Question

Almost all tasks in a project will be connected using either _____ or _____ dependencies.Select an answer:a)start-to-finish; finish-to-finishb)finish-to-start; finish-to-finishc)finish-to-start; start-to-startd)start-to-start; start-to-start

Answer 1

Answer:

b) finish-to-start; finish-to-finish

Explanation:

The most common dependency is finish-to-start.

Finish-to-finish (FF): A logical relationship in which a successor activity cannot finish until a predecessor activity has finished.

In simple terms, two activities can run concurrently, but one cannot finish before the other finishes. Example? The PMBOK® Guide gives a good example too. Writing a document (predecessor) is required to finish before editing the document (successor) can finish.

Answer 2

Answer:

c) finish-to-start; start-to-start

Explanation:

Project dependencies are the time relationships between a predecessor and a successor in project management. In other words, these dependencies describe which activity among the two needs to start earlier or later and when it needs to start or finish compared to the other one.

The most common type of dependency in all projects (no matter the nature or industry) is the finish-to-start one, where the activity A needs to be completed before activity B starts, e.g. base nail polish has to be put before the top coat gets put on the nails.

The second most common type of dependency is the start-to-start one, where two activities need to start at the same time. This is common for activities where synchronization is paramount.
