Abstract

In this paper, we propose to apply artifact mining in a global development environment to support measurement based process management and improvement, such as SEI/CMMI's GQ(I)M and Six Sigma's DMAIC. CMM has its origins in managing large software projects for the government and emphasizes achieving expected outcomes. In GQM, organizational goals are identified. The appropriate questions with corresponding measurements are defined and collected. Six Sigma has its origins in manufacturing and emphasizes reducing cost and defects. In DMAIC, a major component of a Six Sigma approach, sources of waste are identified. Then changes are made in the process to reduce effort and increase the quality of the product produced. GQM and Six Sigma are complementary. Both approaches rely heavily on the measurement of input and output metrics. Mining development artifacts can provide usable metrics for the application of DMAIC and GQM in the software domain.
