资料：Early Experiences
If you've communicated a positive initial impression and customers decide to explore your product, can they discover the features and functions that help get them up to speed? Does your interface provide clear, streamlined paths free of unnecessary instructions, distracting visual elements, or unneeded features or functionality? Finally, how well does your product help customers get the benefits they want, or even lead them to benefits they were unaware of?
Testing helps determine if customers find the terminology clear and jargon-free; whether the page and content is organized logically from their perspective; if processes-such as registration, checkout or upgrading-are efficient and easy to use; and if it's clear how to cancel a process or navigate to a specific function or location.
Maturity
Over time, discovering shortcuts and advanced functionality will help mature customers do their jobs more quickly. You'll want to test how these options are communicated and ensure that they address the needs of these customers without impacting the experience of other customers.
Unless you test with actual users, your product team won't get a true perspective about what your product is like to use by the people who matter most the users themselves. This may seem obvious, but in many organizations, approximate customers-such as salespeople-are sometimes used to review products. After all, they have a lot of customer contact. But salespeople don't have the same motivations or context as customers. At best, this approach is risky. When you test with real users, usability tests ensure that all product stakeholders get a realistic, honest view of your product's effectiveness.
If you have never watched a customer use your product, you might be in for a surprise. "Obvious" product assumptions may be challenged, or you might find that customers think differently about what value means to them. Whatever you discover, you'll unearth information to develop products that are more likely to be ones that your customers value.

Testing has many benefits. Which of the followings is NOT one of them?

A.To determine whether the product is user-friendly.
B.To see if the process is simple enough for users to understand.
C.To learn about users' perspective.
D.To cancel a process or navigate to a specific function or location.
