This answer selects Universal Process Notation (UPN) as the tool that the BA should use for their evaluation of a business process at UC. UPN is a simple and standardized way of creating process maps, using only four symbols: activity, decision, start/end, and annotation. UPN can help the BA evaluate a business process at a high level and in detail, while also keeping regulatory considerations in mind, by showing the steps, actions, decisions, roles, and dependencies of the process, and adding notes or comments to explain or clarify certain aspects.
