Back in 1982, two McKinsey consultants named Tom Peters and Robert Waterman Jr. did something that changed the corporate world forever. They wrote a book. It wasn't just any book, though. In Search of Excellence became a cultural phenomenon, selling millions of copies and turning the authors into the first real "business gurus." Honestly, before this, management books were mostly dry academic texts that put people to sleep.
Peters and Waterman changed the vibe.
They looked at 43 of the most successful American companies at the time—heavy hitters like IBM, 3M, and Disney—to figure out what made them tick. What they found wasn't a complex mathematical formula or a secret tax loophole. It was mostly about people. It was about being "human-centric" in a world that was becoming increasingly obsessed with cold, hard data.
The Eight Principles That Defined an Era
The core of the book is built around eight traits that these "excellent" companies shared.
First, they had a bias for action. Basically, they didn't sit around in meetings for six months debating a single decision. They tried things. If it failed, they fixed it. If it worked, they ran with it. This "do it, fix it, try it" mentality is something we take for granted today in the world of tech startups and "lean" methodologies, but in the early 80s? It was revolutionary.
They also believed in staying close to the customer. This sounds like a no-brainer now, but you'd be surprised how many CEOs back then never actually talked to the people buying their products.
One of the most famous takeaways from the book is Management by Wandering Around (MBWA). Think about Hewlett-Packard. The idea was that managers shouldn't just sit in corner offices looking at spreadsheets. They should literally wander around the office or the factory floor, chatting with employees, asking what’s going wrong, and seeing the work firsthand. It’s about being present. It’s about empathy.

Other principles included:
- Autonomy and entrepreneurship (letting employees take risks).
- Productivity through people (treating workers like partners, not just cogs).
- Hands-on, value-driven leadership.
- "Stick to the knitting"—don't start buying companies in industries you don't understand.
- Simple form, lean staff.
- Simultaneous loose-tight properties (strict on values, flexible on how the work gets done).
The Big Elephant in the Room: The "Failure" of the Excellent
If you talk to business school professors today, some of them might scoff at the book. Why? Because a lot of those "excellent" companies didn't stay excellent.
Just two years after the book was published, Business Week ran a famous cover story titled "Oops!" pointing out that several of the companies Peters and Waterman praised—like Atari, NCR, and Wang Labs—were suddenly struggling. Some eventually went bankrupt. Others just became mediocre.
Does that mean the book was a lie?
Not really.
Success is never a permanent state. Markets change. Technology shifts. The "excellence" Peters and Waterman described was a snapshot in time. They caught these companies at their peak, doing things right. The fact that IBM eventually struggled with the rise of the PC or that Sears failed to adapt to the internet doesn't invalidate the value of having a bias for action or treating your employees well. It just proves that you can't stop innovating once you reach the top.

How In Search of Excellence Predicted the Modern Workplace
Look at Google or Netflix today.
They don't use the exact terminology from 1982, but their culture is basically In Search of Excellence on steroids. When Netflix says they want "Context, Not Control," that is a direct descendant of the "loose-tight properties" principle. When Amazon obsesses over customer feedback, they are "staying close to the customer."
The book's real legacy isn't the list of companies. It’s the shift in mindset.
Before this book, management was seen as a science—something you could solve with a calculator. Peters and Waterman argued that management is actually an art. It’s about storytelling, culture, and shared values. They moved the focus from the "hard" S's of the McKinsey 7-S framework (Strategy, Structure, Systems) to the "soft" S's (Style, Staff, Skills, and Shared Values).
It turns out the "soft" stuff is actually the hard stuff.
Actionable Lessons for the Modern Leader
You don't need to be the CEO of a Fortune 500 company to use these ideas. Whether you're running a small team or a solo freelance business, the fundamentals of excellence still apply.

Stop over-analyzing and start doing.
If you have an idea, find the smallest possible way to test it today. Don't write a 20-page business plan. Just launch a "pilot" and see what happens. The "bias for action" is the ultimate cure for procrastination and corporate gridlock.
Kill the bureaucracy.
If your team spends more time reporting on work than actually doing work, you have a problem. "Simple form, lean staff" means keeping the hierarchy as flat as possible. Every layer of management you add is another layer of noise between the leadership and the customer.
Define your non-negotiables.
This is the "tight" part of "loose-tight." What are the three values your business will never compromise on? Once those are set, give your people (or yourself) the "loose" freedom to achieve results in whatever way works best.
Listen to the frontline.
If you're a manager, get out of your inbox. Go talk to the person who handles customer complaints. Talk to the person on the assembly line. They know what's broken way before the data shows up on your dashboard.
Excellence isn't a destination you reach and then retire. It’s a way of behaving every single day. The companies in the book may have faltered, but the human principles of leadership they highlighted are timeless. You won't find excellence in a spreadsheet; you'll find it in how you treat your people and how fast you can turn a good idea into a reality.
Summary Checklist for Excellence
- Prioritize Action: Move faster than you think you should.
- Obsess Over Customers: Don't guess what they want; ask them.
- Empower Individuals: Give people the autonomy to be "intrapreneurs."
- Simplify Everything: If a process is complex, it's probably broken.
- Focus on Values: Lead with "why" before you get to the "how."
