Explanation
The best way for the consultant to present the information about how sales reps use Salesforce to work a deal is to utilize a Business Process Map. This map will provide an overview of the process, and can be used to explain how each step of the process works. Additionally, a Business Process Map can also be used to identify areas of optimization and improvement, as well as to document any changes that need to be made. A Sales Architecture Map, System Landscape Diagram, and Entity Relationship Diagram are not suitable for this purpose.

The Opportunity Percentage Split method in Salesforce allows for revenue sharing among team members. Each member can be assigned a specific percentage of the revenue. This method is ideal when the split percentage is less than 100% of the revenue amount because it allows for granular control over how revenue is distributed among team members. According to Salesforce documentation, Opportunity Splits can be set up to reflect different sales scenarios, including revenue recognition and compensation. The Opportunity Percentage Split method specifically supports scenarios where splits add up to less than 100%.
