If I need to set up a new project with a non optional deadline of getting a water station into operation so it can serve the local area, would that be classed as the sucessor and would it be a finish to start project(ie back to front)?

Hi Jo

Thanks for your question - good example too. The thing that would help you decide is the question: "Which of the two tasks is driving or positioning the other? Once you've chosen the predecessor (or driving task) you can then decide if it's the start or finish that's doing the driving. Finally you can assess if it's affecting the start or finish of the successor. With all that in place you may indeed end up with a task in the future being the predecessor to an earlier task with a Start Finish relationship.

Hope this helps, do let us know if you have any other questions. Kind regards,

Andrew
