Software size estimation has been long a challenging task over a software development process. This paper presents an approach that uses the function point analysis to estimate program coding and testing effort in a MIS department, which maintains an ERP system with low employee transfer rate. The method first analyzes the historical data using regression analysis, and then builds a software estimation model with elaborated coefficients for related parameters. The estimation model is tested with the remaining set of historical data to evaluate its predict accuracy. It is shown that the size estimation model can be as accurate as about 90% correctness. Thus it is useful not only in company-wide information resource allocation, but also in performance evaluation of software engineers.

The sweeping penetration of the internet into our daily life has greatly encourageed the international exposure of domestic software companies and engendered an unprecedented demand for information. However, the increasing cost of manual labor throughout the world in recent years has caused the labor force in the mainland China and India to exceed that in Taiwan. Therefore, if enterprises still hope to keep applying internal resources to support system software development and maintenance in the future, they should have a plan to request IT (Information Technology) department to promote the cost control as well as effectiveness development software from now on. The purpose of this study is to delve into the IT department¡¦s response to the reform and restructuring within a company and its assimilation of new management strategies to boost efficiency. This research aims to research how one domestic global enterprise learn project management to further improve the quality of internal software development and promote usage effects. It can be observed from this in-depth comparative study that different management methodologies induce a corresponding difference in the efficiency of developing new software, which, in turn, reflects on the reform of the entire department. The methodology of this research is using qualitative case study analysis by designing a questionnaire to interview internal technical specialists from different areas and carrying out two different structures of project management methods to heavily compare and investigate. From this research, we could actually discover that different project management methods could show different levels of promotion and advancement in software development efficiency. When it comes to corporate trainings in software development management or the reform of IT departments, this study may serve as an invaluable index or example for future reference.
