Detailed Process Map Template

Abstract: Detailed process maps are used to identify sources of variation, opportunities for improvement, and help characterize the relationships Y = f(x). They are helpful in identifying the key inputs (X's) and output variables (Y's). Key inputs into the process can be classified as follows: Noise (N) - are inputs that are uncontrollable or too costly to control. Controllable (C) - are inputs that can be changed; they are sometimes called "knob" variables because they can be turned or adjusted. Standard Operating Procedures (S) - are procedures, drawings, or work instructions that do not need to be tested or changed. Critical (X) - are inputs that have a major impact on Y's; usually unknown when first developing the process map.
