Here’s a word to the wise: Use constraints only when you absolutely need to
force a task’s timing.
Table 4-1 lists all the constraints and an explanation of their effects on your
As Soon As Possible
The default setting; the task starts as early in the schedule
as possible based on dependencies and the project start
As Late As Possible
The task occurs as late as possible in your schedule,
based on dependencies and the project finish date.
Finish No Earlier Than
The end of the task cannot occur any earlier than the date
Finish No Later Than
The end of the task cannot occur any later than the date
Must Finish On
The task must finish on an absolute date.
Must Start On
The task must start on an absolute date.
Start No Earlier Than
The task cannot start any earlier than the date you specify.
Start No Later Than
The task cannot start any later than the date you specify.
You can set only one constraint for a task. Setting a constraint involves
selecting the type of constraint you want in the Task Information dialog box. Some
constraints work together with a date you choose. For example, if you want a
task to start no later than a certain date, you need to select a date by which
the task must start. Other settings, such as As Soon As Possible, work off a
different date — in this case, the start date you set for the whole project or
any dependency relationships you set up with other tasks. (See Chapter 6 for
more about dependency relationships.)
To set a task constraint, follow these steps:
1. Double-click a task.
