# S10 - Lightning Pull Requests

### **Why is this a symptom?**

This symptom refers to a high number of pull requests that are submitted and merged quickly, without adequate code review and testing. 

Lightning pull requests can be an indication of a lack of established code review processes, lack of attention to code quality, or lack of team cohesion. 

Lightning pull requests can lead to poor-quality code being merged into the main codebase, increased risk of defects, and decreased code maintainability. It can also lead to decreased developer productivity and a lack of accountability among the team. 

Lightning 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, increasing time dedicated to review and testing, and paying attention to code quality best practices.
