Flowcharts typically use the following main symbols: A process step, usually called an activity, is denoted by a rectangular box. A decision is usually denoted by a diamond. A flowchart is described as "cross-functional" when the chart is divided into different vertical or horizontal parts, to describe the control of different organizational units.
Flowchart is a primary type of business process mapping. It consists of some symbols such as arrows, circles, diamonds, boxes, ovals, or rectangles. The type of Flowchart just described is sometimes referred to as a "detailed" flowchart because it includes in detail, the inputs, activities, decision points, and outputs of any process.
A PFD can be computer generated from process simulators (see List of Chemical Process Simulators), CAD packages, or flow chart software using a library of chemical engineering symbols. Rules and symbols are available from standardization organizations such as DIN, ISO or ANSI. Often PFDs are produced on large sheets of paper.
The term flow diagram is used in theory and practice in different meanings. Most commonly the flow chart and flow diagram are used in an interchangeable way in the meaning of a representation of a process. For example the Information Graphics: A Comprehensive Illustrated Reference by Harris (1999) gives two separate definitions:
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 flow
