This PPT slide, part of the 62-slide Six Sigma - Measurement Systems Analysis PowerPoint presentation, focuses on the concept of measurement system discrimination, emphasizing the precision and accuracy of measurement tools. It outlines the importance of decimal places in measurements, indicating that the number of decimal places should be sufficient to capture variations in specifications or processes. The guideline suggests that increments of measurement ought to be approximately one-tenth of the width of the specification or process variation. This principle is crucial for ensuring that measurements are reliable and meaningful.
The slide includes specific examples of measurement tools and their resolutions. For instance, it notes that a digital readout can resolve to 0.001 units, which highlights the tool's precision. It also mentions a dial indicator that may round to 0.1 units, indicating a potential limitation in its measurement capability. Furthermore, the strip chart is referenced, stating it may show variations of 10 units or less, which could affect the granularity of data analysis.
The concept of poor discrimination is introduced, suggesting that it can be equated to excessive round-off error. This point underscores the need for careful selection of measurement systems to avoid inaccuracies that could lead to flawed decision-making. Overall, the slide serves as a guide for organizations aiming to enhance their measurement systems, ensuring they are equipped to capture the necessary data with appropriate precision.
This slide is part of the Six Sigma - Measurement Systems Analysis PowerPoint presentation.
