A control chart is a tool that monitors quality characteristics of a
process to ensure that process control is being maintained when
monitoring multiple characteristics that are correlated, it is
imperative to use multivariate control chart. Hotelling’s
quality control chart is used to determine
whether or not the process mean vector for two or more variables is
in-control. It is allowing us to simultaneously monitor whether two or
more related variables are in control, and it is shown that
multivariate quality control chart do not indicate which variables
cause the out-of control signal so that the interpretation of the
out-of-control signal. Also, in this paper develops the multivariate
quality control charts of the out of-control signal, this will be
maintained by making and industrial application on the fertilizers
factory. It is important to know that this factory has a special
department for quality control, in order to maintain International
Standardization Organization (ISO).
