7QC Tools
7QC! It stands for the Seven Basic Tools of Quality Control. These are a set of powerful graphical techniques used to analyze data, identify problems, and improve processes in various fields. They are considered foundational tools in continuous improvement methodologies like Six Sigma and Total Quality Management (TQM).
Here’s a Quick Overview of The 7QC Tools:
- Check Sheet: A simple form for collecting data on specific occurrences or defects.
- Fishbone Diagram (Cause-and-Effect Diagram): Visually maps out potential causes of a problem, helping to identify the root cause.
- Histogram: Displays the frequency distribution of data, showing how often different values occur.
- Pareto Chart: Highlights the most significant contributors to a problem, based on the 80/20 rule.
- Scatter Diagram: Shows the relationship between two variables, helping to identify potential correlations.
- Stratification: Breaks down data into smaller groups based on specific characteristics, for more focused analysis.
- Control Chart: Monitors process stability over time, identifying when performance deviates from expected levels.
