XbarR, XbarS, Individuals, n, p, u, and np charts should be regularly updated after their initial creation, while also ensuring that any outliers are identified and displayed independently, so they do not interfere with the established control limits. Additional tools include histograms, capability analysis (Cpk), scatter plots with regression fitting, Pareto charts, dot plots, box plots, multiple regression analysis, hypothesis testing, confidence intervals, and calculations for sample sizes. Furthermore, it is essential to conduct measurement system analysis (Gage R&R) applicable to both quantitative and binomial data, along with creating cause and effect diagrams, main effects plots, cusum charts, product capability assessments, FMEA, and distribution calculators to enhance data-driven decision-making processes. Each of these analytical methods contributes to a comprehensive understanding of the data and its implications for quality control and improvement initiatives.
