CHAPTER ONE

1.0 INTRODUCTION 
1.1 BACKGROUND OF THE STUDY 
A trend in the past has been for companies to hold some level of stock than preciously did. Hence companies gas fund that they can sometimes reduce the lead time required to obtain materials and to produce products, so that they can operate with less inventory and skill serve their customers effectively.
Stock is idle resources hold for future use. Whenever the inputs and outputs of a company are not used as soon as they become available, inventory is present. Services operation and jobs tend to have small investments in stock. For may companies, however, stocks account for a large percentage of assets this need for stock control. 
Chilaka (2006:128) times stock control as the means by which materials of the correct quantity and quantity is made available and as at when required with due regard to the economy in storage and ordering cost, purchasing and working capital.
Carter and price (1996:139) defines stock control as the process of ensuring that the stock held by the organization is supplied to those parts of the operations that required the items (ie production, distribution, sales, engineering etc).
Henritz and Farrell (1990:100) defines inventory stock control as the assurance of having the items at hand when needed and afford the added protection of reserve, stocks, theoretically untouchable but practically serving to fill needs when extra ordering demand develops or when correct procurement fails.
Organizations that have stocks has the advantages of assessing items to be held in stock, the extent of stock holding operational needs time required to deliver goods, availability of capitals, cost of storage, regulation of the input of s tock into and from the stove house through these, it is possible for firms to adjust continuously the quantity and value of stock held to com firm with circumstances of control. 
According to monk (200:148) inventory need to be effectively managed, if efficient operation is to be achieved, due to its initial nature, the mode of control and management of inventories can be a factor in the success or failing of manufacturing company concern. 
He pointed out that insufficient inventory can seriously disrupt the product distribution cycle that is so critical to the survival of all the manufacturing organization. On the other hand excessive inventories can cripple a firm as felons and this endanger it’s liquidity position. Either poor inventory management can present a serous challenge to the productive capacity of manufacturing organization.

(7) Surplus: A useable materials, equipments or parts including capital equipment which are in excess of normal manufacturing operating or repair equipments.
(8) FIFO: First in, first out 
(9) LIFO: Last in, last out.
(10) Obsolete: This is where an item is completely usuable by the organization.
(11) Stock: these are inventories or stores used within the production system.
(12) Productivity: This is the rate or amount of goods produced compared with low much input (time, money ) used or needed to produce then. 
(13) Obsolescent: When stock is going out of use but is not yet completely unusable. 
(14) Redundant: When item in stock is more than what is reasonably necessary to provide an adequate service to the production or operational activity, the excess over the normal holding.
(15) Discrepancies: This is when the amount of stock found by psychical check fails to correspond with the balance on the stock records.
