Comparative Analysis of TQM and CMMI

It is the consensus of people that improving product quality by improving management, but the management standards adopted in different fields are not the same, which is easy to be confused. As to the current status of different quality management standards and methods used in different business areas, this paper analyzes the development history of the general quality management system in the production field and the core concept of total quality management(TQM), compares it with the CMMI standard of quality management in the system development field, analyzes each other's strengths and weaknesses, and proposes suggestions for improving the deficiencies of CMMI. Finally, the relationship between TQM, CMMI and system engineering (SE) is analyzed, and concludes that the integration with model-based system engineering(MBSE) will be the new direction of CMMI's future development.
