AbSTRACT
This research work is based on the construction of
control chart for quality characteristics of Coke liquid (Sodium content, Sugar
content and Volume) which may be used for control of future products of the
Coca-Cola Company. Secondary data collected from Coca- Cola Company, Idokpa,
Benin City Plant was analysed using Control Chart for process variability and
process average. Through the application of statistical Quality Control
technique, the product quality was examined and process control was established.
The results of the analysis show that both the process variability (that is
Standard deviation and Range) and the process mean () are under Statistical Control in all the three Quality
characteristics considered. The Statistical Quality Control (SPC) technique is
a very useful tool for checking the quality and standard of a production
process. Thus, it is used to confirm the quality level of the production
process in the Coca-Cola Company.
