In Capability Maturity Model Integrated (CMMI), Lead Appraiser (LA) evaluates the processes of one company according to qualitative sources such as instrument, interview and document through direct artifacts, indirect artifacts and affirmation. Due to the subjective measurement and non-quantitative expression of LAs, this paper proposes a fuzzy quantitative integrated metric model (FQIMM) that combines Quantitative Software Metrics Set (QSMS), linguistic variables, interval of confidence and a new fuzzy number ranking method. It can help software companies to evaluate on quantitative approach and then know the status by their self more quickly and effectively. Moreover, a CMMI appraisal support system (CMMI-ASS) is developed to help self-assessment software companies to accomplish the appraisal process, which integrates a fuzzy number ranking method to rank the final result.
