"Fundamental tool for determining which characteristic is causing problems in a given process. Constructed by categorizing data, ranking, and plotting frequency of occurrence in bar-chart form in descending order along the x axis. Sometimes dollars are plotted on the y axis to emphasize the cost factor." (Alan Wa Steiss, "Strategic Management for Public and Nonprofit Organizations", 2003)
"A graphical tool for ranking causes from most significant to least significant." (Sohail Anwar, "Quality Management and Control", 2009)
"A chart showing both bars and a line, where the line shows the cumulative total of the individual bars going left to right." (DAMA International, "The DAMA Dictionary of Data Management", 2011)
"A histogram, ordered by frequency of occurrence, that shows how many results were generated by each identified cause." (Cynthia Stackpole, "PMP® Certification All-in-One For Dummies", 2011)
"A method of displaying data values over time and classification" (Daniel Linstedt & W H Inmon, "Data Architecture: A Primer for the Data Scientist", 2014)
"A basic Pareto chart analyzes the unique values of a process variable, which are referred to as Pareto categories or levels. These values typically represent problems encountered during some phase of a manufacturing or service activity." (SAS)
"A Pareto chart is a bar graph. The lengths of the bars represent frequency or cost (time or money), and are arranged with longest bars on the left and the shortest to the right. In this way the chart visually depicts which situations are more significant." (ASQ) [source]
[Pareto analysis] "A statistical technique in decision making that is used for selection of a limited number of factors that produce significant overall effect. In terms of quality improvement, a large majority of problems (80%) are produced by a few key causes (20%)." (IQBBA)
