When scoping a Revenue Cloud project, it's essential to involve key customer teams that will be impacted by or contribute to the implementation. These teams typically include Information Technology, which will handle the technical aspects of the implementation; Sales Operations, which is responsible for the processes and strategies surrounding the sales efforts; and Accounting and Finance, which will manage billing, invoicing, and financial reporting aspects of the solution. Involving these teams ensures that all necessary requirements are captured and that the solution aligns with the organization's technical capabilities and business processes.
