The Pareto Plot Platform
A Pareto plot is a statistical quality improvement tool that shows frequency, relative frequency, and cumulative frequency of problems in a process or operation. It is a bar chart that displays severity (frequency) of problems in a quality-related process or operation. The bars are ordered by frequency in decreasing order from left to right, which makes a Pareto plot useful for deciding what problems should be solved first.
