A.

INTRODUCE

1.

Reasons for project formation
Nowadays, technological industry is the most important industry in developing
the economy of a country. The boom of 4.0 technological renovation becomes
a hot issue in adapting technology in different industries. For example,
adapting system of controlling coffee shop is now necessary requirement in
most of modern coffee shops.
At coffee shops, the increasing of the number of customers, workers as well as
many problems about materials will be solved quickly and efficiently if they
use technological improvement in their business. In addition, it also helps
businessman to save the time and their effort.

2.

Actual survey

2.1.

Current status survey
Hoai Niem Café is a modern coffee shop. The restaurant is located on 243 Man
Thien Street, District 9, Ho Chi Minh City.

 Advantages
With an area of 390 m2 of seating with many different spaces. The shop has
many green trees, airy, air-conditioned rooms, spacious seats. The shop has
staff wearing nice uniforms and delicious drinks especially caphuchino. Shop
opened from 7am to 10pm, the interior in the shop is young and modern.
Comfortable seats for xofa, have desks for 1 team.
 Disadvantages
It requires more workers, and the monitoring of business activities becomes
more complicated in coffee shops which do not use technology in running their
business, especially in controlling staff.
Practice teacher: Mr. Trinh Trong Tin

Finance activities are also complicated, such as: controlling bills, staff salary,
fee of materials, etc.
Searching, making statistical reports, updating information is waste of time and
inaccurate.
 Difficult problem
Currently, the cafe has not applied information technology in managing drinks
and payment bookings. Cafe staff also use manual methods such as taking
notes or using Excel to manage customers' drinks, registration and payment
bookings. Therefore, the following difficulties have been encountered:
-

The processing of booking drinks, registration and payment takes time

inflexibly.

-

Difficulty checking drinks, status of drinks

-

Difficulty in managing customer information, invoice information, room
registration information, registration for using cafe services, ...

Therefore, the cafe requires an application to manage the booking of drinks,
customer information, membership information, reports, service management
and payment, etc. for employees or guests. order drinks to solve the difficulties
and facilitate the cafe's business process to become quick and efficient.
