Which organization approved the notation for flow charts?

The American National Standards Institute (ANSI) approved the notation for flow charts, making it a recognized authority in standardizing various types of diagrams and representations used in multiple disciplines, including business processes and engineering. ANSI sets the standards that facilitate better communication and consistency in various fields, ensuring that flow charts are universally understood and utilized consistently across different industries.

The flowchart notation standardized by ANSI helps professionals to visualize processes clearly, which enhances process improvement initiatives and communication within organizations. By relying on these standardized symbols and conventions, organizations can create flow charts that are easily interpretable, regardless of their team members' backgrounds.

The other organizations mentioned have their own areas of expertise. The IEEE primarily focuses on electrical and electronic technologies, while ISO develops various international standards across a wide range of industries, and ASQ is dedicated to quality within organizations. However, none of these organizations are specifically credited with the creation and standardization of flowchart notation.
