Quality control on weights and lengths of kitchen-bar and tablet soap (a case study of j. Udeagbala holdings, plc, aba)
ABSTRACT
This study centers on the application
of statistical quality control techniques to soap production to ensure that the
lengths and weights of soap produced does not deviate from the stipulated
standard. A practical observation on lengths and weights of this product (soap)
were taken and recorded. X-charts and R-charts were used in the analysis to
check whether they conform to specification or not. In this study, the
technique of the statistical quality control called process means and
variability of each of weights and lengths of bar soap and tablet soap. The
ultimate objective is to determine if the production process is in state of
quality control. The X-bar charts constructed for weights and lengths of the
two types of soap all indicate that the process mean is under quality control in
each case. Similar results are also obtained when R-charts are constructed for
both quality characteristics. It is therefore recommended that the company
understudy should maintain quality and encourage rectification exercise when
necessary in order to avoid unnecessary loss of resources.
