I can't imagine how a "timeless" task could possibly exist. There is always
a time element, a management horizon, on everything an enterprise does. As
the project manager you need to set priorities on tasks and advise the
resources when they need to work on them in order to finish the project as
efficiently as possible, to achieve the objextives within the management
horizon while they still matter. A project is undertaken to meet a
particular business objective and that objective always has a time element
involved - the new toy has to be in the stores in time for the Christmas
shopping season, that sort of thing. So in that sense, everything in the
project has a deadline by which it needs to finish in order to achieve the
project's objectives in the timeframe required. Likewise everything in the
project has a time that is the earliest time it is possib le to start. If
nothing else controls it, it can't happen before the project begins. Most
of the time, there are things that have to happen first or a requried
resource won't be available until a certain time, that sort of thing. If
you say as a given that you want to finish the project efficiently, then the
schedule project develops is telling you earliest you CAN schedule the task
and the earliest date you can achieve your objective. If it truly doesn't
matter when you achieve it, it also doesn't matter IF you achieve it, and
it's a waste of resources even to do the project in the first place - kill
it before it even starts.
