Learn how to use forward pass and backward pass to calculate project duration, critical path, float and slack using network diagram. See examples, definitions and videos on Tiemchart blog.
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.

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).
A backward pass in project management is a technique used to move through a project network diagram. The backward pass identifies your late start and late finish values, so that you can understand the project’s duration and eventually find the critical path .
The critical path method formula has two parts; a forward pass and a backward pass. Forward Pass in CPM. Use the CPM diagram and the estimated duration of each activity to determine their earliest start (ES) and earliest finish (EF).
Mar 28, 2024 · The critical path formula consists of two parts: the forward pass and the backward pass. The forward pass calculates the earliest start times (ES) and finish times (EF) for each activity, with EF determined by adding the activity's duration (t) to its ES.
