Based on your chart, is there any statistical evidence of either a downward trend or a beneficial process shift? Is it OK to take the average of all the data? Sketch a control chart. (Overall average = 1.53) Is a quarter of zero events a common or special cause? Should it be celebrated? Will the board's "tough" goal of \"no more than one never event per quarter\" and special reports to them with action plans when two or more occur be helpful in improving safety? What might be a productive strategy at this point? One person wanted more data. With a lot of difficulties. we were able to obtain two more years of data - eight more quarters: 1,0, 3, 4. 0, 0, 3, 1 Adding these data to the beginning, re-sketch the run chart. Does this help you gain additional insight? Based on this analysis, re-construct the IChart (control chart). Do these two charts suggest how these additional data might prove to be helpful
