What is the role of a Supplier in the SIPOC model?

In the SIPOC model, suppliers play a fundamental role as they represent both internal and external sources that provide the necessary inputs for a process to function effectively. The SIPOC framework is used to identify all relevant elements of a process in a high-level view, where Suppliers are crucial because they set the foundation for the inputs that drive the process outputs. Without reliable inputs from suppliers, the quality and efficiency of the process could be compromised, impacting the overall results and customer satisfaction.

Understanding this role helps organizations recognize the importance of managing relationships with their suppliers, ensuring that the inputs received meet the required specifications and standards, which ultimately lead to successful process outcomes. The other options do not accurately describe the direct responsibility of suppliers in the context of the SIPOC model.
