Adjusting task link relationships
Initially, the tasks are linked with finish-to-start
relationships, so the successor task is scheduled
to begin when the predecessor task finishes.
Before task 2 can begin, you need to allow an extra day for the copyedited manuscript to
be shipped to the author. You do not want to add a day to the duration of task 5 because
no real work will occur on that day. Instead, you enter a one-day lag between tasks 1 and 2.
This lag time delays the start of
the successor task by one day.
However, task 3 can start as soon as task 2 is halfway completed. To make this happen,
enter a 50 percent lead time between tasks 2 and 3.
This lead time schedules the successor task
to start before the predecessor task finishes.

You can enter lead and lag time as units of time, such as two days, or as a percentage of the
duration of the predecessor task, such as 50 percent. Lag time is entered in positive units
and lead time in negative units (for example, –2d or –50% ). You can apply lead or lag time
to any type of task relationship: finish-to-start, start-to-start, or any other types.
Places in which you can enter lead or lag time include the Task Information dialog box
(Task tab), the Predecessors column in the Entry table, the Task Form (View tab, Split
View group, Details command), and the Task Dependency dialog box (viewable by
double-clicking a link line between Gantt bars).
The scenario: At Lucerne Publishing, editorial and design work on a new children’s
book is about to begin. At this stage, you have an initial plan with task names,
durations, relationships, and resource assignments. Now you want to fine-tune those
task relationships.
