Which component is NOT included in Inputs of an IPO diagram?

In an Input-Process-Output (IPO) diagram, the focus is on categorizing system components into inputs, processes, and outputs. Inputs refer to all elements needed to drive the process, while outputs are the results generated from that process.

The component that is not included in the inputs of an IPO diagram is process results. Process results represent the outputs derived after the processing phase has been completed. They are the end products or outcomes of the inputs that have been transformed by a process. Input components, on the other hand, are what you start with before any processing occurs. This delineation is essential in systems engineering for a clear understanding of how a system functions and how different components interrelate.

In contrast, user feedback, data inputs, and operational parameters all serve as vital elements that feed into the process, making them integral to the input category of the IPO framework. Their roles are to provide essential information, constraints, and requirements that guide the processing phase. Understanding the distinction of what constitutes an input versus an output is crucial when analyzing or designing systems.
