I started as a corporate lawyer in Sydney and transitioned to working in large peacebuilding operations as part of the United Nations, and developing multi-million dollar budgets for donor funded projects. But when I launched my own firm, KSI, I found myself frustrated in conversations with my accountant about cash flow and margins.
That’s when I learned something important: expertise in your function doesn’t teach you to think like a CEO. Business acumen is a separate skill set. And without it, your expertise stays trapped inside your function.
What Business Acumen Actually Requires
Business acumen is the ability to understand how value flows through an organization—how money comes in, where it goes, how decisions in one area ripple across the whole system.
It’s not accounting. You don’t need to audit a balance sheet. But you need to understand how the business creates value, where it’s fragile, and how your decisions affect the equation.
I think of it as learning three languages. Most functional experts speak one fluently. CEOs speak all three. The transition from expert to business leader is about becoming multilingual.
The Three Languages
Language 1: Financial Literacy
This is the language of the P&L and balance sheet. Revenue, costs, profit, cash flow, return on investment.
Most functional experts avoid this. It feels mathematical and remote—disconnected from the work they care about.
The reframe: financial literacy isn’t about the numbers. It’s about what the numbers mean.
Revenue tells you what customers think your solution is worth. Cost structure tells you where your business is fragile. Profit margin tells you how much error you can absorb. Cash flow tells you whether you can pay people next month.
The strategic questions: Where does revenue originate? What’s the cost structure? What happens to profit if revenue grows 20%, does profit grow proportionally, or is the relationship non-linear? Could we survive a downturn?
Language 2: Systems Thinking
This is the language of interdependence—how the parts of the business connect and influence each other.
A functional expert asks: “How do I optimize my function?” A CEO asks: “If I do X in my area, what happens in someone else’s area?”
This is getting on the balcony. Stepping out of the day-to-day action to see the larger pattern. How does marketing’s lead generation connect to sales’ conversion rate? How does product’s development velocity affect customer success’s workload? Where does one function’s optimization damage another function’s performance?
The strategic questions: Who are our key stakeholders and what do they need? What happens if we push for lower costs—does it damage customer experience, increase churn, kill innovation? Where are the bottlenecks in how we operate?
Language 3: Strategic Positioning
This is the language of why your business exists and what makes it different.
Who are you serving? What problem do you solve? Why would customers choose you over alternatives? What’s your competitive advantage—and is it durable?
Most functional experts are executing strategy. CEOs are making strategy. The gap between the two is fluency in this third language.
The strategic questions: What’s our unique value? Where are we strong versus vulnerable? What trends will change our competitive position? Should we compete on cost, differentiation, or something else entirely?
The Transition: From Expert to Business Leader
You don’t ditch your expertise. You build on top of it.
When I moved from practitioner to leading organizations, I didn’t stop knowing conflict resolution. I started asking: How does conflict resolution fit into the business model? How does it change who we can serve? What’s the ROI? Does it differentiate us?
That’s the shift. Your expertise becomes a strategic asset instead of just a functional skill.
The learning strategy:
Start with Financial Literacy. Spend a quarter understanding your organization’s business model. Ask your CFO to walk you through the P&L—not a summary deck, the actual numbers. Understand what drives revenue and where costs concentrate.
Then build Systems Thinking. Map out the major functions and how they interact. Where do they work smoothly? Where does one function’s success create problems for another? Where are the hidden dependencies?
Finally, develop Strategic Positioning. Study your industry. Understand your competitors. Develop a point of view about where the business should go—not just within your function, but across the enterprise.
Why This Matters
Brilliant people plateau when they never learn to think beyond their specialty. They couldn’t translate expertise into business impact. They couldn’t make the case for investment in their work. They couldn’t contribute in a strategy meeting.
Business acumen isn’t about becoming less of an expert. It’s about becoming a strategic expert—someone whose deep knowledge is grounded in how it creates value for the whole organization.
That’s the difference between being essential in your function and being essential to the business.
