Control Charts track analytical performance
Control charting is a way to visually track performance to determine when a procedure is not meeting data-quality objectives. Analysts can identify procedural problems by using control charts. When problems are indicated, the analyst can pause to find solutions, eliminate the source of the problem, and prevent the out-of-control situation. Spreadsheet files automate the construction and use of these charts.
