Hello
Please can someone help me!! I am working with P6 and have come accross a problem that I am stuck with at the moment. Apologies if this has been asked before I have had a quick look through past activities but cant find the same problem and not to sure how to do a search?
I have a schedule where I have added activities and where certain activities have various resources attached to the same activity.
ie Task 1 total 15 days (based on a mon-friday calender) I have attached a resource which also uses the same calender but I have also attached a resource which has a 6 day week or mon-sat calender and I want to show both resource on the activity but one working for 15 units (based on 3 x 5 day weeks) and the other using 18 units (based on 3 x 6 day weeks)
Is this possible? Do I need to make the activity based on the larger 6 day week or am I going wrong somewhere else?
Thanks in advance for any help!
Thanks Khaled. Much appreciated :-)
go to imterpice then recouces curves in the main minu:
define that the R1 corve as following :
R1 required from d1 to d5 meens that they will finsh after 50% of the total activity duration .

Hello
Can anyone kindly help me out in the below?
I have an activity A1 in P6 which has 3 resources, say R1, R2 & R3.
A1 has a fixed duration of say 10 days (d1 to d10) and the schedule of resources are as below.
R1 required from d1 to d5
R2 required from d3 to d7
R3 required from d6 to d10
On view of the above, Can you please tell me now can I set these fixed resource schedules in one single activity?
Apologies if this has been already discussed before.
Kind Regards,
Nithin

Thanks again for taking the time to respond, I think we are talking cross purposes. My requirement was purely a resource numbering task. I basically needed to see the number of resource required for the duration of a project so by splitting the task into two activities happening at the same time one on a 6 day calender the other on a 5 day calender so it shows one 15 day and 1 18 day task has solved my issue.
I can now see the required number of resource throughout the project for both mon - fri working and also for mon - sat working. So in essence problem solved
Thanks again for taking the time, much appreciated.

Brian,
You are correct, it is not P6 but Spider Project. I am using Spider to illustrate how you can correctly model “shift work”, that is work done at different work hours or workdays on the same activity in the hope, this provides you with a clue.
Modeling shift work by dividing an activity into multiple activities is wrong and creates issues on how much work is to be performed by each activity. Say Activity A is divided in two, Activity A1 and Activity A2, Activity A1 has a 3 days’ work week, from Monday to Wednesday day while Activity A2 also has a 3 days’ work week but from Wednesday to Friday.
Calendar for A1= M-T-W
Calendar for A2= W-TH-F
If all work can be done with 4 man-days, with a single resource assigned to each activity then depending on the day work can start each activity will perform different amount of work.
If work can start on Monday:
If work can start on Thursday
So, depending on when work can start the optimal work split will vary, otherwise work will be delayed. However, schedules are dynamic and you do not know for sure when work will be able to start. The software shall be able to model correctly shift work because if you have hundreds or thousands of activities working on shifts the above multiples up to a point manually adjusting assignments is not practical.
If your software cannot correctly model shift work, cannot correctly account for work done by different shifts on a single activity it will yield same problems as if dividing the activity, instead of how much work will be performed by each activity the issue will become how much work is to be performed by each shift.
Best regards,
Rafael
Thanks for the responses
Roger, I have tried both ways and it doesnt seem to work,
ie I have made the task 18 days then attached the 2 different resources and it then just makes the one resource that is working a 5 day week work a 6 day week. Similarly if I use 15 days it makes the resource working a 6 day week only work a 5 day week. Very frustrating, I think I may have to split it into two tasks running at the same time one with a 6 day calender and the other with a 5 day calender to get it to work correctly?

Thanks for the response but what you are showing doesnt look like P6 to me? Is it a different view that I am not used to seeing?
Any further advice greatly appreciated!!!
Brian,
Definitively you shall define a calendar for your activity that includes all hours you want some resource to be able to work.
Your problem seems like an issue of modeling for shifts, that is when resources use different work hours, no matter if a high percentage is overlapping. Unfortunately, shift work modeling is not where P6 shines, and here it is somewhat limited.
The following figure shows two schedules, the first using a single team, this is most probably what you will model within P6 with a six days calendar for your activity, and perhaps by manually adjusting assignments you can get there. Remember manually adjusting assignments can be time consuming and error prone, try to find out a way to avoid this.
The second uses two teams, with this functionality you can correctly model work in shifts. Hope this can give you some clues.
Best regards,
Rafael

In your example, surely the task 1 total duration would be 18 days if using 3 x 6 day weeks
Task duration of 15 days (3 x 5 day weeks is Monday to Friday 3 times)
Task duration of 15 days (2 x 6 day weeks Monday to Saturday (twice) and Monday, Tuesday and Wednesday)
Might help but probably just muddy the waters
