The best tool for identifying the key recruitment steps and stakeholders in a visual format is to map the business process. Business process mapping is a technique that helps to create a visual representation of a business process. It shows the steps, inputs, outputs, roles, and decisions involved in the process. Business process mapping helps to understand the current state of the process, identify areas for improvement, and design the future state of the process. A BA should use business process mapping to identify the key recruitment steps and stakeholders for the Salesforce application. References:
