Business Thinking for Designers

Rating scales and rubrics
Simply put, a rating scale is a set of categories with an 
associated value for a feature, a product, or an experience. 
Common in surveys, psychological assessments, or education, 
rating scales are also popular for business measurements like 
Net Promoter Score or Customer Satisfaction.

Rubrics, on the other hand, are the criteria used to evaluate 
overall performance. They consist of a rating scale and a 
detailed description of the characteristics for each level of 
performance. These descriptions focus on the quality of 
performance. 
A common measure of usability is how well users can complete 
tasks. Here’s an example of a rating scale with rubrics to help 
determine the quality of task completion:
01. Does not complete task
02. Successfully completes task with a lot of support
03. Successfully completes task with some support
04. Successfully completes task with minimal support
05. Successfully completes task as expected
An effective way to monitor and track usability or accessibility 
improvements over time is to present the status of these 
ratings through a scorecard.
