Answer

Mandatory dependencies are inherent to the work or required by contract and cannot be modified by the team.

Question 3

A project scheduler uses a Monte Carlo simulation during schedule risk analysis. The primary output used for decision-making is:

Accepted Answer

A probability distribution of possible project completion dates

Answer

Monte Carlo simulation produces a probability distribution showing the likelihood of completing the project by various dates.

Question 4
