How Do CMMI and Six Sigma Actually Work?
CMMI’s discipline specific approach includes systems engineering, acquisition processes and service. All are related to the process infrastructure needed for providing the process backbone for an organization to be success. CMMI makes sure Process Management, Project Management, Engineering and Support are in place so the business organization can meet specific goals. By contrast, Six Sigma diagnoses and characterizes a problem, and then determines how to improve processes analytically and quantitatively. “The two technologies work really well together,” says Jeannine Siviy, senior member of the technical staff at the Carnegie Mellon Software Engineering Institute. “Six Sigma wants you to map out your processes (Process Mapping), but it doesn’t actually tell you what the processes should be. CMMI determines the right processes for an organization to start. However, an organization may have to tailor it or add to it to make it work for them. CMMI provides the process backbone that Six S
