A project sponsor is adamant that a complex project must be completed within 12 months. Based on lessons learned from previous projects of this type, the project manager believes that the project cann

A Pareto Diagram is a bar chart showing the frequency of causes for problems, ordered from most to least frequent, used for identifying the most significant problems.

A Decision tree is a diagram that models possible decision paths and their outcomes, used for making choices under uncertainty, not for simulating project completion times.

Monte Carlo analysis is a simulation technique that performs a large number of iterations to calculate a range of possible outcomes and their probabilities. This makes it ideal for showing the likelihood of completing a project by a specific date, considering the variability in task durations and other project uncertainties.

Quantitative risk analysis is a process that numerically analyzes the effect of identified risks on overall project objectives, and while Monte Carlo is a tool used within this process, it is not the process itself.
