In project scheduling, what does the term 'interdependency' refer to?

The term 'interdependency' in project scheduling refers specifically to the relationships between different tasks in a project. When tasks are interdependent, the completion of one task may rely on the completion or progress of another. Understanding these interdependencies is crucial for effective scheduling, as it allows project managers to see how tasks are connected and to plan accordingly to ensure that the project progresses smoothly.

Interdependencies can take various forms, such as:

1. Finish-to-Start: This is the most common type where one task must be finished before another can start.
2. Start-to-Start: Here, two tasks can begin simultaneously, but the start of one task is dependent on the start of another.
3. Finish-to-Finish: One task cannot finish until another task is also completed.
4. Start-to-Finish: An unusual type where one task cannot finish until another task begins.

Recognizing these relationships helps in identifying potential bottlenecks and optimizing project timelines. It ensures that resources are allocated efficiently and helps in accurately estimating project duration.

The other options, while related to project management concepts, do not capture the essence of interdependency. Independence of tasks would suggest they each proceed without influencing one another, which
