"IF" variables in project

[Tracey]

Can I create an "if" relationship between 2 tasks.? Eg. I have a task that
involves technical drawings. Once the drawings have been completed & checked
they go to the client for review. If the client is happy the next step of the
process is "internal sign off", if the client wants changes, the drawing &
checking process must reoccur (under a different summary task called
"extended D/O hours"). If "Client review" = 100% then "Internal sign off"
must pick up the client review finsh date, If the "Client Review" does not =
100 %, the task "extended drawing time" must come into effect. This sounds
very complicated, but in this process I have 2 scenarios that could occur & I
cannot plan which will be the actual. Is there another way of doing this?
I know that I can create a custom field with an IIF statement, but then I am
not sure how to track the % complete or how to calculate the total hours
spent on the drawing.

Thanx
Regards
Tracey

Hi,

I'm afraid you'll have to decide which is the most likely and plan that
one - change it when necessary.
Project will only calculate one plan at the time.

Hope this helps.

Project does not allow conditional branching. However, this behavior can be
modeled with Risk+ and you can estimate your total task duration according to
the probabilities you set for the branches.

This type of customer redirection is normally a risk item. Assign some risk
money to it, save it as a planning package. In the worst case, assume a
reasonable amount of rework. Your customer will never be mad if you deliver
early if no additional rework is required.
