What are the characteristics of a Start-to-Finish relationship?

In a Start-to-Finish relationship, the successor task must begin before the predecessor task can be completed. This type of dependency is less common than the more typical Finish-to-Start relationship, but it is crucial in certain project management scenarios where the initiation of one task depends on the ongoing activity of another.

For instance, this relationship could apply in a situation where the predecessor task is a system that must remain operational before a new system can be fully implemented (the successor task), meaning that the successor must start operating to transition successfully without shutting down the predecessor entirely. Understanding this specific dynamic helps project managers plan and execute timelines effectively, ensuring that dependencies are appropriately addressed.

The other options describe different types of task relationships that do not align with the Start-to-Finish definition. Familiarity with these characteristics allows for accurate task management and scheduling, which is essential for successful project execution.
