Which shape typically represents a process in a flow chart?

In a flow chart, the rectangle is the standard shape used to represent a process or an operation. This shape signifies steps in a workflow, indicating actions such as tasks or operations that need to be performed. The rectangular shape provides a clear and straightforward visual indication of a procedural step, making it easy for anyone reviewing the chart to understand what actions are being carried out.

Other shapes in flow charts serve different purposes; for instance, diamonds typically represent decision points, where a choice is made that affects the flow of the process. Parallelograms are used to show inputs and outputs, such as data entry or results. Oblongs, while sometimes used in different contexts, are not standard for indicating processes. The rectangle's established use in process representation makes it the most appropriate choice in this scenario.
