Critical Path Method (CPM) commonly applies single-point deterministic activity durations to build the network, determine early/late dates, and identify the path with zero total float. Program Evaluation and Review Technique (PERT) models uncertainty with three-point estimates using a weighted average (often (O + 4M + P)/6) to derive expected durations and sometimes variance. While modern tools blend approaches, conceptually PERT emphasizes stochastic modeling of time risk, whereas CPM emphasizes deterministic planning and critical path analysis. Option A reverses roles. Option B misstates CPM’s focus; resource leveling is a separate process that can be applied to any network. Option D is a false specialization; both techniques are domain-agnostic. CAPM candidates should also understand that once expected durations are calculated (PERT), the resulting network can be analyzed similarly to CPM. Further, teams may perform quantitative schedule risk analysis (e.g., Monte Carlo) on the network to generate probabilistic completion dates and confidence levels for milestones.
