Several tools and techniques are commonly used in SPC to gather, analyze, and interpret data:
Control Charts: Visual tools that display process data over time and help in identifying trends and variations. Cause-and-Effect Diagrams: Also known as fishbone diagrams, these help in identifying potential causes of process variations. Histograms: Used to visualize the distribution of data points. Scatter Diagrams: Show the relationship between two variables and help in identifying correlations. Check Sheets: Simple tools for collecting and recording data in real-time. Pareto Analysis: Helps in identifying the most significant factors contributing to a problem.
