A survey for quantifying feedback from assessments of usability
The way people feel when using a product is just as important as how they use it. To understand how a design is doing, you need to get both people's opinions and facts. The System Usability Scale (SUS) is a free tool designed by John Brooke for Digital Equipment Corporation. It uses the Likert Scale, which asks people to rate each question on a five-point scale from "Strongly Disagree" to "Strongly Agree." This is a good way to compare different designs and works well in many areas.
To calculate the SUS score, the user response for each odd-numbered item is subtracted by 1. For even-numbered items, the user response is subtracted from 5. This will give all the numbers a range of 0 to 4, with 4 being the best response. Finally, the new answers are added up and multiplied by 2.5. If the total score is over 68, it is considered good. This tool is incredibly useful for making sure that the design of a product is user-friendly and efficient.
