Enterprise Architecture (EA) plays a strategic role in modern organisations by bridging business objectives with technological capabilities. As companies operate in increasingly complex environments, the challenges faced by EA multiply. Among the key challenges are the decentralisation of knowledge, data quality, closer integration with business and technology, building resilient organisations, as well as the integration of new technologies like artificial intelligence, cybersecurity management, and environmental sustainability.

1. Decentralising Knowledge and Enhancing Collaboration

Excessive centralisation of knowledge among a few experts can create bottlenecks and hinder organisational agility. One of the main challenges for modern EA is to facilitate the decentralisation of knowledge through collaborative platforms and shared documentation tools. This allows cross-functional teams to access information and make decisions more quickly, thus making the organisation more responsive and resilient. According to Gartner, decentralised decision-making enhances organisational agility by empowering business units .

2. Improving Data Quality in Repositories

The data quality of repositories is critical for decision-making. EA must ensure that data is accurate, accessible in real-time, and consistent across different systems. A strict governance approach and automated integrity mechanisms are required to guarantee high data quality in increasingly digitised and interconnected environments. McKinsey emphasises that clean and accessible data is a key enabler for real-time insights and operational efficiency .

3. Bringing Business and Technology Closer Together

Moving out of the "ivory tower" and getting closer to business units and technology teams is essential for enterprise architects. The role of EA is to bridge business strategy and technical execution. Close collaboration ensures that technological capabilities are aligned with real user needs, fostering innovation and flexibility in the solutions developed. Harvard Business Review highlights how enterprise architects must work closely with both business and tech to create pragmatic, value-driven solutions .

4. Building an Antifragile Organisation

The concept of antifragility, which suggests that systems grow stronger when exposed to disruptions, has become central to modern EA. By designing flexible, modular, and resilient architectures, such as microservices instead of monolithic systems, businesses can better adapt to external shocks, whether economic, technological, or environmental. Nassim Nicholas Taleb's book Antifragile provides the theoretical foundation for this approach, encouraging organisations to not just withstand disruptions but to thrive because of them .

5. Incorporating AI and Emerging Technologies

The integration of artificial intelligence and automation presents a major opportunity for EA but also a challenge in terms of infrastructure, algorithm management, and data ethics. Enterprise architects need to design flexible infrastructures that can accommodate these innovations while minimising risks. Gartner's research on technology trends indicates that AI integration is a key driver of competitive advantage, but it requires careful orchestration within the EA .

6. Security and Risk Management

Cybersecurity is now a core concern for enterprises, with an increasing number of cyberattacks and tighter regulatory pressures (e.g., GDPR, CCPA). EA must ensure that systems are designed with a security-by-default approach, while also integrating business continuity and disaster recovery solutions. According to the European Commission, adopting robust cybersecurity frameworks within EA not only protects the organisation but also ensures compliance with evolving regulations .

7. Interoperability and Legacy Systems

Enterprises often have to manage legacy systems, which, though outdated, remain critical to operations. Integrating these systems with newer cloud or digital solutions is an ongoing challenge. EA must develop solutions to maintain interoperability while planning for a gradual transition toward modern systems. TOGAF, widely used as a framework, provides guidelines on managing legacy systems while maintaining business continuity .

8. Sustainability and Environmental Standards

Integrating sustainability principles into the technological architecture is becoming a priority. EA must include strategies to reduce energy consumption, lower the carbon footprint of data centers, and promote circular economy practices in managing technological infrastructures. Gartner’s recent reports indicate that sustainable IT practices are increasingly becoming a criterion for success in enterprise architecture planning .
