2SYSTEM ANALYSIS AND DESIGN
Business Outline:
Zedong is a Malaysia based T-Shirt selling organization. The organization is operating in
Malaysia for last ten years. Zedong has total fifteen offline retail shops throughout Malaysia.
Each retail store has a manager and several staff to manage daily processes. Zedong has
headquarter from where each store is managed. By the end of day, manager of each store fax
daily sales and attendance report to headquarter. Each store has a small scaled system that
connects accountant, manager and front desk computers. This in-house system uses Wi-Fi to
connect all the computers. The organization does not have any connection between the retail
outlets. Every outlet connects to each other through headquarter only. Current inventory
management approach is creating various issues. Lack of communication is making it hard for
management to control business of such a large scale. Often the data received from retail stores
does not match with the data stored in headquarter database. Zedong offers home delivery to
customers. Third party delivery services are hired to deliver product to customers given at the
time of placing orders. Home delivery happens when a specific product is unavailable. If the
customer pays in advance, when new stock arrives then organization sends preordered products
to customer through home delivery. Organization is having issues in increasing the business into
the areas that lies between two retail stores or cities near to a retail store.
Purpose of the System:
The primary objective of the system is to overcome geographical barrier. The system
should deliver a digital platform to the customer that can be accessed from remotely. The system
will be a web based system. This will increase customer reach. Another purpose of the system is
to connect all the retail stores with headquarter. All the retail stores can track each other’s

records and communicate with each other. As the system will use a centralized database, no
matter where data is updated, everyone can see that change. This will allow headquarter to
monitor sales activities throughout all the retail store in real time. Increasing brand value is
another purpose of the system. Currently, business of Zedong is popular among loyal customers
and recommendations from those customers. However, to increase business in untouched
regions, the organization must create good brand value. It will create a sense of loyalty between
new customers. One of the main purposes is assisting managers in decision making. System can
generate reports based on data stored in the database. These accurate and crucial information can
generate reports significant for decision making.
Business Opportunities:
The best opportunity is having new customers that can spread business of Zedong. New
customers will invite new buying patterns and new angles for business. Another business
opportunity is grasping better hold on to the market. The business will also make sure that all the
processes are done efficiently and effectively. Better communication between retail stores and
headquarter will create opportunities for saving internal processing cost and generate better
results in business management.
