Most of the statistical process control (SPC) techniques are developed for the assumption that considers the measured data to be normally and independently distributed. In real world applications of SPC, however, this assumption is very far from the truth due to the dependence of data on itself. However, quick effective and minimum cost of product inspection can be done by statistical quality control. In this study, quality control with the operating characteristic curve and practical samples in the forest products area was investigated. Results thickness of Medium Density Fiberboard (18mm) from SFC and Divapan organization were used for obtaining the operating curve. It was observed that process SFC and Divapan in organization are under the control according to characteristics curve.
