Enterprises are moving beyond GenAI demonstrations, but Deloitte’s latest research shows that industrial-scale deployment remains difficult. In Deloitte’s 2026 enterprise AI study, only 25% of respondents said they had moved at least 40% of their AI pilots into production. The finding does not mean companies are doing nothing with AI; it means many have not yet made it reliable, governed, integrated and economically worthwhile.
The bottleneck is increasingly less about access to a capable model and more about skills, data, workflow ownership, controls, infrastructure and proof of value.
What Deloitte actually surveyed
Deloitte’s latest study is broader enterprise AI research, not a survey limited exclusively to generative AI. It covered 3,235 business and IT leaders in 24 countries. Respondents were director-level through C-suite, directly involved in their organizations’ AI initiatives, and the fieldwork took place in August and September 2025. Deloitte published the findings in 2026.
Its international summary reports that 25% of respondents had moved at least 40% of their AI pilots into production. Deloitte’s US report also says the number of companies with at least 40% of AI projects in production was expected to double within six months. That is a forecast of planned expansion, not proof that the increase had already happened.

#1 Best Overall
Earlier Deloitte studies used different samples and definitions. A Q4 2024 wave covered 2,773 AI-savvy business and technology leaders in 14 countries and six industries; the Q3 2024 wave covered 2,770 respondents. Those surveys focused more specifically on generative AI. Their results should illuminate a recurring scale-up problem, not be treated as a precise year-over-year trend.
All of these figures are respondent-reported. They are not an audited count of live systems, independently verified financial results or a random sample of every company. The respondents were already engaged with AI, so organizations with no AI activity are underrepresented.
Deloitte’s international 2026 summary and US report provide the methodology and findings.
The production gap is a ladder, not a single statistic
“Deployed” can describe very different levels of operational maturity. A company can give employees access to an assistant without changing a business process or proving a financial benefit.
| Stage | What it means | Evidence of maturity |
|---|---|---|
| Experiment | A proof of concept, sandbox, hackathon or limited internal test | Interesting output, but no operational commitment |
| Pilot | A controlled trial for a defined group or workflow | Named users, scope and test objectives |
| Production | A live system used in an operational process | Support owner, monitoring, access controls, incident handling and a release process |
| Scaled production | Use broad enough to affect material volume, cost, revenue, service or workforce activity | Capacity planning, repeatable controls and measurable business outcomes |
| Transformation | AI changes the process, roles, controls or economics | Redesigned operating model rather than an added interface |
Deloitte’s 2026 25% measure uses the share of pilots moved into production. Deloitte’s Q3 2024 generative-AI research found that nearly 70% of respondents had moved 30% or fewer GenAI experiments into production, while only 35% were tracking ROI. Because the samples, dates and wording differ, these numbers cannot form a clean trend line. Together, they show that moving from experimentation to dependable scale has remained difficult.

Six reasons enterprise AI pilots stall
1. Skills and operating-model gaps
Deloitte’s latest report identifies insufficient worker skills as the biggest barrier to integrating AI into existing workflows. Leaders also reported feeling less prepared in infrastructure, data, risk and talent than in overall AI strategy.
The shortage is not limited to people who can call a model API. Production teams need AI and data engineers, evaluators, security specialists, product managers and domain experts who understand how work is actually performed. They must define acceptable outputs, handle exceptions and decide when a human must intervene.
Training employees to use a chatbot is therefore not the same as workforce transformation. A production operating model specifies who owns the system after the pilot team leaves, who reviews exceptions, how work is evaluated and what happens when the model is wrong. Deloitte’s US findings are available at its enterprise AI report.
2. Data readiness and integration
A demonstration can use a clean document set. A production application must work with duplicate records, stale knowledge, unstructured files, inconsistent permissions and authoritative systems that were never designed for AI retrieval.
- Identity and retrieval controls must ensure that a user receives only information they are entitled to see in that context.
- Metadata, lineage, taxonomy and document ownership must be clear enough to identify the right source.
- Data may require residency, retention, redaction and deletion controls.
- The application may need reliable connections to ERP, CRM, ticketing, records-management and workflow systems.
Adding a model to a process is not the same as making the process AI-ready. Deloitte discusses data preparation, diverse sources, governance and self-service access in its analysis of scaling AI at the data value chain.
3. Governance, risk and compliance
In Deloitte’s Q3 2024 GenAI survey, the leading deployment barriers included regulatory-compliance concerns (36%), difficulty managing risks (30%) and the lack of a governance model (29%). These are historical, wave-specific figures, not 2026 measurements, but they show how early risk concerns became a production constraint.
At scale, governance has to be implemented in the system and workflow rather than left as a committee charter. Practical controls include:

- Risk classification that distinguishes an employee aid from a system influencing a consequential decision.
- Human approval for high-impact actions and clearly defined escalation paths.
- Logging of prompts, outputs, retrieved data and tool calls.
- Testing for hallucination, bias, privacy leakage, prompt injection, jailbreaks and unsafe tool use.
- Change control when a model, prompt, retrieval index or connected tool changes.
- Incident response, rollback and evidence that can be reviewed by auditors, regulators, customers or affected workers.
Deloitte says governance differentiates organizations that scale successfully from those that stall. Controls can still slow delivery when they are detached from the workflow, so the objective is enforceable, proportionate control rather than paperwork alone. See the Q3 2024 findings.
4. ROI is often asserted before it is measured
Deloitte’s 2024 research found that almost all organizations reported measurable ROI in their most advanced GenAI initiatives, with 20% reporting ROI above 30%. Its Q3 research, however, found that only 35% were tracking ROI. These statements can coexist: a team may report benefits without using a consistent, formal measurement system.
A credible business case measures the cost of a completed outcome, not just the price of a model call or the number of minutes saved in a draft. Costs can include inference, retrieval, data preparation, security, compliance, human review, integration, support, change management, vendor minimums and cloud consumption. Gross time savings may disappear when verification or exception work is added elsewhere.
Use a scorecard containing:
- The business outcome and a documented baseline.
- All AI-related costs, including review and support.
- Quality and error thresholds.
- Human-review hours and escalation rates.
- Adoption and meaningful usage, rather than logins alone.
- Security, privacy and compliance incidents.
- Explicit continue, redesign or stop criteria.
Where feasible, compare with a control group or a pre-AI period and track cycle time, completed work, error rates, customer satisfaction, revenue, loss avoidance and risk reduction. Deloitte’s ROI findings appear in its enterprise GenAI research and 2024 enterprise report.

5. Infrastructure and cost control
Deloitte’s separate infrastructure survey describes “AI factories”: sustained infrastructure for many workloads rather than isolated prototypes. Nearly a quarter of respondents expected to deploy AI factories within three years, and 73% expected at-scale deployment in that period. These are expectations, not guarantees. Respondents also identified organizational and business challenges (48%), regulatory pressures (48%) and talent gaps (40%) as potential sources of delay.
Production architecture must account for latency, throughput, availability, disaster recovery, model routing, fallback behavior, GPU and storage capacity, token budgets, caching, batch versus real-time inference and observability. Finance teams also need cost allocation by application, business unit, user and use case, with a plan for peak or agentic workloads.

6. Workflow and change-management failure
A pilot may produce a useful draft while leaving approval, exception handling and the underlying records process untouched. Employees then gain another screen but not the authority, time or incentives to change how work is done.

A technically live system can remain unused if workers do not trust it or if accountability is unclear.
Why a successful demo breaks in production
Consider an internal document-summary prototype. In a demonstration, a model summarizes a small set of approved files. Production requires single sign-on and role-based access, permission-aware retrieval, source citations, evaluation data, logging, escalation for uncertain answers, support coverage, retention rules, cost limits and a process for correcting bad source documents.
Each requirement exposes work that the demo hid. The model may be unchanged, but the application now has to interact safely with identity systems, records, monitoring and people. That is why the deployment problem is architectural and organizational as much as it is about model quality.

Choosing an implementation path
| Approach | Best fit | Main trade-off |
|---|---|---|
| Packaged productivity assistant | Organizations standardized on an existing collaboration and identity suite | Fast integration, but less control over specialized behavior and architecture |
| Cloud AI platform | Teams building custom applications and needing managed models, runtime and security | Power and flexibility come with consumption costs and cloud coupling |
| Custom application | Proprietary workflows, unusual controls or competitive differentiation | More control, but substantially more engineering, evaluation and support work |
| Governance and observability layer | Regulated or multi-model environments | Improves evidence and control, but does not fix poor data or process design |
| Hybrid delivery | Most enterprises combining purchased models with business-specific workflows | Balances speed and control, while requiring clear ownership across vendors and internal teams |
Centralized platforms can improve policy consistency, procurement leverage and incident response. Federated ownership can improve domain fit and experimentation. A practical compromise is centralized guardrails and shared services with federated use-case ownership.
Retrieval-augmented generation is generally preferable when the problem is access to changing enterprise knowledge. Fine-tuning can help with style, classification or repeatable behavior, but neither approach automatically solves stale data, unauthorized access or hallucinations.
Agentic systems need extra safeguards because they can call tools, create cascading errors, hide state, run up costs or act on prompt-injected content. “Agent deployed” is not equivalent to “agent controlled.”
What executives should measure after launch
A production dashboard should connect operational outcomes to risk and economics:
- Completed work, cycle time and error rate against the baseline.
- Quality scores and the percentage of outputs requiring correction.
- Human-review time, exception volume and escalation rate.
- Adoption by the intended users and workflow completion, not merely logins.
- Inference, retrieval, infrastructure, support and compliance cost per completed outcome.
- Availability, latency and fallback frequency.
- Privacy, security, policy and safety incidents.
- Customer, employee or regulatory impact where relevant.
Review the scorecard at predefined gates. A system that meets usage targets but misses quality, cost or safety thresholds is not ready for further scale.
What Deloitte’s findings mean
Deloitte’s evidence describes a transition rather than a retreat from AI. Enterprises are expanding access and planning larger deployments, but many have not industrialized the work around the model. The organizations most likely to reach durable production will treat AI as an operating-model and control-system transformation: clean and permissioned data, accountable owners, measurable outcomes, enforceable governance, resilient infrastructure and redesigned workflows.
The central question for a CIO or finance leader is therefore not “Which model should we buy?” It is “Which business outcome can we operate safely, measure honestly and improve continuously?”
