Mainly for Development but also for Validation, it may be necessary to perform some production tests to collect useful data for the choice of the best operating conditions. To minimize costs and collect quality information, experiments must be carefully designed according to patterns precise to which to associate the appropriate data processing.
Design of Experiments (DOE) is a set of techniques that aim to choose the best set of tests to perform.
Example:
Corrective Action and Preventive Action -CAPA- for consistent improvement
