Which sequence correctly represents the standard SIPOC order?

Which sequence correctly represents the standard SIPOC order?

• A. Suppliers, Inputs, Process, Outputs, Customers
• B. Customers, Outputs, Process, Inputs, Suppliers
• C. Process, Inputs, Suppliers, Customers, Outputs
• D. Outputs, Customers, Process, Inputs, Suppliers

Answer: (A)

SIPOC is about showing how resources flow into and out of a process, from who provides them to who uses the results. The standard order captures that upstream-to-downstream flow: suppliers supply the inputs, the process transforms those inputs, outputs are produced, and those outputs are delivered to customers. That makes the sequence Suppliers, Inputs, Process, Outputs, Customers the best representation because it mirrors how value actually moves through the system. Other sequences disrupt this logical flow. Starting with customers places the end recipients at the beginning without establishing what resources or inputs enable the work. Putting outputs before the process suggests a result exists before it’s created. Reversing the order of inputs and suppliers or placing suppliers after the process breaks the cause-and-effect chain that SIPOC is meant to delineate. This ordering helps teams clearly define who provides what, what is needed, what the process does, what is produced, and who receives it, which is essential for effective process mapping and improvement.
