Unlocking Flowchart Symbols: Your Ultimate Guide

Introduction to Flowchart Symbols

Flowcharts are a powerful tool used to visualize, analyze, and improve business processes. They help companies identify inefficiencies, reduce waste, and optimize workflows. According to a study, companies that use flowcharts and process mapping techniques experience a 20-30% reduction in costs and a 10-20% increase in productivity.

At the heart of every flowchart are its symbols. These symbols represent different elements of a process, such as actions, decisions, and inputs. Understanding the meanings of these symbols is crucial for creating effective flowcharts and communicating with stakeholders. In this article, we will delve into the world of flowchart symbols, exploring their meanings, uses, and best practices.

The History of Flowchart Symbols

Flowchart symbols have a rich history dating back to the 1920s. The first flowcharts were developed by industrial engineer Frank Gilbreth, who used them to analyze and optimize manufacturing processes. Over the years, the symbols and notations used in flowcharts have evolved, with different standards and conventions emerging.

The Importance of Standardization

Standardization is critical when it comes to flowchart symbols. Using standardized symbols ensures that flowcharts are easily understood by all stakeholders, regardless of their background or expertise. In 1970, the American National Standards Institute (ANSI) established a standard for flowchart symbols, which has since been widely adopted.

Common Flowchart Symbols and Their Meanings

Here are some of the most common flowchart symbols, their meanings, and uses:

Shapes and Symbols

  • Oval: Used to represent the start or end of a process.
  • Rectangle: Represents a process or action.
  • Diamond: Used for decision points, where a choice must be made.
  • Arrow: Indicates the flow of the process.
  • Parallelogram: Represents input or output.

Action Symbols

  • Rectangle with a vertical line: Indicates a manual operation.
  • Rectangle with a curved line: Represents a machine operation.
  • Circle with a line: Used for inspection or testing.

Decision Symbols

  • Diamond with a question mark: Represents a decision point with a question.
  • Diamond with a tick: Indicates a decision point with a positive outcome.
  • Diamond with a cross: Represents a decision point with a negative outcome.

Connector Symbols

  • Arrow with a flat head: Indicates a conditional flow.
  • Arrow with a pointed head: Represents an unconditional flow.
  • Dashed line: Used for a flow that is not part of the main process.

Best Practices for Using Flowchart Symbols

When creating flowcharts, it's essential to follow best practices to ensure clarity and effectiveness:

Use Standardized Symbols

Using standardized symbols ensures that your flowchart is easily understood by all stakeholders. Stick to the ANSI standard for flowchart symbols.

Keep it Simple
