Under this school of thought, each flowchart is of a certain level (between 0 and 4) based on the amount of detail the flowchart contains. A level 0 flowchart represents the least amount of detail, and usually contains one or two steps. A level 4 flowchart represents the most detail, and can include hundreds of steps.
The so-called zero level is followed by DFD 0, starting with process numbering (e.g. process 1, process 2). In the next, the so-called first level—DFD 1—the numbering continues For example, process 1 is divided into the first three levels of the DFD, which are numbered 1.1, 1.2, and 1.3.
Version 2.0 of BPMN was released in January 2011, [1] at which point the name was amended to Business Process Model and Notation to reflect the introduction of execution semantics, which were introduced alongside the existing notational and diagramming elements.
Level 0 is the lowest maturity level; Level 5 is the highest maturity level. The maturity levels are named and characterized as follows: Level 0 = "incomplete"; incomplete. Level 1 = "performed"; the process purpose is fulfilled by executing the base practices and generating the output work products.
An example of a Top Level Context Diagram for an information system management process is shown in Figure 3. From this diagram lower-level diagrams are generated. An example of a derived diagram, called a “child” in IDEF0 terminology, for a life cycle function is shown in Figure 4. [1]
Purdue Reference Model, “95” provides a model for enterprise control, which end users, integrators and vendors can share in integrating applications at key [5] layers in the enterprise: Level 0 — The physical process — Defines the actual physical processes. Level 1 — Intelligent devices — Sensing and manipulating the physical ...

Flow diagram a C-style for loop, representing the following code: for(i=0;i<5;i++) printf("*"); The loop will cause five asterisks to be printed. Flowcharts are used to design and document simple processes or programs. Like other types of diagrams, they help visualize the process.
