当然，最好的指标是用户的满意度。
但是，您知道GUI可用性测量的哪些指标？
例如，常见指标之一是执行操作的平均点击次数。
您还知道其他哪些指标？
Jakob Nielsen撰写了几篇有关可用性指标的文章，其中一篇名为《可用性指标》：
The most basic measures are based on the definition of usability as a quality metric:
-
success rate (whether users can perform the task at all),
-
the time a task requires,
-
the error rate, and
-
users' subjective satisfaction.

Here is a simple pre-launch check you
should do on all your web
applications. It only takes about 5
seconds and one screeshot

| Q:"What percentage of your interface contains stuff that your customers
want to see?" |
If you answer a, or b then you might
do well, but you’ll probably get blown
out of the water once someone decides
to enter the market with option c.
并非严格的可用性，但是我们有时会测量GUI和后端代码的比率。 提醒管理人员，这是重要的，尽管功能很重要，但GUI也应按比例分配预算用于用户测试和学习。
我只是查看用户要去的地方以及他们(实际)在屏幕上要去的地方，我使用Google Analytics(分析)中的数据进行此操作。
