要約(英語): OSS (Open Source Software) has made remarkable progress in recent years. In ES (Enterprise Software) development process, also the OSS usage has been increasing steadily, which means the impact of OSS to the society has become greater and greater. However, the quantitative analysis for OSS development has been put no particular importance today. In this research, we study to enhance COCOMO model, commonly used for ES development, in order to clarify the relationship between human resources and development volume of OSS development projects. We chose 50 of Large Scale OSS development Projects from GitHub for our analysis, and obtained such three findings as: 1. In OSS development projects, with some arrangement in measuring man-months volume, we found that power formula of COCOMO model can be applied for expressing the relationship between the development volume and the outputs. 2. As OSS development characteristics, with the increase of development volume, the efficiency for development shows the rising trend. 3. The tendency found above has been identified as not the results of diversion as copying and modifying sources nor cumulative contribution made by variety of small developers.
