ABSTRACT

In any major manufacturing companies, inventory control is essential parts to check and carry out inventory adequately for proper recording. That is why in this subject topic we choose to carry out study on the impact of inventory management and control system in the performance of a manufacturing company in Nigeria. Which a case was SIBA water company no 105 Uyo Road, Ikot Ekpene Local Government Area. In order to carry out this study successfully, the work was divide into five chapters, while chapter one was on introduction and background of the study, chapter two reviewed of related literature on the subject matter, chapter three was on research design and methodology adopted in carrying out this research while chapter four was a data presentation, analysis and interpretation, while chapter five gave the summary of the work done. similarly, in SIBA water company, sample and sampling techniques were used which we have 65 and in population of the study we have five (5) department in that company which namely; Account section, purchasing officers, Transportation/Maintenance officers, Marketers, and Administration departments. Method of data analysis was chi-square method. Above all, questionnaire were administered to a few selected people in Ikot Ekpene and environment and a total number of sixty five (65) copies of the questionnaire were sent out to be completed by the people but a total of fifty five (55) copies were returned as population study. To this ends, the study revealed the following as major impact of inventory management and control, it enables the production process to flow smoothly thus enabling customer’s orders to be meet promptly and reduces the cost of carrying excessive inventories. That the inventory management techniques used by different manufacturing enterprises includes perpetual inventory review method, just in time inventory model, A.B.C analysis inventory models and a combination of modern and traditional methods that the problems inherent in holding inventories in manufacturing enterprises are in adequate warehouse facilities with the required infrastructures, risk of deterioration in the value of stocks, inadequate electricity and other amenities to keep inventory items in good form, inadequate managerial and technical know-how. It was recommended that management of manufacturing enterprises should make provision for adequate warehouse facilities, equip same with adequate infrastructure needed to keep stock in good state. Also, government should overhead the dilapidated economic and social infrastructures in order to reduce the cost of doing business in Nigeria as well as ensure full employment of factors of production which will bring about improved productivity in the country. Finally, it was recommended that manufacturing companies should train staff for/seriously development in our country.

CHAPTER ONE

INTRODUCTION

1.1   Background of the Study

When scholars first introduced the word “inventory”, they use the word stocks that are kept on store for use as the need arises. However, inventory includes all those goods and materials used in the production and distribution processes. Raw materials, components parts, sub-assemblies and finished products are all part of inventory as well as the various supplies required in the production and distribution process.

Inventory (or stock control) is defined by Jessop and Morrison (2010) as the operation of continuously arranging flows of materials so that stock balance are adequate to support the current rate of consumption, with due regard to economy.

Inventory ties up capital, use storage space require handling, deteriorate, sometimes become obsolete, incur taxes, require insurance, can be stolen, and sometimes are lost. Furthermore, inventory frequently compensates for sloppy and inefficient management, including poor forecasting, haphazard scheduling and inadequate attention to setup and ordering process. In other words, inventory may hide inadequacies and allows management to ignore them, in such cases inventory increases cost and productivity without enhancing net income, it is a liability regardless of where it is carried on the organizations balance sheet. In addition, if an organization has the wrong items in inventory, the situation is worsened. However, the benefits of a properly managed inventory outweigh the costs of maintaining it. The absence of the appropriate inventory will halt a production process. Lack of competent parts will short down an assembly line with partially complete ones collecting dust.

An expensive piece of earth-moving requirement may be idle by lack of an inexpensive replacement part. A patient may die due to the unavailability of plasma. The learning process will be hampered by the no arrival of texts. And in many cases, good customers may become irate and take their business elsewhere if the desired product is not immediately available. The availability of the right items at the right time and in the right place supports the organizational objectives of customer’s service, productivity, profit and return on investment. This is true in manufacturing, wholesale, retail, healthcare, and educational organizations. An inventory can be an asset in the full sense of the word. Measures of performance and productivity may differ among organizations, but all need adequate inventory management.

Also, it includes the related process of provisioning, which is the determination of requirement in advance, stock control is a way of regulating the levels of supplies in stock to avert stock excesses or deficiencies. It also involves techniques used to ensure that stocks are kept at levels that guaranteed maximum service levels at minimum costs.

Stock control involves the following processes

  1. Assessing the items to be held in stock
  2. Deciding the extent of stock holding of items individually and collectively
  3. Regulating the input of stock into the store house
  4. Regulating the issue of stock from the store house

All business and institution require inventories, often they are substantial part of total assets. Financially, inventories are very important to manufacturing companies, on the balance sheet, they usually represent form 20% to 60% of total assets, inventory are used, their value is converted into cash which improves cash flow and return on investment.

There is a cost for carrying inventories, which increase operating costs and decreases profit. Good inventory management is essential, inventory is an idle stock of physical goods that contain economic value and held in various forms by an organization in its custody awaiting packing, processing, transformation, we or sale in future point of times.

Since the inventory or stock in the company or firm determine to a greater extent the prosperity and success of a firm. Therefore, there is need for good management and control of inventory in order for it to bring a more positive impact to the firm or company. Some scholars also defined inventory management as an effort for planning and controlling of inventory from the raw material stage to the customers for consumption or further production.

According to Breton (2007) is a major interest of purchasing managers in many industries, the inventories comprises a substantial share of the firm assets. If the productivity of the inventory asset can be enhanced, improvement will go directly to the bottom line. The function of purchasing is directly influenced by inventory management decision

To get the most value out of our resources, we must design production process that make product more effectively. Once the process exists, we need to manage their operation so that they produce goods most economically. Managing the operation means, planning for and controlling the resources used in the process.

If the right stocks in the right quantities are not available at right time, the process cannot produce what it should, labour and machinery will be poorly utilized. The profitability and even the existence, of the company will be threatened inventory management and control system are designed to monitor product availability, determining purchasing schedules and cycle out obsolete or unsold product.

Others scholars like “Anderson” also regard inventory management is the art and science of managing, to have the right product at the right time and right place in exactly the right amount, at the best possible price. It held to reduce the amount to time that product sits on your shelves.

To this ends, to keep inventory investment and inventory losses at a practical minimum. In as much as objective (i) is achieved by keeping inventory, this should not be done at a loss. Sound purchasing and supply management aims at efficient management and control of inventory levels in the overall interest of an organization. When optimum inventory levels are maintained, efficient utilization of capital is achieved with a resultant attractive return on investment (ROI). A good inventory system ensures the development and maintenance of good stocking policies, records and procedures which ultimately combat fraudulent supply practice

Therefore, every organization constantly strives to maintain optimum inventory to be able to meet its requirement and avoid over or under inventory that can impact the financial figure and profitability, should implement this system.

1.2   Statement of the Problem

The following problem was identifiable in the organization of my case study which retains my desire to embark on this research.

Lack of Continuous arrangement of flows of material

This is the major problem of the organization, the operation of continuously arranging flow of materials so that stock balances are adequate to support the current rate of consumption with due regard to economy is unavailable.

Low Increment in cost of goods sold

Inventory management and control system is the only measures for lowering cost of goods. Since they is absent of inventory management and control system, increase in cost of goods sold become obvious.

High amount of obsolete and unsold product

A well design inventory management and control system, give the manufacturing company ability to reduce the amount of time that product sits on the shelves. But since they is no effective inventory management and control system in this organization, this give room to increase in the number of obsolete and unsold product.
