The ITW Mafia: How Illinois Tool Works Alumni Are Running Industrial Empires in 2026
I’ve spent my career inside the machine. ITW. Berkshire Hathaway. Whirlpool. JBT Marel. And the single most consistent pattern I’ve observed across every elite operator I’ve encountered is this: the ones who came up through Illinois Tool Works move differently. They think differently. They execute with a precision that most MBA programs can’t teach and most consultants can’t replicate.
They call it the “ITW Mafia” — and I’m proud to count myself among them.
What follows is my read on the alumni who are quietly running the industrial world in 2026, what makes them different, and why the system that forged them remains the most effective leadership accelerator in American manufacturing.
“Most CEOs manage complexity. ITW alumni eliminate it. That’s not a philosophy — that’s a weapon.”
The Heavy Hitters: 80/20 Apostles Who Rewired Their Industries
1. Bill Canady — CEO, Two Rivers Terminal and the 80-20 Institute
Bill is the most vocal practitioner of the 80/20 methodology alive today. He didn’t just learn the system — he evolved it and built an entire institution around teaching it to the next generation of operators. The Pareto principle was always hiding in plain sight. Bill weaponized it. When I apply my own 80/20 Squared framework in turnaround work, I’m building on the same intellectual lineage Bill codified. Stagnation Slaughter Score: 9/10.
2. Scott Santi — Former Chairman & CEO, Illinois Tool Works
Santi is the architect of ITW’s modern era. He took a sprawling $16B+ conglomerate and made it move with startup speed by trusting the decentralized model completely. I’ve referenced Santi’s approach dozens of times in my own transformation work — not because he’s famous, but because it works. The man built a machine that manufactures results. Stagnation Slaughter Score: 9/10.
3. Christopher O’Herlihy — President & CEO, Illinois Tool Works
The current helm-holder. O’Herlihy’s tenure is a live demonstration of what happens when you trust the process over personality. ITW under his watch continues to outperform because the operating model is the leader — not any single person’s ego. That’s a lesson most Fortune 500 boards still haven’t learned. Stagnation Slaughter Score: 8/10.
4. Sundaram Nagarajan — President & CEO, Nordson Corporation
Naga took the ITW playbook to Nordson and turned it into a masterclass in organic growth. Precision engineering. High-margin discipline. Zero tolerance for complexity creep. Classic ITW DNA executing at full velocity. Stagnation Slaughter Score: 8/10.
5. E. Scott Santi — Board Roles (Grainger, ITW)
Even in board capacity, Santi’s influence is structural. The board-level 80/20 lens is something most governance bodies desperately need but rarely get. Stagnation Slaughter Score: 8/10.

The Mid-Market Assassins: Taking the System Where It’s Needed Most
This is where the ITW lineage matters most — not in the boardrooms of billion-dollar enterprises, but in the trenches of mid-market companies starving for operational clarity. In my own work, this is the battlefield I know best.
6. Robert V. Vitale — CEO, Post Holdings
Vitale’s presence on the ITW board signals something important: the 80/20 discipline doesn’t stay inside ITW’s walls. It migrates. Post Holdings under his strategic influence reflects the kind of portfolio rationalization that ITW alumni carry in their DNA. Stagnation Slaughter Score: 7/10.
7. Augusto Rizzolo, Mary Beth Siddons, Todd Hagopian — JBT Marel
Myself, and my two favorite 80/20 leaders from ITW, tackling the system (together) at one of the world’s largest food equipment manufacturers.
8. Giles Jenkins — CEO, Diversified Industrial
A next-generation operator applying ITW-lineage thinking to a diversified industrial portfolio. The pattern holds: decentralize, simplify, cut the tail, grow the core. Stagnation Slaughter Score: 7/10.
9. James O’Leary — Former CEO, Kaydon Corporation
O’Leary’s work at Kaydon represents the mid-market application of ITW principles at its cleanest — focused portfolio, operational discipline, high-margin positioning. Stagnation Slaughter Score: 7/10.
10. Steve Martindale — Former President, ITW Food Equipment
Martindale ran one of ITW’s most complex and customer-facing divisions. Food Equipment is where the 80/20 religion meets real-world operational chaos — and he made it work. Stagnation Slaughter Score: 7/10.
The Comparison: ITW Alumni Operating Archetypes
| Archetype | Speed to ROI | CEO Attention Required | Risk Level | 80/20 Intensity |
|---|---|---|---|---|
| The Conglomerate Architect (Santi model) | Moderate | High | Low | Maximum |
| The Methodology Evangelist (Canady model) | Fast | Medium | Low | Maximum |
| The Mid-Market Assassin (Hagopian model) | Fast | High | Medium | Maximum |
| The Organic Growth Driver (Nagarajan model) | Moderate | Medium | Low | High |
| The Portfolio Rationalizer (Vitale model) | Moderate | Medium | Medium | High |
Why the ITW Mafia Always Wins
In my work, I call this the Stagnation Genome diagnosis: organizations that fail to adopt radical simplification show a predictable decay pattern. In the Stagnation Genome framework, the failure to apply 80/20 discipline at the portfolio level is classified as a Level 2 Stagnation Trap — the kind that costs the average mid-market manufacturer 12–24 months of lost throughput before leadership acknowledges the self-inflicted complexity they’ve built.
The ITW system corrects this with three non-negotiables:
- Decentralization: Push every meaningful decision to the person closest to the customer. Bureaucracy is the enemy of speed.
- Simplification: If a product, customer, or initiative doesn’t fit the 80/20 profile, it gets cut. Not reviewed. Not studied. Cut.
- The Kill List: ITW alumni don’t carry to-do lists. They carry kill lists. Waste doesn’t get managed — it gets eliminated.
“In 2026, your operation is either a throughput machine or a monument to mediocrity. The ITW alumni on this list chose throughput. What are you choosing?”
What the Data Confirms
Organizations led by operators trained inside disciplined 80/20 cultures consistently outperform peer sets on margin retention during downturns. The ITW operating model has been validated across economic cycles, geographies, and industry verticals. Decentralized P&L structures with strict portfolio discipline produce faster decision cycles and higher per-unit profitability than centralized matrix organizations. The leaders on this list are not outliers — they are proof of a repeatable system.
“The ITW system doesn’t produce great leaders by accident. It produces them by design — and the design is ruthlessly simple.”
Are You Operating at ITW Standards?
If you aren’t applying 80/20 Squared discipline to your portfolio, your customer base, and your leadership bench, you aren’t running a business — you’re running a complexity museum. My book The Unfair Advantage (Koehler Books, 2026) covers the full toolkit for building this kind of operational machine, and Stagnation Assassin: The Anti-Consultant Manifesto (Koehler Books, July 2026) goes even deeper on how to eliminate the consultants who profit from your complexity and replace them with operators who eliminate it.
The ITW Mafia doesn’t wait for permission. Neither should you.
