REQUIREMENT ANALYSIS AND MODELLING
Part A
Executive Summary
The purpose of this report is to reflect on the requirements those are necessary for the
development of this system. The purpose of this report is to efficiently analyze the requirements
necessary for the development of a successful and efficient system that can contribute in the
effective deployment of the VCI and provide better services to its consumers. The report is
divide in two divisions Part A comprised of the theoretical presentation of the system analysis
and Part B comprised of the practical works demonstrating the visual presentation of the
functions necessary for the system. The proposed methods and systems will allow the
organization to develop a sophisticated system that can contribute in the development of an
efficient system.
Introduction
Technology has been revolutionizing every sector in the present world and so is
influencing the education sector. This report emphasizes on the demonstration of the systems and
functions those are necessary for managing the operational activities in the VCI. The case study
states that the VCI (Virtual Child International) has been virtual world for the children and that is
helpful in enhancing the knowledge of the children through demonstrating the virtual world. The
employees of the VCI supposed to be backing up the system called VCI Park behind the scenes
and contribute in the providing guidance to the children and the members connected with the
developed system. The proposed system is comprised of many levels of the authorization
allowing the individuals connected to the system to have different levels of the authorization
with unique credentials.

REQUIREMENT ANALYSIS AND MODELLING
A draft has been proposed in this report regarding the development of the VCI system
and demonstrating all the essential aspects those are necessary for the development of a
successful and efficient system for supporting this model. Theoretical aspects and practical
works have been proposed in this report including the demonstration of the functioning of the
system.
Problem
` The problems being addressed in this system can be demonstrated as:
Manual operations
Most of the functions of the proposed system were being operated manually and it could
lead to certain human errors including redundancy, calculation error, less accuracy and the
attempt will be driven for automating the entire system. It will allow the park rangers, members,
and other internal stakeholders to perform the necessary operations in an efficient and effective
manner. This would enable the park rangers to guide the members more efficiently and
effectively.
Payment System
Another identified issue in the previous system was the payment system as the users had
to provide their details again and again and so the attempt will be driven for improving the
existing payment system that can allow the users to make the payment in different ways or with
the saved details.

5
REQUIREMENT ANALYSIS AND MODELLING
Scope and proposed System Requirements
The scope of the proposed system will be to automate the entire system and allow the
users to avail better and automated services those can alternatively result in the positive outcome
of the system. The system will eliminate the existing problems with efficient functionalities
through providing a portal that can allow the individuals to perform daily operational activities in
efficient and effective manner. System objectives can be listed as:
 To establish a system that is highly efficient and accurate
 To manage the manual operational activities automatically
 To allow the users to avail advanced services
The constraints of the system can be listed as:
 The system development will take three months to be effectively launch for the real
world application
 The budget of the system development will not exceed $ 20,000
 The system will be immune to bugs and glitches while launching phase
Data collection techniques
There are many ways for the collection of data however; for this system questionnaire
distribution can be recommended as the best approach for the collection of data and information
related to the proposed system. The stakeholders will be distributed with a set of open end and
close end questionnaire that will allow the stakeholders to put front their perspective of the
system.

REQUIREMENT ANALYSIS AND MODELLING
System Requirements
Functional Requirements
The main functional requirements for the delivery of the proposed system can be listed as
following:
 The data handling could be delivered in an efficient manner through the user themselves.
 The user would be able to connect with the system in smooth manner
 The payment system should be incorporated within the system allowing the users to
select the favorable payment system for the users
 The access control and authorization level should be separately designed by different
group of the users
 The validation system should be embed within the system for monitoring purpose
 The data modification system should be available for the users in manner to update the
system whenever there is the requirement of the system.
 Proper and easy user interface should be available allowing the users to be specific while
selecting an option
 The developed system should be highly secured as the very personal information will be
collected related to the user
 The system should be capable of delivering all the necessary operational activities in an
automated manner
Non-Functional Requirements
Reliability: The proposed system should be good enough that the parents, guardian, and
the children could rely on it and perform necessary operational activities. The system will be out

of the bugs and glitches and hence, the accuracy will be maintained and the users could thus, rely
on the system.
Availability: The system would be available for the users for 24*7 till the use is
connected to the system or logged in the system. Thus, the users could avail the services at any
time whenever they want to connect with the system.
Maintainability: It technician committee will be established for monitoring and auditing
the system and identify the bugs and glitches those might affect the entire functionality of the
system and the services will be maintained and managed in efficient and effective manner.
Security: The personal and sensitive information are being collected for making the
system much accurate and efficient and so the system needs to be highly secured and the user’s
data and information needs to be managed in secured manner.
Usability: the system will have application for every user s and all the internal
stakeholders would be allowed to avail the services from the system and assure that there are
separate sectors for the users to utilize the services.
User Interface: Easy and effective user interface will be necessary for the effective and
efficient deployment of the system. A training section can be embedded within the system for the
users entering and using the system for very first time.

Recommendations
 System can be integrated with the cloud services through accessing a portal and allowing
the users to be connected with the system.
 The system can be developed from scratch can be another efficient approach for the
system development
 COTS can also be utilized for the development of the system

The above matrix effectively proposes the efficiency and effectiveness of the developed
system can be maximized through utilizing the cloud services and accomplishing all the
objectives of the developed system.
Cloud services will be highly efficient and effective in managing all the operational
activities embedded within the system and the cost spent on the successful implementation of the
system will also be decreased. These services will be managed and maintained by the third party
and thus, maintenance expenses will also be restricted for some extent. The security and privacy
of the data and information of the individuals was another requirements of the system that can be
accomplished through utilizing and executing the project on the cloud platform. The system also
needs to be available for the users for 24*7 hours and that is what an organization can achieve

through embedding the cloud computing within the existing system of the organization and so, it
can be stated as the best and efficient approach for the development of the VCI park system.
