Using
Microsoft Project
Microsoft Project does have the ability to create a network
project diagram. Your best approach, however, is still to create the network
diagram as described in this chapter. Then, once the initial creation is
complete, transfer the plan to Microsoft Project. As you make adjustments to
your network diagram on the whiteboard, you can update the changes in Project to
see their impact.
When you enter a task into Microsoft Project, you will assign
constraints to the task to signify when its completion should occur. The nature
of your project, your units of work, and the urgency of the task will determine
the type of constraint you assign. Constraints in Microsoft Project are
flexible, semiflexible, or inflexible:
-
Flexible constraints These constraints do
not have dates assigned to their activities and are only bound by their
duration, and predecessor and successor activities. Use flexible constraints as
much as possible.
-
Semiflexible constraints These constraints
do have date values associated with them but also require that the tasks begin
or end by the specified date. Use these constraints sparingly.
-
Inflexible constraints These constraints
also have date values associated with them but are very rigid. Constraints that
are inflexible require that activities happen on a specific date. Use these
constraints very sparingly.
Here are the eight types of constraints you’ll encounter:
-
As Soon As Possible (ASAP) When you
specify a task constraint of ASAP, Microsoft Project will schedule the
associated task to occur as soon as it can. This is the default for all new
tasks when assigning tasks from the start date. This constraint is flexible.
-
As Late As Possible (ALAP) When you have a
task with this flexible constraint, Microsoft Project will schedule the task to
occur as late as possible without delaying dependent tasks. This is the default
for all new tasks when scheduling tasks from the end date.
-
Start No Earlier Than (SNET) A task
assigned the SNET constraint will start on or after a specific date. This
constraint is semiflexible.
-
Start No Later Than (SNLT) This
semiflexible constraint requires that a task begin by a specific date at the
latest.
-
Finish No Earlier Than (FNET) This
constraint requires that a task be completed on or after a specified date. This
constraint is semiflexible.
-
Finish No Later Than (FNLT) This
semiflexible constraint requires that a task be completed on or before this
date.
-
Must Start On (MSO) A task with this
constraint must begin on a specific date. This constraint is inflexible.
-
Must Finish On (MFO) This inflexible
constraint indicates a deadline- orientated task. The task must be completed by
a specific date.
