Question No. 1
Consider VISA System of PAK Embassy that stores the personal details of the VISA requester along with other details e.g. job history, abroad traveling history, bank account details etc. However, the system also queries for Criminals database system (maintained by local government) to verify about any criminal record against that person. For this purpose VISA System uses the CNIC number of that person to retrieve the crime history (if any).
From the above case study, identify the Internal Logical files (ILFs) and External Interface files (EIFs) with respect to VISA System. Marks 7

Question No. 2
For a certain requirement specification note the following:
Nnf = Non-functional requirements = 15
Nf = Functional requirements = 35
Nui = number of requirements for which all reviewers had identical interpretation = 10
Calculate the “Lack of Ambiguity” in the requirements given in specification. Marks 8
Answer:
The numbers of requirements are calculated as:
nr = nf + nnf
nr = 35+15 = 50
Now lack of ambiguity in the requirements is calculated as:
Q= nui/nr
= 10/50 = () Answer

Q 1

The numbers of requirements are calculated as:

nr = nf + nnf

nr = 35+15 = 50

Now lack of ambiguity in the requirements is calculated as:

Q= nui/nr

= 10/50 = (0.5)
