This paper studies the application of processcapability indices in the evaluation of a process with asymmetrictolerances. The analyzed collected data of the cleaning liquid “Zahi”, wasused to investigate the ability of the filling process to meet the requestedspecifications. Matlab software was used to plot ̅ ̅ control charts,normal probability, and histogram of the data gathered from theproduction line and further performed statistical calculations. It wasobserved from the control charts that the filling process is under control.In addition, it was revealed by the process capability indices that theprocess of filling the cleaning liquid bottle is not fitted with the targetvalue but it is adequate.
