The hardest leadership problems rarely belong to one team. A customer problem may involve sales, product, technology and customer success. A transformation programme may require finance, operations, HR and IT to move together. A strategic decision may look simple from one function’s perspective and create consequences for another.
Yet organisations are still often designed around functions, reporting lines and individual objectives. This creates a leadership challenge. The people you need to influence may not report to you. Their priorities may be different. Their measures of success may be different. And they may have no reason to treat your priorities as more important than their own. At that point, leadership cannot rely on authority. It has to create alignment.

How Do Leaders Influence Peers?
Influencing a direct report and influencing a peer are fundamentally different. A manager has formal authority. They can set expectations, allocate work and hold someone accountable. A peer relationship does not offer the same leverage. The other leader has their own responsibilities, pressures and priorities. That means influence begins with understanding rather than instruction.
Before asking another function to support an initiative, a leader needs to understand what matters to that function. What are they accountable for? What pressures are they managing? What risks do they see? What would supporting your priority make harder for them? This changes the conversation from “I need your team to do this” to “How can we solve this problem in a way that works for both of us?”
The second question creates space for collaboration and recognises a reality of senior leadership. Influence is not just about getting people to do what you want. It is about creating enough shared understanding that employees can commit to a solution together.
Why Do Functions Become Territorial?
Functional boundaries exist for good reasons. They create expertise, accountability and focus. The problem begins when functional accountability becomes functional protection. Sales may optimize for revenue and finance may focus on cost and risk. Operations may prioritise efficiency and technology may prioritise stability and security. HR may focus on organisational capability and employee experience.
Each perspective can be valid. But when every function optimises only for its own objectives, the organisation can become less effective as a whole. Territorial behaviour is often not about difficult personalities. It can be created by the system itself. Different targets, incentives, information flows and decision rights can encourage leaders to protect their own territory. That is why collaboration cannot be fixed by telling people to collaborate more. The organisation also needs to make shared ownership possible.
What Does Shared Ownership Look Like?
Shared ownership begins when leaders stop asking, “Whose problem is this?” Instead, they ask, “What outcome are we jointly responsible for?” That distinction matters. Imagine a customer experience problem that moves between sales, implementation and customer success. Each function may complete its own part of the process correctly while the customer still experiences a fragmented journey.
Every team can say, “We did our job.” The organisation still has a problem.
Shared ownership moves attention from individual tasks to the outcome that connects them. This needs shared measures, joint decision-making, cross-functional working groups or simply a clearer understanding of where one team’s work affects another. The specific mechanism will vary, but the principle remains the same: people collaborate more effectively when they can see what they are collectively accountable for.
What Happens When Priorities Conflict?
Cross-functional leadership becomes most visible when priorities collide. Every organisation has competing demands. One team wants speed. Another wants risk controls. One wants flexibility. Another wants consistency. One wants to invest now but another wants to protect the current budget. There may not be a solution that gives everyone exactly what they want.
The leadership task is therefore not to eliminate conflict. It is to make the conflict productive. That means bringing the competing priorities into the open. What are we optimising for? What trade-off are we making? Which risk are we willing to accept? What happens if we delay? Who is affected by the decision? What does the wider organisation need from us?
These questions create a more mature conversation than debating whose priority should win. Strong cross-functional leaders do not pretend that trade-offs do not exist. They help people make those trade-offs consciously.
How Can Leaders Build Collaboration Without Formal Authority?
Influence without authority depends heavily on credibility. People are more likely to collaborate with leaders who understand the wider business, keep commitments, share information and acknowledge the constraints of others. But credibility alone is not enough. Leaders also need to create clarity around the shared problem. A useful starting point is to establish four things:
- The shared outcome: What are we trying to achieve together?
- The interdependencies: Where does one team’s success depend on another?
- The trade-offs: What competing priorities or constraints do we need to acknowledge?
- The ownership: Who needs to decide, contribute, support or be consulted?
This makes collaboration more concrete. It also reduces one of the biggest sources of cross-functional frustration: assuming that everyone has the same understanding of the problem. They usually do not.
Collaboration Requires Better Conversations
Many cross-functional problems are ultimately conversation problems. Teams have different interpretations of the situation. Leaders make assumptions about each other’s motives. Concerns remain unspoken until they become resistance. Meetings become updates rather than places where decisions are made. Leaders can change this by becoming more intentional about the conversations they create.
Instead of asking only, “Do you agree?” ask: “What are we missing?”
Instead of asking, “Why can’t your team support this?” ask: “What would make this difficult for your team?”
Instead of saying, “This is our priority,”ask: “How does this priority interact with yours?”
These questions do not remove disagreement. They make disagreement easier to work with. And that is essential because collaboration does not mean everyone agrees. It means people can disagree while remaining committed to the larger outcome.

The Role of Leadership in Matrix Organisations
Matrix structures make these challenges even more visible. A project leader may depend on people who report to different functional heads. A transformation leader may need decisions from several executives. A programme manager may have responsibility for an outcome without direct control over the resources required to deliver it.
In these environments, leadership becomes less about command and more about orchestration. The leader has to connect people, clarify dependencies, surface conflicts and maintain momentum without assuming that authority will solve the problem. This requires a different kind of confidence.
You need to be able to influence without controlling, challenge without creating defensiveness and hold people accountable without pretending that you have authority you do not actually possess.
What Senior Leaders Can Practise
For leaders working across boundaries, three habits can make a big difference.
Start with the enterprise outcome. Before defending your function’s priorities, understand what the organisation needs as a whole.
Make dependencies visible. Identify where your team’s success depends on another team’s decisions, resources or behaviour.
Have a difficult conversation early. Cross-functional friction rarely improves when left unspoken. Surface conflicting priorities before they become personal or political.
These are not soft skills in the narrow sense. They are leadership capabilities required to operate in complex organisations.

Coaching for Leadership Across Boundaries
Cross-functional leadership can be particularly valuable territory for coaching because the challenge is often less about knowing what to do and more about understanding how you show up when you cannot control the outcome.
A leader may believe they are being clear when others experience them as demanding. They may believe they are protecting their team’s interests when peers experience it as territorial behaviour. They avoid challenging a powerful stakeholder as they assume the conversation will create conflict. Coaching creates space to see these patterns.
It can help leaders understand their own reactions, prepare for difficult conversations, test alternative approaches and become more deliberate about the influence they want to create. The deeper question is not simply, “How do I get people to cooperate?” It is “What kind of leader do I need to be when cooperation cannot be commanded?”

Leadership Begins Where Authority Ends
As organisations become more interconnected, leadership happens between teams rather than within them. The problems that matter often cross functional boundaries. The solutions need people with different expertise, incentives and perspectives to work together. No single leader can control all of the resources or decisions involved.
That makes alignment a leadership responsibility. The strongest cross-functional leaders do not try to eliminate organisational boundaries. They learn to work across them. They create shared understanding, make trade-offs visible, build trust and connect people around outcomes larger than any one function. Because leadership is increasingly about creating alignment where authority ends.
