A structured approach to planning, running, and analyzing data from a sequence of tests A strategy for experimentation which uses planning and structure to maximize efficiency Systematically varies the selected levels of input variables in an organized, structured way, so that we can more easily identify the reasons for changes observed in the output Control the Inputs, and the Outputs will Follow Why use Experimental Design? Planning Questions to be answered by a team are established in advance Data collection sheets procedures are prepared in advance Factor levels are decided upon in advance The data analysis method is decided upon in advance Limitations of the data analysis are known in advance Structure Process parameters are intentionally adjusted to predetermined levels, according to a predetermined plan, in order to Determine which factors and/or interactions have the greatest effect on the response Determine the optimum settings for those factors deemed to be important Efficiency Properly designed experiments offer the maximum amount of information for the minimum amount of experimentation DOE Benefits and Uses To maximize the information content of the data To ensure that the questions that need to be answered can be answered To allocate eff
