The use of alternative control charts for monitoring fraction data is not new: Quesenberry (1991) proposed a Binomial Q Chart to monitor nonconforming fraction using a nonlinear transformation for the control limits and demonstrated that it approximates the Normal distribution closer to the Binomial. Heimann (1996) presented a modification of the p-Chart control limits for large sample sizes (n > 10,000), noting that in this case the control limits are narrow, thus the false alarm rate increases. Schwertman and Ryan (1997) suggested modifications of the np-Chart control limits to fit on the Normal approximation when p < 0.03, while, Chen (1998) proposed an adjustment to the p-Chart control limits and compared them with the traditional p-Chart the Binomial Q Chart using the false alarm rate. Sim and Lim (2008) adapted the attribute control charts to monitor zero-inflated data and used the Blyth-Still interval with 3-sigma to calculate control limits assuming that this data follows a Binomial and Poisson distribution.
