A process mapping methodology typically used in the define phase of DMAIC is SIPOC. (pronounced SI PAUCK)
Use: The mapping process starts with identifying the customers’ needs and requirements. The team then determines the outputs of the process that have an effect on those requirements. The team lists 5 to 7 high-level steps of the process. They begin to identify the inputs to the process and the suppliers who provide for those inputs. SIPOC is an effective way of seeing the whole value-add process on one graphic. It shows the relationships between inputs and outputs.
S: Suppliers
I: Inputs
P: Process
O: Outputs
C: Customer
