As a project manager scheduling tasks for a software development project, you have Task 1, which involves completing the application coding, and Task 2, which involves starting the application testing. Task 2 cannot begin until Task 1 is fully completed.
What type of predecessor-successor relationship exists between Task 1 and Task 2?
The correct answer is Finish-to-Start. In a Finish-to-Start (FS) relationship, the successor task (Task 2—starting the application testing) cannot begin until the predecessor task (Task 1—completing the application coding) has finished. This is the most common type of task dependency in project scheduling.
The other options are different types of relationships:
Start-to-Finish: The successor task cannot finish until the predecessor task starts, which doesn't apply in this scenario.
Start-to-Start: The successor task cannot start until the predecessor task starts, meaning both tasks may begin simultaneously, which isn't the case here.
Finish-to-Finish: The successor task cannot finish until the predecessor task finishes, but the successor can start anytime. However, in our scenario, the successor cannot start until the predecessor is complete.
