The Six Sigma performance methodology grew from the quality programmes of the 1980s. First used by Motorola, the programme's reputation increased when it powered General Electric to new growth later in the decade. It is the most rigorous of the available improvement programmes. It employs a "breakthrough strategy" designed to target high value projects within a company as quickly as possible, initially through the selection, training and deployment of "black belts" - improvement project team leaders who are trained in the use of Six Sigma's statistical and management tools.

Six Sigma was introduced to Comalco in November 2001. Andrew Rosengren was charged with its implementation as Six Sigma champion. "The level of commitment Six Sigma needed meant it had to be driven from the very top," Rosengren observes.

"Sam put his stamp on the programme and he takes every opportunity to reinforce the message that Six Sigma is important, it is delivering sizeable dollars, and it is here to stay. This ensures that it will not become just another passing management fad as it did in a few companies where it was less wholeheartedly embraced."

Six Sigma's comprehensive approach marks it as different and more powerful than other methodologies reviewed by Comalco. Its scientific precision and discipline appealed to engineers and technologists alike. Senior management launched the programme with an orientation visit to Six Sigma sites in the US, selection of the consultant Six Sigma Qaltec and personal training.
