An exponentially weighted moving average control chart for monitoring Poisson data is introduced. The charting procedure is evaluated using a Markov chain approximation, and its average run length is compared to other procedures for Poisson data. Figures are given for the user to select the value of the upper control limit that gives the desired in-control average run length.
