The start/end symbol is represented by a rounded rectangle and indicates the beginning or end of a process. It signifies the starting point of the logic flow diagram and also marks the final step or result. This symbol is essential for defining the scope and boundaries of the process being depicted.
The Process Symbol
The process symbol, represented by a rectangle, represents an action or task within the logic flow. It signifies an operation that needs to be performed to move forward in the process. These actions can involve calculations, data manipulation, or other types of operations depending on the specific context of the diagram.
The Decision Symbol
The decision symbol, represented by a diamond shape, is used to depict a branching point in the logic flow. It represents a decision that needs to be made based on a certain condition or criterion. The flow can diverge into multiple paths depending on the outcome of the decision, allowing for different actions or processes to be followed.
The Input/Output Symbol
The input/output symbol, represented by a parallelogram, indicates the process of entering or retrieving data from an external source. It represents the interaction between the system being analyzed and the external environment. This symbol is crucial for understanding how data is being utilized or produced within the logic flow.
The Connector Symbol
The connector symbol, represented by a small circle, is used to connect different parts of the logic flow diagram. It ensures that the flow remains organized and coherent, allowing for a clear representation of the sequence of steps. Connectors are particularly useful when a process requires multiple actions or decisions to be taken.
The Off-Page Connector Symbol
The off-page connector symbol, represented by a rectangle with wavy lines, is used when a process continues on a separate page. It indicates that the logic flow diagram extends beyond the current page and provides a reference point for the continuation of the process. This symbol helps maintain clarity and prevents overcrowding of information on a single page.
The Annotation Symbol
The annotation symbol, represented by a small rectangle with a dashed line, is used to provide additional information or comments about a specific part of the logic flow diagram. It allows for the inclusion of explanatory notes or descriptions that may assist in understanding the process or decision being depicted. Annotations contribute to the overall clarity and readability of the diagram.
The Delay Symbol
The delay symbol, represented by an elongated hexagon, indicates a pause or waiting period within the logic flow. It represents a temporary halt in the process where no action is being performed. This symbol is particularly useful when there is a need to account for time delays or dependencies between different steps.
The Loop Symbol
The loop symbol, represented by a curved arrow, signifies a repetitive sequence of steps within the logic flow. It indicates that a specific set of actions or decisions needs to be repeated until a certain condition is met. This symbol helps streamline the representation of complex processes that involve iterations or loops.
Conclusion
Logic flow diagrams are powerful tools for analyzing and understanding complex systems. By familiarizing oneself with the symbols commonly used in these diagrams, professionals can effectively communicate processes, make informed decisions, and identify potential areas for improvement.

The use of rectangles in a flow chart ensures clarity and organization by breaking down complex processes into manageable steps.Diamond
The diamond symbol signifies a decision point in the flow chart. It represents a condition or a question that needs to be answered before determining the subsequent steps in the process. The diamond acts as a branching point, where the flow of the process can diverge based on different conditions. The decision made at the diamond symbol determines which path the process should follow, leading to different outcomes or actions.Circle
The circle symbol represents a start or end point in the flow chart. It indicates the beginning or completion of a process or activity. The circle acts as a marker for the initiation or termination of a particular process. When placed at the beginning, it denotes the starting point of the process, while when placed at the end, it represents the conclusion or accomplishment of the process. The use of circles in a flow chart helps in identifying the boundaries of the process.Arrow
The arrow symbol plays a crucial role in connecting the different symbols in the logic flow diagram. It indicates the sequence of steps or tasks to be followed. The arrow visually represents the flow of the process, showing the direction in which the process moves from one symbol to another. By linking the symbols with arrows, the flow chart illustrates the logical order in which the actions need to be executed.Parallelogram
The parallelogram symbol in a flow chart indicates an input or output from the system. It represents the information or data that is required or produced during a specific step or process. The parallelogram serves as a connector between the system and its external environment. It highlights the interaction between the process and its inputs or outputs, emphasizing the importance of data flow in the overall system.Oval
The oval symbol in a flow chart represents a connector or merge point. It is used to join multiple paths or branches in the logic flow diagram. The oval acts as a junction where different paths converge or diverge. It enables the flow chart to handle complex processes with multiple decision points and alternative paths. The use of ovals enhances the flexibility and comprehensibility of the flow chart by accommodating various possibilities within the process.Dashed Arrow
The dashed arrow symbol shows a conditional flow or optional sequence in the flow chart. It represents an alternative path that may be followed based on a specific condition or decision. The dashed arrow allows the flow chart to incorporate different scenarios or exceptions within the process. It ensures that the flow chart is not limited to a single linear sequence, but can adapt to varying conditions or choices.Double Rectangle
The double rectangle symbol denotes a sub-process or sub-routine within the main process. It represents a separate set of steps or activities that are performed as part of the larger process. The double rectangle helps in organizing and modularizing complex processes by breaking them down into smaller, manageable components. It allows for a more detailed representation of the process flow and supports better understanding and analysis of the overall system.Rounded Rectangle
The rounded rectangle symbol indicates a document or report in the flow chart. It represents a specific document or information that is generated or required during the process. The rounded rectangle emphasizes the importance of documentation and communication within the system. It highlights the need for formal records and reports to ensure proper tracking and accountability throughout the process.Straight Arrow
The straight arrow symbol represents a normal flow or sequence in the logic flow diagram. It indicates a direct and straightforward path without any deviations or alternatives. The straight arrow connects symbols in a linear manner, signifying a clear and uninterrupted progression of the process. The use of straight arrows simplifies the flow chart by eliminating complex decision points and focusing on the primary sequence of actions.Conclusion
