Q1 [Marks 10]
“[FONT="]During the construction of a motorway link road, for shifting an Interchange 5 Km ahead of its current location after it has already been built, it is going to be very costly. It could be easily fixed if realized earlier.”[/FONT]
1) Create an analogy of the software development phases with above scenario.
2) Also mention the most suitable and worst phase (justify your answer with solid reasons in each case) for a “needed change” in case of software development regarding cost and efforts.
Q2 [10 Marks]
Draw the use case diagram of the following scenario
As System Analyst at Pakistan Railways, you need to model a Ticket Selling System for Terminal computers (TSSTC). Reading the Functional Specification of the system, you draw the following conclusions:

Q2 [10 Marks]
Draw the use case diagram of the following scenario
As System Analyst at Pakistan Railways, you need to model a Ticket Selling System for Terminal computers (TSSTC). Reading the Functional Specification of the system, you draw the following conclusions:
- The main purpose of TSSTC is to use it for searching the “Train Timings” and purchasing the train tickets.
- TSSTC consists of touch screen as an interface between passenger and system, credit-card reader and a printer to print tickets.
- Each passenger uses available interface to search the available routs and train times from which he selects one train.
- After he selects the train, the terminal screen displays the available seats in that train.
- The passenger selects the seat and the system prompts the total fare.
- The payment is then made by credit card (using credit-card reader).
- The system confirms the payment. If the payment is not confirmed, system displays an error message and transaction is terminated.
- If the payment is confirmed, the ticket will be issued and printed by the printer, from where the passenger collects his ticket.
