Input-process-output approach

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.^[1][2][3][4]

Overview

A computer program is useful for another sort of process using the input-process-output model receives inputs from a user or other source, does some computations on the inputs, and returns the results of the computations.^[1] In essence the system separates itself from the environment, thus defining both inputs and outputs as one united mechanism.^[5] The system would divide the work into three categories:

• A requirement from the environment (input)
• A computation based on the requirement (process)
• A provision for the environment (output)

In other words, such inputs may be materials, human reso
