Backward scheduling is a technique to calculate the project plan from the due date. You can assign the work packages in a way that the entire project will be finished exactly to the due date.
In the backward scheduling, a new planning element starts as late as possible. This planning element, which is the last one in the planning chain, stays at the end of the project plan. The idea of the backward scheduling is to determine the latest possible end date of this planning element to meet the planned due date. The latest end and start date of each planning element in the project plan is consequently calculated.
Therefore, the project plan is calculated until the latest possible date of the planning start by considering any necessary lags between planning elements. The slacks, critical planning elements as well as the critical path can be determined due to this calculation.
For more information on the critical path see Show the critical path.
Do the following to create a backward scheduling:
