A "cone of uncertainty" can be used to do what? (choose the best answer)

B. Rapidly identify and prioritize all uncertainties.
C. Determine whether to cut quality, similar to the "Iron Triangle" of project management.
D. Represent the relative level of difficulty for predicting the velocity of individual team members.

Answer: A

Cone of Uncertainty describes the evolution of the amount of best case uncertainty during a project. At the beginning of a project, comparatively little is known about the product or work results, and so estimates are subject to large uncertainty. As more research and development is done, more information is learned about the project, and the uncertainty then tends to decrease, reaching 0% when all residual risk has been terminated or transferred
