[Year 12 SofDev] SD2011 exam - C3

[Mark KELLY]

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?
