When we talk about influence at work, most people picture the org chart. Seniority. Job titles. The ability to approve or block decisions. But reducing organisational influence to hierarchy alone is one of the most common mistakes a professional can make.
In reality, effective managers draw on three distinct sources of influence: role, expertise, and relationships. Understanding all three, and knowing when to lean on each, is what separates managers whose teams go through the motions versus those who have top performing teams.
Role Influence: Necessary, But Overrated
Role influence is what your job title gives you. It’s the authority to set direction, make decisions, manage people. It’s real, and it matters. But it’s far more limited than most new managers expect.
The core problem with role influence is that it usually produces compliance but not commitment. When people act because they have to, you often get the minimum. When they act because they feel motivated to, you get discretionary effort, the kind that drives top tier performance.
Research backs this up. Studies on self-determination theory consistently show that autonomy and intrinsic motivation are far stronger predictors of performance and wellbeing than external authority. Telling people what to do works in the short term; it erodes motivation over the long term.
Role influence is also a finite resource. You only have as much as the organisation grants you, and overusing it depletes it fast. The managers who deploy role power most effectively tend to use it sparingly, reserving it for moments that genuinely require it, which means it lands with weight when they do.
Short story: Use role influence as a last resort, not a first instinct.
Expertise Influence: The Underestimated Credibility Engine
Expertise power is the influence that comes from being genuinely knowledgeable about a domain, a system, a market, or a process. It’s the reason people seek out certain colleagues before making decisions, and why some voices carry more weight in a room regardless of their title.
For managers, expertise power often gets overlooked because management is supposed to be about people, not technical depth. But this is a false trade-off. Managers who maintain credible expertise, whether in their field, their industry, or even in the craft of management itself earn a different kind of respect from their teams. It signals that their judgement is grounded, not just positional.
Expertise power is also uniquely portable. Unlike role influence, it travels with you across organisations and roles. It compounds over time. And it’s one of the few sources of influence available to those without formal authority, which makes it especially valuable in matrixed or cross-functional environments where you’re regularly working with people who don’t report to you.
Short story: Keep investing in your knowledge. Credibility built on expertise opens doors that titles alone cannot.
Relationship Influence: The Multiplier Most Managers Underinvest In
Relationship influence is the ability to get things done through the trust, goodwill, and mutual understanding you’ve built with the people around you. It’s why some managers seem to cut through organisational friction effortlessly, approvals come faster, cross-team collaboration is smoother, and difficult conversations land better.
Pause here for a moment to think about the people in your organisation who lean heavily on relationships to get things done.
The research here is robust. Google’s Project Aristotle found that psychological safety, which lives or dies based on relational considerations, was the single strongest predictor of team performance. Studies on social capital in organisations consistently show that well-connected individuals are more effective, more influential, and more resilient to organisational change.
And yet, relationship-building is often the first thing that gets dropped when calendars fill up. It feels less urgent than the next deliverable. It’s harder to measure. However, the managers who treat relationships as infrastructure and not a nice-to-have consistently seem to outperform those who don’t.
Practically, this means they…
Host 1:1s that avoid status updates and instead make space to understand what motivates people, what’s frustrating them, and what they need to do their best work.
Have regular contact with peers and stakeholders outside their team (not transactionally, but genuinely). Understanding their priorities makes collaboration far easier when it matters.
Are willing to ask for help, not just offer it. Vulnerability builds trust faster than competence alone.
Short story: Relationships are the connective tissue of effective organizations. Failing to build them is a huge strategic mistake.
Balancing All Three: A Simple Audit
A useful starting point in getting ‘the mix’ right is an honest self-audit…
Role influence: Am I relying on authority to get things done more than I should? Do I have the credibility to use it judiciously when I need to?
Expertise influence: Is my knowledge current and credible? Do people seek out my perspective, or do I need to rebuild that reputation?
Relationship influence: Do I have genuine, trust-based relationships with the people I depend on most, including laterally and upwards, not just with my direct reports?
Most managers will find one area that’s stronger than the others, and at least one that’s been quietly neglected. That gap is usually where your next level of effectiveness lies.
Organisational power isn’t something to be suspicious of. It’s simply the capacity to get things done in large systems. The managers who understand that power is multidimensional, and who invest deliberately in all three sources, are the ones who build teams that thrive, projects that succeed, and careers that compound.
The org chart gives you a start. Expertise gives you credibility. Relationships give you reach. Used well, together, they give you everything you need to lead.
