Every time a leader decides what work belongs together, where accountability sits, what gets centralized, which decisions are delegated, or how resources are allocated, they're making organization design choices. The org chart is simply the visible result.
That means organization design can't sit only with HR. It's one of the main ways leaders translate strategy into how the business actually operates.
Think of it like finance. Every leader needs financial literacy, finance professionals need deeper expertise, and some situations call for specialists. Organization design should work the same way.
Leaders need design literacy
Business leaders don't need to become expert organization designers. But they do need enough fluency to understand the system they're creating: structure, decision rights and accountability, governance, incentives, capabilities, and the interfaces between teams.
Without that literacy, leaders reach first for the most visible lever: structure. That's how organizations end up reorganizing without fixing the problem that caused the reorganization.
Consider a common pattern. A business unit restructures because decisions are taking too long, so it forms new teams and redraws reporting lines. Six months later, decisions are just as slow.
The same steering committee still approves everything. The boxes changed, but the decision rights didn't.
In practice, literacy shows up in the questions a leader asks before redrawing the boxes:
1. What problem am I actually trying to solve?
2. Is it really structural, or is it decision rights, incentives, governance, or how I'm leading?
3. What behavior needs to change, and what in the current design is reinforcing the behavior I have now?
Building this kind of literacy is why about 25% of our training programs now include business leaders, not just HR, and that share keeps growing.
HR needs deeper diagnostic capability
HR plays a different role. A strong HR partner helps leaders diagnose the organization as a system, rather than simply responding to requests for new boxes and reporting lines.
If a leader says, “My team isn’t collaborating,” the answer may not be a structural change. The issue could be conflicting accountabilities, unclear decision rights, competing incentives, or weak governance. Or it could be leaders reinforcing the wrong behaviors.
That's why good diagnosis has to look at behavior, not just design. Organizations don't operate according to their diagrams; they operate through the decisions and behaviors that happen every day. Two companies can have nearly identical structures and function very differently because leaders reward different things, escalate decisions differently, or reinforce different norms.
Structure, decision rights, governance, and incentives shape behavior. Leaders then reinforce those behaviors through what they pay attention to, tolerate, and reward. Good diagnosis looks at both the organizational system and the behavioral system.
HR's role isn't to take design away from the business. It's to help the business make better design choices.
Specialists for the most complex work
Some changes go beyond what leader literacy and HR capability can carry. Examples include restructuring across multiple business units, integrating an acquisition, or shifting the operating model of the whole enterprise.
These call for specialists with deeper methodology and the pattern recognition that comes from seeing many organizations through similar changes.
Where design capability belongs
The question is not whether organization design belongs to HR or the business.
It is whether the organization has enough design capability in the places where the decisions are being made.
