there is something I need some input for…
we have to specify non-functional requirements for every quality characteristic, e.g.:
Main Characteristic: Efficiency
Sub Characteristic: Runtimes
REQ_1: every response to a user-request occurs in less than 250 ms.
REQ_2: the server-startup needs less than 15 seconds.
So, for Efficiency there are some ideas and things you can meassure. But what about the other characteristics like Usebility or Scalability and so on. I have no big ideas, and the requirements should mostly be measurable, right?
Do you know a list of examples or know how I could define specific requirements for all the sub characteristics? Thank you.
