P5 for shutdown planning

Member for

All,



the way I help clients chose which duration type to use is to tell them that each activity has THREE dimensions:



Duration

Number of men

Total Manhours (duration x Number of men)



If you ask an engineer how "big" a job is, do they tell you:



Its a three day job

Its a two man job

Its a 50 manhour job



By ranking the above list, and comparing it to the order that each of those variables is recalculated by the four duration types, you should be able to work out which is best.



I am blessed with clients who scope the work for Shutdowns/Turnarounds very well. So in that world its a "50 manhour job" - so we use "Fixed duration and units"

Hi Alka



We used it for shutdown planning.

Fixed duration and units seems the best choice.

You plan with fixed durations --> no surprises with the overall duration

Fixed Units: better for the planned resource load and by this for simulations.



Good luck
