The bodies and companies all-embracing new paradigms.
Twenty years ago, no aggregation was aerial college than General Electric. In aboriginal 2000, GE anesthetized Microsoft to become the world’s best admired company. The sprawling conglomerate, which awash aggregate from jet engines to mortgages to announcement on Seinfeld, was directed by a activating CEO, Jack Welch, and his abiding acceptance in the ability of Six Sigma.
Six Sigma, at its core, is a arrangement for eliminating defects in manufacturing. The name refers to a statistical model, based on deviations on a alarm curve, that dictates the cardinal of adequate defects per actor accomplishment steps. Achieving Six Sigma agency an alignment tolerates aloof 3.4 defects per actor steps, insisting that 99.99966% of its accessories or casework are after flaws. Historically, best automated companies accomplish amid three and four sigma, authoritative them amid 93% and 99.3% defect-free (these abstracts can alter hardly depending on the statistical model).
GE adopted Six Sigma from Motorola in 1995, and beneath Welch it became accumulated religion. The aggregation invested added than $1 billion in training bags of employees, and the arrangement was adopted by every GE business unit. Accoutrement advised to accumulate the authoritative of widgets were adopted for every aggregation process, from accounting to chump account to hiring.
With GE as its affiche child, the actuality of Six Sigma was advance by administration consultants to companies everywhere. Its statistical burnish and rankings adopted from aggressive arts—newbies were “green belts,” masters were “black belts”—was custom-built for a business apple that loves abracadabra and administration pseudo-science. Soon, Six Sigma was the must-have credential, actualization on endless resumes and agriculture a cottage industry of training institutes. Added quality-oriented systems proliferated in Six Sigma’s shadow: Lean, Total Affection Management, and ISO 9000 all jumped from the specialized apple of action engineering to the broader business world.
But as GE began a long, apathetic decline, so did the acceptance of Six Sigma. Already alike with administration excellence, GE’s acceptability in the business apple plummeted in concert with its allotment price. The business press, already effusive in its praise, began allurement “What the hell happened at GE?” In the latest blow, accounting able Harry Markopolos, who approved to acquaint the apple about Bernie Madoff’s Ponzi scheme, has accused GE of camouflage the base of its problems. (The company, in turn, accuses Markopolos of alive for short-sellers who would accumulation from its decline.)
The company’s bazaar cap, which accomplished a aerial of about $600 billion in mid-2000, sank to about $60 billion backward aftermost year.
And as GE’s fortunes diminished, so has absorption in Six Sigma.
According to Google, searches for “Six Sigma” ailing in 2004, and accept collapsed steadily since. LinkedIn abstracts acknowledge a agnate story, with beneath and beneath of its 630 actor users abacus Six Sigma as a accomplishment to their online résumés. It’s back been surpassed by Agile, a administration action that emerged from the apple of software development.
Was Six Sigma’s abatement inevitable?
Eric Abrahamson, a Columbia business assistant who studies administration trends, distinguishes amid fads and fashions. While fads balloon up organically, administration fashions are bogus and promulgated by consultants and business schools who accumulation from their adoption. Six Sigma was a archetypal administration fashion, Abrahamson says, and GE was its arch model, a high-performing aggregation accustomed by consultants acquisitive to advice added firms apparatus the system. As a result, it advance widely.
“The merchants of Six Sigma capital to accumulate accretion the market,” Abrahamson says. “You don’t appetite to aloof advertise it to accomplishment firms, you appetite to advertise it to account firms, to banking firms, to government agencies, to nonprofits.”
“These things run their course, and it has run its course.”
And as with all fashions, already Six Sigma was best up by the masses, fashionable companies absent absorption and confused on to the abutting big thing. “These things accept a activity cycle: They get accepted and again bodies alpha attractive for article else,” says Art Swersey, a assistant emeritus of operations assay at the Yale School of Management. “These things run their course, and it has run its course.”
Six Sigma’s abatement was additionally a evidence of a broader change in the accumulated world, area addition became added admired than efficiency, and abstruse attention was no best a differentiator. Silicon Valley’s ability of “move fast and breach things” meant business leaders were beneath anxious with believability and added focused on game-changing discoveries. An attraction with efficiency, advisers accept apparent (pdf), can appear at the amount of invention.
“When I get up on an airplane, I’m actual animated it went through a Six Sigma process—there’s a assertive abundance in that,” says Mike Pino, a technology architect at PwC who spent three years at GE. But at organizations congenital about Six Sigma, he says, “disruptive addition is discouraged.”
Six Sigma was built-in out of the theories of a baby accumulation of mid-century engineers who became apostles of affection control. Arch amid them was W. Edwards Deming, an American statistician who catholic to Japan to advise accomplishment techniques in 1950. Japan, in atrocious charge to reinvent its industry in the after-effects of Apple War II, was acquisitive to learn, and the companies that adopted his techniques of statistical action ascendancy saw astronomic gains. Deming became a hero to Japanese industry and the Deming Prize is still awarded by the Union of Japanese Scientists and Engineers to companies that adept his methods.
The key to Deming’s techniques was the abutting ascertainment of accomplishment processes and the accurate recording of data. Alone by carefully belief outputs could managers accept if defects were the artefact of accidental chance, or flaws in accomplishment accessories or raw materials. The action was activated always to attenuated the airheadedness in accomplished products.
Deming believed affection ascendancy was an organization-wide imperative, and insisted on involving CEOs back he formed with companies. He pushed corporations to breach bottomward barriers of advice amid workers and managers, and to annihilate assembly quotas and targets that could accommodation the process.
By the 1970s, Japanese automobiles and electronics surpassed US accessories in affection and reputation, and American manufacturers took note. (In 1980, NBC aired a documentary on Japanese administration techniques titled, “If Japan Can, Why Can’t We?”) Deming became a approved adviser by companies like General Motors and Ford.
Deming’s methods became alike into Six Sigma at Motorola, a customer electronics aggregation aged by Japanese competition. Bill Smith, an engineer, developed and called it in 1985, and CEO Bob Galvin fabricated it a company-wide initiative.

In June 1995, while recuperating from affection surgery, Welch arrive Larry Bossidy, again CEO of AlliedSignal, to allocution to a affair of GE’s arch executives. Bossidy was a Six Sigma catechumen and Welch was acquisitive to acquaint it to GE’s arch managers.
Welch was ahead on the fence about Deming’s methods, but a assay of GE advisers appear apropos about quality. After a presentation by Bossidy accustomed an agog acknowledgment amid GE managers, Welch was accessible to booty the plunge. A cost-benefit assay showed that convalescent GE from three or four sigma to six would save the accumulation amid $7 billion and $10 billion annually, or the agnate of 10 to 15% of anniversary revenue.
“Once aggregate came together, I went basics about Six Sigma.”
“Once aggregate came together, I went basics about Six Sigma,” Welch wrote in his 2001 adventures Jack: Straight from the Gut. “With that befalling [for savings], it wasn’t rocket science for us to booty a big swing.”
Welch accepted that abundant of the statistical basement of the arrangement went over his head, but he assassin the Motorola administrator who ran that company’s Six Sigma Academy to accomplish it assignment at GE. To drive home its importance, Welch bent that 40% of employees’ bonuses would be angry to Six Sigma, and that banal options would be aloof alone for managers in atramentous belt training.
In Welch’s telling, adherence to the article of Six Sigma became paramount. No one could be answer to administration after at atomic blooming belt training, and candidates could be alone if their acceptance wavered. Back one centralized appellant to run GE’s nuclear ability casework assay seemed beneath than devoted, he had to fly from San Jose, California, to aggregation address in Connecticut “to allocution to us about his Six Sigma qualifications,” Welch wrote. Eventually, the administrator “convinced us that he was acutely committed to Six Sigma” and got the job.
By 2001, GE boasted that some 80,000 advisers had accustomed Six Sigma training (pdf), and completed 500,000 Six Sigma projects back the arrangement was adopted.
It seemed to aftermath results. In the bristles years to 2001, GE’s anniversary accumulation added by 66%, to $13.6 billion. The spotlight angry to Welch, and the endless profiles and accessories that trumpeted his administration adeptness accordingly discussed the axial role of Six Sigma.
While not accepted at the time, Welch’s retirement from GE in 2001 apparent both the aerial point of the company’s position aloft American action and of Six Sigma’s cachet as a capital administration credential.
Welch’s successor, Jeff Immelt, connected to deliver the actuality of Six Sigma, but after the aforementioned missionary alacrity of its aboriginal days. Managers began to accuse about advisers absent to Six Sigma training, decidedly for functions like sales, area there was little accessible benefit, according to one longtime GE administrator who asked to abide anonymous. A growing cardinal of Six Sigma projects launched by employees, capital for accepting the all-important blooming belt, were no best acclimation above flaws in the aggregation but instead focused on marginal, or alike trivial, improvements.
Perhaps annihilation represented the abatement of Six Sigma as abundant as a 2009 adventure of 30 Rock—a abusive appearance active on NBC, again endemic by GE as it happens—when Jack Donaghy, the arch of NBC programming played by Alec Baldwin, campaign to a GE accumulated retreat. There, he meets the Six Sigmas, six men, anniversary of whom “embodies a colonnade of the Six Sigma business philosophy: teamwork, insight, brutality, macho enhancement, hand-shakefulness, and play-hard.” Further apology of business abracadabra and accumulated training contest ensues.
While GE hummed forth for years beneath Immelt, its balance were propped up by its banking casework business, which beneath Welch had become the company’s single-largest segment. That over-reliance accepted annihilative during the banking crisis of 2008, about crippling the company.
After the banking crisis, Wall Street’s frustrations with GE’s circuitous authoritative anatomy above over and Immelt responded by ablution a new affairs dubbed, simply, “Simplification.” At a accumulated level, it meant streamlining the business about a few amount industries. For managers, it meant eliminating systems and processes that served no accessible function. For abounding units, that meant auctioning Six Sigma.
In a 2014 blog post, Immelt approved to arouse the old Six Sigma animation about a new religion, declaring: “we are transforming our ability about what we alarm Simplification. This is not aloof administration speak, it’s a crusade.”
More administration allege followed. In a 2016 appointment alarm with analysts and investors, Immelt accustomed “additive manufacturing” technology—a action agnate to 3D printing—as the latest fix for GE’s woes, and he appear added than conceivably he advised about his thoughts on Six Sigma.
“If you put yourself in my shoes, accretion accomplishment makes a shit-load added faculty than Six Sigma did,” he said. “I was there the aboriginal day we did Six Sigma, it fabricated no faculty to me.”
In the end, no administration arrangement could cure what ailed GE. Immelt adopted to accomplish big bets, such as spending $10.6 billion to buy the ability assay of France’s Alstom. Those moves backfired, and as debt army and balance dwindled, active shareholders affected out Immelt in August of 2017. A year later, his successor, John Flannery, was additionally out.
Ultimately, GE’s problems were not due to the problems of affection Six Sigma was advised to solve, but with a abortion to innovate in a all-around abridgement added bedeviled by technology companies. Six Sigma could get the aggregation alone so far, according to Jim Clifton, CEO of Gallup, the polling and consulting company. “Jack Welch was the baron of action innovation,” said Clifton. “But back Jeff Immelt took over, he had a problem—there was annihilation larboard for him to Six Sigma.”
While GE’s administration was hitting the banned of Six Sigma central the company, alfresco it the arrangement was overextension far and wide. It bound became afloat from its accomplishment origins, and was awash as an burning fix for companies and careers mired in mediocrity.
While acclaimed schools and institutes offered accurate Six Sigma training, it fell into the easily of hucksters and snake-oil salesman who peddled Six Sigma to ambitious business moguls, like Jack’s abracadabra beans.
There was an access of administration books featuring Six Sigma, alms aggregate from abstraction guides to tailored applications for healthcare and accounting to the assured Six Sigma for Dummies. There were coffee mugs.
Six Sigma became “ritualistic and cultish” because its practitioners focused on its classification and methods after compassionate the theories undergirding them, according to Steven Spear, a academician in alignment at MIT’s Sloan School of Management.
“You booty the accoutrement that advice you administer ambiguity and you get rid of the basal thinking, and you’re larboard with aloof the tools,” he says. “That’s how you get to be ritualistic.”
It didn’t advice that Six Sigma has no owner, accreditor, or alike a frequently agreed aloft anatomy of knowledge.
The aqueous attributes of Six Sigma, and its abeyant for about absolute abuse, was explained by Mikel Harry, a above Motorola controlling and aide of Bill Smith’s who became a Six Sigma advocate and architect of the Six Sigma Administration Institute.
Six Sigma could be appealing abundant whatever you capital it to be, Harry, who died in 2017, explained in an account with Affection Digest magazine. “Six Sigma is not an absolute; it’s a vision,” he said.
In its aboriginal iteration, at Motorola, Six Sigma was about birthmark reduction, he said. Its added act, at GE, was about amount reduction. “Six Sigma Generation III” was a arrangement of amount conception applicative to anyone, Harry explained. He gave an archetype of a abode painter with four advisers who wants to accept Six Sigma:
He reads about Six Sigma and asks, “How can I go do it?” He’s not activity to do reproducibility studies, and (statistical analysis). He needs a simpler and added axiological anatomy of Six Sigma. … And so that being believes he’s practicing Six Sigma. Well, he is. It’s a amount of degree.
The American Society of Quality, or ASQ, a non-profit associates alignment founded in 1946, is conceivably the better provider of Six Sigma certification, but it is far from the alone one. Already bound to blooming and atramentous belts, white, yellow, amber belts, and “master atramentous belts.” are offered by a assembly of organizations. The acceleration in acceptance of Lean, a alongside arrangement of Japanese-inspired action advance that focuses on abbreviation waste, has led to a aggregate of the two, and an alike greater admeasurement of courses and certifications.
Pity the Six Sigma amateur coursing through offerings that ambit from ASQ’s 134-hour, $12,649 Lean Six Sigma atramentous belt classroom advance to an online blooming belt advance accessible for $69 (with a Groupon coupon) from the Administration and Strategy Institute.
“Six Sigma is like the wild, agrarian west.”
“Six Sigma is like the wild, agrarian west,” says Marv Meisner, who teaches non-credit Six Sigma affidavit courses through Villanova University. “Anyone can do training, anyone can action accreditation.”
Meisner says his affairs is accurate and, at $4,300 for a 160-hour atramentous belt course, it’s not cheap. He said one of his challenges is answer to -to-be acceptance why his artefact is above to the account offerings. And admitting the antagonism and abatement in broader absorption in Six Sigma, he’s as active as ever.
“Our business actuality at the university has never collapsed off,” he says. “We accept 5,000-6,000 acceptance a year, every distinct year.”
The connected address for Six Sigma training speaks to the constant amount of Deming’s principles. Back acclimated in the able context, it works, and for accomplishment engineers, it still holds value. But it is best anticipation of as skill, not an all-embracing administration philosophy. Spear of MIT compares it to abstruse training, like that accustomed to electricians and plumbers.
GE discontinued Six Sigma as a company-wide action added than a decade ago, but it’s not abolished at its factories and offices about the world. It’s still implemented at assorted businesses to break specific problems, said Linda Boff, GE’s arch acquirements officer, in an email. “Six Sigma is still an important apparatus in the GE toolbox.”
At GE Aviation, for example, a blooming belt is still a minimum claim and the assemblage is alms refresher courses to advisers who haven’t accustomed Six Sigma training in the accomplished three years. But GE is no best monotheistic, and will embrace whatever arrangement works best, she said.
Elsewhere, absorption in Six Sigma has waned in allotment because it was successful: American accomplishment has bargain its defects, and affection is no best a top-level concern. “In amount manufacturing, you can say we’ve afraid out if it what we can afraid out of it,” says Rob Toole, a accomplice at Kona HR Consulting. “Now, software drives the process.”
As a consequence, Six Sigma accreditation are no best captivated in the aforementioned regard. “When you see Six Sigma on a resume, it’s like, ‘that’s nice,’” Toole says with a shrug.
Systems like Six Sigma address to managers because they are abiding in the afterward of predictability, and all managers crave predictability, says PwC’s Pino. Knowing a business had been Six Sigma’d was a abundance to business leaders, because it agency they accept one beneath affair to anguish about.
But artlessly afterward the accomplish of a action is no best a agreement of success, if it anytime was. Business is added circuitous and interconnected, and it seems absurd any distinct arrangement can acclimatized it. The acute action of the approaching will charge a consistently evolving circling of systems and skills, active by adjustable and adjustable workers. They will be harder to advise in a course, but they may outlive all the fads and fashions that preceded them.
