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.

Hello all

I have been facing situations with resources. I would like your comments ...

The method I adopt once I make the programme is to allocate resources based on production rates, Now I keep the Freeze resources option in P3 unchecked. As such as the programme gets updated (I dont update percentage complete on individual resources as it seems impossible
) as the bugeted quantity is fixed, the unit per time period increases... this is not much of an issue.

the real problem is most of the times I have activities that get suspended for months after it has started or donot get 100% complete ( for example due to obstruciton of area)as such in the programme my activity bar extends far beyond the original duration. In this situation the resources get allocated to all the days and as such when I project the resources using graphs the resource requirements are very high.

I have tried suspend and resume function but I donot believe it helps.

Now the consultants require the resource graphs to be realistic. I have finally only one option that is to get down to each activity and reduce the units per time period and some times bugeted quantity for activties with actual start dates.This way the units per time period donot follow the production rates. I have to adopt this to meet the consultant requirements.

Can any 1 explain how resources are manipulated in P3

Never use the option freeze unit per time period, never. ! !!!!

An easy solution is to load a dummy resource call it manhour, assign it to all your activities. Assign your budget to it.

In each update you have to get your actual budget for work performed, the total manhour spent by activity, you load to your resource.

and to avoid showing curve with mixed resources, assign 1 $ to your price unit of resource manhour, ( the other must be zero) and show your curve base on cost.

Good luck

Shareef,

It has been a few years that I used P3…let see if my memory serves me right!!!
The man-hours or the 12 units that were loaded initially to the activity were the planned units rather say budgeted units. If the activity is complete in one day instead of 3 days there should be no change to the budget. Budget stays the same…
If you want to update program for the Actual manhour then update the EAC.

I no longer have P3, we used only for a couple of jobs then we were required to use SureTrak and moved to it for a few years. Because we got new computers which use Windows 7 we cannot use SureTrak unless using Virtual Machine, is free but intrusive so we decided also to give it obsolescence and moved to Spider Project.

Eventually my memories of P3 will vanish completely as we stopped using it years ago, for us it no longer makes sense to use software no longer upgraded nor supported by the supplier, we must learn our new more modern and powerful tool that works well on Windows 7, 32 bit and 64 bit versions. Wish you well.

Best Regards,
Rafael

Hello

I have encountered a new problem again!!

let me give you a situation:

Suppose I have an activity of 4 days duration and this activity has a resource say Labour with 3 units per time period. Thus the budgeted quantity for this activity is 12 units.

Now consider the case when this activity actually gets completed in 1 day lets say with 3 units ( yes my planned budgeted quantity was wrong), here the programme gives units per time period as 12 ie 12 units of labour for 1 day instead of 3 units(this can be done by resource loading-resource projection).

Note: I have kept the P3 option" Freeze units per time period" unchecked.

Now my questions are:

1. Should I keep the Freeze units per time period option checked while updating a programme. This will change my budgeted quantity. Is there some methodlogy that I am missing?

2. Should I update the actual resource utilization as to do this would be like impossible as there are a lot of resources and a lot of activities. and if yes how should i do it.? Is there some way of using import export function to do this?

Some one with experience in Primavera p3 can help me here!!!

Distribution of resources is assumed uniform for in progress activities unless you apply post period performance, a procedure that can be irreversible. If you have not applied the posting the average will continuously be revised until the activity is finished and the distribution will be assumed uniform. This can make your S Curve performance to vary among previous periods on every update. We used SureTrak where we could not record period performance and the S Curve behavior could not match actual progress per period.

If you have not applied this procedure along several updates you might be in trouble, some have devised procedures to solve the issue in several ways.

Maybe, if occurrence is not much you can split the activity into separate activities and this can solve the issue. Otherwise look for “post period performance” in your P3 help and manual. Also try a search at PP for the keywords “period performance”.
