Who approved the notation used for the flow chart?

The American National Standards Institute (ANSI) is responsible for the approval of various standards, including the notation used in flow charts. ANSI establishes guidelines and standards to ensure consistency across various industries and disciplines in the United States, which includes the development and endorsement of graphical symbols and notations that are widely recognized and used for flow charting.

Flow charts rely on standardized symbols to clearly convey processes and decisions, enabling effective communication and understanding among stakeholders. ANSI's role in approving these standards helps ensure that anyone using flow charts can interpret them correctly, regardless of their background or the industry they are in. This endorsement by ANSI reflects its commitment to promoting best practices and operational excellence through standardized methodologies.

The other organizations listed, while influential in their respective areas, focus on different aspects of standardization and may not specifically address flow chart notation approval. For example, ISO is known for international standards across a wide array of subjects, IEEE focuses on electrical and electronic standards and technologies, and FSO is less commonly associated with flowchart notation. Thus, ANSI is the correct answer for this question regarding flow chart standardization.
