PREFACE
ach and every system either manual or computerized is a
collection of many sub systems. Similarly the system at
PIONEER PAKISTAN SEED LTD. have many sub systems
such as Payroll for their employees, Inventory Control for
their stock keeping, Accounts Maintenance for transaction occurs
in daily office workings. We choose Inventory Control at
PIONEER PAKISTAN SEED LTD. because they have very large
warehouses for storage of different types of items, their respected
hybrids in different sizes of bags.
So this thesis is about inventory control system of PIONEER
PAKISTAN SEED LIMITED, which consists of nine chapters.
First chapter contains information about the organization
and the main objectives of the organization and also an
organizational structure.
The second chapter provides information about inventory and
its types.
The third chapter is about the existing system of the
organization, which is manual system.
The fourth chapter is about the proposed system for the
PIONEER PAKISTAN SEED LIMITED.
The fifth chapter is about the system designing. It describes
all the table layouts and their fields with their types.
In the sixth chapter we select a language for the
development of the software.
In the seventh chapter information about software
implementation is given.
In chapter eight, all the input/output data screens and source
codes are presents.
The last chapter is a user’s guide, which gives view of the
procedures for the users to operate and handle the control of the
new system.
In epilogue we realizes our limitations in imaginations about
creativity, development of project and analyzing the system.

1.3 PROJECT OVERVIEW
The inventory of PIONEER PAKISTAN SEED LTD. is of two
types:
a) Commercial seed.
b) Local production.
1.3.1 COMMERCIAL SEED
According to the requirement of the growers or market an order is
sent to USA from which demanded seed is arrived and stocked in the
warehouses of the company. After that according to the demand of the
growers or the market the imported seed is distributed.
1.3.2 LOCAL PRODUCTION
In local production first of all contract is made with the growers,
then parent seed and chemicals are provided to the growers. When crop
is grown then detesling is made. Detesling is a process of preparing

5
hybrid seeds. Then ripped crop is brought to the seed plant for
processing. In processing there are many process involves such as
weaghtage, unload, sorting, drying, shelling, cleaning, sizing, gravity
treatment like insecticides, fungicides, coloring, or dying, after it
bagging and then store the finished seeds in cold storage or local
warehouse for further use. When finished seed is prepared then packing
is made in the plant with the help of automatic machines. This stock is
then distributed among growers or in the market.

2.1 WHAT IS INVENTORY
An inventory is an idle resource that process economic value.
Broadly defined, inventories are useable resources that are at a given
point in time. In a manufacturing environment this would include raw
materials, semi finished goods (work in process) and finished goods. In
retail firms, inventory is generally viewed as the stock of the goods for
sale. Inventories however may include nonphysical assets such as cash,
accounts receivable and personal. Although we usually think of
inventories in the context of manufacturing and distribution firms, other
types of business have inventory. Banks, for example, must maintain an
inventory of cash to meet customer demand. Non business organizations
have inventory too. Hospitals have inventories of medicine, surgical
supplies etc. The particular inventories that must be managed depend
upon the nature of the nature of the business, but the following inventory
types are generally found in all business.
2.2 RAW MATERIAL
Raw materials are the ingredients that go in to the final product.
Raw materials are the paper ink and binding to make books. The exact
form of the material depends upon the manufacturing process. Some
manufacturers take nature’s own resources and convert them into a
product. Steel-making firms must have iron and coal to produce steel.
The steel then sold to auto manufacturers, and for them it becomes a raw
material. Other manufacturers assemble component parts into a final
product. Their raw materials inventory consists of many different
components supplied by other manufacturers.

9
2.3 SUPPLIES
Every business requires materials that do not become part of the
final product. These items are term as MRO items (maintain, repair, and
operating supplies) are usually small in number and expanse compared
to other inventories. Nevertheless, they are essential to the operation of
the plant.
2.4 WORK IN PROCESS
Raw materials moving through the stages of production are called
work in process. Depending on the length and complexity of the
production process, work in process inventory can be relatively large
and small.
2.5 FINISHED GOODS
Finished goods consist of unsold final products. Finished goods
are stored at the manufacturing facility itself or at some point in the
distribution channel at warehouse or retails.
2.6 PURPOSES OF INVENTORIES
Inventories serve a multitude of purposes, including the following:
1. They aid continues production by ensuring that inputs are always
available and that economic production runs can be made.

10
2. They faceplate intermittent production of several production on the
same facilities (even though demand may be relatively constant for
each product).
3. They decouple successive stages in processing a product so that
downtime in one stage does not stop the entire process.
4. They help level production activities, stabilize employment and
improve labor relations by storing human and machine effort.
5. They provide a mean of hedging against future price and delivery
uncertainties, such as strikes, price increases and inflation.
6. They provide a means of obtaining and handling materials
uneconomic lot sizes and gaining quantity discounts.
7. They help service customer with varying demands and in various
locations because an adequate supply is maintained to meet their
immediate and seasonal needs.
2.7 COSTING MATERIALS ISSUES
Of the various methods in use for the costing of materials issues or
sailing or purchasing of inventories a rough division can be made
between those, which use so-called actual costs, and those, which use
standard costs:
1. Specific Cost:
Under this method specific cost of the units of materials issued is
charged to production. It can be used efficiently in those concerns
where it is possible to keep each lot of material purchased separate
from other lots of the same material in the storeroom and different
stores ledger card is used for each lot purchased. In such
circumstances at the time of materiel issue, it will be possible to find
out the particular purchased and cost represented by the material
issued.

11
2. First-in, First-Out:
It is also called FIFO method. The working of this method is based
upon the assumption that the various lots of materials purchased are
used in the same order in which they were received. Further,
materials from each lot are charged out at the price of their original
purchase. Owing to this the method is sometimes called ‘original
price method’.
3. Last-in, Last-Out:
It is also called LIFO method. Under this method the materials
issued take the cost of the last units received. This method is
predicted upon the idea that materials to be charged to production
should carry the most recently purchased price of materials of that
kind. The requisitions are priced by working back from the most
recent lot of materials received. In other words, the cost of most
recent lot of materials purchased is applied to price requisitions until
that lot is exhausted then the next recent lot’s price is used to price
requisitions, and so on through successive consignments. This result
in leaving the old items of materials in inventory.
4. Weighted Average:
This method of costing materials issues is based upon the
assumptions that materials issues from stock are composed of
uniform quantities taken from each lot in stock at the date of issue.
In this method average cost of materials purchased is charged to
production rather than actual cost. In other words, it is assumed that
where a material is purchased at different prices the cost of a unit of
such material will be the average of the cost of all units purchased
during a particular period.
The costing method used in PIONEER PAKISTAN SEED LTD.
for sailing or purchasing of inventories is FIFO (first in first out)
method.

3.1 INTRODUCTION
It is very important for the system designer to understand the
system before its improvements and implementation. The system
designer must know what is going on.
After conducting the comprehensive study of the existing system,
which is running manually, it is viewed that the management has some
problems for the producer of adding and retrieving information about the
items, which are purchased, issued to any distributors or others. The
existing system is running manually as followed:
3.2 STOCK REGISTER
Management of PIONEER PAKISTAN SEED LTD. has one stock
register. An index is maintained in the beginning of the register. All
entries about all items are made in stock register. Local production as
well as commercial seed’s information is entered in the stock register.
The stock register of PIONEER PAKISTAN SEED LTD. has following
information.
s Date
s Name of Article
s Particulars
s Gate Pass No.
s Received Quantity
s Issued Quantity
s Balance in K.G.
s Document

14
3.3 PARENT SEED, CHEMICAL AND
PACKING MATERIAL REGISTER
When company contracts with the grower then it supplies parent
seed and chemicals to growers. And after processing is completed then
packing is made. The information about raw material is entered in this
register, which has following information:
s Date
s Particulars
s Gate Pass No.
s Received Quantity
s Issued Quantity
s Balance in Stock
s Document
3.4 RAW MATERIAL REGISTER
When production is made locally, it is called local production. For
this Raw material is purchased from the grower. All information about
raw material is recorded in this register that has following information:
s Sr. No.
s Date
s Grower
s I.G.P.

15
s Truck No.
s No. Of bags.
s Gross weight
s Truck weight
s Bags weight
s Net weight
s Moisture
s Hybrid
s Bin no.
3.5 DOCUMENTS
There are different types of documents involved in office at
PIONEER PAKISTAN SEED LTD. for any transaction or input/output
of material to any party or from anywhere. These documents are
mentioned as under:
s O.G.P. (Outward Gate Pass)
s I.G.P. (Inward Gate Pass)
s S.I.T. (Stock Inter Transfer)
s D.N. (delivery Note)
s S.S.T. (Seed Sample Trial)
s D.C. (Delivery Challan)
s G.R.N. (Goods Receiving Net)

16
3.6 LIMITATIONS IN EXISTING SYSTEM
After studying the existing system that is currently functioning
manually. Many drawbacks have found. Some of the major limitations
are listed below:
s The first and most vital fault in their system is they done all work
manually, which make their whole system slow and inefficient.
s Due to manual system there is no proper maintaining of records and
order specifications if need in sometime future.
s A lot of space is consumed to maintain the record of every
transaction occur in the office of the PIONEER PAKISTAN SEED
LTD. such as arrival of raw material trucks, or stock of finished
seeds in the warehouses, or the sail of finished seeds to any
customer.
s It was very laborious job to make any report about daily
production, weekly or monthly production or profit or loss at the
end of the year or to know how much unfinished seed in the
processing BINS.
s If the Management of the PIONEER PAKISTAN SEED LTD.
wants to know about the sales information at any particular date
then there is a lot of time was consumed to prepare the desire
report. Similar case with the Grower name and corresponding lot
no. assign to him.
And also much other limitation is observed and feels in the current
system that is very time consuming system.

4.1 INTRODUCTION
The proposed system will be a computer-based system. All the
input data will be properly organized and stored and will be processed
for required output to provide timely information. Proposed system will
perform all the activities described in the existing system and will
provide necessary information with accuracy and efficiently. Proposed
system is designed keeping in mind all the problems being faced in the
present manual system.
The scope of this system is to provide an automated flexible
computerized inventory control system. The system will provide on-line
information and will be capable of generating necessary reports. The
scope of this system is to provide up to date, consistent and reliable
information.
4.2 NEED FOR COMPUTERIZED PROCESSING
The PIONEER PAKISTAN SEED LTD. has increased its business
day by day. With the passage of time handling this large scale
production and inventory control becomes increasingly difficult. To
overcome these problems a computer-based system is needed.
Computerization means the automation of a system, which was
previously working manually and was slow. After computerization its
becomes more sufficient and accurate.
Computerization is a very sophisticated and technical job and is to
be required a comprehensive study of the system. So that the system
analyst can understand the whole system, its weakness and drawbacks.
Computer information provided by a customer is highly reliable and
accurate. Further it provides information with in seconds.

19
That is why commercial and scientific organization are switching
over to computer based information system.
4.3 SOFTWARE PROCESS MODELS
To develop software for any purpose we must follow some rules
and strategies to solve the actual problem. A software process model
provides these strategies and rules. If we see in the field of software
engineering there are many process models for different types of
problems to solve. Some of them are listed below:
1. The Linear Sequential Model:
This process model is also called “classic life cycle” or the “waterfall
model”, the linear sequential model suggests a systematic, sequential
approach to software development that begins at the system level and
progresses through analysis, design, coding, testing and maintenance.
2. The Prototyping Model:
This model begins with requirements gathering. Developer and user
meet and define the overall objectives for the software, identify
whatever requirements are known, and outline areas where definition
is mandatory. A “quick design” then occurs. The quick design leads
to the construction of a Prototype.
3. The RAD Model:
Rapid Application development is a linear sequential software
development process model that emphasizes an extremely short
development cycle. The RAD model is a “high-speed” adaptation of
the linear sequential model in which rapid development is achieved
by using a component-based construction approach. Use primarily for
information system applications.

20
There are also some Evolutionary Software Process Models which
includes The Incremental Model, The Spiral Model, The Component
Assembly Model, The Concurrent Development Model, The Formal
Methods Model and Fourth generation Techniques. A number of
different Process Models for software development have been proposed,
each exhibiting strengths and weaknesses, but all having a series of
generic phases in common.
4.4 PHASES OF PROPOSED SYSTEM
We choose linear sequential model for our software development
because of this is neat, concise series of obvious steps, systematic
sequential approach to software development. This model is consists on
following phases:
s Preliminary Investigation
s Analysis
s Design
s Development
s Implementation
4.4.1 PRELIMINARY INVESTIGATION
This phase deals with the determination of problems. So going
through this phase three simple questions were asked from officers.

21
1. The Impetus For Chance:
In this step reasons are studies for which new system is needed or old
system is being revised.
2. True Nature Of the Problem:
In this step symptoms and the actual problems are differentiated. This
will help us to identify the problem.
3. Scope Of The Problem:
In this step the specific areas in which the problem lies, is defined.
4.4.2 ANALYSIS PHASE
The analysis phase is primarily concerned with studying the
existing system. After analysis the existing system we can then design
and implement a better and user-friendly computerized system.
1. Understanding The System:
In this step, the system before doing sometimes is understood to
improve its functioning. In other words, we must find out what is
going on.
2. User Involvement:
The most successful projects or systems are in which user plays an
active and vital role. The user’s knowledge of the system is needed
for a new and a better system.
3. Data Gathering:
The basic work in analysis phase is gathering and analyzing the data.
Two common data gathering techniques are interviews and

22
questioners. The analyst also wants to collect the data about existing
system.
4. Data Analysis:
The collect data serve as foundation for the documentation of system
analysis phase.
5. System Requirement:
The purpose of gathering and analyzing the data is to establish the
system requirements because the design of the new system will be
based on these system requirements.
4.4.3 DESIGN PHASE
Design phase is the most important phase in the system. This
phase is the most time consuming part of the project. The design phase
comes after the comprehensive study of the existing system. If the
analyst will not spend adequate time in designing, he will not be able to
fulfill the requirements of the users.
The design phase mostly consists of the following steps:
1. Preliminary Design:
It is particularly important first to design how the system will look
and respond to user before designing the software structure.
The most critical and creative aspect of development is design the
user interface design determines how the system will look for the
user from outside while the preliminary design of software structure
determines how the system will provide the desired function to the
users.

23
2. Detail Design:
In the detail design the actual contents of each module in the
preliminary design are planned. Designing each module is much like
writing a short program. Here is a partial list of those design
activities, which are used in design phase.
s Design of Input
s Design of Output
s Design system flow chart
This list is not a comprehensive and not all lists will be used for
all systems. This large and detail document, usually referred to as the
detail design specification, will be an outgrowth of the preliminary
design document.
A very important issue in building software is deciding what
programming language will be used. Often the very success or failure
of the system can depend on the choice of language.
4.4.4 DEVELOPMENT PHASE
Development of the proposed system is conducted as:
s Development of the computer programs, i.e. Coding
s Testing of the computer programs with dummy date
s Testing of computer programs with real data.
4.4.5 IMPLEMENTATION PHASE
Implementation is the process of replacing the old system with the
new one. The key point in implementation is that users are now going to
switch to the new system.

24
For smooth transition, groundwork must be laid carefully. Criteria
must be evaluated to establish that the system is actually ready to be
converted.
Conversion to the system must be planned carefully. Data files
must be prepared to be used by the new system. Personnel who will use
or interact with the system must be trained. All conversion related
activities must be a trying one for those involved.
When the new system has been converted, some neutral party
usually evaluates it. The evaluator is probably another analyst, either
from the organization or from an independent firm.
4.5 OBJECTIVES OF THE PROPOSED SYSTEM
The most important factor in developing a computerized system
for the user is that it should meet as closely as possible the objectives
defined by the user along with the system analyst. The analyst is the
person who is capable and fully aware of the computer technology and
the user has the knowledge of the organization in which he is working.
Both persons with their knowledge and CO-operation define the
objectives of the proposed system. These objectives must be able to
satisfy the requirements of the users. In addition, the relative importance
of each objective should be established.
Keeping in mind the drawbacks of the existing system, the
following are the major objectives, which have been chosen before
designing the proposed system.
1. EFFICIENCY:
Efficiency is the degree to which we minimize utilization of
resources for achieving an object. The proposed system is faster
and efficient than the existing manual system.

25
2. USER FRIENDLY:
Authorized staff should communicate with the system through
simple conversions. No specialized computer staff must be
required. This makes the system user friendly.
3. TIME FACTOR:
Time is an important factor for decision-making. The higher
authorities require quick response to their queries because decisions
are based on up to date information. The required reports can be
produced quickly.
4. DATA SECURITY:
It refers to protection from any accidental loss or destruction of
data. The data required for decision-making is very important,
sensitive and valuable. Therefor reliability of the system may be
secured by giving a regular and guaranteed service to the user i.e. a
password is given to the user and by using that password he can
initialize the files.
5. ACCEPTABILITY:
The system should be acceptable to the organization. It should
satisfy the previous and new objectives in a better way.
6. ECONOMY:
The proposed system should be cost beneficial as compared to the
existing system.
7. PRODUCTIVITY:
A significant reduction in clerical staff will lead to improve staff
productivity.
8. ACCURACY:
The proposed system will provide accurate information, needed for
decision-making and error free results. It will ensure efficient and
accurate record keeping.

26
9. RELIABILITY:
The new system is more reliable than the manual one due to its
accuracy and security. So that timely decision-making may be
possible.
10. PERFORMANCE:
The proposed system should reduce the time and efforts required
retrieving information.
11. USABILITY:
The goal of the proposed system is to keeping every thing nice and
simple for all users. Since the users of the proposed system will be
the staff of the finance and account’s system section so that
application should be as self documented as possible, and the user
should not need to memories lot to use it comfortably.
12. COMPREHENSIVE DATA BASE:
The proposed system has comprehensive database in which
insertion, deletion, modification, retrieval about records and
facilities of various reports are available.
13. MINIMIZE THE REDUNDANCY:
The proposed system has no redundancy. This means that the files
are designed in such a way that minimum data is duplicated in the
files.
14. EASE OF OPERATION:
Graphical user interface (GUI) and menu driven facility is provided
in the system. The use of various hot keys and use of mouse or any
pointing device makes very easier for user to operate the system
without any complications. Screens guide the operator through the
system to perform the required task.
15. MAINTAINABILITY:
The system should be easily modified and expanded to meet future
user needs.

27
16. ROBUSTNESS:
The proposed system should be correctly and sensibly handles all
exceptional data
4.6 PROPOSED SYSTEM REQUIREMENTS
The main objectives of the proposed computerized information
system are to make an automated new computerized system that will
solve the aforesaid problems. The system will enable the PIONEER
ADMINISTRATION to control and manage the inventory information
in an ordered and better way.
Change of the existing system to a new system whether manual or
computerized, needs some requirements on which new system will be
based. As the requirements are the base for the new system, therefore
these should be clear and well defined. For this requirement analysis,
system study is very much essential and user is main factor in fixing
system requirements.
In our system, after studying the existing manual system. Defining
the problems, specifying system scope and objectives, analyzing
gathered data and discussing various problems relating to inventory
control system, production officer, store incharg and other staff, system
requirements were identified and analyzed. The requirements of our
system are:
s It must provide some on-line information, as soft copy reports on
the monitor screen
s Generate some printed reports as hard copy on paper
The system is required to provide the output in the form of reports

28
4.6.1 REPORTS
1. Lot wise report about raw material to finished seed and stock
material.
2. Bags size wise report of the finished seeds in the warehouse.
3. Hybrid wise report of the finished seeds in the warehouse.
4. Year wise report of the sale of the finished seeds
5. Monthly report of the stock.
4.6.2 INPUT SCREENS
The screens for the data entry will be similar to that of their paper
formats of “INVENTORY CONTROL SYSTEM”.
4.6.3 HUMAN INTERFACE
The proposed system of “INVENTORY CONTROL SYSTEM”
will have a very user-friendly graphical user interface. It will menu
driven by messages help at different levels and various push buttons on
the forms which can be easily driven by clicking mouse or any other
pointing device also many hot keys makes much easier for the user to
operate the system.

5.1 INTRODUCTION
System design is the most important of all the phase in the system
life cycle. After studying the existing system, analyst should plan and
design new system that meets the needs of the users. System design
presents specific information for the designing of the output, input,
processing, life structure and database.
Economy, reliability, responsiveness and modularity should be
considered in design. This chapter deals with designing of the system,
which comprises of designing output forms, input forms, codes and files.
5.2 DESIGN APPROACHES
Design methods, strategies and methodologies are tools for the
designer. Since designing a new system is a creative function land as
such very difficult to define and describe in a detail. It follows that a
good designer may employee a design standard but will constantly be
reviewing its effectiveness and looking for improvements. The common
design methods are:
a) TOP-DOWN DESIGN
b) BOTTOM-UP DESIGN
c) CRITICAL-FIRST DESIGN
d) STRUCTURED DESIGN

31
5.2.1 TOP-DOWN DESIGN
Top-down design is based around the idea that there are various
levels of decision, which need to be made, varying from those
concerning the goals of project and the system boundary down to detail
level of allocating data to disks and layout of printed reports.
Progressively analyzing higher-level function into more detail is refereed
to as functional decomposition; stepwise refinement refers to gradually
increase the precision of a statement. These may both be considered as
specific varieties of top-down development method.
5.2.2 BOTTOM-UP DESIGN
Bottom-up design starts with basics units of the system, and from
these the design builds up to higher level. A system created in this way
could start with the design of input document and output outs, eventually
arriving at the point where a management information system has been
built.
This method has a longer history than the others and some author
claim it has better success rate than top-down design. Bottom-up design
also tends to produce system with complex interfaces between modules
because were not designed to be interfaced in the first phase.
5.2.3 CRITICAL-FIRST DESIGN
Critical-first design is a method system design that emphasizes the
identification of the most critical components in the system. If the
potential problem areas can be identified at an early stage it is possible to
try to solve these before going onto further design work. It is very
difficult to know for certain at the beginning of the project what

32
constitutes the biggest potential problem but tackling the most critical
components first is a very practical way of commencing system design.
This method could be used to design a whole system by making all parts
of design in terms of difficulty and working down the list, although this
is not frequently done.
5.2.4 STRUCTURED DESIGN
This designing approach is similar to Top-Down Approach. This
approach provides a variety of new documentation techniques, but also
bring the project emphases upon logical design prior to physical
implementation considerations. This follows on from the freedom from
hardware constraints, which means that designers can now decide what
is wanted prior to looking at how this will be achieved.
5.3 ADOPTED APPROACH
Since structured approach or structured methodology is viewed as
top-down approach in addition to new documentation techniques, we
select this approach for designing new system.
The structured methodology is based on building a logical model
of the system, i.e. identifying the major components of the system,
decomposing them into their lower level components and iterating until
the desired level of data is achieved.
Top-down design methods after result in stepwise refinement.
Starting from abstract design, in each step the design is refined to a
more concrete level, until we reach a level where no more refinement is
needed and the design can be implemented directly. Pure top-down or
bottom-up approaches are often not practical. For bottom-up approaches
to be successful. We must have a good notion of the top and in top-

33
down approach one must have some idea about the feasibility of the
components specified during design.
5.4 STRUCTURED TOOLS
Structured design approach is realized through its rich set of
analysis and design tools, each of which serves a particular purpose in
developing the specification, like:
5.4.1 DATA FLOW DIAGRAMS
Data flow diagram represents a significant change from which in
the typical way, system is viewed. The use of DFDs provided a
complete, clean and global understanding of the system than did in the
traditional approach. These diagrams illustrate the flow of data through
a system and the work or processing performed by that system. There
are only four symbols that can appear on a DFD: the Process, the
internal or external Entity, the Data Store and the Data Flow. With these
symbols we can model processing for any system.
These are of three types:
1. Context DFD:
Here, the emphasis is on the relationship between the system and
its environment. No information about the structure of the system
itself is pictured in a context DFD.
2. Diagram 0:
A Diagram 0 (diagram zero) shows the system itself. It pictures
the major processes along with the external entities, data stores, and
data flow

34
3. Detailed DFD:
These are explosions of higher-level representations and are
detailed pictures of major processes or subsystems. They are likely
to be used by designers in their own work rather than for
presentations to users or managers.
5.4.2 DATA DICTIONARY
A data dictionary is a repository of information that describes the
logical structure of database. It has entries for record types, data item
types, and data aggregates, along with other information. The data
dictionary contains metedata, data about the data in the database.
5.5 DESIGN SPECIFICATION
System designing consists of the following three steps:
a) Output Designing.
b) Input Designing.
c) File Designing.
5.5.1 OUTPUT DESIGNING
Output designing from the system can be in the form of queries
and reports.
Some features are to be considered while designing output like:

35
s What output information do users need?
s What format and volume it should have?
s Output should be good looking.
s They should be easy to understand.
s Unnecessary information should be avoided.
The new output reports of Automated Inventory Control System
are like:
s Lot wise report about raw material to finished seed and stock
material.
s Bags size wise report of the finished seeds in the warehouse.
s Hybrid wise report of the finished seeds in the warehouse.
s Year wise report of the sale of the finished seeds
s Monthly report of the stock.
5.5.2 INPUT DESIGNING
Designing of input mainly involves the form designing. Since
input always plays very important role in data entry phase, so these
forms have been very carefully and precisely designed. These are
s Finished seeds form
s Unfinished seeds form
s Item form
s Warehouse form
s Warehouse item form
s Bag size form

36
5.5.3 FILE DESIGNING
File designing is of fundamental significance in any efficient
computerized system. Files are designed such that queries and reports
are produced in least amount of time:
There are two steps involve while designing the files:
1. First Step:
In the files we have designed is the selection of candidate key,
which UNIQUELY identifies the records in the data structure.
2. Second Step:
Normalization is done in the second step of design. Normalization
techniques are used to avoid data redundancy and inconsistency in the
files. It is the method of proving that what we have done would have
been correct, i.e. there is no duplication of any record in the files.
5.6 DESCRIPTION OF FILES
As a result of above-mentioned procedure the proposed system
uses number of databases files. Database is a collection of related data
about an enterprise with multiple uses. A brief description of the files
designed for the proposed system is as follows:

6.1 INTRODUCTION
The conversion of manual processing into computerized processing
requires the development of computer programs for the proposed system.
Software development is an important phase. Special care is to be taken
because it may cause heavy loss even a situation may arise that
redevelopment of the whole system, because it involves the realization
of the whole system. Computer programs are written and arrangements
are made to train the personnel.
6.2 WHY COMPUTER BASED SYSTEM
Many systems are being computerized now days. The reason for
computerization is that the work is done very quickly and accurately.
The results produced by computer are in a micro or in a nano seconds.
So, efficiency and accuracy are the main reasons, for which, computer is
considered to be one of those fields in which extensive research is being
done today. For this reason, PIONEER PAKISTAN SEED LTD. wants
to computerize INVENTORY CONTROL SYSTEM, so that information
may be retrieved and manipulated, whenever required, quickly and
easily.
6.3 SELECTION OF LANGUAGE
The main purpose of this phase is to develop the software that
gives requirements of the users. A database can solve all the problems of
new proposed system so that a database is a collection of files linked
with each other with some common link fields. The link fields then
manipulate the files, which includes retrieval, deletion, addition and

46
updating of the record. This system can be employed for entering data,
retrieving of this data and updating a part of data.
There are many languages that are used to solve the problems of
users. Each language has its own nature and different applications. So
the selection of the language is very important for the development of
the software. Also the language depends upon hardware used. Keeping
in mind all these things, the choice of programming language is
important and definitely depends upon the problem on hand. As the new
proposed system require the handling of data files and indexed files
there are following languages that may be suitable for INVENTORY
CONTROL SYSTEM.
The languages are given:
1. COBOL
2. Clipper
3. Delphi
4. Informics
5. Oracle
6. Visual Basic
7. Visual FoxPro
We have selected Visual Basic for the development of the new
proposed system because:
1. Its processing is very fast.
2. It is more efficient than other languages.
3. Visual Basic has its own database.
4. It provides the facility of form designing and then linking with the
database.

47
5. The more constructs are available in Visual Basic.
The software developed in Visual Basic can be easily extended by
the end-user to fit his future needs. For example, Visual Basic allows
extensibility in two ways:
s It allows the use of ActiveX controls, Allowing for the addition of
functionality that the original designers did not include in the
program.
s Visual Basic has an extensibility model that allows for the creation
of Add-ins and Wizards to perform tasks on code and forms. This
allows developers to use the program to create helper programs for
themselves and prototypes for others.
6.4 SOFTWARE DEVELOPMENT
The salient feature in the development of an efficient computerized
system is software development. The purpose of software development
is to transfer the complete proposed system into the executable computer
programs.
Programming is not simply science but there is a touch of art
involved in it. There is however a number of clearly identifiable steps
that are always involved in the programming phase and those provide a
convenient framework.
These steps are:
1. Define the problem.
2. Plane a solution.
3. Maintain the program.

48
Thus the purpose of the programming task is to code, debug and
test each program before and after integrating them into the modules.
6.5 METHODS OF DEVELOPMENT PHASE
The development phase of the proposed system includes the
following methods:
s Coding.
s Compilation of program.
s Testing of program.
6.5.1 CODING
Data coding is common practice. There are many ways to plan a
code. Subject is very tedious and quite complex. The group
classification codes have been used for the system, because codes can
be easily generated by these methods.
6.5.2 COMPILING
When all the coding of programs has been completed, then the
programs are compiled using the available compiler by the system on
which the development has been done.

49
6.5.3 TESTING
Even if the system is developed using correct algorithms, its
reliability remains doubtful. The validation of the result is very
important to make the system acceptable. Before making the system
operational, it is necessary to check that the new system is
comprehensive with in its limits and produced output result accurately.
Programs and subroutines were confirmed for the desired results.
Major consideration was laid on procedures. All subprograms were
tested and combined results were compared with the manual results. All
possible efforts were made to make sure that system produced selectable
results under any condition.
During this process all programming bugs and minor design faults
were removed. Necessary changes were made in design and structure;
special care was taken not to change the actual logic of the system.
The basic concept of testing the system is to confirm that the
developed system fulfills all the objectives and requirements of the
management and proposed system provide accurate information. Before
the implementation of the system, using the following methods first
tests the system:
1. Unit Testing:
Testing the single module or program to check that all programs are
running well.
2. System Testing:
Testing of the system linking all the files and environment data to
check that all the programs are working correctly.
3. Volume Testing:
Testing the system using the large number of data to check the
efficiency of the system required by the organization.

50
6.6 SYSTEM EVALUATION
The new system should be evaluated to determine whether the
stated objectives were met. The evaluation is necessary to keep the
system updated of business and economic environment, as well as
technological changes in the electronic data processing. System
evaluation is also important because it judges the compatibility of
developed system with the existing system and checks the validity
under organizational constraints. Generally, a system, which produced
information that, possess the properties of accuracy, timeliness,
completeness is declared to successful.
However comparison are often made in one or more of these
properties for economic reasons. The user of the new system is in the
best position to determine, on an ongoing basis, the effectiveness of the
system. The system developed for PIONEER PAKISTAN SEED LTD.
is directed to meet their problems.
Accuracy is the ratio of correct information to the total volume of
information produced over a period. The accuracy level depends on the
type of information produced. Validation checks have been made to
ensure the accuracy of the system.
6.6.1 TIMELINESS
It is another important characteristic of the new system. This was
the major problem faced by management of INVENTORY CONTROL
SYSTEM. If some body needs some information, he had to wait for few
days with the result that by the time the information might not be of any
value. New system provides accurate and instantaneous response to its
users.

51
6.6.2 CONCISENESS
Concise information that summarizes the relevant data and point
out the area of exception to the normal and planed activities is what the
management and the user need.
6.6.3 EFFICIENCY
The new system is thus efficient as it contains all the three
characteristics listed above. It is user friendly as well.
6.7 HARDWARE CONSIDERATION
The minimum computer hardware requirements to ensure that the
proposed system will run properly is listed below:
s Computer on the Microsoft Hardware Compatibility List.
s Pentium 100 MHz.
s 1 GB hard disk.
s 16 MB RAM.
s 3.5-inch 1.44-MB floppies drive.
s Super VGA video adapter.
s Super VGA monitor.
s An 80-column printer.
s Microsoft mouse or equivalent pointing device.
s U.P.S. (For un-interruption of power supply)

52
6.8 SOFTWARE CONSIDERATION
To execute properly the source program, which is developed in
Visual Basic, the following software must install in above-mentioned
hardware:
s Visual Basic 6.0 Enterprise Edition.
s Microsoft Windows 98 or Microsoft Windows NT server 4.0 or
Windows NT workstation 4.0
s Anti Virus Guard and Toolkit

7.1 INTRODUCTION
Implementation means the process of transforming of present
manual system into a new computerized one. There are several options
are available for conversion. In data processing, conversion is defined as
placing the system into operation and the process of changes:
s From one data processing to another.
s From one form of representing to another.
Implementation of a project involved activities are planning and
scheduling of the implementation process, organizational planing and
personnel administration, final system design and testing, establishment
of standard of performance and control procedures, and conversion from
old to new system. The most considerable process concerning
implementation phase is the conversion plane that discussed in detail.
7.2 CONVERSION
Conversion refers to those activities necessary to transfer
operations from old system to new system. Conversion to the new
system involves several activities like equipment conversion, file
conversion, and procedure conversion. There are several conversion
option available that will reduce the risk of mishap in the new system.
There are four basic patterns when implementing the new system.
1. Direct conversion.
2. Gradual conversion.
3. Parallel conversion.
4. Pilot conversion

55
The main purpose in conduction comparative study is to argue for
one method of conversion over the other by studying keenly advantages
and limitation of either conversion method. An implementation phase is
rigidly based upon this comparative study.
7.2.1 DIRECT CONVERSION
Direct conversion method stresses upon the introduction of a
completely new system without any reference to the existing system. The
old system is abandoned and the new system becomes completely
operational. This method is suitable when the new system is entirely
different from the existing one. This conversion method is usually the
least expensive and most risky of all the conversion methods.
7.2.2 GRADUAL CONVERSION
Gradual method allows one program at a time to replace an activity
of the existing system. Gradually, the present system is overthrown by
the newly designed system. Small-scale operations are conducted first to
confirm that this changeover will be successful. When the new system is
completely tested, the old system is not used any more and the new
system is completely taken over. This process is continues until the new
system is fully implemented. Both the risk and cost of conversion are
medium in this method.
7.2.3 PARALLEL CONVERSION
In parallel conversion method, both old and the new system are
adopted simultaneously. Data is processed or moved through systems
concurrently and only when the new system is checked, the operation of

56
the old system is abandoned. The safest approach to conversion is to run
both new and old systems at the same time, until it is satisfactorily
established that the new system is producing reliable results. It provides
the old system as a backup in case the new system is failed. This
conversion method is most expensive and less risky than all other
conversion methods.
7.2.4 PILOT CONVERSION
In pilot conversion method, new system is implemented in parts,
the system is implemented in the while organization. Pilot conversion
method therefor, is a combination of the direct conversion and parallel
conversion. Both the cost and risk in this conversion method are
medium.
7.3 PROPOSED CONVERSION METHOD
The most feasible conversion method that suits the organization is
the parallel conversion. It is selected because it provides opportunity to
compare the results of the existing system with those of the developed
system. Another advantage of this approach is that the risk of failure is
covered. Although this implementation approach is more expensive and
increases additional workload, the old system will be safe and the
procedure will be followed for some time until it is confirmed that the
newly designed system is working perfectly.
7.4 TRAINING OF PERSONNEL
Software development is quit user friendly, so that any person can
obtain the require information efficiently from the database, after only

57
few hours of training and practice of the new system. However, a
comprehensive lecture to familiarize the staff with Windows 98 and
Visual Basic 6.0 will also help in better understanding of the system.
