need to automatically set start and finish of summary tasks based on duration
and and start of project date. Is PERT Tool valid to use?
and and start of project date. Is PERT Tool valid to use?
Steve House said:The Project finish date is the date when the latest finishing task in the
project is done. It is good practice and contributes to clarity to have a
"Start" milestone at the begining of the project and a "Finish" milestone at
the end. Another rule of thumb is that all subtasks except for those
milestones will have both predecessor and succesor links. This results in
one or more chains of tasks flowing through the project and all subtasks are
a part of one of more chains. If a task has no other predecessor, the
project start milestone is its predecessor. If a task has no other
successor, the project finish milestone is its successor. Thus the project
finish date is the date displayed for the finish milestone, also the date
that the longest chain of events in the project finishes. This chain of
events is also the "Critical Path" by definition. Note that I am referring
to subtasks also sometimes called "performance tasks" here, observable
physical activities in other words, here. Summary tasks are simply
artifacts inserted for reporting and organizational purposes - in a well
designed project plan you could remove all the summary lines while leaving
all the subtasks in place and the schedule wouldn't change, all the work of
the project would still get done.
Be careful about using the terms "first task" and "last task" - I'm not
talking necessarily about the first in the list and the last in the list,
I'm talking about the first to start and the last to finish.

You both also confirm my understanding of the logic or operation of
summary
and child row however - addressing back to Steve - the linking of the
first
child of each summary thru the last child of that summary then linked to
the
subsequent summaries row first child..and so on until the last summary row
and thru to its last child row. Questions
1- unless the last child row of the last summary row is connect to
something
link the project end date.. how would the end date be calcuated ?
2- Maybe I should have made this statement at the begining of this
posting,
as follows.
Today the project users launch a Excel Spread sheet to manage their
projects
and as part of the evaluation, planning to convert their Excel Spread
sheets
into MS Projects there are several templates such as a project manager
schedule sheet that has a Excel calcuation which has embedded the duration
of
each summary task or phase already plugged into the sheet. Therefore once
the project manager launches his Excel Spread sheet he simply enteres in
the
planned start date and the spread sheet calculates the planned project
finish
date(irrespective of holidays and weekends), as well as the summary row
dates.
My attempted feasability solution for converting to MS Projects is the
process which you have just provided answer too - - except for the use of
the
last part include in point one above. How do we arrive at the Finish date
if
the last link being the last child of the last summary row is not
connected
to anything?
Thanks Very Much

SunBird said:Thanks that works. However the point that does not seem to be working
as planned is have a predetermined duration fixed between each
summary task therefore when the start project date is entered into
the this template all the planned start and finish dates will be
automatically generated based on the duration of each group of
summary task. Need your feedback...Thanks
