Software Productivity Analysis with CSBSG Data Set

The aim is to report on an initial exploratory statistical analysis of the relationship between software productivity and its influencing factors in China. We analyzed of a data set containing project measurement data which were collected from lots of IT companies in China by China Software Benchmarking Standards Group (CSBSG), established by China Software Process Improvement Network (CSPIN), China.Productivity with its influencing factors was investigated using a exploratory statistical analysis. Only 133 closed projects with high ratings could be used in this investigation. Furthermore, confidentiality and data quality, data filling ratio and sizing method were considered as major issues during our current work and also for future investigation. Overall, we observed that influencing factors - project size, project type and business area - do affect productivity with different level statistical significance. However, no clear evidence can be observed that factors, like maximum team size and programming languages affect productivity. Ongoing analysis of productivity and its influencing factors. Based on current productivity analysis results, comparative analysis between counties and estimation modeling will be investigated in future.
