Which organization approved the notation for flowcharts?

The American National Standards Institute (ANSI) is the organization responsible for approving the notation for flowcharts. ANSI developed standardized symbols and guidelines for creating flowcharts to ensure clarity and consistency in depicting processes. This standardization facilitates effective communication, making it easier for professionals across different industries to understand and analyze workflows.

Flowcharts serve as a visual representation of processes, and having a recognized set of symbols helps eliminate confusion and misinterpretation. ANSI's standards for flowchart symbols include various shapes such as ovals for start and end points, rectangles for processes, diamonds for decisions, and arrows for direction of flow, all of which are crucial for accurately conveying the relationships and sequences in business processes.

While other organizations like ISO and PMI are involved in various standardization efforts across different areas, they do not specifically govern the standardized notation of flowcharts. The Object Management Group focuses primarily on standards related to object-oriented programming and modeling techniques rather than flowchart notation.
