Compression & Resources

Fast-tracking — overlap; rework risk ↑.
Crashing — add cost to shorten the critical path.
Leveling — respect limits; duration may change.
Smoothing — adjust within float; path unchanged.
Rolling wave — progressive elaboration.

PERT, Channels, EMV

PERT: O M P

tₑ = (O + 4M + P)/6 · σ = (P − O)/6 · variance = σ²

Communication Channels — n(n−1)/2
Stakeholders n

EMV — sum(p×impact). One pair per line.

CPM Lab: Forward/Backward Pass

Network: A→B, A→C, B→D, C→D, D→E. Edit durations and compute ES/EF, LS/LF, Float, and the Critical Path.

Step 1 Forward pass: ES = max(EF of predecessors), EF = ES + Dur
Step 2 Backward pass: LF = min(LS of successors), LS = LF − Dur
Step 3 Floats: TF = LS − ES, FF = min(ES of successors) − EF. Critical path has TF = 0.
