Cone of Uncertainty

Cone of Uncertainty represents the increasing level of precision of effort to realize a project. In the early stage of project, the level of accuracy is low so the error margin is wide. Then they get narrower as the project progress from feasibility to requirements, to concept design, to detail design, to execution and finally is completed.

Application

The understanding of this will help in the evaluation of projects and the level of precision will be according to the progress in the life cycle of the project.

It can be used in all kinds of projects, software, construction and others
