There was an old saying in Sales: The moment you win a new customer is the moment you start losing that customer.

The job of the account team was simple, deliver great products and services, deepen trust, and retain the relationship for 5–10 years… at least until your champion got promoted.

That world is gone.

In today’s volatile business environment, turnover is constant. Restructuring. Layoffs. M&A. PE ownership. “Strategic realignment.”

In many industries, 70–90% of your direct customer contacts may change within 2–3 years.

As part of a Commercial Leadership program I’m building for a pharmaceutical client, a sales manager told me:

“You spend years building trust, winning the business, growing the account. Then one day, you find out your customer was escorted out of the building. And now every competitor is flooding the zone, discounting, and trying to reset the narrative with their ‘latest and greatest’ product.”

That’s not bad luck. That’s the new normal.

So the question isn’t if your direct customer will leave.

The question is:

Are you proactively preparing for it?

Here are five ways to do exactly that.

Some of my best blogs come directly from interviews with subject-matter experts while we are designing business acumen simulations.

Recently, I interviewed a senior line manager at a high-tech company. He shared a story that was equally hilarious and horrifying.

They were launching a major AI-enabled services initiative to support their core hardware platform. Big opportunity. Big revenue potential. Big margin expansion if executed well.

The marketing team was already a little chaotic. Eight people. Project managers. Event planners. Administrators. Everyone busy. No one is quite sure who owned what.

And then…

Corporate procurement stepped in.

“We were told we had to route every vendor, every venue contract, every service agreement through corporate procurement,” he said. “It turned managed chaos into mismanaged chaos.”

Procurement didn’t understand the product. They didn’t understand the launch strategy. They didn’t understand the revenue objectives. They didn’t understand the margin profile of the new services.

But they absolutely understood how to slow things down.

The tipping point?

Today’s blog takes me back to one of my favorite sources of insight: real executives wrestling with very real leadership dilemmas, the kind that eventually become powerful leadership simulations.

This person was crushing his numbers. He was innovative, decisive, and charismatic.

He forged loyal followership. He moved fast. He broke things. He got results.

He was, in the executive’s words, a “bull in a China shop who went to President’s Club every year for great performance.”

And here was the problem:

“In every role he’s had, he’s essentially planned for and executed a coup. But he never sees himself as leading the coup. He always feels like he’s just adjacent to it. Like the organization is dysfunctional and he’s simply stepping in to fix it.”

That phrase stuck with me.

Coup-adjacent leadership.

Not openly rebellious. Not formally insubordinate. But constantly destabilizing the system in the name of results.

The executive’s question to me was simple and profound:

“How do we develop leaders who can recognize this pattern, and neutralize it, without killing innovation?”

That’s a serious leadership challenge.

Here are five lessons in business acumen and leadership created from understanding the dynamics of the “coup-adjacent” environment.

Picture a world without the internet. And no voicemail. And no email.

Business hours were 8:30 a.m. to 5:30 p.m., excluding the commute, which could easily stretch to an hour each way, and everyone was expected to be in the office five days a week.

Companies functioned through receptionists who took messages on pink message slips. If you were in sales or on the road, you called in a few times a day to retrieve them. Gentlemen wore suits and ties. Women wore professional attire. That was the norm.

This was the late 1980s into the early 1990s.

Then, around 1992, Dockers launched a campaign encouraging professionals to dress “down” on Fridays. Levi Strauss & Co. followed by mailing a brochure titled A Guide to Casual Businesswear to 25,000 HR managers across corporate America.

And the debate was on. Some leaders argued it was unprofessional and would start a slippery slope. Others believed it would create a more relaxed, collegial workplace.

At the time, it felt like a big cultural moment. But here’s the thing:

It was never really about the pants.

Wow, the responses from my earlier blog on the demise of the Bahama Breeze restaurant chain have been really interesting. I didn’t realize people liked it so much, and I am very happy to receive all the positive feedback about the business acumen learning lessons. For full transparency, I wrote a much longer version of the first blog, and, as I often do when that happens, I created a “white paper” that we hand out as additional readings and follow-ups for Advantexe’s Business Acumen training sessions. As it would have made the blog too long, I archived some of the writing for another day, but since there has been such positive buzz, I am thrilled to share a “part two” and continue the dialogue with more business acumen lessons from the demise of Bahama Breeze.

Burger Chef (1960s Failure) vs Bahama Breeze (2026 Failure)

The failure of the Burger Chef chain is another fascinating iconic example that provides deep insights into strategy, finance, and business acumen. If you have never heard of Burger Chef, here is a quick background: Burger Chef was once one of the fastest-growing and most innovative fast-food restaurant chains in the United States. Founded in 1954 and expanding rapidly through the 1960s and early 1970s, Burger Chef peaked at more than 1,000 locations nationwide. At its height, it was a serious competitor to McDonald’s and Burger King and was widely seen as a legitimate long-term player in the emerging fast-food industry.

What made Burger Chef successful early on was its willingness to innovate. It introduced flame-broiled burgers, offered menu customization through its “Build Your Own Burger” concept years before customization became standard, and experimented with family-friendly dining features that differentiated it from its peers. The company was eventually acquired by General Foods, which provided capital, scale, and corporate backing. However, as competitors improved speed, consistency, and unit economics, Burger Chef struggled to keep pace. By the early 1980s, the brand had lost momentum; locations were converted or closed, and Burger Chef quietly disappeared, leaving a powerful lesson in how even early category leaders can fade when differentiation erodes, and reinvention comes too late.

There’s an interesting cultural footnote to the Burger Chef story that reinforces this lesson. In the TV show, Mad Men, Don Draper famously pitches the Burger Chef account by reframing the brand not as fast food, but as a symbol of family, connection, and togetherness in a rapidly changing America. It’s widely regarded as one of the most emotionally powerful pitches in the series, and a reminder that Burger Chef once had real cultural relevance and a compelling brand story. Yet even the most brilliant positioning and storytelling couldn’t ultimately overcome eroding unit economics, rising competition, and a failure to adapt the operating model. Marketing can buy time. It can’t fix fundamentals.
