The process of prioritizing the business backlog should be owned by the business teams affected, with support from the internal technology teams who understand ways to maximize Salesforce's declarative features. The business backlog is a list of requirements or user stories that describe the features or functionality that the business needs or wants from a project or enhancement. The business backlog should be prioritized by the business teams affected because they are the ones who have the most knowledge and interest in the business value and impact of each requirement or user story. The business backlog should also be supported by the internal technology teams who understand ways to maximize Salesforce's declarative features because they are the ones who have the most knowledge and expertise in the technical feasibility and complexity of each requirement or user story.
