What is required to ensure effective documentation of a flow’s purpose?

Using named variables that clearly reflect the flow’s operation is essential for effective documentation of a flow’s purpose. When variables are named in a way that aligns with their function, they enhance the clarity and understanding of the flow's logic. This practice allows anyone reviewing the flow—be it the original creator or another team member—to easily comprehend what each component is intended to do, thus improving maintainability and collaboration.

Clear variable names serve as a form of self-documenting code, making it easier to track the flow's actions and the relationships between data elements. This clarity is crucial in environments where multiple users may interact with or modify the flow over time.

Other options, while they might contribute to documentation in different ways, do not provide the same direct clarity regarding the flow's purpose. Technical jargon can obscure understanding, user manuals require additional effort and maintenance, and color coding, though helpful for visual organization, does not provide context about the specifics of the flow's operations.
