INTRODUCTION
My project “Inventory Management System” is an online software application which fulfills the
requirement of a typical stock analysis in this company. It provides the interface to users in a
graphical way to manage the daily transactions as well as historical data. Also provides the
management repots like monthly inwards, monthly deliveries and monthly returns. In this
software they can add supplier, edit or delete supplier depends on their need. They can see and
keep track of their cost of different type of product.
For the user interface I use HTML, CSS, JavaScript and jQuery and for the backend I use PHP
programming language and the software used MySQL database for storing information and other
information’s. They can also generate weekly, monthly, yearly report based on their needs. This
will reduce the current manual paper work. This way the information will store in the central
database so anyone who has accessed to this system can access it. The inventory can be accessed
from anywhere with the help of internet. As there is an option for backup file so the company no
needs to worry about their data to loss.
BACKGROUND OF THE PROJECT
The current situation is that if my company buys something like computer, printer or other
materials for the organization a basic resource requirement list must be maintained manually by
the staff. To keep track of their inventory levels they must calculate a list of the product utilized
during a course of time, calculate and analyze the requirements for the future, and place their
next order to the vendors if needed. This process takes up a lot of time and human effort and is
also prone to human error. This is the current situation of the company facing regarding
inventory management system. It takes up a lot of time to manually keep track to sales and place
correct orders to vendors, wasting useful labor in trivial works. So, the company wants to build
their own inventory management system to solve the current problem they are facing. So, in this
project, a central system will be developed for the company by providing an efficient interface
for managing their inventory.

ii. No chance of losing information or data.

5. 5 | P a g e
iii. Inventory can be added and remove easily through the system.
iv. It reduces time and paper since all the data is recorded electronically in the system rather
than using files as a result searching information about a product becomes way too easy.
v. The inventory is always up to date in the system.
vi. Loss of inventory from the warehouse can be avoided.
vii. The inventory can be accessed from anywhere with the help of internet.
viii. Huge amount of data can be monitored in the system.
ix. Chances of error are reduced since the inventory list is not monitored by hand. This
ensures accuracy in the system.

uniform in their presentation, regardless of who has created them. This improves the
consistency in the system.
OBJECTIVE OF THE PROJECT
i. To keep inventory at sufficiently high level to perform production and sales activities
smoothly.
ii. To minimize investment in inventory at minimum level to maximize profitability.
iii. To ensure that the supply of raw material & finished goods will remain continuous so that
production process is not halted and demands of customers are duly met.
iv. To minimize carrying cost of inventory.
v. To keep investment in inventory at optimum level.
vi. To reduce the losses of theft, obsolescence & wastage etc.
vii. To make arrangement for sale of slow moving items.
viii. To produce simple not complexity system.
ix. To create a backup of files in every successful operation.
x. To spend less time in searching and retrieving of information.
xi. To maintain the complete inventory records of stock, receipt, details of purchasers and
sellers for a department store.

PRODUCT DESCRIPTION
Effective inventory management is all about knowing what is on hand, where it is in use, and
how much finished product results. Inventory management is the process of efficiently
overseeing the constant flow of units into and out of an existing inventory. This process usually
involves controlling the transfer in of units in order to prevent the inventory from becoming too
high or dwindling to levels that could put the operation of the company into jeopardy. Its three
main areas of concern are:
Acquisition:
Acquisition procedures are established to assist personnel in procurement of software and
hardware products. Its main purpose is to ensure that proper justifications are performed and that
financial guidelines are followed.
Redeployment:
Redeployment procedures are responsible for ensuring that assets are tracked when moved from
one location to another and that budgetary considerations are adjusted as needed. Should a
product be moved in conjunction with its original owner then the Inventory System is updated
to reflect the new location. Should a product location and owner change, then the Inventory
System must be updated to reflect the new owner and their location. In this case, the old product
is deleted from the original owner's budget and added to the new owner's budget.

8. 8 | P a g e
Termination:
Termination is responsible for deleting the asset from the inventory when it is discontinued or
replaced. The owner's budget will be updated to reflect the asset termination and the asset will no
longer be listed when location reports are generated.
The project is about developing such online based inventory management system that will have
an inventory database by which, the company can control the inventories of all the warehouses
and all the dealers will be allowed to know about the inventories of other dealers through the
database and can place orders and complete purchasing among them using the database. The
focus of the project is to reduce the time for ordering products which are consumed in bulk, and
a dealer tries to find product by calling the other dealers one by one. That is another aim is also
to eliminate the chance of having wrong products in the order line of which there are chances of
happening when the orders are getting placed through the phone. Also, the project is to optimize
the documentation processes of the product, to organize the products in the warehouse more
thoroughly, to control the products storage, transfers, and purchases more easily. The two
primary deliverables are the web site and the database.

INFORMATION GAHERING METHOD
Joint Application Design (JAD): This process includes approach for enhancing user
participation, expediting development and improving the quality of specifications. It can replace
a series of interviews with the user community. In a group setting the analyst can accomplish
requirement analysis and design the user interface.
In my Online Inventory Management System, I have used JAD to gather system requirement
from Owner and the Supplier. I managed to set up a two-day discussion session at a Resort with
the owner and few suppliers. I at first made sure that they are comfortable and then discussed
thoroughly. It was a kind of focus group discussion It was easy for me as an analyst to hear their
requirement and at a time getting feedback for the system. It was time efficient as well.
Questionnaire: This process is useful in gathering information from the users of the system.
This reduces time as we do not have to interview large number of people one by one.
I have used a combination of multiple choice questions, yes/no questions and ranking range
questions to collect information. I have used this technique so that I can get proper feedback on
those things which require change so that these changes can make my system more responsive.
Observation: This process gives a total overview of how the system of the organization is
working. Analyst needs to get involve at every site of the system to do proper observation.
I have conduct meetings, sessions with the owner and supplier. Ask questionnaire to the users.
Conduct a bit sampling and finally make a prototype of the system. By means of observation on
those events I could manage to get a holistic idea of the system which helped me to give some
end touch of my work.
