QC tools revolutionized the process analysis and leading to process improvement.
In this vlog the following tools are covered.
1. Histogram: The most commonly used graph for showing frequency distributions, or how often each different value in a set of data occurs.
2. Pareto chart: A bar graph that shows which factors are more significant.
3. Cause-and-effect diagram (also called Ishikawa or fishbone diagrams): Identifies many possible causes for an effect or problem and sorts ideas into useful categories.
4. Control chart: Graph used to study how a process changes over time. Comparing current data to historical control limits leads to conclusions about whether the process variation is consistent (in control) or is unpredictable (out of control, affected by special causes of variation).
