Sales reps and sales operations are two groups that should provide content for the use cases for sales processes. A use case is a description of how users perform tasks or achieve goals using a system or process, such as creating an opportunity or closing a deal. A use case typically includes information such as actors, preconditions, postconditions, main flow, alternative flows, and exceptions. Sales reps are the primary users of sales processes, so they should provide content for the use cases based on their experience and needs. Sales operations are responsible for designing and optimizing sales processes, so they should provide content for the use cases based on their analysis and best practices.
