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Nothing screams for Six Sigma more than outdated systems and processes bogged down by red tape and bureaucracy.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?
And like any toolbox, each individual tool needs to be applied correctly when the right situation warrants it, and some tools are needed more frequently and can be applied more easily than others.
I build systems that have to operate on the edge of space.
There is only so much skrimping you can do on something that has to operate in those conditions.
Bean counters think they have the answer to every thing.
