Traditional enterprise testing seeks to answer whether applications and technologies behind a service launch will perform as intended. Customer-experience testing moves beyond that exercise, going further to evaluate whether the people working with the systems and the business processes defined for them are likely to prove successful

Customer experience testing is the testing of a product or service from the perspecitive of a customer.

When a product or service goes live, the customer experience is critical as it is a major factor in the take up and retention of the product or service. Unlike technical testing, customer experience testing is about customer perception, which can differ from reality. This is based on customer expectations and emotions as well as physical performance and processes.

From Customer Experience Testing glossary entry

Customer experience measurement or testing is a well established method to discover issues in the experience of a product, website or service. A customer experience issue is identified as brand value, information or functionality that is hard to find, use or learn.
In our testing, these customer experience issues can be measured by: perceived value, time to complete each task, human errors made during the test and the human reaction to any tasks in the test.
