Which functionality in Smartsheet helps manage task dependencies?

The dependency features in Smartsheet are specifically designed to manage and track the relationships between tasks, allowing users to establish how tasks depend on one another in a project. By utilizing these features, you can set up dependencies such as "Finish to Start," "Start to Start," "Finish to Finish," and "Start to Finish," which creates a more interconnected and manageable project timeline. This functionality is crucial when planning activities since it visualizes how delays in one task can impact other related tasks, ensuring better workflow management and resource allocation.

In contrast, while linking tasks is a related concept that facilitates connections between tasks, it does not provide the full range of dependency management tools that are encompassed within the dependency features. Email notifications and automatic reminders serve valuable roles in communication and task follow-up but do not inherently manage how tasks are related to one another concerning project timing and progression. Therefore, the dependency features are the most appropriate choice for effectively managing task dependencies in Smartsheet.
