[Year 12 SofDev] SD2011 exam - C3

[Harper, Glenda J]

The only way I could see to respond to this would be the functional requirements that there is data input and information output. The flows into and out of the system indicate that this has to happen.

C3 seems odd to me.

"Kirsten will include a context diagram in her SRS.
State two functional requirements of the Parking Infringement Monitoring System (PIMS) that this context diagram would show."

1. The context diagram would show no functional requirements. A context diagram doesn't show any processes: the system is a black box.  The CD will only show data flows between the system and its external entities. These data flows might suggest FRs hidden in the black box, but they in themselves are not FRs.

2. If we look at the UCD, providing functional requirements is easy enough, but what about the examples?
The FRs are shown as use cases and are quite specific (e.g. Print parking ticket); I don't see how you can provide an example of printing a parking ticket.

3. One of the main FRs is to take the car arrival/departure event data from the RDL and calculate overstays - but this calculation is not included in the UCD.

How did you guys respond to this question?
