Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

I think the usefulness of SS relationships needs no discussion.
There´s two situations in which FF ralationships are a must:
- When the succesor activity is shorter in duration than the predecesor.
- After the predecesor in a SS relationship has started, progress override breaks the relationship and it is left without a succesor, therefore it would appear to have a large float until the end of the project duration. An FF relationshio to replace the previos solves the problem.

If the completion of two activities are physically dependent to each other then FF relationship is a must. Avoiding the use of FF and/or SS relationship would make a CPM programme easy to maintain when you status the programme.

There are many reasons for using FF relationships. For example, such a relationship will properly show the effects of a delay to the predecessor on the successor activity.
