Setting task constraints
Adjusting relationships between tasks and entering lead or lag times where appropriate
are excellent techniques to fine-tune task relationships so that you get the results you
want. However, Project cannot automatically make such schedule adjustments for you. As a
project manager, you must analyze the sequences and relationships of your tasks and use
your best judgment when making such adjustments.
Setting task constraints
Every task that you enter into Project has some type of constraint applied to it. A constraint
determines the degree to which that task can be rescheduled. There are three categories of
Flexible constraints Project can change the start and finish dates of a task. The
default constraint type in Project is that tasks start as soon as possible. This type of
flexible constraint is called As Soon As Possible, or ASAP for short. No constraint date
is associated with flexible constraints. Project does not display any special indicator in
the Indicators column for flexible constraints.
Inflexible constraints A task must begin or end on a certain date. For example, you
can specify that a task must end on November 13, 2015. Inflexible constraints are
sometimes called hard constraints . When an inflexible constraint has been applied to
a task, Project displays a special indicator in the Indicators column. You can point to a
constraint indicator, and the constraint details will appear in a ScreenTip.
Semi-flexible constraints A task has a start or finish date boundary. However,
within that boundary, Project has the scheduling flexibility to change the start and
finish dates of a task. For example, let’s say a task must finish no later than June 19,
2015. However, the task could finish before this date. Semi-flexible constraints are
