"Graphical notation.
IDEF0 is a model that consists of a hierarchical series of diagrams, text, and glossary cross referenced to each other. The two primary modeling components are:
- functions (represented on a diagram by boxes), and
- data and objects that interrelate those functions (represented by arrows).
.... the position at which the arrow attaches to a box conveys the specific role of the interface. The controls enter the top of the box. The inputs, the data or objects acted upon by the operation, enter the box from the left. The outputs of the operation leave the right-hand side of the box. Mechanism arrows that provide supporting means for performing the function join (point up to) the bottom of the box." [IDEF0. Wikipedia]
The example "IDEF0 diagram - Inter-box connections" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the solution "IDEF Business Process Diagrams" from the area "Business Processes" of ConceptDraw Solution Park.

The IDEF0 process.
The IDEF0 process starts with the identification of the prime function to be decomposed. This function is identified on a “Top Level Context Diagram,” that defines the scope of the particular IDEF0 analysis. ... From this diagram lower-level diagrams are generated." [IDEF0. Wikipedia]

This interactive voice response (IVR) diagram sample shows the Scheme of VoIP call with SIM box and gateway. It was designed on the base of the Wikimedia Commons file: Scheme of VoIP call with Sim box.png. [commons.wikimedia.org/ wiki/ File:Scheme_ of_ VoIP_ call_ with_ Sim_ box.png]

"A SIM box (also called a SIM bank) is device used as part of a VoIP gateway installation. It contains a number of SIM cards, which are linked to the gateway but housed and stored separately from it. A SIM box can have SIM cards of different mobile operators installed, permitting it to operate with several GSM gateways located in different places." [SIM box. Wikipedia]

This Eisenhower decision matrix example was designed on the base of Wikimedia Commons file: MerrillCoveyMatrix.png. [commons.wikimedia.org/ wiki/ File:MerrillCoveyMatrix.png]
"Using the Eisenhower Decision Principle, tasks are evaluated using the criteria important / unimportant and urgent/ not urgent, and then placed in according quadrants in an Eisenhower Matrix (also known as an "Eisenhower Box" or "Eisenhower Decision Matrix"). Tasks are then handled as follows:
Tasks in
1. Important / Urgent quadrant are done immediately and personally e.g. crises, deadlines, problems.
2. Important / Not Urgent quadrant get an end date and are done personally e.g. relationships, planning, recreation.
3. Unimportant / Urgent quadrant are delegated e.g. interruptions, meetings, activities.
4. Unimportant / Not Urgent quadrant are dropped e.g. time wasters, pleasant activities, trivia." [The Eisenhower Method. Time management. Wikipedia]
The matrix diagram sample "Eisenhower box" was created using the ConceptDraw PRO software extended with the Scrum solution from the Project Management area of ConceptDraw Solution Park.

The vector stencils library "IDEF0 diagrams" contains 18 symbols for drawing IDEF0 function modeling diagrams using the ConceptDraw PRO diagramming and vector drawing software.
"The IDEF0 model ... is based on a simple syntax. Each activity is described by a verb-based label placed in a box. Inputs are shown as arrows entering the left side of the activity box while output are shown as exiting arrows on the right side of the box. Controls are displayed as arrows entering the top of the box and mechanisms are displayed as arrows entering from the bottom of the box. Inputs, Controls, Outputs, and Mechanisms are all referred to as concepts.
- Arrow : A directed line, composed of one or more arrow segments, that models an open channel or conduit conveying data or objects from source (no arrowhead) to use (with arrowhead). There are 4 arrow classes: Input Arrow, Output Arrow, Control Arrow, and Mechanism Arrow (includes Call Arrow). See Arrow Segment, Boundary Arrow, Internal Arrow.
- Box : A rectangle, containing a name and number, used to represent a function.
- Context : The immediate environment in which a function (or set of functions on a diagram) operates.
- Decomposition : The partitioning of a modeled function into its component functions.
- Fork : The junction at which an IDEF0 arrow segment (going from source to use) divides into two or more arrow segments. May denote unbundling of meaning.
- Function : An activity, process, or transformation (modeled by an IDEF0 box) identified by a verb or verb phrase that describes what must be accomplished.
- Join : The junction at which an IDEF0 arrow segment (going from source to use) merges with one or more other arrow segments to form a single arrow segment. May denote bundling of arrow segment meanings.
- Node : A box from which child boxes originate; a parent box. See Node Index, Node Tree, Node Number, Node Reference, Diagram Node Number." [IDEF0. Wikipedia]

This onion diagram example was designed on the base of figure "Academic advising stakeholder framework" in the article "Defining Advising Stakeholder Groups" by Julianne Messia from the website of NACADA Executive Office,
Kansas State University.
"A complete stakeholder analysis, therefore, not only names the stakeholders but accurately characterizes each stakeholder’s power and influence.
Harney (2008) identified advising stakeholders as being either internal or external constituents. Stakeholders belong in one of three distinct classifications: (1) internal core stakeholders, (2) internal but indirect stakeholders, and (3) external and indirect stakeholders. The chart below (Figure 1) depicts these groups in a diagram representing their various levels of input, influence, and involvement; the closer a group is to the “core” the more investment and weight that group has in advising. The groups utilized in this specific example assume a shared model of advising (both faculty and advising professionals have advising responsibilities). As each institution has its own unique culture and advising model, the chart should be adapted for any program or institution. For instance, an institution with a centralized advising model may list faculty as Internal but Indirect Stakeholders as they do not provide or administer advising directly."
