S9 - Unreviewed Pull Requests

This symptom refers to a high number of pull requests that have not been reviewed by other team members.

Why is this a symptom?

This symptom refers to a high number of pull requests that have not been reviewed by other team members.
Pull requests are a way for developers to submit their changes for review and merge them into the main codebase. Unreviewed pull requests can be an indication of a lack of established code review processes, lack of time dedicated to code review, or lack of team cohesion.
Unreviewed pull requests can lead to poor-quality code being merged into the main codebase, increased risk of defects, and decreased code quality and maintainability. It can also lead to decreased developer productivity and a lack of accountability among the team.
Unreviewed pull requests can be considered a symptom of the development process, indicating that the team may need to focus on improving their code review processes and increasing time dedicated to code review.
