Which tool should be used to closely monitor inputs and outputs?

Individual pro forma statements are financial projections that outline expected revenues and expenses for a specific period. While they help in forecasting financial performance, they do not provide a direct visualization of inputs and outputs in a process context, making them less suitable for monitoring operational flows compared to a SIPOC diagram.

Joint financial statements reflect the financial position and performance of multiple entities combined. While useful for understanding overall financial health, they do not focus on the operational inputs and outputs of specific processes, thereby limiting their applicability for monitoring process flows directly.

A business process diagram outlines the sequence of activities in a process and their interconnections. While it can illustrate workflow, it does not explicitly detail the inputs and outputs in the same structured way as a SIPOC diagram, which specifically highlights these components for monitoring purposes.
