Y = f(X)
Y = f(X) is a common mathematical expression which defines the relationship between the dependent variable 'Y' and the independent variable(s) 'X'. It is read as "Y as a function of X". f denotes the function and it explains the impact of X on Y. In lean six sigma terms, Y is the output metric while X(s) is/are the input metric(s).

Question
Vishwadeep Khatri 265
Q. 130 Y = F(X) indicates that we need to improve inputs and improve the process to get better outputs than what we got earlier. Is it possible to let one of the two remain at a below industry average level (inputs or process) and focus heavily on the other one to generate excellent results? Give examples to explain your answer.
