Forward Pass. The first step in the calculation process is known as the Forward Pass. In the forward pass, the Early Start and Early Finish values for each activity, along with the overall Project Duration, are calculated. To facilitate schedule calculations, an “end of day” notation is used for both the Early Start and the Late Start values.
Forward pass is a technique to move forward through network diagram to determining project duration and finding the critical path or Free Float of the project. Whereas backward pass represents moving backward to the end result to calculate late start or to find if there is any slack in the activity.
A forward pass in project management is a technique used to move through a project network diagram. The forward pass helps you understand the project duration and calculate the early start and early finish values (meaning, the earliest day each project task can begin and wrap up). The easiest way to understand a project management forward pass ...
Feb 9, 2024 · Forward Pass Analysis. Let’s perform the forward pass on this project schedule network diagram: Start milestone early start (ES) is Day 0. Activity A ES = 0, Duration = 5 days, so early finish (EF) is Day 5. Activity B ES = 5, Duration = 3 days, so EF is Day 8. Activity C ES = 5, Duration = 2 days, so EF is Day 7.
The CPM calculation consists of two parts, generally done one after the other, in the same process: The forward pass and the backward pass. The Forward Pass. Generally, the first part of the CPM calculation is the forward pass. It consists of determining the earliest date for each activity, starting with the first activity in the CPM network.

Mar 28, 2024 · You can use CPM during the planning phase of a project to identify the longest sequence of dependent tasks and calculate the shortest possible completion time. CPM is particularly useful for optimizing schedules for complex projects with multiple activities, milestones, and task dependencies. The critical path method helps map out key tasks ...
