To improve the accuracy rate of software effort estimation,this paper proposed a dynamic effort estimation method.First,it adopted the size based effort estimation model to estimate the effort before project execution according to the linear and nonlinear relationship between effort and size. Secondly,it adjusted the effort based on the new informations obtained during project execution. Finally,it evaluated the estimation method and the estimation results after the project completion. In order to improve the accuracy of estimation,it took the exponential function relationship between effort and schedule as the verification guide for the proposed method. The proposed method looks effort estimation as a task that should be executed throughout the project's whole life cycle. The proposed method provides a simple and effective method for software companies to improve their estimation accuracy,and help them achieve continuous improvement.
