Theory of PERT/CPM Analysis
Example Problem:
Activity A (Design): a=6, m=8, b=10 days, no predecessors
Activity B (Planning): a=4, m=6, b=8 days, predecessor: A
Activity C (Development): a=10, m=12, b=14 days, predecessor: B
Activity D (Testing): a=3, m=4, b=5 days, predecessor: C
Solution:
Expected Times: A=8, B=6, C=12, D=4 days
Critical Path: A → B → C → D
Project Duration: 30 days
All activities are on the critical path (slack = 0)
