Control
Chart
The cornerstone of Statistical Process Control, the Control Chart
highlights special causes of variation in a repeating process. They are
not the easiest of tools to use and a degree of statistical knowledge is
of significant benefit. Generally, they are only useful in high frequency processes
where there is sufficient data, although short-run charts can be used.
The Control Chart is one of the first seven tools.
Note: The Control Chart in practice is quite complex, with a
number different types of chart and calculation depending on the data
being analysed. This summary is thus a significant simplification!
