There are many use cases for BrowserStack Code Quality rating. Few of the use cases are explained here. One of them is comparing the overall quality of different software projects and repositories
A second use case is tracking the quality of one software repository over time. The overall rating gives a very quick overview over improvements or deteriorations in the quality and helps to establish a continues quality improvement process. Even for non software developers that makes software quality understandable, and helps to track certain projects or software suppliers over time.
As a third use case, the BrowserStack Code Quality rating enables development managers to easily allocate resources. The way the rating is calculated out of four sub-metrics it provides insights into what part of the development team needs training or additional support. If the design rating is bad an additional software architect might be required. If the code issues or metrics rating is bad, training no certain programming principles might be helpful. A bad duplication rating is in indicator for suboptimal code organization, documentation or team structure.
