A backward pass is a technique used in project management to determine the latest possible start and finish dates for each activity in a project. It is also known as a “backward scheduling” or “backward planning” technique. The backward pass begins with the end date of the project and works backwards to determine the earliest possible start date for each activity.
The backward pass starts by determining the end date of the project. This is usually determined by an external factor, such as a customer deadline or a regulatory requirement. Once the end date has been established, the backward pass works backwards from this point to determine the earliest possible start date for each activity in the project. This process takes into account any dependencies between activities, such as one activity needing to be completed before another can begin.
Using a backward pass helps project managers to plan their projects more accurately and efficiently. By working backwards from the end date, they can ensure that all activities are completed on time and that there are no delays due to dependencies between activities. Additionally, it allows them to identify any potential risks or issues early on in the project, which can help them to take corrective action before it is too late.
