(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.
Hi, the project finish date is almost 2 years delayed, which constraint shall I use in P3? The data date after I put the constrainst will be the project start date. When I use the mandatory constrainst, the total float will be zero for that activity while the successors has negative floats. When I use the late constrainsts, it has no negative floats. When I use the early constrainst, the applied activity has negative floats. So which one shall I use. I want to show the result of these constrainst to claim Extenstion of time. Can you elaborate the difference between them?
1. Early constrainst - start
2. Early constrainst - finish
3. Late constraint - start
4. Late constrainst - finish
5. Start on
6. Expected finish
7. Mandatory start
8. Mandatory finish
9. Float constraint - zero total float
10. Float constriat - zero free float
Thanks guys.

Many forensic analyst eliminate all constraints in their delay analysis schedules as constraints fool the traditional CPM backward computations.
Even for the most simple of the delay analysis technique, the TIA as a contemporaneous method is frequently performed with some avoidance of constraints. Some perform the TIA in a further simplified way by eliminating all constraints and using logic to replace them, this includes the elimination of the project must finish date which imposes a constraint on the job. The following methodology accepts only contractual constraints but suggest methods to reduce the distraction they cause.
Dear Mr Num Lock
As for the extension of time , you should schedule the activity as it is impacted like
for example as original planned
the activity was planned to start on 1 jan 11 then end on 31 jan , which is supposed your project end date
Now due to delay due to same event this activity does not start at 1 jan , now it started on 15 jan , it means there is a 15 day delay , now you should schedule by starting the activty on 15 jan and finish date of 15 feb
while to show delay
go to project overview and put project to completed on 31 jan 11 and schedule it
you will see a negative float which shows delay
i hope this may help you
