This research study examined the effects and possible solutions of product quality control as it affects the ordinary customer using Cadbury Nig. Plc as a case study. The research study was aimed at evaluating the product quality and customer satisfaction on the growth and profitability which the organization achieves. Also, the effectiveness of product control on customer satisfaction was also addressed, and analyzed respectively. This information was analyzed with the aid of SPSS v 18.0 on different tables and simple random sampling technique was used. The study is limited by time, which is the school calendar year, coupled with the cost involved in conducting such enormous task. The findings of the study reveal that there are several quality control checks and balance which should be put in place for thorough and in depth satisfaction of the final customer. It also posits generally three processes to achieve quality at a standard rate, these include: inspection of incoming Raw materials, inspection of work in progress and the final inspection of incoming raw materials. Interpersonal relationship amongst consumer’s using a definite product also contribute to innovation and better quality of a product through purchasing. The study recommended that management should control and maintain equipment used for production in the organization.

According to Fagbohungbe (2009) defines production as the “process of designing, operating and controlling a productive system capable of transforming physical resources and human talent into needed goods and services”.

Although, some prefer the label production/operations management, the more global term of production used here is to emphasize that production system generates intangible services as well as tangible goods.

Lawal (2007) states at least four reasons why it is important that you know something about production management, production is a core organizational function. The production function commands the flow of resources through the organization. Society depends heavily on the output of productive organizations and the production function is tied to many serious societal components.

A typical operation or production manager views organizations as productive systems, complete with inputs, a transformation process and output. The transformation process consists of interrelated parts, each depends on the other. Among the important parts of productive systems are these activities listed below, (Enikanselu, and Oyende, 2009)

Product design, production planning, production scheduling, production control, purchasing and material management inventory control, work flow layout and production or out put forecasting and quality control.

Together, these activities let managers carry out their economic function of transforming resources into useful goods and services.



Most organization have nothing to do with company product policies, which could not be visualized as determinants of the product that could be produced, the goals of the organization have not attained the optimum product line. The changes available resources as well as dynamics of the market conditions. In achieving optimum in product competition, certain variables such as composition of product line, dynamism of product attributes are considerations, the selection and design of the particular products and services offered. It was finalized through assessment of interaction between the original concepts, estimated costs of operation, equipment configurations and alternative job or work crew designs. Capacity planning decisions that also determines the location for warehouse and branches and a growth plan, a supply, storage and logistic system (Afewape 2007)

The mature overall system design was rendered in terms of designs for the modular branches. The component of the design included workflow layout and architectural plans. A labour staffing plan that specified just how each operation is to be carried out, including labour time standards, a materials flow plan and layout and, the central warehouse design including storage layout and logistics supply system, the production operation layout, equipment specification, a schedule for the acquisition of property and the building of branches, and a complete financial analysis (Sanyaolu, 2005).

In analyzing what was done and how it was done, it appears that we employed an interactive design process, involving design and redesign to take to account of various interactions. We employed long-range planning concepts, prediction and forecasting techniques, layout planning, equipment justification techniques, behavioural work concepts, product and service analysis and waiting line methods and concepts (Karimu, 2000).

For an organization to be successful, the conception of the process and facilities product design had to represent an integrated view of the conversion process for the system as a whole. In reviewing the longer-term operation decisions, we must realize that they are very significant to the future of the organization.

The decision set against the basic approach to supply distribution and operations for some time to come and committing the majority of the available capital of the enterprise. The key decision that set the design of the productive system are: The design of the product/service bundle to be offered finalized through an interactive process.



  • To examine the effectiveness of product control on customer satisfaction.
  • To determine the efficient and effective competitive advantage on                                                                                                  Customer interest.
  • To assess new product control development programmes on customer satisfaction
  • To evaluate the product quality and customer satisfaction on the growth  and profitability which the organization achieves.



  • What is the effectiveness of product control on customer satisfaction?
  • Does efficient and effective competitive advantage affect customer interest?
  • Does new product control development programmes have impact on customer satisfaction?
  • Does product quality and customer satisfaction affect the growth and profitability which the organization achieves?



Hypothesis 1

Ho: Product quality control will not affect customers’ satisfaction.

Hi: Product quality control may affect customers’ satisfaction.

Hypothesis 2

Ho:     Product quality control has no significant impact on customers’ satisfaction

Hi:       Product quality control has significant impact on customer satisfaction.




The significance of the study is to ensure that organization create better image for the customer. The study will help the organization in ways of controlling their activities in respect to high product standard. Customer satisfaction with performance measure of the company is another significance of the study.

Hence, the product quality and customer satisfaction survey would give a comparison test to validate programme performance measures with an organization. This study will also be useful to students who patronize the product or service, and the organization about the relevance of product quality control tools as inducing factors to consumer patronage of product and the importance of quality control in everyday activities on campus.



The scope of this study is limited to CADBURY NIG. PLC.  in order to find out the relationship between product quality control and customer satisfaction. The staff of the company will be used as a study population.



The research work will be limited to CADBURY NIG. PLC. Especially,the production, sales & marketing, Research and Development and human capital department. The limitations of this study include: Time constraints, Mobility, Financial Constraints and Non-Flexibility of respondents.
