To enable the Direct Store Delivery (DSD) process, a Salesforce Administrator must configure several components. First, the Sales Manager requires the "Action Plans" permission set to create and assign tasks. The tasks themselves are defined within an "Action Plan Template," which serves as a reusable blueprint for visits; this template must include the specific delivery tasks. Finally, to grant the user access to the objects and functionalities specific to the DSD workflow, such as managing van stock, processing orders, and executing delivery tasks on the mobile app, the "Lightning Direct Store Delivery" permission set is essential.

C. Define Assessment Indicator Definitions for Delivery task: Assessment Indicator Definitions are used to define metrics for data collection during a visit (e.g., inventory count, shelf space), not for creating or assigning a delivery task itself.

D. Change the Action Plan Type Delivery: The "Action Plan Type" is a categorical field for organizing and filtering templates. While it's good practice to name it appropriately, changing this value does not enable any specific delivery functionality.
