Adding to John's comments, one of the pitfalls of your approach is that
Project is best used to figure out the schedule you need to follow, not just
to document what you've already decided will be the schedule and check off
performance against it. If Joe is to be updating the server with module X,
do you really need to document each individual miniscule step he must take?
If I were Joe, I'd be really ticked off at you for not trusting me to know
how to do my job. Just tell me I'm responsible for updating the server,
everything will be "go" for me to do it starting Tuesday afternoon, and then
get out of my way and let me do my job <grin>. From a project managment
perspective it's usually enough for the PM to say "Update Server with Module
Package X, 5 hours duration, starting Tuesday 1pm" and leave it up to Joe
how he organizaes the details. We could care less if he copies File XYZ
between 14:00 and 14:10 or between 14:42 and 14:57. All that really matters
from a planning standpoint is the server will be down for upgrades starting
Tuesday 13:00 and back online with the upgrades done Tuesday about 18:00.
Especially in IT projects many PMs use what is called the "8/80 Rule" as a
guideline - if you're working with tasks much under 8 hours duration you're
micromanaging way too much, losing sight of the big picture in a morass of
pointless detail, and if your tasks are longer than about 80 hours you're
probably erring in the opposite direction, not decomposing the work into
enough detail.
I like to approach it from the standpoint of detailing the tasks down to a
one task - one resource correspondence, "resource" meaning in this context a
skill package of one or more individuals. If I'm painting a room and the
painter and his assistant (one skill package with two individuals) will box
up the computers in it, move the furniture out, remove fixtures from the
wall, mix and apply the paint I'll just list it as one task "Paint the
Room." But if people from IT are coming in to box up and move out the
computer equipment, a team of laborers to move out the furniture, union
rules require it is a carpenter who takes down the wall fixtures, then the
painter mixes and applies the paint, "Paint the Room" becomes a summary task
with those individual activities detailed under it.
