In this paper, we propose the application CCPM(Critical Chain Project management) approach reflects the productivity of software development as an alternative to overcome the problems of software development project management. The various efforts for a successful project management is underway in most industries and are growing in importance. The CCPM has been successfully applied in the industry can be demonstrated through many examples. However, considering the difficulty chain approach to project productivity in the software development environment is a situation still insufficient research. First, the software size, the characters show that the difference in productivity between the industry from the data of the software development project is evaluated in the FP(Function Point) measurement method to be used for measuring the effort. Data is subject to analysis and secure through a screening process for the project and major industries that meet certain criteria. Since productivity is based on how to present the applications designed to establish a project buffer size difference is considered the application of the project`s production the CCPM method.
