Thanks Mark that does help. i have never done a Project just listing
Milestones.
To me a critical task list would have been preferable.
It can be argued that a milestone with a duration greater than zero is
not a milestone, milestone being defined (by PMI) as a task with zero
duration. Milestones are intended to be marker points in the schedule
which tell you that some major event has occured, like "Design
Complete" or "Materials Purchased". Note that tasks are always verb-
noun, like "Design Pump Installation" or "Write Specs". Milestones are
just the opposite, noun verb, implying completion.
In over thirty years of scheduling, I've yet to see a useful purpose
for a milestone with a duration greater than zero. MS Project
developers saw fit to put in this feature, but if you have any
knowledge of the genesis of Project for Windows, you know that no one
on the team had any idea at all of how scheduling, much less Project
Management, is done. Their successors have come a long way since then,
but they've still kept a number of dubious capabilities/features in
the product.
Hope this helps in your world.
