Website Upgrade Incoming - we're working on a new look (and speed!) standby while we finalise the project

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.

The schedule I have activities have TF=o however they are not in critcal in the schedule report they are not exists.
I use define critical activities as Total Float Less than or equal to 0.

Hi Moutaz,

I saw already your schedule. It seems that you have too much float which is not advisable. But to answer your query why you have a Float of 2days in your START WORKING activity?, you have to adjust your lag to its Successor;

A5310 Hand Over FS 105

then your float will be Zero. Also, put FF relationship if you are linking to Milestones not FS. As what I have mentioned in my previous post, you have to link a more logical relationship to achieve a good critical path. Try to avoid to much Float its no longer realistic....200days and more...you know what i mean.


cheers,


JEFF

Rodel, the longest activity does not create the critical path and I reduced the duration of that activity but nothing happened.

Rodel, Can I send you through your personal e-mail if you do not mind?

Regards,

Moutaz

Moustaz,
It means that your longest activity create the critical path. If you reduce duration of that activity for exercise analysis you will see the effect why?

Thanks all for your response,

Rodel, the critical bar is defined and I filtered the critical actviities, I got only three activities which exist in the report and located in the longest path.

Regards,

Moutaz

Moutaz,
Try to filter critical activities and see if all activities with 0 float will show. I suspect that critical bar is not define or tick that is why it is not showing red bars.

Of course, for critical activities, what you should be quantifying is not their total float, but their drag. Just sayin’...

(The fact that Primavera doesn’t compute drag means you’d have to compute it by hand, which makes it a bit trickier and more time-consuming -- but no less important. Of course, you could just switch to Spider Project or MS Project to have the software compute drag...)

Fraternally in project management,

Hi Moutaz

Check the value assigned [I.e TF=0] for total float to mark the activities as critical. I am not sure about p6 but in p3 one can assign total float value ,check that ,it might help you

Hi Moutaz

Set the float display to 2 decimal places.

Best regards
