【Abstract】 Software project management and control depend upon realistic estimation to provide the data from which a project may be costed and progress monitored.In this paper,some models which are used for the software project estimation and control,like Norden/Putname model,the dynamic lifecycle model based on the Rayleigh curve as well as the difficulty and feasibility of the project are discussed.更多还原
