Part 1: Planning Phase: -
Project identification:
Project Title: Information System Management.
Project Description:
Mr. and Mrs. Khan took over their family business in Riyadh. They are producing
handmade toys and deliver it across the country through a delivery service. They have many
loyal customers across the country. Few of their customer order their product by Email and
some of them are using their phone to get their product. But at the same time, they are facing
several issues. They find out that their competitors using an advanced system that provides
the same products in less price and provides better delivery options. Mr. and Mrs. khan
believe that with the help of a new information system, they can make more profit and offer
better delivery options among users.
Currently, they are using a manual system where a staff take customer phone call and
write down their details in the spreadsheet such as customer name, phone number, email and
address. Then he/she goes to the shop and find the product, pack it and send it to the delivery
partner. In this scenario, customer phone is the trigger the order process. For the payment,
they are taking credit card details from the customer over the phone.
From a few months, they are facing a new problem that in holidays they are unable to
maintain the workloads and its impact on the business. Few challenges are discussed below:
 The orders are going to the wrong person.
 Orders are not delivered at time.
 Unable to handle multiple customers at a time.
 Can not provide handwritten receipt to customers.

3SYSTEMS ANALYSIS AND DESIGN
To eliminate the above problem Mr. and Mrs. Khan decided to implement a new system that
can automate the Toys ordering system. Mr. and Mrs. Khan decided to employ a system
analyst to provide few courses of actions.
Feasibility studies:
This section of this project includes the Technical Feasibility, Economic Feasibility
and Organizational Feasibility that can determine the strategies. Process and design.
Technical Feasibility:
It can measure the possibility of a specific technical solution and technical resource
availability. This study is helpful to determine the solution is practical or not. And the
importance of implementing new technology in the existing system. A system analyst
develops a prototype to determine the new system is technically feasible.
Economic Feasibility:
It helps to measure the cost-effectiveness of the project. Sometimes it can be called
cost-benefit analysis. After determining the user and requirements Mr. and Mrs. Khan can
working of economic feasibility of this project.
Organizational Feasibility:
It can measure the Mr. and Mrs. Khan has sufficient management expertise,
organizational capability to successfully implement the new system to increase the
productivity. This analysis can be done in the area. Resource sufficiency and management
prowess.
SDLC development methodology:
SDLC offers many models and methods agile methodology is most appropriate in this
organization.

4SYSTEMS ANALYSIS AND DESIGN
Agile methodology for information system development principles helps a small team
or an individual to develop a system. this methodology combines all process that can help a
developer, organization management and customers. The work process is divided into 2-4
weeks it is known as “sprints”. In this phase, a small team of developer looks after the
customer need and perform various testing. This methodology is best for this organization
because it is appropriate for a small company. in this organization speed and flexibility is
required that only agile can provide.
The benefit of agile methodology in an information system is, it can deal with the
rapid user requirement changes. With Frequent upgrades, an organization can implement a
new feature in this system.

5SYSTEMS ANALYSIS AND DESIGN
Part 2: Analysis Phase: -
List the functional and nonfunctional business requirements for the system:
Functional and nonfunctional requirements can determine the system and its
component and it provides the functions that a system can perform when a user uses the
system. This section of this report provides the functional and nonfunctional business
requirements.
Functional requirements:
Registration:
To use the system, a customer needs to log in first. They need to provide their email,
phone number and essential details for the login. due to this functionality, organization can
have every user detail.
Login:
after registration, a customer or admin can log into the system. This system consists of
two login option for customer can admin. After login, a customer and admin can perform
many tasks. With this functionality, an organization can track the user activity.
Search an order:
A customer can search for a specific product by providing the toy name.
Order online:
After selecting a product, a customer can order a product by providing their card
details and address. Multiple payment options are available in the system.
Receipt generator:

6SYSTEMS ANALYSIS AND DESIGN
After payment, a user can download the receipt, this system can also send the receipt
to every user email.
Nonfunctional requirements:
Accessibility:
This system is can accessible by any person. a disabled person or any child can order
a toy by using this system.
Integrability:
This system contains many subsystems. few subsystems are helpful to handle and
manage the workloads.
Extensibility:
This system is easily extensible. A software developer can easily add new feature
when required.
Portability:
This system can perform the same when a user uses it in their mobile phone or
desktops.

Data Storage Design:
There are two types of database storage formats are available. Database format and
file format. Files are mostly electronic lists of data that are developed for a specific
transaction. But a database is a huge collection of data. in the database, every data is logically
interconnected. A database management system a special type of software that can create the
populate the vast amount of data.

11SYSTEMS ANALYSIS AND DESIGN
A file data contains electronic lists of data. the example of news file format is CSV
file. In this project, Mr and Mrs. Khan using a CSV file for their old system.
There are many types of database such as relational, legacy, multidimensional and object can
be used here. The relational database is most appropriate here.
The relational database is the most popular database for this development process.
This is efficient and user friendly. This is the based-on collection of multiple tables. Every
table can have a primary key that can uniquely identify an object. Every table can be
connected with the help of foreign key in this data storage.
