I would like to eat food from a variety of cuisines. The food
should be nutritious and freshly cooked.
I like when the food is hot and is served at the right time.
I don’t like to be kept waiting.
I am so swamped with work it is difficult for me to go to the
canteen and eat. I want options which I can eat at my
workstation while working.
I can take out a combined list of all the orders, which are sorted
out with sub totals of same dishes people have ordered. For eg
Fish and chips 10, Rice with kidney beans -10 etc.
The system should also give a floor wise list of orders to plan
deliveries.
Data and reports on most ordered items, least ordered items
with quantities for planning the inventory.
I should have a list with floor wise open orders.
After food is delivered, I will checkbox the items on my list.
After delivering all the orders I will close the orders on the
website.
A list of employees with total Price of food items ordered for the
specified period.
●
Employee wise list of items ordered and price (date wise) which
gets appended with salary statement for employees to check
deduction
●
Most ordered and least ordered items with various drilldowns
such as floor wise, department wise which can be used for
forecasting.
●
List of employees enrolled/ left and no of orders placed.
Problem Definition and Solution



1500 employee
12 floors
2 canteens





Preferred Lunchtime= 12pm–1pm(1Hour) Time Breakdown –
- 30min–35min– wasted in que/grab table
- 10min–15min– time spent eating
- 10min– reaching and coming back
Total number of employees – 1500
Total seating capacity=300
No of Turns required = 1500/300 = 5
Employee Complaint - Employees don’t always get the food they want.
Canteen problem – The canteen wastes a significant quantity of food by throwing away what is
not purchased.
Employee Request – To create an online system allowing the canteen user to order meals online,
to be delivered to their work location at a specified time and date.
Advantages and Objectives
Advantages of the Canteen Ordering System:




It would increase the chance of them getting the food items they prefer.
This would improve both their quality of work life and their productivity.
The food wastage will be reduced.
This will reduce the cost.
Objectives:




To design and develop a web application for rapid food ordering to be used by the canteen
customers.
To implement and test the web application for food ordering in a canteen.
To make it convenient for people who have limited time by giving them option to order food
online rapidly.
Reduced paper work.

Business Requirements:
Business objective – 1: Reduce canteen food wastage by a minimum of 30% within 6 months
following first release.
Scale: Value of food thrown away each month by examining the canteen inventory .


Previous - 25% wasted
Must plan for: Less than 15%
Business objective – 2: Reduce canteen operating costs by 15% within 12 months, following
initial release.
Business objective - 3: Increase average effective work time by 30 minutes per employee per
day, within 3 months.
Business objective - 4: By making the ordering process automated and by delivering the food
to the user's workstation, the canteen will be able to operate with lesser manpower.
Functional Requirements
1. The employee shall open the web page of the Canteen Ordering
System. He/she shall be presented with an up-to-date menu for the
day. It will have a list of all the dishes available in the canteen for the
day along with its prices.
2. The lunch order can be placed by employees latest by 11 am. After 11
am the system shall not allow the users to place orders for lunch
items so that the chefs have sufficient time to cook the ordered
dishes. There should be a Menu Manager (a canteen employee) who
shall create the menu and update the menu.
3. The users can select the lunch dishes they would like to eat and
create an order. They should be able to edit the items they want to
order anytime before checking out.
4. Once the order is confirmed and the user has checked out, they
should NOT be able to cancel or edit the order.
5. The canteen manager also known as order processor should be able
to view the orders placed by the employees. He shall take an
inventory of all the dishes ordered by different users and get them
cooked by the chef.
6. This canteen manager should be able to request a delivery to the
employees’ workstation.
7. There shall be a meal deliverer (delivery boy) who shall deliver the
lunch to the employee's desk. After delivering the lunch, this delivery
boy shall close the online customer order.
8. If a customer does not like any food item or is not happy with the
delivery system by the canteen, they should be able to submit
feedback.
9. There is no payment gateway for the same so the payment for dishes
ordered shall be deducted from employee’s salary. Hence, the
employees need to enroll for salary payment deduction. The payroll
system will handle payroll deductions.
10.
At the end of the month the payroll system shall calculate the
total number of dishes ordered by each employee. The payroll
system shall deduct money from the employee’s salary.
11.
Management would like the following reports:
 Which dishes are the most popular?
 How many employees are using the system?
 Satisfaction of the employees on using the system. This should
be tracked on the basis of feedback submitted by the
employees.
 Sales for each day
 Total monthly earnings
 Order forecasting i.e. a prediction of which items will be
ordered and when they will be ordered.

over a 40KBps modem connection.
PR-3: Responses to queries shall take no longer than 7 seconds to load onto the screen after the user

recover an incomplete order.
Platform independence-1: The system must run on different platforms and support different
database management systems.
Extensibility-1: The system must be easy to extend to provide new capabilities. 5.5 i18n The

be run.
System Requirement:
Scalability and performance: This canteen ordering system is required to support a volume of
1500 employees ordering. the web pages should be light and render fast.
Usability: The screens should be self-explanatory and very user friendly. Management would not
want employees not ordering from the system as they cannot understand the screens and data
fields on screen.
Environments: We are going to be creating and maintaining the program in Java. We chose Java
because it will not change much over time, and if we make it well, there will be very little
maintenance to be done on the code
