In a Salesforce CPQ scoping session, the first type of documentation that comes into play is the Business Process Mapping. This is because before diving into the specifics of products, bundles, order management, or quote documentation, it's crucial to understand the client's overall business processes. Business Process Mapping provides a visual representation of the client's business processes, which can help identify inefficiencies, redundancies, and gaps in the current process. It also helps in understanding how the Salesforce CPQ solution can be best configured to align with and optimize these processes1. References: Salesforce CPQ documentation1.
