Statistical Quality Control On Nigerian Breweries Product (Star).

ABSTRACT

This work is geared to unveil the measured quality characteristics of Nigerian Breweries product (Star), hence to construct control charts that could be used to study the production processes of the product (Star). Statistical quality control technique used in this work is process control. It was carefully observed that both the process Range and the process mean of the five quality characteristics of Nigerian Breweries product (Star) are not operating on a stable process control. But for a more stable process range and process mean, the points that fall outside the warning and action limits were discarded and the revised control Limits constructed. Since it was concluded that the company operates in an unstable quality standard for the product (star). Then for a more improved quality, the company should consider operating a quality control chart for the product (star) and some others.
