(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 Naveen
Daniel has given you a good explanation regarding time impact analysis but it is not that simple.
You should only use time impact analysis for work in progress.
If something has happened to hold up the work you need to put in a task that represents the delay period.
Save the file under a new name.
You should then link the delay to the delayed activities and reschedule to see what happens to the end date.
The method only works if you have a fully detailed bottom up programme that responds realistically to impacted events.
If your programme is full of FF SS Links - lead lags - constraints etc then you will get a misleading response.
Remember that the result is always theoretical and will change as circumstances change.
Best regards

That means we can make use of time impact analysis when we seek EOT, right?. got it. Thanks a lot for your valuable information
Hi Naveen,
Okay let me explain further, the term "Time Impact Analysis" means you are assessing or analysing the impact of a certain activity or event and how it affects the programme, especially your contractual critical dates and/or completion dates. These are normally used to see the impact of change orders or variations or any unforseen event which caused a delay.
What if analysis are more like a programme study or programme analysis of various scenarios, so it helps the managment to decide and select the best option.
Best regards,
Thank you for your reply. I am satisfied with your reply reg. schedule analysis but for time impact analysis, could you explain in what situations we use it and how to perform (means can we do it through what-if analysis??)
Schedule analysis could just be about anything in the programme, a thorough schedule analysis would mean reviewing the following:
Logic and sequence of works
Duration and produciton rates
Quantities
Project contraints
Procurement and delivery of long lead items
Calendar usage
critical path
Milestones and Key Dates
On the other hand, "time impact analysis" nornally talks about an event or group of events and their impact or effect on the programme especially on critical key dates.
