Identify the correct distinguishing features between Program Evaluation and Review Technique (PERT) and Critical Path Method (CPM): 1. CPM is suited for projects with predictable, repetitive activities, whereas PERT is designed for uncertain, non-repetitive activities. 2. PERT utilizes a deterministic model, relying on a single time estimate for each activity, while CPM uses a probabilistic model. 3. CPM is a dual-purpose method managing both time and cost control, while PERT primarily focuses on planning and control of time. 4. The concept of 'crashing' (shortening project duration with least additional cost) is applicable to PERT but not to CPM.
