A probabilistic approach to cost estimation

Conclusion: Deterministic1 project budgets do not convey any information about the range of possible outcomes for a project, or the associated risk factors driving the range. The ability to communicate the risk-weighted range of possible project outcomes can lead to much clearer expectations and understanding of project outcomes, especially for project sponsors. Modelling these ranges can be performed with relative ease, using basic Excel add-ins and high-level estimates of risk applied to the components that make up a project2.
