The sequential probability ratio procedures of Statistical Inference are made use of in construction of a Cumulative Sum Control Chart for a variable process characteristic. The distribution of process variate is log-logistic distribution. The construction of mask and values of average run length are also presented. Such a chart is useful in early detection of shifts in the process average.
