ABSTRACT
The technique of
inventory control is indispensable going by their impact in contributing,
promoting and ensuring efficiency and effectiveness in any organization. In
actual practice the vast majority of manufacturing companies suffer excessive
inventories than are necessary. Therefore, inventory control process is much
more complex than the uninitiated understand. In fact, inventory control is
perceived as little more than a clerical function. This has resulted into lots
of material shortages, high costs and loss of profit. This study provides a
basis for implementing inventory control policies by service companies, professional
managers, especially manufacturers.
The aim of these research
works is to critically assess the impact inventory control has on the profits
of manufacturing companies. Relevant literature on inventory management and
control by various authors were reviewed.
Both primary and
secondary sources of data were used in the course of study. Primary source of
data used was questionnaire while the secondary sources used are, text books
and journals. The chi-square formulae, person product moment correlation
co-efficient, test of significance were employed for effective analysis of data
collected. Data was collected through the distribution of 50 questionnaires to
the staffs of Tower Aluminum Nigerian Plc.
The two hypothesis
formulated were subject to thorough tests and all two hypothesis tested were
accepted. The respondents agreed that inventory control is a contributory
factor to the profitability of manufacturing companies and as such proper
control of inventory of manufacturing companies and as such proper control of
inventory reduces the overall cost. Conclusion and recommendation were also
made as to the acceptance of the alternative hypothesis such as putting in
place all necessary features that inventory control needs to effectively
achieve its purpose in a manufacturing organization.

CHAPTER ONE
INTRODUCTION
1.1 BACKGROUND OF THE STUDY
There is a growing emphasis on the
importance of inventory management in the attainment of organizational goal. In
manufacturing companies where stock of raw materials and other component parts
consists of many different items, the task of maintaining a stock management on
every individual item is obviously difficult if not impossible.
The focus of this project is
therefore the impact of effective inventory management in Tower Aluminum
Nigeria Plc. This study is aimed at identifying the overall impact of proper
and accurate management of stock items together with the recording and
monitoring of stock level, forecasting future demand or production run and
deciding when and how to place the order and how many inventory to carry per
unit of item in other to satisfy the needs and wants of potential customers in essence
of maximizing profit for the organisation.
Inventory refers to the stock of
resources that possess economic value, held by an organization at any point of
time. These resources stocks can be manpower, machines, capital goods or
materials at various stages.
According to wise Greek, inventory is
total amount of goods and /or materials contained in a store or factory at any
given time. It’s necessary for business manager of an organization to know the
precise number of items on their shelves and storage area in order to place
orders or control losses.
The word inventory “can refer to both
the total amount of goods the act of counting them. Many companies take an
inventory of their suppliers on a regular basis in order to avoid running out
of popular items. Others take an inventory of to insure the number of items or
ordered matches the actual number of items counted physically. Shortages or
overages after an inventory can indicate a problem with theft (called shrinkage
in retail circle) or inaccurate accounting practices in an organization.
Inventory simply means a quantity of
goods and materials in the control of an organization held for a time in a
relatively idle or unproductive stage “GREAT MAN”. Management is concerned with
the process of achieving objectives through efficient use of resources and the
planning, organization, coordination, direction, and control of the activities
of people. It is the sum total of all the activities involved in the organizing
men, machines, materials, and money and the maintaining, directing,
coordinating, supervising, and controlling them to produce or provide for a
profit, goods and services which benefit members of the society. “Dr. ADE Oyedijo
2009, Essential of Mgt”
Other functions of management are;
LEADING:
Leading here means influencing people so that they can contribute
positively towards achieving the goal
of maintaining stock at minimum cost.
COORDINATING: Coordinating
here means each department contributing towards the organization goal of
keeping the inventory at minimum cost
DIRECTING:
Directing here means harmonization of individual objectives with that of the
organization so that the goal of the organization to maintaining stock at
minimum cost is achieved.
INVENTORY MANAGEMENT: is very important having direct relationship with production, marketing,
purchasing, maintenance, and financial policies. In view of this, many firm attempt
to control stock in scientific basis by considering the financial effect of all
relevant cost of inventory. Scientific control of inventory is the use of
economic order quantity (EOQ) model.
The overall objective of inventory
management is to maintain stock level so that
combined cost of inventory will be
minimal. The optimum level of the stock depends upon a variety of factor
arising from the interest of the different department involved and the
management should establish an overall policy for stock after considering the interest
of the organization as a whole. Whether as a result of deliberate policy or
not, stock represents an investment to the organization and as with other
investment, cost of holding stock must be released to the benefit to be gained
from holding the stock.
Inventory having the greater' part of
the working capital of most organization, should be managed effectively,
failure to do so will lead to high carrying cost, lost of goodwill high rate of
obsolescence, excess tied up capital, interruption of work schedule in production,
idleness of machine and personnel which leads to low profit and consequently
leads to winding up.
Though the objective of inventory
management is to ensure that stock is kept at optimal level. Nevertheless
departmental managers view this from different
Perspectives From financial point of
view, the aim is to minimize stock holding cost, while adequate stock level
that will facilitate continuous production run is of interest to the production
manager.
To purchasing, the aim is to take
advantage of special buying offer, but this will lead to increase average level
of stock and sales department will want to be able to satisfy all customer
order which will mean high stock of finished goods to provide a buffer against uncertainty
in demand.
It can be seen from the above that
departmental manager's perspective of viewing inventory management are
different but they are all channeled towards organization efficiency.
As aspect of inventory management
that cannot be overlooked is the number of
aluminum manufacturing company should
have and how they should keep the product to maintain these aluminum products.
In this country today where every big manufacturing company rely almost or more
than 70% of its source of power on generator, since generators are expensive to
buy and production run and efficiency in production process. The decision to
buy wholly or jointly remain the decision of the top management of each
organization.
1.2 STATEMENT OF THE PROBLEM
Inventory management is very
essential in any organization setting, because holding stock is just like
holding cash, and cash is life blood of the firm. Also in the context of
inventory management, the organization is faced with the problem of reconciling
two conflicting need; to maintain a large inventory for smooth production run
and to maintain a minimum inventory to maximize profitability by having the
lowest carrying cost.
And the problem associated with the
decision on when and how to order materials for smooth run of the (business)
production.
1.3 OBJECTIVES OF THE STUDY
The primary aim of this project is to
examine the effect a well managed inventory has in a manufacturing company.
Other objectives of the study are as stated below:
(a) To determine the effect of inventory
management in the manufacturing company especially Tower Aluminum Nigeria Plc.
(b) To
enhance the performance of inventory management in an organization.
(c) To reduce risk that are facing inventory
management.
(d) To determine whether there is a problem facing
the inventory management in Tower Aluminum Nigeria Plc.
(e) To map out strategies to train good store
keepers who will manage the stock.
1.4 RESEARCH QUESTIONS
These are the research questions:
(i) Could effective inventory management help to
meet variation in product demand?
(ii) Could effective inventory management enhance
uninterrupted flow of production?
(iii)
Could the stock be controlled in a way
that it will not tie down the capital in an unprofitable venture?
(iv)
