I found a video on YouTube that might be helpful. The video is titled “Operations Management 101: Conducting Critical Path Analysis Part 2” and is presented by Brandon Foltz. In this video, Brandon Foltz discusses project management and how to construct a critical path network using the forward and backward pass method. He also explains how to find the earliest start, earliest finish, latest start, and latest finish of the project . The example used in the video comes from the book “Operations Management” by Heizer and Render .
