Obtaining an earned value includes storing a simulation version of a project baseline. The project baseline includes tasks that define a project associated with the project baseline. The simulation version is copied to create an operative version of the project baseline. The simulation version is augmented with an additional task such that the simulation version maintains separate baselines for the additional task and for pre-existing tasks. The additional task is mapped from the simulation version to the operative version such that the operative version incorporates the additional task and the pre-existing task into a single baseline. The earned value is obtained for the project using the operative version.
