Deming was not into the whole six sigma thing, but alot of the principles behind six sigma are in line with the system of profound knowledge. There are others that are not; like the Green belts and Black belts obviously coined from the asian martial arts grading system. This goes against Deming's teaching on Psychology by recognising few as champions as this will be demmoralizing for the others. Now if six sigma agrees that most causes of failure is the socio-emotional issues, then why bring in this grading system? Deming strived to make the world better with his teachings and Six sigma followed, but had too make champions.
Please I need your inputs on this.
