Article: Schedule by Work vs. Schedule by Duration
The "Duration" column in the task list allows you to set the length of time you are allowing for a task to be completed. The Work column allows you to specify the amount of time a task will take, which can differ from the duration of the task. For example, a task can have a value of 4 Work hours, while at the same time, giving the user a 2 Day Duration. Essentially, you are stating, "I know this task should only take 4 hours to complete but because there are other activities going on, I am allowing a 2 day window for those four hours of work to be completed."
By default, Viewpath will schedule your tasks by Duration. Upgraded users can choose to schedule your tasks by Work.
It is also important to note the Resource Allocation is based on Work hours and not Duration.
To see a schedule based on the amount of work assigned to each task, select the checkboxes for the task(s) you wish to scheduled by Work, then click "Advanced" on the toolbar. Select "Schedule by Work".
In our example above, Gail has 50% availability for this project. When choosing Schedule by Work, the duration changes to 12 hours, and the finish date adjusts to accommodate 6 hours of work, instead of the 2 day duration. You can use Schedule by Work for certain tasks, or for the most accurate scheduling, use it for your entire project.
