For each Activity the Critical Path Method calculates the earliest and latest dates. In the following example the earliest is Monday the 4th and the latest is Friday the 8th.
However in the example there is a predecessor which has a planned date one day after its earliest date. The predecessor's planned date pushes the start date of this activity one day later too.
The project manager has selected an Activity Target date of Wednesday the 6th, it will be adopted if possible. In this case it is possible, otherwise the closest available date to the target date would be adopted.
If there was no Target date then the prior planned date, or the closest available date to the prior planned date would be adopted.
If there was no Target date and no prior planned date the earliest available date would be adopted.
Backward Scheduling
For each Activity the Critical Path Method calculates the earliest and latest dates. In the following example the earliest is Monday the 4th and the latest is Friday the 8th.
However in the example there is a successor which has a planned date one day before its latest date. The successor's planned date pushes the finish date of this activity one day earlier too.
The project manager has selected an Activity Target date of Wednesday the 6th, it will be adopted if possible. In this case it is possible, otherwise the closest available date to the target date would be adopted.
If there was no Target date then the prior planned date, or the closest available date to the prior planned date would be adopted.
If there was no Target date and no prior planned date the earliest available date would be adopted.
