ISO/TR 29901:2007通过举例说明了指定、使用和分析四因素全因子设计所需的步骤，以及该方法的五种不同应用。 根据应用的不同，实验中可能会考虑四个因素以外的其他因素。

ISO/TR 29901:2007 describes the steps necessary to specify, to use and to analyse full factorial designs with four factors through illustration, with five distinct applications of this methodology. Depending on the application, a different number of factors other than four may be considered in the experiment.
