The challenge of AI adoption in the public sector

A recent IDC Spotlight report, based on a survey of 685 public sector respondents, revealed that 72% of participants describe scaling AI from pilot to production as "very" or "quite" difficult. Choosing the right model is only part of the challenge. Agencies must also prepare their data for AI.

Agencies that succeed with AI are building a governed retrieval layer, often called next-generation federated knowledge access, which connects authoritative knowledge to AI agents while maintaining sovereignty, auditability, and public trust.

The pressure to scale AI in the public sector

Public sector organizations worldwide are navigating this difficult intersection: shrinking budgets, expanding regulatory obligations, and rising citizen expectations, while AI redefines what is possible. Governments no longer focus solely on AI adoption but on how to scale it responsibly while maintaining governance and control.

Fiscal pressure is intensifying in many regions. According to a United Nations report, investments in resilient infrastructure and advanced technologies continue to grow. Leaders are called upon to deliver better outcomes with fewer resources, and they are turning to AI to bridge this gap. AI is no longer a discretionary innovative initiative but is becoming a policy and service priority.

The problem of data preparation

The 72% of IDC survey respondents identified the main barriers to AI scalability: skills gaps, security and compliance risks, and data preparation. Traditional data warehouses were designed for periodic analysis of structured and curated data, while agentic AI requires governed and rapid access to a much broader knowledge surface.

This knowledge surface could include policies and procedures, case notes and correspondence, call transcripts, forms, operational logs, and real-time cybersecurity threat signals. Much of this content is unstructured and resides in siloed systems, making it difficult to correlate and analyze. Without governed access to authoritative knowledge, AI applications may produce less reliable outputs, making it harder for agencies to build and maintain public trust.

Legacy data vs. next-generation knowledge access

Traditional data warehouses are designed for reporting and periodic analysis purposes, while next-generation knowledge access is designed for real-time grounding and retrieval for AI. Agentic AI requires a combination of hybrid search (lexical and semantic) and retrieval-augmented generation (RAG) to support agentic workflows and conversational assistants.

The quality of retrieval is fundamental to the success of AI in the public sector. Without a foundation of governed retrieval, customization efforts do not scale. Agencies must consider sovereignty and governance from the beginning of the selection process, as model performance only counts if the technology can operate within the agency's compliance requirements.

Trends shaping the evolution of AI in the public sector

Three converging trends are shaping this evolution: hybrid search as the standard model, open integration protocols, and security and risk controls as safeguarding mechanisms. Together, these capabilities transform search into an AI-ready retrieval service that can keep data in compliant positions, enabling controlled and low-latency access across distributed systems.

When retrieval is governed and consistent, the benefits extend throughout the organization. Agencies can expect a unified operational view that breaks down data silos, improving visibility and enabling faster, more informed decisions. Additionally, they can expect efficiency gains from consolidating fragmented search and retrieval tools, reduced compliance exposure through integrated permission filters, redaction, and audit logs, and faster production time for AI use cases across various sectors.

Priorities for public sector leaders

The IDC report indicates a clear strategy for public sector leaders: focus on building a governed retrieval layer that connects authoritative knowledge to AI agents. This approach not only facilitates AI adoption but also ensures that agencies can operate in compliance and maintain public trust. Scaling AI in the public sector requires a holistic approach that considers data, governance, and compliance from the outset.

Concrete results and use cases in the public sector

The adoption of a governed retrieval layer is already producing tangible results in various public sectors. For example, social case management systems can automatically integrate historical notes, interview transcripts, and procedural guidelines to provide operators with contextual recommendations. In security agencies, real-time analysis of threat signals can be correlated with historical intelligence databases to identify previously invisible patterns.

Another promising use case is in public healthcare, where the integration of electronic health records, therapeutic protocols, and medical research can support faster and more accurate clinical decisions. These examples demonstrate how governed access to knowledge can transform complex processes into more efficient and reliable workflows.

Implementation challenges and practical solutions

Despite the evident benefits, implementing these systems presents significant challenges. 68% of IDC survey respondents reported difficulties in integrating data from heterogeneous sources, while 57% identified the lack of internal skills as the main obstacle. To overcome these barriers, many agencies are adopting incremental approaches, starting with specific use cases and scaling gradually.

A practical solution involves integrating open standards and frameworks to ensure interoperability and quality. Agencies must also develop internal capabilities to manage and continuously optimize AI systems, adopting a mindset of continuous improvement.

The role of hybrid search and RAG

Hybrid search, which combines lexical and semantic approaches, is emerging as the standard for knowledge retrieval. This methodology overcomes the limitations of traditional keyword-based search engines, allowing for understanding the context and intent behind queries. Retrieval-augmented generation (RAG) further enhances this capability, combining search results with generative models to produce more accurate and contextualized responses.

The integration of these technologies into agentic workflows is revolutionizing applications such as conversational assistants for citizens, decision support systems for public officials, and predictive analytics platforms for strategic planning. The key to success lies in the ability to keep these systems aligned with the specific needs of the public sector, through the integration of vertical knowledge and domain expert feedback.

The path to widespread adoption

To achieve widespread adoption of AI in the public sector, it is essential to adopt a strategic approach that integrates technology, governance, and training. This requires the creation of an ecosystem of interoperable solutions, supported by open standards and certification frameworks to ensure quality and security. Agencies must also develop internal capabilities to manage and continuously optimize AI systems, adopting a mindset of continuous improvement.

Finally, collaboration between the public sector, industry, and academia will be crucial to addressing the most complex challenges. Through strategic partnerships, agencies can access specialized expertise, advanced technological resources, and consolidated best practices. This collaborative approach will not only accelerate AI adoption but also ensure that the solutions developed are robust, scalable, and aligned with the evolving needs of public service.

The evolution of AI in the public sector represents a transformative opportunity to improve operational efficiency, service quality, and decision-making capacity. However, realizing these benefits requires a comprehensive approach that addresses the challenges of data preparation, governance, and compliance. Through the adoption of a governed retrieval layer and the integration of advanced technologies such as hybrid search and RAG, agencies can build reliable and scalable AI systems that maintain public trust and meet regulatory needs.

As agencies continue to navigate this complex landscape, it is fundamental to maintain a balance between innovation and governance, ensuring that technological advances are always aligned with the fundamental values of public service. Only through this balanced approach can the full potential benefits of AI for citizens and the communities we serve be realized.
