What determines whether a task is dependent on another task?

A task is considered dependent on another task based on its predecessor assignment. In project management, a predecessor is a task that must be completed before a subsequent task can start. This dependency is essential for establishing the sequence of activities and understanding how they are interlinked—leading to better planning and scheduling. For instance, if Task A must be completed before Task B can begin, Task B relies on the predecessor assignment of Task A. This relationship ensures that the workflow and timelines of the project are maintained effectively.

The other choices do not specifically define task dependencies. While completion dates might influence when a task starts, they do not inherently establish the dependency relationship. Resource allocation relates to the assignment of personnel or equipment to tasks but does not determine the order in which tasks must be executed. Similarly, the task description provides information about what the task involves but does not address how it relates to other tasks in terms of execution order. These aspects can be important in project management, but they do not define dependencies between tasks like predecessor assignments do.
