Introduction

The flow chart is one of the most important tools for visualizing processes and functions. It is a graphical means of documentation that is mainly used to clearly and simply represent the sequence of actions, operations or events. Its main value lies in the fact that it facilitates communication between individuals, groups or departments, as well as the better understanding of the chronological order that governs a process.

Alternative Names

In the literature, the flow chart is not limited to a single name. It is often referred to as a block diagram, a system diagram, an execution chart, a procedure diagram, a logical diagram or even a repetition diagram. The variety of these names reflects the different uses and adaptations of the tool in various fields of analysis and practical application.

Types of Flow Charts

There are two main types of diagrams used in the analysis and description of processes. The flow chart, in its classic form, provides a detailed view of specific procedures and focuses on the way in which a sequence of actions is executed. In contrast, the system diagram is richer in images and representations and is usually used by analysts who wish to describe a system in greater completeness, including means, equipment and procedures. Despite their differences, both types follow common reading conventions, from top to bottom and from left to right, use geometric shapes and arrows, and aim at the clear and comprehensible representation of data and processes.

Construction of a Flow Chart

The creation of a flow chart is based on the use of specific geometric shapes, each of which indicates an action or function. The process begins with the representation of the starting point through an ellipse shape. Next, questions that have two or more possible answers are depicted inside a diamond, while the operations and actions that are carried out are represented inside rectangles. The end of the process is also indicated with the ellipse shape, thus closing the cycle of the sequence. A decisive factor for the completion of a proper diagram is the connection of all these steps with arrows, which accurately show the order of execution. In this way, it is ensured that any observer can understand the flow of actions without additional explanations.

Flow Chart Programs

Flow charts are not merely simple graphic representations, but are often prepared as complete programs that describe in detail the sequence of operations. In practice, they begin with input data and end with output data, with each intermediate step clearly represented. Such a program helps analysts describe step by step the procedures, reduce clutter through the use of connectors and provide cross-references and positional notes. Moreover, the forms that these programs can take vary, with vertical bars emphasizing the sequence of actions from top to bottom, while horizontal bars highlight the flow of actions from left to right. In addition, analysts may incorporate software elements or register names, thereby enhancing the clarity and accuracy of the diagram.

Conclusion

The flow chart is a powerful and irreplaceable tool that combines the simplicity of graphical representation with the precision of procedural description. It is widely used in fields such as computer science, business management, systems analysis and education, offering the ability to clearly understand and communicate even complex processes. The standardization of shapes and the methodical approach in its design make the flow chart an essential tool for any analyst or professional who wishes to organize and present their work clearly. Through its structure, not only its technical but also its communicative dimension is highlighted, making it an integral part of modern professional practice.
