Project managers struggle to manually calculate critical path and slack time in MS Project, wasting hours on complex forward/backward pass calculations

Project managers using MS Project 2010 spend significant time trying to understand and manually verify forward and backward pass calculations for activity-on-node diagrams, often getting confused by how the software calculates critical path and slack. The built-in visualization and documentation are inadequate, forcing users to seek external help on forums, and current solutions don't provide clear, step-by-step guidance integrated into the tool itself.
