2. Suppliers, Inputs, Products, Outputs, Clients

3. Services, Inputs, Processes, Outputs, Customers

4. Systems, Inputs, Processes, Outcomes, Customers

The correct answer is: Suppliers, Inputs, Processes, Outputs, Customers

The acronym SIPOC stands for Suppliers, Inputs, Processes, Outputs, and Customers, which is a widely used tool in process improvement methodologies like Six Sigma. This framework provides a high-level overview of a process and helps teams understand the key components involved in delivering a product or service. By identifying suppliers, the focus is placed on who provides the inputs necessary for the process. Inputs are the resources, materials, or information required to carry out the processes. The Processes section outlines the steps or activities involved in transforming those inputs into outputs. Outputs refer to the products, services, or results produced by the process that are delivered to customers. Finally, Customers represent the stakeholders or end-users who receive the outputs and benefit from the process. Using the SIPOC tool allows organizations to clarify the scope of a process, align team members on expectations, and identify areas for improvement, making it essential for effective process analysis and optimization.
