"The best way to fail at inventing something is by making it somebody's part-time job."

Working Backwards, Colin Bryar and Bill Carr

The Strategic Paradox

“Culture eats strategy for breakfast” is a phrase so often repeated that it risks becoming cliché. But it’s true. And this is never more obvious than when companies try to pursue a new direction while anchored to the KPIs, habits, and incentives of their current operating model. What’s often missing from the conversation, however, is a deeper understanding of what drives culture.

Culture might eat strategy for breakfast, but KPIs drive culture.

Culture doesn’t just happen. KPIs drive culture. And when a new strategy is launched but measured by the same KPIs that sustain the existing business, it’s almost guaranteed to fail.

The KPI Prison

When a company decides to pursue a new market opportunity that's tangential to its core business, the natural inclination is to assign this initiative to an existing leader who has the experience, credibility, and a track record of execution. But this leader already has a full plate of responsibilities tied to KPIs that reflect the current business model.

These existing KPIs become a prison. When performance review time arrives, when quarterly earnings calls loom, when budget allocations are determined, the leader will inevitably prioritise the metrics they're evaluated on. The new initiative, no matter how strategically important, becomes the "extra credit" work that gets attention only after the core business demands are met.

This is where the concept of the Single Threaded Leader becomes essential.

The Single Threaded Solution

A single threaded leader is someone who is dedicated 100% to a single initiative. No distractions. No dual mandates. No divided focus.

This isn’t just about task allocation, it’s about organisational commitment. By creating a single threaded leader role, a company is signaling that the new strategy is not an experiment, side project, or hobby. It is a serious bet.

This leader has their own team, their own KPIs, their own resources. They are empowered to build from first principles without being hampered by the existing logic of the current business. In many cases, this means establishing an entirely new department, unit, or even legal entity.

The Amazon Example: Betting on Digital

Amazon's creation of its Digital Media division provides the perfect case study in single threaded leadership. In 2003, after Steve Jobs demonstrated iTunes for Windows and predicted that "CDs would go the way of other outdated music formats," Jeff Bezos faced a critical decision. Rather than launching an "all-hands-on-deck project to combat this competitive threat," Bezos made a counterintuitive choice: he appointed Steve Kessel as a single-threaded leader for Digital, reporting directly to him.

The organisational challenge was immediate and personal. As Bill Carr recalls in the book Working Backwards: "What I didn't get was why Steve and I had to change jobs and build up a whole new organisation. Why couldn't we manage digital media as part of what we were already doing?" The existing physical media business was thriving, generating substantial revenue and employing experienced teams with established supplier relationships.

But Bezos understood the KPI trap: "Jeff felt that if we tried to manage digital media as a part of the physical media business, it would never be a priority. The bigger business carried the company after all, and it would always get the most attention."

The challenge in a large organisation is that you want an experienced and highly capable person to lead the new initiative. But this is going to feel like a demotion. Amazon positions it differently: "At Amazon, it was not a demotion. It was a signal that we were thinking big and investing in digital for the long term."

The company measured leadership success not by current team size, but by future opportunity scale. As Bill Carr later reflected: "this sudden job change, the one I'd been so disappointed by, would prove to be not only the right thing for the company but also one of the best things to ever happen for my career."

The Four Zones Framework

To understand why single threaded leadership is so critical, it helps to view strategy through the lens of the Four Zones Framework (popularised by Geoffrey Moore):

  • Incubation Zone: Where new ideas are tested, explored, and validated.

  • Transformation Zone: Incubated ideas that show promise receive additional funding and support to validate the business idea.

  • Productivity Zone: Supports scaling and operational excellence of ideas that graduate from transformation

  • Performance Zone: The existing business that drives revenue and profit today.

Most companies are structured almost entirely around the Performance and Productivity zones. These zones dominate the budget, the headcount, and, critically, the KPI dashboard. The culture is hardwired to protect and optimise the existing business.

But incubation and transformation need special care.

They are fragile by design. They don’t scale linearly. They look inefficient. Their KPIs are lagging indicators, not leading ones. And they can be crushed, culturally and operationally, if forced to compete for attention with the current cash cows.

That’s why leaders in incubation and transformation efforts must be single threaded. If a leader is trying to both optimise the current business and nurture a new one, the core will win every time. Not because the leader lacks vision, but because the gravitational pull of existing KPIs is too strong.

Single Threaded Leaders as Culture Shapers

When you appoint a single threaded leader, you’re not just assigning ownership - you’re changing the rules of engagement.

  • You’re giving someone permission to say no to legacy processes.

  • You’re sending a cultural signal: this matters enough to stand alone.

  • You’re redefining success metrics in alignment with the new ambition.

In essence, you’re building a new culture around a new set of KPIs, separate from the existing business, and giving it time and space to grow.

Implementation Framework

The Amazon Digital Media case reveals three critical elements for successful single threaded leadership:

Organisational Separation: Bezos changed the reporting structure so that "Steve reported directly to Jeff, a clear sign that Digital was a high priority." This meant Steve "was not encumbered with the many responsibilities that went with managing any of Amazon's then-current businesses" and the rest of the business would not be required to spend any of their time on Digital.

Resource Independence: Amazon used "the two-pizza team structure, which allowed our Digital teams to not be dependent on or a distraction to the engineering and business teams running the retail and marketplace business." This eliminated the resource conflicts that doom many transformational initiatives.

Leadership Focus: Bezos himself "made an explicit choice that he would devote a significant portion of his time to working directly with Steve and the leaders in Digital." This top-level commitment was essential because "transformations are expensive, risky, and exhausting."

The result validated their approach: "If we had tried to figure out how to deliver digital media while also managing our online physical-media business, we could not have moved quickly enough. We would not have thought big enough about how to reinvent the customer experience as we did when we built our own e-reader device and service."

The Courage to Separate

The most challenging aspect of implementing single threaded leadership isn't operational, it's psychological. It requires executives to resist the comfortable illusion that new initiatives can succeed as "side projects" within existing structures. "Because transformations are expensive, risky, and exhausting, in most years the transformation zone is likely to be empty."

The companies that successfully navigate disruption are those willing to create parallel leadership structures, separate governance models, and distinct success metrics. They understand that "teams that are autonomous and led by a clear mandate are able to align themselves quickly towards their goal."

In an era where strategic agility determines survival, single threaded leadership isn't just a management technique - it's a competitive necessity. Amazon's Digital Media division eventually became one of the company's most valuable assets. The question isn't whether your next transformational initiative deserves dedicated leadership, but whether you can afford to let it fail as someone's part-time job.

As Amazon learned: "The customer experience would undoubtedly have been a subpar mishmash of the physical and digital business approaches. We had to start from scratch." Sometimes the courage to separate is the only path to transformation
