The Problem Bank of America Faced in 2001
Bank of America had tried quality improvement before 2001.
Those earlier efforts produced little lasting change. Quality leader Milton Jones later described the issue clearly. The programs lacked systematic implementation. They often lacked executive support too.
As a result, many employees dismissed quality initiatives as another “Flavor of the Month.” Error-prone processes continued to cost the company money. Rework consumed time and resources across departments.
Then, in 2001, Kenneth D. Lewis became CEO. He made a decisive shift in strategy.
Lewis announced a move from growth-by-acquisition to organic growth. To grow organically, the bank needed loyal customers. To earn loyal customers, the bank needed far better processes.
Lewis chose Six Sigma as his methodology. He hired Chuck Goslee as the bank’s first-ever quality executive. Goslee reported directly to Lewis.
That reporting line sent a clear message across the organization.
How the CEO Led From the Front
Lewis did not delegate Six Sigma to a support function and move on.
He took the first Green Belt project in the company himself. The project targeted customer complaints elevated to the executive level. The bank was receiving 20,000 such complaints annually. The actual and potential financial losses ran into the millions of dollars.
Lewis described his reasons at the 2004 ASQ conference. He wanted to send a clear message about executive support. He wanted a working command of Six Sigma tools. And he wanted to solve a real problem that was already on his desk.
The project produced measurable results. Customer delight on the issue doubled. The project generated a financial impact of more than $2 million.
Lewis also required every member of his executive leadership team to complete Green Belt training. By 2004, every direct report had Green Belt certification. About 95% of leaders in the next two levels had completed their training as well.
Goslee established a single enterprise-wide customer delight metric. This replaced fragmented product- and channel-specific measures. The bank set a stretch goal of 90% customer delight. Cross-functional teams began working on projects tied directly to that goal.

The Deployment Strategy: Internal Training Plus External Talent
Bank of America faced a common challenge when scaling Six Sigma beyond manufacturing.
There were not enough Master Black Belts (MBBs) and Black Belts (BBs) internally. The bank addressed this with a two-track approach.
Internally, the bank trained Green Belts broadly across the organization. Externally, it recruited experienced MBBs and BBs from proven Six Sigma organizations. Motorola and GE were among the sources of that external talent.
This combination seeded a quality culture quickly. It also gave the program the technical depth it needed from day one.
All of Lewis’s direct reports conducted their own Green Belt projects. The executive project list included the following:
- Reducing customer complaints elevated to the executive level
- Increasing new-hire productivity through better training programs
- Eliminating significant travel expenses across the organization
- Improving fraud detection and prevention at banking centers
- Increasing collections by reducing abandoned inbound calls
- Improving customer referrals generated from tellers
- Improving credit card sales performance
Each project addressed a real business problem. Each produced measurable results.
By 2003, Bank of America had trained more than 10,000 Champions, MBBs, BBs, and GBs. More than 100 senior leadership positions required Black Belt certification as a prerequisite.
The Results: What Six Sigma Delivered at Bank of America
The outcomes Bank of America achieved are documented in the Lasater Institute case study. That study draws directly on CEO Lewis’s public statements and internal quality reports from Jones.
Here are the verified results from the period 2001 to 2003:
- Missing items on customer statements fell by 70%
- Defects across electronic channels, including ATMs and online banking, dropped by 88%
- Non-credit losses, including fraud, declined by 28% on a per-account basis
- Same-day payment processing improved by 22%
- Deposit processing accuracy improved by 35%
Customer outcomes:
- The enterprise-wide customer delight metric rose 25% across the company by 2003
- The number of accounts grew by more than one million in 2003 alone
Mortgage processing:
- One project on mortgage applications reduced average cycle time by 15 days
Financial impact:
- Cumulative financial benefits exceeded $2 billion by the end of 2003
In Bank of America’s official SEC Form 8-K press release, dated April 15, 2002, CEO Lewis stated: “Our results clearly demonstrate the progress we are making in the execution of our customer-focused strategy, the enhancements generated from our Six Sigma program and the improvement in our risk management processes.”
That statement was made in a filing to the US Securities and Exchange Commission. It carries full legal standing as an official corporate disclosure.
What Happened Next: Six Sigma Drives Revenue Growth
The first phase of Bank of America’s Six Sigma program focused on cost savings and defect reduction.
Lewis then asked Milton Jones to lead the next phase. Jones succeeded Chuck Goslee in April 2003.
The mandate shifted. Six Sigma would now drive top-line revenue growth as well. The methodology extended across the entire value chain. That included suppliers and the sales force.
Lewis and Jones required key vendors to apply Six Sigma too. Vendors participated in Bank of America’s training program. This extended the quality culture beyond the bank’s own operations.
Individual revenue-generating projects from this phase included:
- A project to improve lockbox deposit availability: $5 million in revenue
- A project to retain customers who move within the bank’s geographic footprint: $7.8 million in revenue
- A project to improve customer referrals from tellers: $10.7 million in revenue
- A project to improve results from new sales hires: $2 million in revenue
- A project to reduce identity theft through account takeovers: $6.6 million in loss reduction
These figures are drawn from a published project list on iSixSigma, which sourced them from Bank of America’s internal quality reporting.
Lewis also applied Six Sigma to the integration of FleetBoston Financial. Bank of America announced that merger in October 2003. Lewis stated at the 2004 ASQ conference that Six Sigma would be a key to unlocking the full value of the merger. He described it as the first time Six Sigma had been used to execute the merger of major financial institutions.
What Made the Program Work
Milton Jones summarized the keys to success directly. He stated:
“Quality and Six Sigma have become part of the culture at Bank of America, thanks to senior commitment, a robust internal training program, aggressive and ongoing external recruiting, and results that excite everyone in our company.”
The Lasater Institute case study identifies four specific factors behind the program’s success:
- Strong leadership from the top. Lewis personally completed Green Belt training. He required his entire leadership team to do the same. Skeptics changed their view when they saw the CEO and his executives take it seriously.
- Rigorous deployment structure. The bank combined broad internal training with targeted external hiring of experienced MBBs and BBs. This gave the program both scale and technical depth.
- A single enterprise metric. Replacing fragmented measures with one company-wide customer delight metric gave teams a clear, shared target to work toward.
- Revenue focus, not just cost focus. The program expanded from cost savings into revenue generation. That broadened its business case and sustained executive attention over time.
What This Means for Your Organization
Bank of America was not a manufacturer. It was one of the largest financial institutions in the United States. Six Sigma produced the same magnitude of benefits there as it had in manufacturing.
The methodology works because the underlying structure is universal. Every bank, hospital, logistics company, or professional services firm has processes. Every process has variation. Variation creates errors, costs, and dissatisfied customers.
The DMAIC framework gives any team the tools to find those problems, measure them, identify their root causes, and fix them permanently.
At Six Sigma Development Solutions, we deliver Six Sigma training in three formats. We offer onsite programs for organizations training teams together. We offer live virtual sessions for distributed teams. We also offer online self-paced programs for professionals who need flexibility.
Every format teaches the same rigorous DMAIC methodology that Bank of America used to generate $2 billion in benefits. We teach it in a way that applies directly to your industry and your processes.
If Bank of America could transform error rates, cycle times, fraud losses, and customer satisfaction using Six Sigma, the methodology can work for your organization too.
