TMGR: Zero Work Tasks Schedule Differently

MORE INFORMATION

Tasks that have zero work are not scheduled according to either the team calendar or a people calendar. Therefore, task dates may look incorrect when relationships exist and zero work is scheduled. This becomes more apparent if lead or lag time is applied to the link. Consider the following example:

    Task Name   Start             Finish             Predecessor
    -------------------------------------------------------------
1   Task1       11/6/96 8:00am    11/6/96 5:00pm
2   Task2       11/7/96 8:00am    11/7/96 5:00pm     1SS+1 Day
				

Task2 begins 1 day after the start of Task1; one day in this example is equivalent to 8 hours. When there is work on Task2, the team calendar pushes the start to the next available working time, that is, 8:00am the next day.

If however Task2's work is set to zero, then its start date reschedules to 11/6/96 5:00pm, that is, exactly 8 hours after the start of Task1.

NOTE: Lead and lag time is always calculated based on the team calendar and not on people calendars.
