There’s a factory in Glenview, Illinois that has been quietly producing something far more valuable than its industrial products. For over four decades, Illinois Tool Works has been manufacturing elite business operators.
The ITW Business Model—built on the company’s trade-secret 80/20 Front-to-Back Process, Customer-Back Innovation, and a Decentralized, Entrepreneurial Culture—has produced a generation of leaders who think differently about business than their peers. They see complexity as the enemy. They use data to separate the vital few from the trivial many. And they execute with a discipline that produces best-in-class margins and returns consistently across economic cycles.
ITW is a Fortune 200 company with approximately 43,000 employees operating in 85 divisions across 57 countries. Their seven industry-leading segments leverage the unique ITW Business Model to deliver solid growth with best-in-class margins. Since 2012, ITW has roughly doubled its Return on Invested Capital from 14% to 28%. Operating margins across individual segments have seen similar expansion. The data doesn’t lie.
But ITW’s most enduring contribution to American business may not be its own financial performance. It may be the alumni network—the executives who learned the 80/20 operating philosophy inside ITW and then carried it into companies, consulting firms, and entire industries beyond Glenview.
This article profiles the 10 most impactful ITW alumni who are transforming business using the principles they learned at one of America’s most consistently excellent manufacturers.
1. E. Scott Santi – Non-Executive Chairman, Illinois Tool Works
The Architect of Modern ITW
Scott Santi joined ITW in 1983 straight from the Kellogg School of Management and spent his entire career inside the company, rising from field sales to CEO by 2012. His four-decade tenure at a single organization is remarkable in an era of serial job-hopping—and it reflects the depth of institutional knowledge that made his transformation of ITW so effective.
Santi’s signature achievement was consolidating ITW’s sprawling structure of approximately 800 divisions into 85 focused business units, each governed by the 80/20 Front-to-Back Process. This wasn’t incremental optimization. It was a structural revolution that forced every division to identify its vital few customers and products, eliminate complexity, and focus resources where they generated the highest returns.
The results were extraordinary. Under Santi’s leadership, ITW’s operating margins expanded dramatically, Return on Invested Capital roughly doubled, and the company returned over $15 billion to shareholders through buybacks and dividends. He retired as CEO at the end of 2023, succeeded by Christopher O’Herlihy, and now serves as Non-Executive Chairman.
Santi’s leadership philosophy—rigorous 80/20 discipline, decentralized accountability, and relentless focus on the vital few—has influenced a generation of ITW leaders and established the operating template that alumni carry with them when they leave.
Transformation Impact: Consolidated ITW from approximately 800 divisions to 85 focused business units. Roughly doubled ROIC from 14% to 28%. Established the modern ITW Business Model as an industry benchmark.
2. John Nichols – The Father of 80/20 at ITW
The Pioneer Who Changed Everything
Every leader on this list traces their operating philosophy back to one man. John Nichols was the CEO of ITW from 1982 to 1995, and under his leadership, 80/20 was introduced into every facet of the organization as a holistic business model.
Nichols didn’t invent the Pareto Principle. The Italian economist Vilfredo Pareto identified the 80/20 distribution pattern over a century ago. But Nichols was the first American CEO to take a statistical observation and transform it into a comprehensive operating system that governed how an entire Fortune 200 company identified customers, designed products, allocated resources, and measured performance.
After leaving ITW, Nichols took the 80/20 philosophy to the Marmon Group (later acquired by Berkshire Hathaway), where he applied the same principles with similar results. His influence extended far beyond the companies he directly led—through the executives he developed, the principles he codified, and the competitive advantages he demonstrated.
It’s not an exaggeration to say that Nichols created a school of management thought. The 80/20 operating philosophy that now drives billions of dollars in business transformation across multiple industries traces directly to the work he did inside ITW over three decades ago.
Transformation Impact: Introduced 80/20 as a comprehensive business operating model at ITW. Created the philosophical foundation that has produced 25+ years of exponential growth. Spawned an entire ecosystem of 80/20 practitioners and consulting firms.
3. Christopher O’Herlihy – President and CEO, Illinois Tool Works
The Torchbearer
Christopher O’Herlihy represents the ultimate validation of ITW’s operating philosophy: a 35-year ITW veteran who rose through the ranks to become President and CEO, succeeding Scott Santi in January 2024.
O’Herlihy joined ITW in 1989 and held roles of increasing responsibility across multiple segments, including Group President within the Polymers & Fluids segment and Group President of the Food Equipment segment worldwide before being elected Executive Vice President and ultimately Vice Chairman.
His elevation to CEO signals that ITW’s board views continuity of the operating philosophy as the company’s most important strategic asset. In an era when boards frequently look outside for CEO candidates, ITW’s consistent promotion from within reflects an institutional conviction that the 80/20 Business Model is best led by executives who have lived it, not executives who need to learn it.
O’Herlihy has launched the Next Phase of ITW’s Enterprise Strategy, with organic growth as the highest priority—an evolution that builds on the operational excellence foundation that the 80/20 process has established.
Transformation Impact: Carrying forward and evolving ITW’s operating model through the next phase of enterprise strategy. Demonstrating the power of internal leadership development rooted in a consistent operating philosophy.
4. David Philippi – CEO, Strategex
The Evangelist
David Philippi is the CEO of Strategex, the consulting firm that has done more than any other organization to spread the 80/20 operating philosophy beyond ITW’s walls.
Strategex was founded in 1993 by David’s father, Peter Philippi, a former Baptist minister who recognized the transformative power of the 80/20 principle. Under David’s leadership, the firm has hired nearly a dozen former ITW executives and deployed them to corporate clients of all sizes—from companies doing $8 million in annual sales to enterprises generating $28 billion.
As David told Crain’s Chicago Business, “People find that once you adopt 80/20 it’s hard to run a company any other way. You can’t unknow it.” That observation captures something fundamental about the 80/20 operating philosophy: once you learn to see your business through the Pareto lens, every decision—pricing, product development, resource allocation, customer prioritization—looks different.
Under David’s leadership, Strategex has built a comprehensive 80/20 Profit & Growth practice that translates the principles ITW developed internally into methodologies that any company can implement. The firm’s work represents the most direct pipeline from ITW’s internal operating knowledge to the broader business world.
Transformation Impact: Scaled ITW’s 80/20 philosophy to hundreds of companies across industries through Strategex’s consulting practice. Built the infrastructure for spreading 80/20 thinking beyond ITW’s walls.
5. Marc Fooksman – VP, Strategex (Former ITW Group President)
The Operator-Turned-Advisor
Marc Fooksman’s career trajectory represents the classic ITW-to-consultant pipeline that has become a powerful force in American manufacturing consulting.
Fooksman joined ITW through acquisition and became one of the early adopters of the 80/20 process. Over the next 25 years, he assumed increasing responsibilities, culminating in roles as General Manager, VP/GM, and Group President. At his peak at ITW, he was responsible for ten business units with over $330 million in revenue on four continents.
His experience spans the full spectrum of 80/20 application—from standard products to custom-engineered solutions—giving him a versatility that few 80/20 practitioners can match. He also has considerable experience in acquisitions and divestitures, understanding how 80/20 applies to the critical M&A decisions that drive portfolio optimization.
Fooksman’s last position at ITW was the 80/20 Director for the Food Equipment Group, a $2 billion segment, where he significantly improved operating income, grew revenue, and reduced working capital requirements. After retiring from ITW in 2014, he joined Strategex as an 80/20 Expert, bringing decades of operational experience directly to client engagements.
Transformation Impact: Applied 80/20 across $330 million in revenue on four continents inside ITW. Now deploying that experience directly to Strategex clients seeking operational transformation.
6. Luis Mateus – Independent Advisor and Global Manufacturing Executive
The Global Operator
Luis Mateus represents the international dimension of ITW’s alumni impact. A globe-trotting veteran senior executive who spent his career at Signode (later acquired by ITW), Mateus rose through increasingly senior positions in Engineering, Sales/Marketing, and General Management to become Group President with full P&L responsibility for multiple global business groups.
During his years at ITW, Mateus directed the building of greenfield facilities in Mexico, Brazil, and China, and expanded manufacturing operations in India. He drove profitable growth by leading the implementation of 80/20 initiatives throughout his businesses, plus identifying, negotiating, and integrating strategic acquisitions and joint ventures across multiple countries.
Mateus holds a Master of Management from Northwestern University and a Mechanical Engineering degree from the Andes University in Bogota, Colombia. His unique combination of engineering discipline, business education, and global operating experience makes him a particularly valuable example of how ITW’s operating philosophy translates across cultures and markets.
His perspective on 80/20 implementation is informed by having done it on nearly every continent—and understanding that while the principles are universal, the implementation must be adapted to local business cultures, labor markets, and regulatory environments.
Transformation Impact: Built and expanded manufacturing operations across Latin America, China, and India using ITW’s 80/20 methodology. Demonstrated the global applicability of the operating philosophy.
7. Bill Canady – CEO, The 80/20 Institute
The Systematizer
Bill Canady deserves recognition for taking the 80/20 operating philosophy that ITW pioneered and building it into a comprehensive, standalone business operating system that any CEO can implement.
Canady has been leading companies to profitable growth for over 30 years, working across a variety of industries and markets focused on industrial and consumer products and services. His Profitable Growth Operating System (PGOS) represents the most complete codification of 80/20 as a turnaround and growth methodology available in the market.
His two books—The 80/20 CEO: Take Command of Your Business in 100 Days and From Panic to Profit—provide step-by-step playbooks that translate the principles of 80/20 into a 100-day implementation timeline. This specificity—turning philosophical principles into time-bound action plans—addresses the implementation gap that causes most business methodologies to remain theoretical.
Canady’s client roster includes PE-sponsored middle-market companies, industrial manufacturers, and service businesses. His endorsements from practitioners across industries—operators who have implemented PGOS and measured the results—validate the methodology’s effectiveness beyond the specific context of ITW.
Transformation Impact: Built the Profitable Growth Operating System into a comprehensive, implementable methodology. Published two books that serve as field manuals for 80/20 implementation.
8. Joe – Co-Creator, 80/20 Profit & Growth Practice at Strategex
The System Builder
After retiring from ITW, Joe joined Strategex in 2008 and collaborated with founder Peter Philippi and CEO David Philippi to create the firm’s 80/20 Profit & Growth practice from the ground up.
Joe’s contribution is foundational. He developed the process, built the team, and acted as lead adviser for Strategex’s 80/20 engagements. He has developed proprietary techniques currently in use by several blue-chip companies—techniques that translate ITW’s internal operating knowledge into methodologies accessible to companies that never had access to ITW’s training infrastructure.
His background—a BS in Chemical Engineering from Northwestern University and an MBA from Lake Forest Graduate School of Management where he was valedictorian—combines analytical rigor with practical business acumen. He taught the capstone Strategic Management course in the MBA program at Edgewood College for nearly a decade, demonstrating his ability to codify operating principles into teachable frameworks.
Joe is fluent in French and conversational in Spanish, and is highly regarded as a public speaker, teacher, and executive coach. His ability to translate complex operating principles into clear, actionable guidance has been instrumental in Strategex’s success.
Transformation Impact: Co-created Strategex’s 80/20 Profit & Growth practice. Developed proprietary techniques used by blue-chip companies worldwide. Built the team and infrastructure for scaling ITW’s philosophy.
9. Jenn – VP of Strategy, Strategex (Former ITW Division Leader)
The Complexity Killer
Jenn spent the first decade of her career with Illinois Tool Works, holding progressive business leadership roles across several divisions with functional responsibility for sales, marketing, product management, operations, and corporate strategy.
Her experience during the consolidation of multiple ITW operating units gave her firsthand exposure to the most transformative application of 80/20: business segmentation and simplification. She led the segmentation of businesses into focused markets and products, guided value proposition definition, developed growth strategies, restructured commercial organizations, and built product management functions.
Using 80/20, Jenn eliminated complexity through customer and product line simplification—resulting in cost reduction, bottom-line growth, and improved satisfaction of top customers. This combination of outcomes—simultaneously reducing costs AND improving customer satisfaction—is the hallmark of properly implemented 80/20. It’s not about cutting for the sake of cutting. It’s about focusing resources on the customers and products that matter most.
Her specialization in strategy creation and execution makes her a particularly valuable resource for companies that understand 80/20 conceptually but struggle to translate it into actionable strategic plans with measurable outcomes.
Transformation Impact: Led complexity reduction and business segmentation during ITW consolidation. Now helps Strategex clients implement the same strategy creation and execution discipline.
10. Michael Larsen – Senior Vice President and CFO, Illinois Tool Works
The Financial Architect
Michael Larsen serves as Senior Vice President and Chief Financial Officer of ITW, bringing an important external perspective to the company’s operating philosophy.
Unlike most executives on this list, Larsen didn’t spend his entire career at ITW. He joined in 2013 after serving as President, CEO, and CFO of Gardner Denver. His experience leading a company outside of ITW before joining gave him a unique ability to see the 80/20 operating model with fresh eyes—and to articulate its financial impact in terms that investors, analysts, and boards immediately understand.
Larsen’s contributions to ITW’s financial architecture—the capital allocation framework, the shareholder return strategy, and the financial communication of the operating model’s results—have been instrumental in translating operational excellence into shareholder value. Under his financial stewardship, ITW has maintained its commitment to returning capital to shareholders while investing in the organic growth initiatives that drive long-term value creation.
His ability to bridge operational excellence and financial performance makes him a valuable example of how the ITW model translates into the language that capital markets speak.
Transformation Impact: Bridges operational excellence with financial performance and capital markets communication. Contributes external perspective to ITW’s continuously evolving operating model.
The ITW Operating Philosophy That Built an Army
The ITW Business Model is comprised of three elements that, taken together, form one of the most powerful operating philosophies in American manufacturing.
ITW’s 80/20 Front-to-Back Process is a unique set of proprietary tools and methodologies that divisions use to maximize performance for their largest and most profitable customers while minimizing the costs and complexity associated with serving small customers.
Customer-Back Innovation starts with the customer’s needs and works backward to product development—the opposite of the R&D-driven innovation model that most companies follow.
And the Decentralized, Entrepreneurial Culture gives individual divisions autonomy to operate their businesses, make decisions, and respond to their markets with the speed and flexibility of a small company backed by the resources of a Fortune 200 enterprise.
What makes this model uniquely powerful is that it’s not just a strategy. It’s a way of thinking. ITW people see business through a specific lens—one that identifies the vital few, eliminates the trivial many, and focuses relentlessly on creating value for the customers who matter most. Once that lens is internalized, it never goes away. That’s why ITW alumni are so effective wherever they go.
Why ITW Alumni Are So Effective
There’s something distinctive about executives who learned business inside the ITW system. They share several characteristics that set them apart.
They think in Pareto distributions rather than averages. While most executives look at aggregate revenue and average margins, ITW-trained leaders immediately segment everything—customers, products, processes, activities—into the vital few and the trivial many. This analytical instinct produces faster diagnosis and more decisive action.
They have an allergic reaction to complexity. ITW’s culture teaches that complexity is the enemy of profitability. Alumni carry this conviction into every organization they touch, instinctively identifying and eliminating the unnecessary processes, products, and customer relationships that drain resources without generating proportional returns.
They default to action over analysis. ITW’s decentralized culture creates leaders who are comfortable making decisions with imperfect information and adjusting course based on results. This bias for action—combined with 80/20 analytical discipline—produces a distinctive operating style that is both analytical and decisive.
They think like owners, not managers. ITW’s structure gives division leaders full P&L responsibility, creating a general management mindset that is increasingly rare in corporate America. Alumni carry this ownership mentality wherever they go, thinking about capital allocation, return on investment, and long-term value creation rather than just functional optimization.
The 80/20 Network Effect
What’s remarkable about ITW’s alumni impact is the network effect it has created. ITW alumni at Strategex train consultants who deploy 80/20 to client companies. Those client companies develop internal leaders who carry the philosophy to their next organizations. Authors like Bill Canady codify the principles into books and frameworks that reach audiences far beyond any consulting engagement.
The result is an expanding ecosystem of 80/20 practitioners who trace their operating philosophy back to a single source: the work John Nichols began at ITW in the 1980s. This network effect means that ITW’s influence on American business is orders of magnitude larger than what its own market capitalization would suggest.
What ITW’s Alumni Legacy Teaches Every Organization
The ITW story isn’t just about one company’s success. It’s about the power of a clear, consistent operating philosophy to shape leaders who create value wherever they go.
Most companies treat their operating model as a proprietary advantage to be protected. ITW does too—the 80/20 Front-to-Back Process is a trade secret. But the broader principles—Pareto-based prioritization, complexity reduction, customer-back innovation, decentralized accountability—are philosophies that any organization can adopt.
The question isn’t whether your company can afford to build this kind of operating culture. The question is whether you can afford not to.
Final Thoughts
Illinois Tool Works has been building products for over a century. But their most valuable output isn’t automotive components, food equipment, or welding systems. It’s the generation of operational leaders who carry the 80/20 operating philosophy into every business they touch.
The 10 alumni profiled here represent just the visible tip of a much larger iceberg. Thousands of former ITW leaders are operating in companies across every industry, applying the same principles of Pareto-based simplification, customer-back innovation, and decentralized accountability that made ITW one of America’s most consistently excellent manufacturers.
If you want to understand where the next wave of business transformation methodology is coming from, follow the ITW alumni network. They’re not waiting for the next management fad. They’ve been executing a proven operating philosophy for decades—and the results speak louder than any consulting pitch ever could.
