Each attribute has now been assigned a number for importance that becomes the basis for a Pareto diagram showing how the supplier should focus the offering (FIGURE 1).
A Pareto diagram shows the relative influence of a small number of factors that affect the quality of a product or service.
Figure 1 shows the Pareto diagram to sort the factors according to their influence on the mean of surface roughness values.
Tools used to accomplish this may include control charts, appropriate statistical analyses, and/or Pareto diagrams.

It contains charting tools such as Pareto diagrams, scattergrams, and histograms.
In addition, one of the appendices reviews the tools of TQM, such as flow charts and Pareto diagrams, while another details the experiences of three specific health care organizations involved in the project.
Examinator's intuitive graphic interface lets engineers generate comprehensive reports, such as yield summary, Cp, Cpk, histograms, wafer maps, Pareto diagrams, and gage R&R, without special training or systems integration - allowing engineers to focus their attention on resolving yield and correlation issues.
