To address the comprehensive, multi-step process automation requirement at Northern Trail Outfitters (NTO), a single flow orchestration that uses Stages and Steps is the best solution.

Flow Orchestration in Salesforce:

Stages and Steps:Flow Orchestration allows Salesforce admins to build sophisticated automations by structuring the flow into Stages (representing different parts of the process) and Steps (individual actions within each Stage).

User Inputs and Automated Actions:By leveraging Stages and Steps, Salesforce Flow Orchestration can handle both user inputs and backend automated steps seamlessly, ensuring the entire process is automated and organized efficiently.

Error Handling and Conditional Logic:It also allows for conditional logic and error handling, ensuring that the flow can adapt to various scenarios that may arise during the automation process.

Comprehensive Process Automation:

Single User Execution:Given that the requirement specifies that a single user will execute the process after a case record is created, Flow Orchestration is ideal as it can manage the end-to-end process in a structured manner, without requiring multiple flows or complex configurations.
