Scheduling & Critical Path: Step-by-Step Method

What this note covers

1. Set up correctly: from precedence table to activity network
2. Forward scanning: lock in earliest times, left to right
3. Backward scanning: the mirror routine, swapping max for min
4. Float: what it measures and how to find every critical path
5. Fully worked example: the nine-activity studio build
6. Crashing: spend money only where it shortens the longest path
7. Justification wording that examiners actually mark
