Hence the scope of the research cover every activity which has to do with production planning and control. The work covers statement of the general problems, research objectives, scope of the study, significance of the study and limitation of the study. Also diverse view of authors on production planning and control and other related areas in review. The research work employs the descriptive method for the purpose of an in-depth investigation. A sample size of 70 respondents was selected from the total population of 180 staff, questionnaire were administered to them, oral and verbal interview as well as obtaining information. Hypothesis H0 and H1 formulated on using effective production planning and control to minimize defective product in production performance. Date collected were presented and daily analyzed in tabular format using percentages, other findings of the studying centered on the required raw materials used by the organization but sourced outside the country, government policies such as hinge tax payments, customers and excise charges contributes to high production cost with locally sourced raw materials not maintaining a stable price from time to time with future plans having limitation due to some government regulations, economic downs turn, environmental factors technological changes, competitors actions. The study also brought to the fore the importance of production planning and control in the role of forecasting in production and operation management. Finally based on the findings a number of quality recommendation were offered to the organization to embrace in raw materials sourcing using alternative means i.e. research and development department, the complete computerization of the control system and other key system should be pursued effectively.

BACKGROUND OF THE STUDY
Production Planning and Control provides the foundation for any effective production management in every organization or manufacturing sector by minimizing defective products is very vital issue to a production managers.
To guarantee effective material flow Production Planning and Control represents the beating heart of any manufacturing process. Production Planning and Control purpose is to minimize production time and costs, efficiently organize the use of resources and maximize efficiency in the work place.
Production Planning as defined by Digreens (2009, pg. 21) “is a set of function concerned with the effective utilization of limited resources (such as raw materials, manpower, machinery etc.) and the management of materials flow through these resources, so as to satisfy customer demands and create profit.
As can be seen in other related field of management, Production Planning and Control plays the primary functions of the production management and operations.
This has prompted this research work to look at Production Planning and Control as a tool for minimizing defective product in manufacturing industries of Nigeria economy as exemplified by Defence Industries Corporation of Nigeria Kakuri, Kaduna. Production is the central focus of any manufacturing concern. It is the platform where the real mix takes place i.e. the conversion of raw materials (in-put, starters) into completed or finished products (output) after a well planned logical form or process production planning incorporate a multiplicity of production elements, ranging from the every day activities of staff to the ability to realize accurate delivery times for the customers.
Modern and improve production is complex hence technologically related operations and administrative activities must be planned carefully to make account and benefits. With an effective production planning cooperation at its nucleus, any form of manufacturing process has the capability of exploit its full potential.
In Production Planning, it not only involves the type of operation to be used but also the order of these operations as well as time which the operation should take and how it should be properly and effectively laid out.
There are different function performed by Production Planning and Control Department of an organization. Procedures may also vary; all the production planning and control department are essentially expected to perform the following functions:
According to Buffa, E.S, Modern Management, New Delhi: Willy 1988 “Production Planning may be defined as the technique of foreseeing every step in a long series of separate operations, each step to be taken at the right time and in the right place and each operation to be performed in maximum efficiency.” It helps entrepreneur to work out the quantity of material, manpower, machine and money requires for producing predetermined level of output in a given period of time.
Routing: Under this, the operations their path and sequence are established. To perform these operations, the proper class of machines and personnel required are also worked out. The main aim of routing is to determine the best and cheapest sequence and to ensure that this sequence is strictly followed.
Routine procedure involves following different activities:
Scheduling: It means working out of time that should be required to perform each operation and also the time necessary to perform the entire series as routed, making allowance for all factors concerned. It mainly concerns with time element and priorities of a job. The pattern of scheduling differs from one another which is listed below:
Loading: The next step is the execution of the schedule plan as per the route chalked out, it includes the assignment of the work to the operators at their machines or work places. So loading determines who will do the work as routing determine where and scheduling determines when it shall be done.
Samuel Elison (1994) in his book, Element of Production Planning and Control, Bombay: Universal Book Co., 1985 says “Production control is the process of planning production in advance of operation, establishing the extract route of each individual item part or assembly, setting, starting and finishing production and releasing the necessary order as well initiating the necessary follow-up to have the smooth function to the enterprise.
Dispatching: Dispatching involves issue of production order for starting the operation, necessary authority and confirmation is given for:
Dispatching is an important step as it translate production plan into production.
Follow Up: Every production programme involve determination of the progress of work, removing bottlenecks in the flow of work and ensuring that the productive operation are taking place in accordance with the plans. It spot delays or deviation from the production plans. It helps to reveal defects in routing and scheduling, misunderstanding or orders and instruction, under loading or over loading of work etc.
Inspection: This is mainly the quality of goods, it can be required as effective agency of production control.
Corrective Measure: Corrective action may involve any of those activities of adjusting the route, rescheduling of work changing the work loads, repairs and maintenance of machinery or equipment, control over inventories of the cause of deviation in the poor performance of the employees. Certainly personnel decisions like training, transfers, demotion etc. may have to be taken alternative methods may be suggested to handle peak loads. The following are required to be able to achieve the activities successfully:
STATEMENT OF RESEARCH PROBLEM
For a manufacturing organization and indeed any other organization besides the general planning and control planning, control of materials is particularly very crucial for its survival hence effective producing planning and control is necessary in every organization.
The success of our present day industries depends on how to effectively utilize and to enhance growth and development and sustain for better industrialization.
Therefore, this research work is concerned with identifying the way in which defective product can be minimized through effective production planning and control in Defence Indus tries Corporation of Nigeria.
To this end, the following questions occupy our mind before the research as problem generally associated on what roel does the choice of production planning and control plays in a Defence industries.
The researcher wants to know why production planning and control is vital and useful in minimizing defective products in Defence Industries.
While there is not standard system in production planning and control which can be universally recommended, even production planning and control system must be designed to meet the particular needs and concern of the manufacturing organization.
OBJECTIVE OF THE STUDY
The importance of production planning and control motivated me to undertake a study of how the principle and techniques of production planning and control are applied in defence industries corporation of Nigeria (DICON), Kakuri Kaduna.
However, the primary concern of this research work is to investigate.
It is hoped that, this objectives when attain will be tremendous benefit to the Defence Industries Corporation of Nigeria (DICON) and Nigeria in general.
SIGNIFICANCE OF THE STUDY
This study will be of great significance in that it seeks to emphasize on:
Finally, it is hoped that the work will serve as a reference guide to students and scholars who ought to use it.
Statement of Hypothesis
This research work constitutes the following statement of hypothesis:
H0: Defective Product cannot be minimized through effective Production Planning and Control.
H1: Defective Product can be minimized through effective Production Planning and Control.
SCOPE OF THE STUDY
The scope of the study is to investigate the effective measure on Production Planning and Control that exist at DICON and the individual production process of each arm and ammunition from start to finish of the detail process in doing so, the researcher will re strict attention to Defence Industries Corporation of Nigeria ordnance factory complex Kakuri Kaduna, Production Planning and Control Department.
LIMITATION OF THE STUDY
The part of any undertaking is not an easy one, constraints, limitation, hindrances, unforeseen problems and stress are generally expected and bound to happen in most research work, thus my research is same and is not exception.
The first problem being in collecting, finding and required text books on the subject matter of the research at the initial stage.
Next problem was time constraint. Time is very important and to get accurate and up to date data but the time allowed for the work is not adequate because being a student, the researcher, at the same time battling with class works, assignments as well as external classroom problems coupled with the global melt down experiencing presently.
Finally, other commitment such as work pressure which also have to be considered.
HISTORICAL BACKGROUND OF THE STUDY
Defence Industries Corporation of Nigeria (DICON) was established by an act of parliament in 1964 to “operate maintain and control factories for the manufacture, storage and disposal of ordnance and ancillary stores and materials; to provide for alteration in any such manufacture, storage and disposal at any time; and for related matters”. As an arm or department under the supervision of the Ministry of Defence, DICON is governed by a Board of Directors, which provides the overall policy direction for the corporation as desired by the Federal Government. The DICON Board is presently constituted as follows:
The Director – General is the Chief Executive Officer (CEO) of the Corporation and is responsible for the day to day running of DICON. The corporation is structured on six (6) professional departments namely:
