Industrial Engineering
Experiment
An experiment yields a sample data
◦ For example: Boiling temperature of water.
Data are processed (analyzed, organized,
structured, etc.) to produce information.
Information might then be further
processed to produce knowledge.

“To work out the
structure or form of

making a sketch,
outline, pattern, or
plans” World English

Industrial Engineering
Design
“The approach that engineering (and some other) disciplines use to specify how to create or do something. A successful design must satisfie a (perhaps informal) functional specification (do what it was designed to do); conforms to the limitations of the target medium (it is possible to implement); meets implicit or explicit requirements on performance and resource usage (it is efficient enough). A design may also have to satisfy restrictions on the design process itself, such as its length or cost, or the tools available for doing the design”
Computing Dictionary.

DOE
“Design of Experiments is a formal structured technique for studying any situation that involves a response that varies as a function of one or more independent variables”.

DOE
“DOE is specifically designed to address
complex problems where more than one
variable may affect a response and two
or more variables may interact with each
other”.
