I sent out an email earlier reminding our developers that, the use of
the word, 'Shall', in your derived requirements should not follow over
to your functional requirements. When writing functional
requirements the word, 'Must', is used to describe the function a
derived requirement must do.
Derived = System Shall be requirement
Functional = System must do requirment
It was sent back by one of our Seniors that, that was wrong and that shall should be used in every requirement.
Am I wrong here and Shall should be used in every requirement. I haven't been able to find anything to back that up.
