Input-process-output (I-P-O) is a structured methodology for capturing and visualizing all of the inputs, outputs, and process steps that are required to transform inputs into outputs.

Each flow chart is concerned with one particular process or system. It begins with the input of data or materials into the system and traces all the procedures needed to convert the input into its ...

All systems can be understood using an input-process-output (IPO) model, and the system we call “innovation” is no exception. This model is likely familiar to you from information technology ...

Mechanical devices can change one form of force to another. All moving parts work on some sort of mechanism. Mechanical systems all involve an input, a process, and an output.

Process devices take the signal from the input stage of a system and act on it by changing it in some way. Transistors are an example of a processing device, and are a special type of switch.
