The X-Shaped Leader: Why the Next Era of Leadership Requires More Than Expertise

For decades, organizations prized specialists. Then came the idea of the T-shaped employee: deep expertise in one discipline, represented by the vertical line of the T, combined with enough breadth across other disciplines to collaborate effectively, represented by the horizontal line.

The emerging idea of the X-shaped employee, recently discussed by Shopify COO Jess Hertz, takes this further. An X-shaped person doesn't simply possess expertise and breadth. They can cross boundaries, connect disciplines, work effectively with other experts and contribute beyond the confines of their own role.

And I think this idea becomes even more important when we apply it to leadership.

Because the higher you move in an organization, the less your value comes from personally knowing the answer. Your value increasingly comes from your ability to connect what others know. Strategy with execution. Technology with people. Customer needs with organizational capability. Today's performance with tomorrow's possibilities.

And perhaps most importantly, people with one another.

That requires a very different kind of leadership.

Here are five questions to consider.

1. Do you still lead primarily through your own expertise?

Your expertise probably helped you get where you are. But eventually, the very thing that made you successful can become a constraint. X-shaped leaders know when to contribute their expertise and when to create the conditions for someone else's expertise to lead.

Ask yourself: When a difficult problem appears, is my instinct to provide the answer or to assemble the people capable of finding a better one?

2. Can you see beyond your function?

Transformation rarely respects an organizational chart. A technology decision becomes a workforce decision. A customer problem exposes an operating-model problem. A strategy decision creates capability implications three functions away. X-shaped leaders deliberately develop enough understanding across the enterprise to recognize these connections.

Ask yourself: How well do I understand the priorities, pressures and dependencies outside my own area of responsibility?

3. Are you a connector of people and ideas?

Some leaders accumulate knowledge. Others make knowledge move. They notice that one team has solved a problem another team is struggling with. They connect people who would not normally work together. They recognize patterns across seemingly unrelated issues. This is where the X becomes particularly powerful.

Ask yourself: Am I creating more connections across this organization, or inadvertently reinforcing the boundaries between us?

4. Do people become more capable around you?

This may be the most important question. Leadership is not simply about what you can accomplish. It is also about the capability that remains when you step away. An X-shaped leader doesn't need to be at the center of every decision. They strengthen judgment, relationships and ownership throughout the system so more people can act effectively without them.

Ask yourself: Does my leadership increase other people's ability to think and act, or increase their dependence on me?

5. Can you integrate competing perspectives without oversimplifying them?

Senior leadership increasingly happens in the tension between competing truths. Move faster and manage risk. Deliver this quarter and transform for the future. Use technology and protect the human experience. Create consistency and allow local adaptation. X-shaped leaders don't automatically choose one side. They become skilled at holding multiple perspectives long enough to discover what can be integrated.

Ask yourself: When faced with competing priorities, how quickly do I collapse the tension into an either/or answer?

And perhaps that is the bigger opportunity behind the X-shaped idea. The future doesn't necessarily belong to leaders who know the most. It belongs to leaders who can connect what the organization already knows, unlock what its people are capable of, and turn those connections into coordinated action.

That is a very different kind of expertise. It is the expertise of leadership itself.

Map Your X

Take 10 minutes this week and draw a large X on a piece of paper.

At each point, write:

Expertise: What do I know deeply enough to bring genuine value?

Breadth: Where do I understand enough of the wider business to see connections?

Connection: Which people, functions or ideas am I uniquely positioned to bring together?

Capability: How am I making other people better thinkers, decision-makers and leaders?

Then look at the center of your X and ask one final question:

Where am I still operating as the expert when the organization now needs me to operate as the connector?

Choose one meeting, decision or conversation this week and experiment with making that shift.
