p Chart from QI Macros in Excel Purpose: Evaluate process stability when counting the fraction defective. The p chart is used when the sample size varies: the total number of circuit boards, meals, or bills delivered varies from one sampling period to the next. A fully capable process delivers zero defects. Although this may be difficult to achieve, it should still be our goal. Once we resolve the out-of-control points, we could use the quality problem solving process to begin to eliminate the common causes of defective items. What are the most common types of errors? Why do they occur? What are the root causes of these errors? Boost Your Productivity and Profitability in Record Time with these SPC Tools for Six Sigma and ISO.p charts are just one of the tools included in the QI Macros for Excel SPC Software for Excel.
