To document the current state business process for implementing Salesforce Financial Services Cloud, the consultant should create an end-to-end visual map of the process using personas, systems, inputs, and outcomes. A visual map is a tool that can help illustrate the flow of a business process from start to finish, showing the steps, decisions, and dependencies involved in each stage. A visual map can also include personas, systems, inputs, and outcomes to provide more context and detail for each step of the process. Personas are fictional characters that represent the different roles or users that participate in or interact with the process. Systems are the tools or applications that are used to perform or support the process. Inputs are the data or information that are required or provided for each step of the process. Outcomes are the results or outputs that are achieved or delivered by each step of the process. Verified Reference: : Salesforce Help Article 3 : Salesforce Help Article [4]
