Fixed Duration

Can you explain the difference between Fixed Duration Effort ON and Fixed Duration Effort OFF?

RE: Fixed Duration

The three task types are fixed units
fixed-unit task: A task in which the assigned units [or resources] is a fixed value and any changes to the amount of work or the task's duration do not affect the task's units. This is calculated as follows: Duration x Units = Work.

fixed-work task: A task in which the amount of work is a fixed value and any changes to the task's duration or the number of assigned units [or resources] do not affect the task's work. This is calculated as follows: Duration x Units = Work.

fixed-duration task: A task in which the duration is a fixed value and any changes to the work or the assigned units [that is, resources] don't affect the task's duration. This is calculated as follows: Duration x Units = Work.).

Project uses fixed units by default.


When working with effort-driven scheduling, keep the following in mind:

The effort-driven calculations apply only after the first resources are initially assigned to the task. After the first resources are assigned, the work value doesn't change as new resources are assigned to or removed from the same task.

MS Project tip:

Link tasks using predecessor column - project

a. First, note ID number of the task you want to link to (predecessor). Then, in the predecessor column of the task you want to link to (successor), type the predecessor task's ID number.
b. The link will be a Finish to Start (the default type).
c. Or you can add in a code for a different relationship type
i. SS = Start to Start
ii. FF = Finish to Finish
iii. SF = Start to Finish
d. You don't have to type the task ID numbers in any specific order, but you must separate multiple tasks with commas.
