Case Study: MNTC Bus Reservation System

Muscat National Transport Corporation (MNTC) has buses for various destinations originating from Muscat. The Corporation has currently about 1000 buses spread over 50 routes operating from Muscat to various places. Of them, 700 are regular, 200 are semi-luxury, and remaining are super deluxe buses. The seating capacities are 48, 42 and 36, respectively.
It has a bus reservation system which works as detailed below:
MNTC requires the passengers to book their seats atleast one week in advance. The passengers fill up a form with the details like: date of journey, starting point, destination, number of seats, concession required (if any) and departure time of the service. If seats are available, the system provides a lot of enquiry services to help the passenger take a decision. If seats are not available, passengers are informed, given a priority and put in a waiting list.
Two seats are reserved for VIPs and/or emergency quota. However, if nobody turns up for the travel, upto half an hour before the departure, the seats are allotted to those in the waiting list according to priority.
Concessions are given in respect of students during summer vacation. Students need to pay only 50% of the actual fare.
Employees and their eligible family members may travel free once a year, by producing the appropriate identity cards. The system verifies that the total distance travelled by such a person does not exceed 3000km for one year period.
The system provides a facility for cancellation. The cancellation policy is such that that 10% of the fare should be forfeited if the cancellation is done atleast two days prior to the journey. 20% should be forfeited if the cancellation is done one day prior to the journey but not more than two days. 25% should be forfeited if done prior to 8 hours of the departure and 40% if done less than one hour of departure of the bus. In all other cases the full amount is forfeited.
The reservation fee of OMR 5 is always non-refundable.
If the passenger wants to postpone his journey, it can be done for a maximum of one time subject to availability of seats by the same route at no extra cost.
The system maintains a database of various routes originating from Muscat and the fare by each of them for various categories of buses to various destinations.
Frequently the Corporation may revise the fares and system should accommodate this also. Assume that more than one counter is simultaneously active for reservation/cancellation.

Based on the above narration, do the following tasks:
1. Produce the following for the above mentioned scenario:
a. Context diagram
b. Level 0 DFD of the system
c. Level 1 DFD of one of the processes identified in your Level 0 DFD.
d. Decision Tree
2.
a. Identify a suitable SDLC model for the development of MNTC Bus Reservation system.
b. Justify your selection with appropriate reasons
3. Assume that you are the system analyst handling the project of the MNTS Bus Reservation system. You are going to conduct an interview for gathering more information about the system with the intention of improving it. What questions would you ask them? Document any five of the questions along with their expected answers.
4. Prepare a well-designed input form for any one of the following processes in the system:
a. Cancellation
b. Reservation
c. Postponing Journey
d. Employee Availing free travel
e. Student Availing concession
The form should have minimum four valid sections.
