Sec;on 3: Specific requirements • This sec;on of the SRS should contain all of the so,ware requirements and specifica;on. – This is the “meat” of the SRS; all UML and UI diagrams go in here! Expected input/output behaviour is detailed here. • At a minimum, it should include descrip;ons of – All interfaces to the system • Every input (s;mulus) into the system • Every output (response) from the system – All func;ons performed by the system • validity checks on inputs • rela;onship of outputs to inputs • responses to abnormal situa;ons (e.g., overflow, error handling)
Sec;on 3: Specific requirements • Input and output defini;ons should be consistent among UCs, func;onal specs, state machines, and UIs. • Should be at a level of detail sufficient to enable: – designers to design a system that sa;sfies the specifica;on – testers to test that the system conforms to the specifica;on • There are different ways of organizing Sec;on 3 – We’ll look at two approaches briefly
