    Cause and Effect Diagram is a decomposition technique that helps trace an undesirable effect back to its root cause. On the other hand, Histograms can show the number of defects per deliverable or other representations of project or product defects.Scatter diagrams can demonstrate a relationship between any element of a process, environment, or activity on one axis and a quality defect on the other axis.
