Non-functional requirements capture conditions that do not directly relate to the behavior or functionality of the solution, but rather describe environmental conditions under which the solution must remain effective or qualities that the systems must have. This includes requirements related to scalability, performance, security, availability and the information architecture and presentation of the user interface.
