What's the System Usability Scale (SUS) & How Can You Use It?

当我想到易于使用的产品时，我会想到我的Apple Airpods。

在情况下，它们通过蓝牙技术连接到我的Apple设备，因此我可以收听音乐，接听电话并在笔记本电脑上工作，所有这些都具有高质量的质量，并且没有绳索缠结。

I tell people how easy my AirPods are to use whenever they ask me about them, and after I did a little digging, I learned how important usability is to customer satisfaction. Think about it: If a product or service was hard to use, you probably wouldn't like paying for it very much.

测试可用性是开发和改进产品的重要组成部分。在这篇博客文章中，我将研究可用性，以及如何使用系统可用性量表（SUS）进行测量。

在创建可用的产品或系统方面，没有一个可用性的一个方面，而是可以使其成为这样的因素的组合，包括：

• Efficiency: How fast someone can use it
• 直觉：有人能毫不费力地理解它
• Ease: How easy it is to use
• Satisfaction: How much a user subjectively likes or dislikes using it

User-focused design helps product managers, designers, and engineers prioritize the user experience to help make the end-product as usable as possible. User testing over the course of product development can help make usability improvements that will benefit the end user, and the System Usability Scale (SUS) is a form of user testing you can employ.

What's the System Usability Scale (SUS)?

TheSystem Usability Scale（SUS）是10个项目利开特式量表调查表提供了一个信息，可以探讨网站，软件，硬件，移动设备和其他技术应用程序的易用性（或缺乏）。bob电竞官方下载

SUS由约翰·布鲁克（John Brooke）于1986年创建，以衡量电子办公系统的可用性，但现在已应用于各种基于Web或技术的应用程序，以衡量其用于改进的容易或困难。

系统可用性得分问题

The SUS consists of the following10 questionsthat can be answered on a five-point Likert scale of "Strongly Disagree" to "Strongly Agree." In this example, we'll reference a website in the context of the questions, but these can be asked about products, websites, applications, hardware, or software.

1.I think that I would like to use this website frequently.

2. I found this website unnecessarily complex.

3.我认为这个网站易于使用。

4. I think that I would need assistance to be able to use this website.

5. I found the various functions in this website were well integrated.

6. I thought there was too much inconsistency in this website.

7. I would imagine that most people would learn to use this website very quickly.

8.我发现该网站非常笨拙/尴尬。

9.使用此网站，我感到非常自信。

10. I needed to learn a lot of things before I could get going with this website.

These questions ask, with a variety of different phrasing and nuance, questions about how easy or difficult it is to use whatever tool users are being surveyed about. Next, let's explore the benefits of using the SUS.

Benefits of Using the SUS Score

1.它提供了一个简要usab的快照le or unusable your system is.

By looking at a single number, anyone can understand how users feel about the usability of whatever you're evaluating.

2. It's easy to use, at scale or with a small number of respondents.

SUS surveys can be administered in-person, via email, or across a variety of other media to get the answers needed to evaluate the score.

如何解释SUS分数

1.适当评分您的答复。

One fault of the SUS score is how complicated it is to interpret: You must add together the scores you receive, then multiply the sum by 2.5, to make the scores on a scale of 0-11. The score doesn't represent a percentage, but a sum of these new numbers.

2. Evaluate the score in context.

According toUsability.gov, a SUS scoreabove a 68is considered average, and anything below is considered below average. Alternately, you can group the number of scores you receive to determine what percentage of respondents gave you a high or low score.
