How do you capture non-functional requirements?
We capture non functional requirements by recording their metrics (sums or ratios), either manually or with digital tools that trace unique identifiers. For example, a kitchen manufacturer manually records maximum volume for a frying pan, and a webmaster uses Google Analytics to track visitors to his/her website.
