CHAPTER 1 INTRODUCTION

1.1 Background of the Study

Metro Truck Builders Inc. in Dasmarias, Cavite and its other branches is

known to manufacturer different product for truck body building and assembling

for its customers of over 5,000 corporations in the country. Since the companys

warehouse holds large amount of inventory, and every week they need to find out

how many items or products were lessen from the products they have since the

first day of the week of transaction, it is more difficult for the employee involved

in keeping record to remember approximately inventory records and balances.

With the current situation at the companys warehouse, department uses

manual file system to manage about 250 items/products. When a new stock is

added or a new stock is deducted, records are modified with the use of pen and

paper, which we know can cause of inconsistency.

1.2 Statement of Objectives

Using pen and paper to record each transactions have been made has a

high chance of data inconsistency.

Misplaced records

Not enough security for the record items

Transactions are not quite slow and inaccurate in tracking the

records

1.2.1 General Objective

To design and develop an inventory management system for the

warehouse of Metro Truck Builders,Inc.

1.2.2 Specific Objective

To avoid losing of records

To provide data Security

To make transaction easy and accurate in tracking the

number of inventory

1.3 Significance of the Study

This study is made to make a computerized product inventory

management for the warehouse of Metro Truck Builders, Inc wherein

every week they will have a report on all about their products/items.

Since they have a large amount of inventory, it is necessary for them to

have a computerized system.

Using the system, the staffs who are in charge of the process can

easily determine products which are lessen on how many items are

purchased, subtracted and added for a week of transaction. Also, the

company will benefit a lot from the system since if they use the

proposed system, inventories will accurate. The contractors will be

easily notified of the items available and items which are not.

The study aims to develop an inventory management system which

can be very helpful for the company

1.4 Scope And Limitation

Scopes

It can do several functions like adding, search, deleting, modifying

or editing.

CHAPTER 2.0 Methodology of the Study

Prototyping is the process that enables the proponents to create a

model of the software to be built. A prototype is an original type, form, or

instance of something serving as a typical example, basis, or standard for

other things of the same category.

Figure 1.0 Prototyping Model

The Prototyping has the following phases:



6/21

PLANNING

In this phase, the proponents plan how to develop the development of the

inventory system gathers data needed for building the system. The proponents are

required to conduct series of interviews and research that are needed in the study.

Analysis

In the modeled the existing System and carefully analyzed the

Requirements needed to develop the system.

Designing

In the Designing phase, the proponents will construct and study the

design, structure and components of the system suitable for Metro Truck Builders,

Inc.

Implementation

The developer used Microsoft Visual Basic 6.0 by Microsoft Corporation

Ensure that the system will be compatible in all standard window based operating

System.

Maintenance

Tested the system by observing, operating and one-by-one testing, in this

Procedure, we can see the result much better and we could adjust errors if

Possible, also to ensure the user that the system is functional and well built.

CHAPTER 3.0 DATA GATHERING PROCEDURE AND OUTPUT

The interview is the primary technique for gathering information for the

development of the project. The proponents interviewed the person in charge for tracking

and keeping inventory records, and gathered all the necessary information that we needed

creating and developing our proposed system through interviews. The proponents asked

her several question with regards to their current system and what the problems are they

encountered. The proponents analyzed each statement that they gave for them to know

what would be the things they should consider in creating the system.

These are some of the question that we asked and their response.


How does your system? Semi Manual.

How long does your system work? Since from the start of this company.

How do you keep your records? Using a desktop pc.

Do you encounter problems on

keeping your records using your

current system?

Yes, frequently we do encounter that type

of problem.

Do you want to replace your old

system with a new one?

Definitely, we want a new system.

9/21

Physical Environment

The project will function in very computer that has adequate resources.

Microsoft Windows 2003 and later will be needed in order to function properly,

Must have at least 128mb of memory and 32-bit depth of screen resolution.

The system can only be used by the manager, secretary and the owner of

The Company.

Functionality

The system can do several functions like managing the orders, and

Managing the available stocks in the warehouse, the user should do some events

In order to process.

Resources

Any person will do maintenance as long as he knows the current flow of

The system and he knows working on computer software. The system will need a

Fully qualified computer operator in order to function very well and stable.

Security

The information of the system is restricted to people who are connected to

The company and the person to have a right to alter data entered on the database.
