Black Belts are individuals that are trained in the application of Six Sigma philosophy. Black Belts typically receive 160 hours of training and work full-time on projects. They are change agents, and by working with the employees, will increase knowledge through the acquisition of data. Working together will make this philosophy part of the company culture in all aspects of the business. II-56 6

Y = f(x) Y is the dependent output variable of a process. It is used to monitor a process to see if it is out of control, or if symptoms are developing within a process. It is a function of the Xs that contribute to the process. Once quantified through Design of Experiment, a transfer function Y=f(X) can be developed to define the relationship of elements and help control a process. Y is the output measure, such as process cycle time or customer satisfaction. f(x) is the transfer function, which explains the transformation of the inputs into the output. x is any process input process step that is involved in producing the output.
