PERT and "expected" versus "standard Gantt" view

C

Clive Long,UK

Hi,

I like the idea of using PERT for worst-case scenario calculations.

Of course, trying to get decent estimates for any task is a skill
in its own right.

Anyway, say I have decent optimistic estimates for the tasks, then
I add 10% and 40% contingency to the task durations using Excel - and
I post back in all the durations into the PERT form.

Then I get project to perform the PERT calculation and end up with
optimistic / expected / pessimistic schedules

Now.

I find the EXPECTED and the STANDARD GANTT views to give me
different schedules. I feel that Expected should equal Standard. They
are close in dates and durations, but not identical.

Any ideas on why this is so? Which is my "usuable" plan? i.e. which
can I enter items 100% complete etc.?

Regards


Clive
