# Venn Diagram

Venn Diagrams are illustrations used in the branch of mathematics known as set theory. They show the mathematical or logical relationship between different groups of things (sets). A
The combined area of sets in a Venn Diagram is called the union of sets. Sometimes there is a rectangle around the Venn diagram to show the space of all possible elements. This rectangle represents so-called Universal set. A Venn Diagram is usually used to divide up two or more objects to highlight similarities and differences. Venn Diagrams visualize all the possible logical relations between sets. They are used to illustrate simple set relationships in logic, statistics, mathematics, sociology, philosophy, marketing, etc. Venn Diagrams are also commonly used to visually summarize the status and future viability of a project. |

**Example 3.** Venn Diagram - Sustainable Development

There are some similar diagram types, based on Venn Diagram:

- Euler diagrams similar to Venn Diagrams, but they may not describe all the possible relations.
- Johnston diagrams, which are used to illustrate statements in propositional logic, such as "Neither A nor B is true", and are a visual way of illustrating truth tables.
- Karnaugh maps or Veitch diagram are another way of visually representing Boolean expressions.
- Peirce diagrams, devised by Charles Peirce, are extensions to Venn diagrams which include information on existential statements, disjunctive information, probabilities, and relations.

**Example 3.** Venn Diagram - Knowledge

This simple example was created in ConceptDraw PRO using the Venn Diagrams Solution. It shows the use of Venn Diagram to compare two people groups. One circle represents all the information people know about the stock market in Britain, the other circle represents all the information they know about stock market in Germany. Any features the two areas share can be written in the intersection of the circles. The result shows at a glance what the two markets have in common and what features are different.

Use Venn Diagrams solution to quick and easy design your own Venn Diagram of any complexity.

The Venn Diagrams designed with ConceptDraw PRO are vector graphic documents and are available for reviewing, modifying, converting to a variety of formats (image, HTML, PDF file, MS PowerPoint Presentation, Adobe Flash or MS Visio), printing and send via e-mail in one moment.

One of the three main constituents of any enterprise is the Control and Information Architecture. The rest two are Production facilities and People and Organization.### Organogram Software

Organizing process is the process of creating the organizational structure of an enterprise. The organizing process consists of several stages. First, you need to divide the organization into departments, respectively to strategies, and then establish relationships of authority. After that, managing director delegates his rights and authorities.### 2 Circle Venn Diagram. Venn Diagram Example

While creating flowcharts and process flow diagrams, you should use special objects to define different statements, so anyone aware of flowcharts can get your scheme right. There is a short and an extended list of basic flowchart symbols and their meaning. Basic flowchart symbols include terminator objects, rectangles for describing steps of a process, diamonds representing appearing conditions and questions and parallelograms to show incoming data. This diagram gives a general review of the standard symbols that are used when creating flowcharts and process flow diagrams. The practice of using a set of standard flowchart symbols was admitted in order to make flowcharts and other process flow diagrams created by any person properly understandable by other people. The flowchart symbols depict different kinds of actions and phases in a process. The sequence of the actions, and the relationships between them are shown by special lines and arrows. There are a large number of flowchart symbols. Which of them can be used in the particular diagram depends on its type. For instance, some symbols used in data flow diagrams usually are not used in the process flowcharts. Business process system use exactly these flowchart symbols.### Cross-Functional Flowchart

There are many tools to manage a process or to illustrate an algorithm or a workflow. Flowcharting is one of those tools. However, it may be difficult to show complex processes that require multiple attributes or several people in a simple flowchart, so a cross-functional flowchart would be a solution for that situation. To create such flowchart, group processes and steps to labeled rows or columns, and divide those groups with horizontal or vertical parallel lines. It is worth mentioning that there are different types of cross-functional flowcharts, like opportunity or deployment flowchart. This diagram shows a cross-functional flowchart that was made for a trading process. It contains 14 processes, distributed through 5 lines depicting the participants who interact with the process. Also there are connectors that show the data flow of information between processes. The cross-functional flowchart displays a detailed model of the trading process, as well as all participants in the process and how they interact with each other. The lines in the flowchart indicates the position, department and role of the trading process participants.### UML Class Diagram Generalization ExampleUML Diagrams
