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.

Is anybody using P5 for shutdown planning? I have used fixed duration and units as duration type. Does that sound alright. I am using P5 without any formal training. Since I have worked on P3 for many years, I have worked out most of P5 but still there is a lot to explore.

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

Dieter
