ABSTRACT

This study examines the essence of effective inventories control and management to manufacturing companies with particular emphasis on Ama Greenfield Breweries plc. The aim of this study is to investigate and ascertain areas of lapses by the company and offer effective ways and solutions in which the manufacturing company can explore the services of inventory management to effect its objectives. In carrying out this study, various research instruments such as questionnaires and oral interview were used to collect data from respondents and a research design was adopted with a sample size of 52. The statistical tool used for this work is Chi-square. Based on the analysis, it was discovered that inventory management plays a vital role in the manufacturing company. A well functional inventory management following the recommendations can bring about proper management thereby enhancing proper and effective production and it will equally ensure the effective, efficient and adequate use of materials and resources in the manufacturing company.

CHAPTER ONE

INTRODUCTION
1.1 BACKGROUND OF THE STUDY
Inventory is one of the resources that are managed by business
organizations and it was first recorded in 1601. The need for inventory
control cannot be overemphasized as it is a means for improving the
performance of manufacturing industries. Inventory can be defined as a
record of a business current assets including property owned, merchandise
on hand and the value of work in progress and work complete but not sold
and it is classified as a current asset because it can be turned into liquid cash
within a short period of time. Inventory has created a great impact on the
profitability of the manufacturing firm which resulted to the deep research of
this topic. Effectiveness of inventory management in a manufacturing
company.
Inventory plays a major role in the operation of many businesses and
manufacturing companies. In manufacturing, inventories of raw materials
allow companies to operate independently of their sources of supplies. Day
to day operation are not dependent on deliveries from supplies since stock of
the necessary mateials are maintained and used s needed. Without inventory
2

control, millions of naira could be lost year because of non accountability of
stocks and inaccurate checks and balances.
The process of control and management of inventory is a very
important factor in the success or failure of any business for example, little
stock will result in stock out which will disrupt the production distribution
cycle that is crucial to the survival of all manufacturing companies while
too much stock will tie down the resources of a company. Poor or
inadequate inventory management can present a serious challenge to the
productive capacity of a manufacturing organization. In addition to raw
materials and finished goods, many companies also maintain items of assets,
property, inventories of work in progress, office supplies, business firms and
general operation supplies.
Inventories often constitutes the most significant part of current assets
of large companies. In the public limited companies, inventories are
approximately 60% of current assets on the average. The US Burean of the
census stated that inventory and accounts receivable ate the two largest
accounts of equal magnitude and together they comprise almost 80% of
current assets and over 30% of total assets for all manufacturing companies
in 1982.

Considering the large sum of money that are committed to the stocks
of raw materials, work in progress and finished goods, it is therefore of
paramount necessity that these stocks be managed efficiently and effectively
in order to avoid the jeopardizing of the profit position of the firm.
In inventory, there is an optimum level therefore inadequate inventory
causes loss of sale and disrupts the production process while excessive stock
level leads to unnecessary carrying cost and obsolescence or spoilage risks.
According to Charles T. Horngren (2007), the optimum inventory. Level lies
between the inadequate inventories and the excessive inventories. Inventory
management aims at maintaining an optimum inventory level that will be
carried at the least cost.

1.8 LIMITATIONS OF THE STUDY
Some limitations and factors in this research study are as follows:-
i. The time required for the research and the submission of this work
is very short and the researcher was unable to go through all
manufacturing companies.
ii. Financial constraints:-Finance which is the most important
resource for this work was not readily available.
iii. Limited exeat:-Due to the fact that exeat is very difficult to get in
school, proper research was not carried out and this affected the
integrity of the results achieved.
iv. Unco-operative attitudes of some of my respondents:- The
management of Ama Breweries prohibited its employees from
giving out information about the company to outsiders without
adequate permission from the management and even when this
permission was obtained at the long run, many vital information
