I don’t see any evidence six sigma is making a comeback but magazines like to talk about new ideas rather than just explore what continues. They like to discuss common cause variation as though it were special cause. Six Sigma Makes a Comeback
How sad. Six sigma has always been hampered by a lack of core values (like respect for people, constancy of purpose) and a focus on cost cutting but the direct desire to pursue a deadly disease (short term focus) is sad indication of where some have taken what can be very useful tools.
Six sigma and quality management other efforts can be very useful. But many of the efforts (as many of any management efforts) are executed poorly and do little good and much that is rightly ridiculed.
