The '''one-factor-at-a-time method''', (oralso known as '''one-variable-at-a-time''', '''OFAT)''', '''OF@T''',
'''OFaaT''', '''OVAT''', '''OV@T''', '''OVaaT''', or '''monothetic analysis''' is a method of [[design of experiments|designing experiments]] involving the testing of factors, or causes, one at a time instead of allmultiple factors simultaneously. Prominent text books and academic papers currently favor [[factorial design|factorial experimental designs]], a method pioneered by [[Ronald Fisher|Sir Ronald A. Fisher]], where multiple factors are changed at once. The reasons stated for favoring the use of factorial design over OFAT are:

1. OFAT requires more runs for the same precision in effect estimation<br />
