The input–process–output model. 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 ...
HIPO model (hierarchical input process output model) is a systems analysis design aid and documentation technique from the 1970s, [1] used for representing the modules of a system as a hierarchy and for documenting each module.
Standard output is a stream to which a program writes its output data. The program requests data transfer with the write operation. Not all programs generate output. For example, the file rename command (variously called mv, move, or ren) is silent on success. Unless redirected, standard output is
Shows a conditional operation that determines which one of the two paths the program will take. [16] The operation is commonly a yes/no question or true/false test. Represented as a diamond . [17] Input/Output [17] Indicates the process of inputting and outputting data, [17] as in entering data or
An input transition refers to a transition (s, π, s') when π is an input action, output transition indicates a transition (s, π, s') when π is an output action and so on. For any state s and action π, if the I/O automaton A has some transition of the form (s, π, s'), then π is said to be enabled in s.
The input–process–output (IPO) model of teams provides a framework for conceptualizing teams. The IPO model suggests that many factors influence a team's productivity and cohesiveness . It "provides a way to understand how teams perform, and how to maximize their performance".

Process. The process (function, transformation) is part of a system that transforms inputs to outputs. The symbol of a process is a circle, an oval, a rectangle or a rectangle with rounded corners (according to the type of notation). The process is named in one word, a short sentence, or a phrase that is clearly to express its essence. [7] Data ...
