2. The History of Flowcharts: From Industrial Engineering to Computing

The use of flowcharts to document business processes dates back to the 1920s and 1930s. Industrial engineers Frank and Lillian Gilbreth introduced the “Flow Process Chart” in 1921. Allan H. Morgensen later used these tools to improve work efficiency. In the 1940s, Art Spinanger and Ben S. Graham further popularized flowcharts, adapting them for information processing. Herman Goldstine and John Van Neumann applied flowcharts to computer programming. Today, while pseudocode is also used, flowcharts remain a fundamental tool in software development and process optimization.

3. Common Flowchart Symbols and Their Meanings

Flowcharts use a standardized set of symbols to represent different types of steps and actions. Understanding these symbols is crucial for interpreting and creating flowcharts effectively. Here are some of the most common flowchart symbols:

Symbol Name	Symbol	Description
Terminal/Terminator		Represents the start or end of a process.
Process		Represents a step or action in the process.
Decision		Represents a point where a decision needs to be made.
