One of the most valuable aspects of earning the CDFO (Certificate in Design Firm Operations) is the way it connects leadership theory to practical application in the A/E industry. The CDFO isn’t just another credential — it’s a roadmap for understanding how operations, finance, people, and leadership all intersect to strengthen a firm.

John Maxwell’s 21 Irrefutable Laws of Leadership makes one thing crystal clear: leadership is influence, nothing more, nothing less. Titles, job descriptions, or authority might get short-term compliance, but they don’t inspire long-term loyalty or commitment. Authentic leadership happens when people choose to follow you — not because they must, but because they want to.

Influence Over Authority

Think about the best leader you’ve worked with. Chances are, it wasn’t their title that inspired you. Instead, it was their ability to connect, to communicate vision, and to make you feel part of something bigger than yourself. That’s the essence of influence.

By contrast, positional authority might secure short-term results, but it often creates dependency and fear. Influence builds trust, ownership, and momentum that outlasts a single project or even a leader’s presence.

What Does Influence as a Leadership Style Look Like?

When leaders adopt influence as their style, they move away from “command and control” and lean into inspiration and collaboration. Here are a few ways it shows up:

• Integrity and Character – People follow leaders they believe in.
• Relationships and Trust – Influence grows out of genuine connection, not transactions.
• Knowledge and Credibility – Expertise creates confidence in decision-making.
• Vision and Communication – A compelling “why” inspires others to commit.
• Consistency in Actions – Influence is earned every day, not in a single moment.

Real-World A/E Examples of Influence in Action

Influence isn’t reserved for the CEO or principal. It shows up across our firms in roles that, at first glance, might not look like “leadership” positions — but the impact is undeniable.

• The Controller Who Shapes Strategy
  Even without being in a line position, a Controller with deep financial expertise can influence executive leadership. By identifying trends such as increases in chargeability or a decline in project multipliers, the Controller provides insights that directly impact decisions on staffing, pricing, and project delivery. Their credibility makes them a trusted advisor, and their influence extends beyond the accounting department to the entire firm’s bottom line.
• The Operations Professional Who Understands Contracts
  An operations person who knows the ins and outs of contract language may not sign agreements, but their guidance helps project managers avoid pitfalls. By highlighting scope risks, billing terms, or liability concerns, they influence project setup and execution, saving the firm from costly missteps and strengthening client relationships.
• The PMA Who Masters Scheduling
  A Project Management Assistant (PMA) who truly understands scheduling can anticipate resource conflicts before they become roadblocks. By providing clear, data-driven recommendations, they influence how project managers allocate people, prioritize tasks, and meet deadlines. Their influence ensures smoother delivery and greater client satisfaction — all without holding the official title of “project manager.”

These examples show that leadership through influence is alive across every discipline of an A/E firm. Expertise, credibility, and a willingness to share knowledge give professionals the ability to shape outcomes and elevate the entire organization.

Influence Creates Multipliers

The real power of influence is its ripple effect. A leader who models integrity, shares knowledge, and invests in people creates followers who in turn become leaders themselves. Influence multiplies through culture — shaping the way people treat each other, solve problems, and pursue goals long after the leader steps aside.

Practicing Influence Every Day

Leaders don’t wake up one morning suddenly influential. It’s a daily choice, built over time. Some practical steps:

• Listen more than you talk. Influence starts with understanding.
• Give credit generously. Recognition builds trust and loyalty.
• Mentor and empower. Help others succeed, and your influence grows naturally.
• Stay consistent. People respect what they can predict and rely on.

Final Thought

Influence isn’t just one aspect of leadership — it’s the essence of leadership. Authority may move people’s hands, but influence moves their hearts. And when hearts are engaged, results follow.

Leadership isn’t about the position you hold; it’s about the difference you make. Influence isn’t a tool in the leader’s toolkit — it is the toolkit.
