Building an AI Center of Excellence: Structure, Roles & Best Practices
Learn how to build an AI Center of Excellence that drives enterprise AI success. Comprehensive guide covering organisational models, governance frameworks, and scaling strategies.
As organisations move from AI experiments to enterprise-wide deployment, a critical question emerges: how do we scale AI capabilities systematically? Random projects, siloed teams, and inconsistent approaches lead to duplicated effort, missed opportunities, and failure to capture AI's full potential. The answer for many organisations is an AI Center of Excellence (CoE).
This guide provides a comprehensive framework for building an AI CoE that drives real business impact. You'll learn the different organisational models, essential roles and responsibilities, governance structures, and strategies for scaling AI across the enterprise—drawing on lessons from organisations that have successfully built these capabilities.
Key Takeaways
- AI CoEs provide centralised leadership, expertise, and governance for enterprise AI success
- Choose your organisational model (centralised, federated, decentralised) based on size, maturity, and culture
- Essential roles include leadership (CoE Lead, Program Manager), technical (engineers, architects), and enabling (business partners, ethics)
- Governance covers strategy, ethics, development standards, risk management, and data governance
- A best practices library captures learnings and accelerates delivery across projects
- Scale through productising solutions, building platforms, embedding skills, and industrialising delivery
- Measure effectiveness across business impact, delivery, capability building, and quality dimensions
- Evolve your CoE as AI maturity grows—successful CoEs eventually distribute capabilities throughout the organisation

When Is an AI CoE Right for Your Organisation?
Signs You're Ready for an AI CoE
- ✓ Multiple AI projects underway or planned across different business units
- ✓ Duplicated effort and inconsistent approaches between teams
- ✓ Difficulty scaling successful pilots to enterprise deployment
- ✓ Scarce AI talent being pulled in too many directions
- ✓ Need for consistent governance and risk management
- ✓ Executive commitment to AI as a strategic priority
- ✓ Budget to invest in centralised AI capabilities
When a Formal CoE May Be Premature
- • Only one or two AI projects in early stages
- • No clear AI strategy or executive sponsorship
- • Limited budget for dedicated AI resources
- • Organisation not yet convinced of AI value
In these cases, start with informal AI leadership and build toward a CoE as AI activity increases.
AI CoE Organisational Models
There's no one-size-fits-all structure for an AI CoE. The right model depends on your organisation's size, culture, AI maturity, and strategic objectives.
Model 1: Centralised CoE
All AI resources, projects, and governance in a single central team that serves the entire organisation.
Advantages:
- • Consistent standards and quality
- • Efficient resource utilisation
- • Clear accountability
- • Strong knowledge sharing
- • Easier talent development
Challenges:
- • Can become bottleneck
- • Distance from business context
- • May feel bureaucratic
- • Business units lack ownership
Best for: Smaller organisations, early AI maturity, regulated industries needing tight control
Model 2: Federated (Hub and Spoke)
Central CoE provides strategy, standards, and shared services, while embedded AI resources in business units handle execution.
Advantages:
- • Balances consistency with agility
- • Close to business problems
- • Scales across large organisation
- • Business unit ownership
Challenges:
- • Coordination complexity
- • Potential for standards drift
- • Requires strong governance
- • More expensive (distributed resources)
Best for: Large organisations, diverse business units, moderate-to-high AI maturity
Model 3: Decentralised with Coordination
AI teams operate independently in business units with light-touch coordination through a virtual AI community or leadership council.
Advantages:
- • Maximum business alignment
- • Fast, autonomous decision-making
- • Lower coordination overhead
- • Business units fully own AI
Challenges:
- • Duplication of effort
- • Inconsistent practices
- • Difficult knowledge sharing
- • Governance gaps
Best for: Highly autonomous business units, very high AI maturity, tech-native organisations
Choosing Your Model
| Factor | Centralised | Federated | Decentralised |
|---|---|---|---|
| Organisation size | Small-Medium | Large | Any |
| AI maturity | Low-Medium | Medium-High | High |
| Governance needs | High | Medium | Low |
| Business diversity | Low | High | High |
Evolution Path: Most organisations start centralised, move to federated as they scale, and may eventually become decentralised once AI capabilities are mature throughout the organisation. Don't lock into a model—plan to evolve.
