What Salesforce declarative component can a UX designer use for onboarding?

The most suitable declarative component for onboarding within Salesforce is the onboarding checklist. This component serves as a structured guide for users as they navigate through the initial setup or usage of an application. It provides a clear, step-by-step list of tasks that users need to complete, helping ensure that they understand the necessary actions to take advantage of the platform effectively.

An onboarding checklist is particularly valuable because it enhances user experience by breaking down complex processes into manageable parts, allowing users to track their progress and focus on essential tasks without feeling overwhelmed. This leads to a smoother transition into using the system, ultimately resulting in higher user satisfaction and retention.

While field-level help can assist users by offering contextual guidance within fields, it does not provide a comprehensive roadmap or structured approach to onboarding that a checklist does. The Data Migration Assistant serves a different purpose related to importing data rather than guiding user onboarding. Lastly, a decision tree, while useful for guiding users through decision-making processes, lacks the structure and task-oriented approach that an onboarding checklist provides.
