Three-Point (PERT) Estimate

Estimate a task’s duration or cost using optimistic, most likely and pessimistic values.

Risk Expected Monetary Value (EMV)

EMV = probability × impact. Use a negative impact for threats and a positive impact for opportunities.

Communication Channels

Channels = n × (n − 1) ÷ 2, where n is the number of stakeholders, including the project manager.
