Flowcharts use various shapes to signify different types of actions or steps in a process. Here are the common ones:
- Oval: This shape usually represents the start or end of a process.
- Rectangle: This is used to show an action or operation. It represents a step in the process where something is done.
- Diamond: This shape is used to represent a decision point. Typically, it contains a yes/no question or true/false test. From the diamond, there are usually two paths (yes and no) that lead to different rectangles (actions or operations).
- Parallelogram: This is used to represent inputs or outputs. It signifies that information is being entered into the system or result/output is being produced.
- Arrow: Arrows are used to guide the viewer through the process, showing the flow from one step to the next.
- Circle or Ellipse: Often used to represent a connector in a flowchart, showing that the flow continues elsewhere on the chart. This is often used in complex flowcharts.
- Rectangle with Double Stripes (Subroutine): This represents a predefined process or operation, often known as a subroutine or a function that is already defined elsewhere.
- Comment or Annotation: It's a bracket or a note for adding additional comments about the process for clarification.
Remember, these are typical uses and could vary depending on specific rules of a given organization or industry. The key is to ensure consistency and clarity in whatever system you use, and to provide a legend or key if the chart might be seen by others who aren't familiar with your symbols.
