The step that the BA should include in the business flowchart is to capture decision steps and different outcomes. Decision steps are points in the process where a choice or condition needs to be evaluated, and different outcomes are possible depending on the result of the evaluation. Capturing decision steps and different outcomes helps to show the logic and flow of the process, and account for different scenarios or exceptions that may occur. The other options are either irrelevant or incomplete. Option B does not relate to the business flowchart, but rather to the data model or integration design. Option C does not specify what limits to set or how to document them. References:
