ABSTRACT
The overall goal of this research is to look into the effects of production planning and control on the manufacturing process, utilizing Nigeria Brewery in Lagos State as a case study. The study used a survey research methodology, and seventy-nine(79) participants were chosen for the study from Nigeria Brewery Lagos State personnel and management using a suitable selection technique. Well structured questionnaire was issued to the respondent of which 70 were retrieved and validated for the study. Frequency counts and simple percentages were used to assess the data. The Chi-Square statistical package for social science was used to conduct the hypothesis test (SPSS v.23). The study’s findings reveal that quality control implementation involves several methodologies, including the planning phase, procedure phase, and organizational change phase. As a result, organizations that are committed to quality control implementation tend to maintain high quality standards in production, which gives the business direction. As a result, the study suggests that proper production planning and management be carried out in manufacturing businesses by taking into account all components essential for optimal output.
CHAPTER ONE
INTRODUCTION
Background of the study
As a result of the pressures of globalization, manufacturing companies are focusing on three primary competitive arenas: quality, cost, and responsiveness. Any manufacturing company’s success hinges on its ability to plan and control production. The Manufacturing sector includes businesses that turn materials, substances, or components into new products by mechanical, physical, or chemical means. Customers have stated their needs and expectations in terms of real or estimated needs and expectations, and manufacturing businesses want to meet those needs and expectations. Furthermore, as a result of recent technological advances, manufacturing organizations must make technical improvements to their manufacturing systems in order to adjust their manufacturing program and improve goods while lowering manufacturing costs.
Complex, dynamic, stochastic systems are required for these varied facilities. Workers, supervisors, engineers, and managers have devised a plethora of ingenious and practical methods for controlling the production process and activities since the dawn of organized manufacturing.
In order to survive and be able to provide customers with good products, manufacturing organizations are required to ensure that their processes are continuously monitored and product quality are improved. Various quality control approaches are used by manufacturing companies to improve the quality of their processes by reducing variability. Quality is described as meeting a customer’s or a specification’s requirements without any flaws. When a product performs as predicted and is dependable, it is said to be of high quality. Quality control is the process of ensuring that the things produced are of the best possible quality. Quality control and improvement, according to Demirbag (2006), is one of the most critical components in any firm. Successful businesses recognize the significant impact that customer-defined quality can have on their bottom line. As a result, many competitive companies are establishing entire quality control departments into their organizations, whose policies are geared at delighting customers by providing standard quality products, exceptional services, and timely delivery.
Statement of the problem
Every manufacturing process necessitates the input of men, materials, money, and machines. As a result, any business that produces a product or provides a service must be responsive to market demands as evidenced by a steady stream of consumer orders. According to Jain and Aggarwal (2008), for optimal effectiveness, this must be done in such a way that customers’ requests are met while manufacturing activities are carried out efficiently. Although a variety of factors have been blamed for substandard products in the manufacturing industry, Arora (2009) points out that the quality of goods is ultimately determined by customers. This is due to effective quality, which influences the rate of productivity and, as a result, becomes an important factor in organizations and contributes to economic growth. Surprisingly, the use of inadequate basic materials in the manufacturing process has resulted in the creation of substandard products in the Nigerian sector, causing the product to fail to meet the desired quality of specification. Some manufacturers make substandard items that aren’t the same as the ones they submitted to regulatory organizations for certification. As a result of customers’ inability to purchase such poor products, organizational productivity has suffered. This is due to effective quality, which has an impact on productivity and, as a result, has become a key factor in companies and contributes to economic growth. Surprisingly, in the Nigerian industry, the use of insufficient basic materials in the production process has resulted in the manufacture of substandard products, causing the product to fail to satisfy the intended quality specifications. Some firms produce poor products that aren’t the same as the ones they submitted for certification to regulatory bodies. Organizational productivity has decreased as a result of customers’ inability to acquire such bad items.
Objective of the study
The study’s main goal is to look at how quality control is planned and implemented in a manufacturing organization using Nigeria Brewery as a case study. The following are the objectives of this research:
To examine the techniques of quality control applicable in manufacturing industry.
To ascertain whether inspection of technique will affect production control
To ascertain if there is any effect of quality control technique on product quality
Research Hypothesis
HO1:Production control is significantly improved by using inspection techniques.
HO2: Quality control technique and product design have a considerable favorable link.
Significance of the study
The findings of this study will inform industry managers and other stakeholders in the manufacturing sector on how production planning and control can substantially cut an industry’s operational costs. It will also teach about the impact of production planning and control on the effectiveness, profitability, and productivity of organizations. This research will add to the body of literature on the impact of production planning and control on operational costs, assisting in the strengthening and promotion of organizational development. The study would serve as a reference material for academics and students interested in conducting additional research in a connected topic.
Scope of the study
The scope of this research is limited to quality control planning and implementation in a manufacturing organization. The research will also look into quality control techniques used in the manufacturing business, see whether inspection techniques affect production control, and see if quality control techniques have an impact on product quality. However, the research is limited to Nigeria Breweries in Lagos State.
Limitation of the study
The researchers ran into some minor roadblocks while conducting the study, as with any human endeavor. Because there was a scarcity of literature on the subject due to the fact that it was a new discourse, the researcher had to spend more money and time sourcing for relevant materials, literature, or information, as well as in the data collection process, which is why the researcher chose a small sample size covering Nigeria Breweries. As a result, the conclusions of this study cannot be applied to other Nigerian manufacturing firms.
Definition of terms
Planning is the process of considering the activities needed to achieve a specific objective. Foresight, the fundamental capacity for mental time travel, is the foundation for planning.
Production: Production is the process of merging numerous material and immaterial inputs (plans, know-how) to create a consumable product (output).
Manufacturing Process: Process manufacturing is a method of producing items by employing a formula or recipe to combine suppliers, ingredients, or raw materials. It’s commonly utilized in industries that manufacture large amounts of items.
