University of Southern California Center for Systems and Software Engineering COCOMO II Status and COCOMO III Plans Baseline COCOMO II calibrated to 161 project data points –Pred (20%; 30%) = (63%; 70%) general; (75%;80%) local Added 149 data points 2000-2009 –Pred (30%) < 40% general; some sources ~70-80% local –Some improvement with added variables (year; domain; agility) But some data-source mismatches unexplainable Vu Nguyen analysis of full dataset suggests further adjusting –Rating scales for experience, tools, reliability Proposed approach for COCOMO III –Explore models for unexplained existing sources or drop –Try added variables for mostly-general fit to existing data –Obtain more data to validate results 1/13/2014© USC-CSSE2
