I have some doubts about non functional requirements in a web app. Are quality attributes non functional requirements? Also, these are all examples of non functional requirements?
- The system should have a score >= 80 in PageSpeed
- All network transactions should be encrypted
- The users need to login to the system to access the administrator panel
- 90% of new users should be able to perform the main tasks (task 1 and task 2) of the system without any error the first time they perform the task
- The system should be compatible with the main browsers
