Enterprise AI

From AI Experimentation to Maturity: Enterprise Priorities for 2026 

By Bastien Aerni, Vice President, Strategy and Technology, GTT

The experimentation phase has ended. For many enterprises, 2025 has been the year AI became embedded in how business is done. Enterprises rolled out their own models or bought enterprise off-the-shelf options, while exploring new ways to serve customers and enhance internal operations.  

The rollout highlighted opportunities, gaps, and enabled those teams to understand the potential the technology can deliver. However, it also became clear that the speed of deployment can bring challenges with AI investment alone not always translate into meaningful and measurable outcomes.

AI’s success relies primarily on how well an organisation understands its own landscape and the KPIs set – this includes data quality, network capacity, operational constraints, integration points and existing governance structures. Misaligned deployments can lead to inconsistent performance, unpredictable costs, and even AI withdrawal.

So, what can we expect as businesses head into the next phase?

Solidifying Structure

 AI adoption is moving from rapid experimentation to structured execution, reflecting the greater maturity that comes with experience.

Businesses are now looking to refine their AI initiatives. They are increasingly concentrating on scalability, security, and dependable data governance. To ensure AI provides value over time, they are becoming more deliberate with the problems it is tasked to solve, the metrics used to measure success, and the processes used along the way.

This move towards a more disciplined approach is closely tied to the advancing regulatory environment. If 2025 was the year of discovery, 2026 is the year of accountability. Compliance and governance expectations are growing globally, and enterprises are preparing for the first wave of formal AI oversight.

Transparency, flexibility, and explainability are essential features of any AI initiative.

How Governance Will Shape Enterprise Priorities

Increasing governance oversight impacts how organisations allocate investment.

Rather than directing budgets primarily towards experimentation, leaders prioritise frameworks and tools that ensure AI is built on flexible and resilient foundations. Strong governance reduces compliance risk, but equally importantly, it improves outcomes. When data quality, security controls, and model transparency are embedded from the start, the likelihood of a stable, sustainable deployment increases.

Innovation and governance are not opposing forces. Instead, governance provides the structure that allows innovation to scale safely. Focus on his level of accountability and flexibility will be true determinants for success over the next year.

As a side effect, mature governance also supports AI initiative rollouts by offering guidance and best-practice on how to use AI tools and therefore optimise team adoption.

New Expectations for Partnerships

As technology stacks expand and regulatory pressures rise, enterprises are also reassessing their partnerships. The traditional model of isolated vendor relationships is giving way to something more interconnected.

Complex AI ecosystems span networks, clouds, data platforms, and regulatory jurisdictions. To navigate this, organisations need partners capable of operating at scale and without boundaries.

This is driving demand for agnostic, adaptable partners who can bridge multiple platforms, regions, and compliance requirements.

Businesses are increasingly deploying global, multi-layered collaboration models. By building flexible partnerships with infrastructure providers, industry specialists, and regulatory authorities, enterprises are aiming to stay agile in the face of shifting regulation and evolving technology.

The priorities of 2026

Quality and speed are coming into balance, as organisations refine their understanding of what successful AI deployment requires.

Governance must be viewed as an enabler, providing the structure needed for confident, transparent, and scalable innovation. Partnerships, too, are evolving, with enterprises recognising that flexibility and interoperability are essential to long-term resilience.

These shifts signal a broader transition. AI is moving beyond the volatility of its early

experimentation phase into a period of more deliberate, strategic progress. Organisations can turn what they learned in 2025 into clearer thinking with stronger foundations, delivered through partnerships designed to withstand change.

The value phase is starting. Make sure you’re best placed to capitalise on it.
