In a standard process mapping document, a diamond shape typically represents which of the following?

Comprehensive and Detailed Step-by-Step Explanation:

Diamond Shape: In process mapping, a diamond typically represents a decision point where a choice

must be made based on conditions or criteria (e.g., "Yes" or "No").

Example: "Is the invoice valid?" If yes, the process continues to payment; if no, it is rejected.

Reference: IIA Practice Guide on Process Mapping emphasizes standard symbols such as diamonds

for decisions, rectangles for processes, and arrows for flow lines.

Other Options:

Option A: A process or operation is typically represented by a rectangle.

Option C: A flow line (arrow) indicates the direction of process flow, not a decision.

Thus, the correct answer is B. Decision.
