The Harvard Business School case likewise dates the transformation to April 2005, when Nayar became President, describing him as recognizing that HCL needed drastic change and then leading the first phase of the transformation.
The architecture that subsequently emerged was remarkably coherent:
1. Mirror Mirror — confront reality
Establish Point A honestly and create a compelling Point B.
2. Trust through Transparency — change information architecture
Open financial and organizational information much more widely.
3. Invert the Pyramid — change accountability architecture
Make enabling functions and management accountable to employees in the customer-facing “value zone.”
4. Recast the Office of the CEO — change power architecture
Move responsibility for transformation away from the CEO and toward employees themselves.
That is already a fairly sophisticated OD architecture, even if Nayar didn't necessarily sit down and call it an “OD model.”
And then came concrete mechanisms: employee service tickets for support functions, open 360-degree feedback, greater transparency, reverse accountability and distributed decision-making. Nayar himself publicly shared his 360 feedback; eventually thousands of managers participated in the process.
This changes how I would describe the role of OD
The traditional formulation might be:
CEO → Strategy
CHRO/OD → Organization & culture
Business → Execution
The cases we've been discussing suggest that major transformation often doesn't work so neatly.
Nayar was simultaneously making decisions about:
Strategy + structure + power + information + accountability + leadership + culture + customer value creation.
Those aren't separate interventions. They're an interconnected organizational system.
That's OD at enterprise scale.
The CEO therefore cannot sensibly outsource it to the OD department.
But neither should the CEO personally design every mechanism.
I'd frame the respective responsibilities this way:
| Transformation layer | Primary ownership |
|---|---|
| Why must we transform? | CEO + Board |
| What must become fundamentally different? | CEO + Executive Team |
| Business/strategic choices | CEO + Business leadership |
| Organization architecture | CEO + CHRO/OD + Executive Team |
| Operating model & decision rights | CEO + Business/Functional leaders |
| Leadership behaviours | CEO models; leadership system reinforces |
| Talent/reward/performance systems | CHRO + business |
| Intervention design/methodology | OD/HR + specialists |
| Implementation | Line organization |
| Institutionalization | Management system |
The crucial distinction is therefore:
CEO owns the organizational thesis; OD helps turn that thesis into organizational architecture.
That's different from saying “OD owns culture change.”
