Executive summary
This report presents a discussion on the system analysis process of the proposed information system for
Allure Investments Pty. Ltd. which is a company specializing in management of client portfolio’s and
active investments on the Australian Stock exchange on behalf of the clients. The company is in need of
an information system that will help them to manage day to day activities while maintaining the data
generated through these activities. The document describes the scope of the proposed system and
presents a feasibility analysis to determine whether or not the proposed system is a viable option for the
company or not. Functional and non-functional requirements of the system are described and all the
system constraints necessary for the implementation of the system are discussed. Unified Modelling
language is adapted for the proposed system as it makes it easier to analyse and document the system
through use of use case diagrams, context models and functional models. These models can then be
used to make the design document for the proposed system.
System description
The current system in use by the company is a manual system which is making work very tedious thus
limiting individual productivity of each employee as well as adding redundancies in some roles. The
proposed system will be designed to solve this problems by making it easy for employees to perform
various tasks. The system will be a web based system thus will require a web server to be deployed. This
will enable remote access of the system for both employees and customers wishing to access their
portfolios.
Scope
The proposed system will be developed within the required time frame and allocated resources. A
project plan defining the project schedule, resources and budget will be followed entirely throughout
the project life cycle. The development team will ensure each stage of the project development life cycle
is followed and all goals are achieved to make sure the final product meets all functional and no-
functional requirements.
Feasibility analysis
Feasibility analysis is done before the project is started to determine whether or not the project is
economically and technically feasible for the company. This involves carrying out a study on the
resources and the time it will take to implement and deploy the system and comparing it to the time it
will take for the system to start returning a return on investment. For the proposed system, there are
many factors that limit the current system thus warranting need for a new system. These factors
include;
 The current manual is tedious for employees for example the portfolio managers thus limiting
their productivity and ability to handle multiple portfolios.
 The current manual system does not give access to a client thus a client has to rely on the
concerned parties to access their portfolios.
 The current manual system is creating redundancies in different roles within the company thus
leading to a higher budget on salaries.

The proposed system will be implemented to make work easier thus improving productivity of the
employees. This means the company will be able to handle more clients and more transactions because
the system will make it easier to track client and information and market information thus leading to
high profits for both the clients and the company. The system will also eliminate redundant roles thus
reducing the amount of money used for salaries.
Based on the analysis presented above, the system is both technically viable and economically viable as
it’s expected to make a return on investment within a short period of time.
Requirements specifications
Functional requirements
Functional requirements are what the end user expects from the system. These are requirements
described by the end user on how he or she should use the application to achieve various goals defined
within the scope of the system. For the proposed system, the functional requirements can be defined in
terms of the different type of end users using the system;
Portfolio-manager
As a portfolio manager, I would like to;
 Access and review client portfolios at any time.
 Buy and record stocks for a client. I should be able to specify the stop-loss and the selling-price
for each buy. The system should notify me if the stock reaches a stop-loss or if the stock reaches
the selling-price.
 Sell and record client stocks
Account manager
As an account manager, I should be able to;
 Add a new client after conducting an interview with the client.
 Assign a portfolio manager to a new client
 Add and update the yearly funding level for a client
 Review portfolio manager performance.
 Place sell orders issued by the portfolio manager
 Receive and record dividends received from different companies.
 Report client positions.
Fund manager
As a fund manager, I should be able to;
 Access and maintain buy and sell orders for each client
 Access and maintain information regarding buy and sell parcels
 Access and maintain information regarding dividends.
Client
As a client, I should be able to;

 Access and check my portfolio balance
 Deposit funds to my portfolio
 Generate reports on my buy and sell orders
 View my profile
Non-functional requirements
Non-functional requirements specify the constraints that the system should follow in order to achieve
different functional requirements. The following are the non-functional requirements for the proposed
system;
 Performance- The proposed should be able to perform all actions using the least amount of time
possible.
 Availability- The proposed system should be available at all times and should be accessible from
any remotely from any location.
 Security- This is perhaps the most critical non-functional requirement for the proposed system.
The system should be able to ensure security at all levels and at all times considering the nature
of the application since the data generated by the system is critical and sensitive thus falling on
a malicious user could lead to losses.
 Robustness- The proposed system should be robust meaning it should continue operating
despite encountering an error.
Assumptions and constraints
The proposed system will be implemented based on the following assumptions;
 The system will be implemented as a web application allowing remote access for both
employees and customers.
 The system will use third party applications like payment merchants to take advantage of
existing solid APIs that will make the development process easy.
 The system will be deployed in a private cloud instead of deploying the web application in an on
premise server room.
