In six sigma under the define phase, which of the following is used to find the root of a problem?

The acronym SIPOC stands for Suppliers, Inputs, Process, Outputs and Customer. Using information from these five areas creates a process map that gives a high-level overview of a Six Sigma project. This is called  high-level Process Map  or Bird’s eye view. This tool allows a team to view their process with respect to inputs, outputs, and suppliers. It provides the process scope while showing the process boundaries. Also, it helps in identifying the relationship among the supplier, inputs, and process; and gives visibility to the customers and their requirements.
