Frequency of schedule updates.
Hi, Please, correct me where I'm wrong.
I remember reading on some SDPM paper that the schedule updates should be made daily to calculate the success probability trends ¿Did I actually read that or am I just imagining it?
Now, this "Daily update" is a hard thing. How can you update daily a schedule for, say, an hydroelectric project? Given the enormous amuount of resources working at field on the same day, I consider this a very hard task. I mean, from my little experience, it is just an ideal: they gather field reports to know "how is the project going", but usually these reports don't go to the schedule (I am speaking of Mexico), the schedule is actually rarely updated. When updated, it is made based on percentages dicted by field managers "We are 15% ahead, but don't ask me how much have I expend. I need time to gather the information and give you an estimate"
What I'm trying to know is, what is the required effort to actually track objective data from field to feed the project database? Can this be done daily? Is there some project doing it?
