The military is not a manufacturing business.
To treat it as one is a mistake IMHO.
No offense intended, but once again, you are demonstrating ignorance of what Six Sigma is. It is NOT exclusively a manufacturing tool, it only has that reputation because it has been primarily USED by manufacturing companies.
Six Sigma is a PROCESS IMPROVEMENT TOOL that can be used with great effectiveness on any measurable process. For example, Six Sigma is one of the primary tools used by the Ritz-Carlton to help them achieve world-class customer service.
Nothing screams for Six Sigma more than outdated systems and processes bogged down by red tape and bureaucracy. Can you tell me with a straight face that the military doesn't have any of that?
