An Input-Process-Output (IPO) Model (or IPO Diagram) is a visual representation of a process or system showing the key inputs, resulting outputs, necessary controls and essential enablers of a system life cycle that is used to approach in systems analysis and software engineering for describing the structure of an information processing program or other process. The IPO chart describes business processes with the description of each component in word, not code or mathematical formulas.
Reference Definition by Wikipedia: The input–process–output (IPO) model, or input-process-output pattern, is a widely used approach in systems analysis and software engineering for describing the structure of an information processing program or other process. Many introductory programming and systems analysis texts introduce this as the most basic structure for describing a process.
