Six Sigma was based on groundbreaking work of Dr. Walter Shewhart, between the two world wars at Hawthorne, Il, USA.
Dr. Shewhart was the inventor of modern quality control based on statistics.

Motorola (1986, Bill Smith), GE and other companies found 3σ insufficient for modern, complex products:
With growing numbers of items, production yields go down to fast.

Over time, processes get worse, e.g. by wear and tear of tools between to replacement cycles.
This is sometimes described by allowing a 1.5σ process shift.

A new quality goal was defined:
Further reduce the error level by a factor of ~1/1,000, even including the process shift.

Once the 6σ quality goal of 3.4 DPMO has been achieved, even complex systems will attain a high yield.
Losses from low system quality (“cost of poor quality”, COPQ) will go down.

Six Sigma is “TQM on steroids”.
Lean applies a “pull” approach on production, i.e. it is driven from the output side, not input.

Common caveats shared with the PMBOK Guide:• Some companies have achieved quick wins
through implementations. • One should not expect repetiton in the own
organization. Benefits are rather long-term.
