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

Individual pro forma statements are financial documents that project future income and expenses based on certain assumptions. While they can be useful for forecasting, they do not provide a direct view of the operational inputs and outputs within a process, making them less suitable for monitoring process flows.

While a business process diagram can illustrate the steps in a process, it is generally more focused on the workflow and sequence of activities rather than specifically highlighting inputs and outputs. It may not effectively capture all relevant elements needed for close monitoring compared to a SIPOC diagram.

Joint financial statements combine the financial results of two or more entities and focus on overall financial performance rather than operational processes. They do not provide detailed insights into the inputs and outputs of specific processes, making them irrelevant for closely monitoring those elements.
