ABSTRACT
A Suppliers, inputs, process, outputs and customers (SIPOC) diagram is a tool every internal audit team should consider using to identify the relevant elements of a process before fieldwork begins. SIPOC is an acronym that stands for suppliers, inputs, process, outputs, and customers. The SIPOC Diagram is particularly useful when defining the scope of the review because it can give internal auditors a high-level overview of the process. SIPOC Diagrams can also help perform a stakeholder analysis, so the key participants in the process are identified. The SIPOC Diagram is a very simple yet very useful and powerful tool. The time spent preparing it will greatly enhance the value obtained from every internal audit. Good outcomes are the result of effective planning, and SIPOC Diagrams are a great tool to help in that regard. SIPOC Diagrams can help internal auditors plan their engagements more effectively. They capture the list of Suppliers, Inputs, the Process, Outputs, and Customers.
