Design of experiments and analysis of data from designed experiments are well-established
methodologies in which statisticians are formally trained. Another critical and rarely taught
skill is the planning that precedes designing an experiment. This article suggests a set of tools
for presenting generic technical issues and experimental features found in industrial experi-
ments. These tools are predesign experiment guide sheets to systematize the planning process
and to produce organized written documentation. They also help experimenters discuss com-
plex trade-offs between practical limitations and statistical preferences in the experiment. A
case study involving the (computer numerical control) CNC-machining of jet engine impellers
is included.
