Abstract: Daily wear and tear of industrial machinery, while performing its intending functions, could not only affect the quality but also affect the output performance. In this study, the functional performance of bottle washing and filling machines in a local beverage industry is assessed. This was done using output data from both machines for the period of two months for limca and goldspot drinks. Analyses of the data were done via the statistical tests such as t-test and F-test. The results of the tests showed that bottle washing machine output performance is satisfactory in washing both limca and goldspot bottles while, in filling machine, there is a gradual shortfall in performance. This calls for immediate attention in term of putting in place a formidable replacement plan.
