N2 - In this paper, the objective of the study is to propose a modified Poisson Exponentially Weighted Moving Average (EWMA) chart by Improving Square Root Transformation, namely ISRT c EWMA in order to detection a change in Poisson observation. The performance of this control chart is compared with ISRT c and EWMA charts in term of detection of a change in parameter by using the Average Run Length criterion. We compare the performance of the ISRT c EWMA chart with ISRT c chart and EWMA chart by using ARL criteria. The numerical results also indicated that ISRT c EWMA chart is an effective alternative to the traditional EWMA control chart small shifts detection.
