Process Characterization is a method to identify and quantify the significant source of variation. It is part of the Control phase of DMAIC.
A Box Cox Transformation is a calculation that rearranges the dataset into a normal distribution. The data must be positive and continuous.
Process control for non-normal data involves monitoring and managing industrial or operational processes that produce non-normally distributed data.
Process Capability & Performance (Pp, Ppk, Cp, Cpk) are indicators of the specification relative to process dispersion and process centering.
Evaluating the measurement systems (EMP Studies) is an essential step during the product development phase as impacts the product output.
