Hello All, I have a query which has been bothering me:
I'm not sure what the correct way to deal with remaining durations is. I use Primarvera P6.
eg.
Activity - Excavating Trench. Original Duration of 10 days.
Ok.
Activity Starts 1-Nov. You update progress onto this activity and reschedule your programme at the end of the week with data date 8-Nov. 7 days have gone past. Your original activity duration was 10 days. If you have completed 25% of your work - does that mean you have theoretically used 2.5 days worth of your original duration - thus adjusting your remaining duration to 7.5 days? Just because you have started this activity and worked on it - doesn't mean that you have used the entire 7 days during the week - you may have only used half a day. But it's impossible to know this with hundred of activities.
What do others do in this situation? When / how / why should you adjust an activity's duration?
Obviously on a large programme you can not ask PM remaining durations on each and every activity at the end of each reschedule.
Also - does anyone run a programme whereby you set all activities with an expected finish (as per baseline dates) at the beginning of the job and then each time you reschedule - the activity duration adjusts itself (shortens) to keep in line with expected finish. Then continue doing this until your manning increases too high in a specific area and then highlight this to PM who will then decide what he wants to do - ie increase manning to that level OR push out completion date?
This has been suggested to me as an appropriate way of scheduling.
Any feedback would be appreciated.
