Scenario and Tasks
Introduction
System Analysis & designing is a very important subject domain related to
Information systems. Information systems’ durability, Validity, efficiency & accuracy
depends on how well the system investigation & designing activities are accomplished during
the system development life cycle. Learning & making use of the best tools such as Entity
Relationship Diagram, Data Flow Diagram, Flowchart and Unified Modelling Language
Diagrams for aforementioned activities are very much essential for a system analyst.
Clear understand ability of Software Development Life Cycle model stages &
unique duties assigned to those enables software development team to maintain product
quality, track progress, project budget and the nature of the product, according to higher
satisfactory level. Selecting the best Software development process model for an information
system project is crucial since success or failure of the product can be decided by the process
model & its systematic approach.
When the subject domain is concerned it is always imperative to attention to be paid in
applying creativity and innovation for system designing in a manner that modern world man
kind’s requirements are supported by considering not only how their lives are further
improved with sophistication but also focusing on how does ethical and professional issues
are mitigated as much as possible.
Scenario
“Meda Midula” is a hotel consisting of 100 rooms needs to computerize their manual Hotel
Reservation System. The systems analyst who was assigned to this project has visited the
Hotel and he has gathered the following information about the system. The following text
describes his findings.
The 100 rooms available are categorized into different room types and each room type has
different rates. The number of rooms in different types and the corresponding rates are as
follows:
Room Type Room No. from/to Rate/Night;
 Single 1 to 60 Rs. 1000

 Double 61 to 89 Rs. 1800
 Suite 90 to 100 Rs. 5000
A Customer can reserve a room by calling the hotel receptionist. The receptionist will answer
customer’s queries regarding the room types, room rates, modes of payments available and
any discounts the customer is entitled to etc. The receptionist will then take the following
particulars from the customer, if customer wishes to proceed with the reservation.
Customer’s name, contact address, Country, Sex, Type of accommodation, the period of
stay, expected check in date.
Subsequently the receptionist will check the room availability. If a room is available, the
customer is informed about the room availability. If customer accepts the reservation, a room
number is allocated at the same time. The customer is also informed if a room is not
available. A customer can cancel the reservation at any time. It can be done by calling or by
sending a fax. The receptionist is also responsible for handling the cancellations. When the
customer checks-in at the hotel on the reserved date, the receptionist will obtain the
customers desired mode of payment. The customer may be entitled to a discount based on the
payment mode selected. The different payment modes and their discounts are as follows:
Payment Modes Discount
 Cash - No discount
 Traveler’s Cheque - 2% e.g. AMEX, Cooks etc.
 Credit Card - 3% e.g. Diners, Master Etc.
 Company - Depend upon the company (E.g. NEC 12%, IBM 10% etc.)
The Customer can checks-out from the hotel at any time by informing the receptionist. The
receptionist will immediately inform the billing Clerk to handle the billing. The details about
the Payments such as discounts given, company name, kind of traveler’s cheques used, and
credit card details etc. are preserved for any future reference.
If the customer needs to extend the stay he/she may do so by informing the receptionist.
Receptionist will check the room availability and extension is accepted if rooms are available.
Imagine that you have been assigned as a system Analyst by the e-Builders Systems
Development PLC to prepare a fully descriptive documentation comprised of Hotel
Reservation System analysis & designing information. In order to begin with user
requirement gathering & system environment analysis you are free to choose any higher
educational institute to conduct interviews & site observations. In prior commencing with
system investigation activities proper approval should be given to you by authorized officials
of the tourist category hotels that you are visiting. In order to get the approval you can
forward ICBT Campus official request letter to them.

General Guidelines for Students
1. With knowledge gain from the case study/Real world Scenario, analyse the facts
carefully and try to understand the association between each entity in the
environment. Also identify the data that is, needed to be stored for each entity and its
relationships. Any applicable assumptions made, should be clearly mention with
proper justification.
2. Final report should be in professional manner and with proper formatting.
3. The student needs to give priority in designing the software product of the
information system.
4. Organizational visits & information gathering can be done in both individual and
group basis which not exceeding 4 members per group.
5. Before organizational / Work site visits students are expected to obtain ICBT official
letter requesting the relevant company for conducting information gathering work
within their premises.
6. Please note that students are expected to maintain backup copies of work in different
media. Due to any hardware, software malfunctions or virus attacks, assignment
deadline will not be lifted.
