当然,最好的指标是用户的满意度。
但是,我们知道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。
我们还知道其他哪些指标?

解决方案

回答

Jakob Nielsen有几篇有关可用性指标的文章,其中一篇标题为"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.

我只是查看用户要去的地方以及他们(实际地)在屏幕上的去向,我使用Google Analytics(分析)中的数据来完成此操作。

回答

并不是严格的可用性,但是我们有时会测量GUI和后端代码的比率。提醒管理人员,这是重要的功能,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。

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?”

  
  
  10%
  25%
  100%
  
  
  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.
