The delay between two tasks is measured by indicating the days of the week for the week that contains the Planned Completion Date of the predecessor.
For this Lag Type, each day of the week is associated with a number:
- Sunday=1
- Monday=2
- Tuesday=3
- Wednesday=4
- Thursday=5
- Friday=6
- Saturday=7
If you want to indicate that the Planned Start Date of the successor should fall on a Tuesday of the current week, and the Tuesday is prior to the Planned Completion Date of the predecessor, you would code your successor with the following formula:
4fs-3w
Note: If the Tuesday passed for the week of the Planned Completion Date of the predecessor, then the Planned Start Date of the successor task is the first available working day of that week.
If you want to indicate that the lag should fall on a Saturday of the current week, and the Saturday is after the Planned Completion Date of the predecessor, you would code your successor with the following formula:
4fs+7w
If Saturday is a non-working day, the next available day after Saturday (to indicate positive lag) is selected as the Planned Start Date of the successor.
To indicate past or future weeks, you can add a number in front of the day number for the lag type.
For example, to indicate the Monday of 10 weeks ago, you can use this code to indicate the predecessor of your successor:
4fs-102w
10 indicates 10 weeks ago, and 2 is the number assigned to Monday.
