Abstract

Method and system for determining estimation variance associated with project planning are provided. In one aspect, information associated with a project is obtained and initial estimations for the tasks in the project are determined using available information. The tasks are performed and actual measurements are obtained from the completed tasks. The actual measurements are used to revise the estimates of the remaining tasks. The revised estimates are used to compute a project level estimate and a variance on that estimate, and to enable better project management.
