Applications of PERT: PERT is best suited to which of the following categories of projects?

Introduction / Context:
PERT excels in environments with uncertain task durations and complex interdependencies. It supports probabilistic scheduling and risk-informed decisions across diverse projects.

Given Data / Assumptions:

• Activities have variable durations.
• Network precedence is known or can be estimated.
• Leadership requires likely completion times and risk estimates.

Concept / Approach:
By using three-time estimates for each activity, PERT calculates expected times and variances, then assesses the critical path and completion probabilities. This fits R&D, campaigns, and installations where uncertainty is high.

Step-by-Step Solution:

Verification / Alternative check:
Examples from R&D and marketing launches often use PERT to handle uncertainty and communicate schedule confidence.

Why Other Options Are Wrong:
Each single domain is valid; the inclusive answer acknowledges PERT’s cross-domain suitability under uncertainty.

Common Pitfalls:
Forgetting to update estimates as information improves; misidentifying dependencies.

Final Answer:

All of these
