Finish-to-start question


I have a question regarding the "finish-to-start" relationship:

"A schedule activity may begin 10 days before the predecessor activity finishes."

Why this is an example of "finish-to-start" relationship? The successor actually starts 10 days before the predecessor finishes, not that the successor starts after the predecessor finishes. So I am very confused here.

Thanks for sharing your feedback!

A Lead enables successor activity to begin soon.And also you can refer the follow link which showcase the relationship of the finish to start relationship with diagramatically.

There will be more guides for these kind of activity. - Steven C Wyer
