AI can help someone finish a task faster without making the company produce more valuable output per hour. Company-wide productivity depends on the whole workflow, how widely and intensively AI is used, the investments and organizational changes around it, and whether saved time becomes additional output. Evidence so far is mixed: some firm-level studies report gains, but clear economy-wide AI-driven productivity growth has not yet emerged in the indicators reviewed by the International Labour Organization (ILO).
Why a faster task may not raise company productivity
A task study and a company productivity measure answer different questions. A task study might ask whether a worker drafts a document or completes a defined coding task faster. A company-level measure asks whether the organization produces more output, or more valuable output, relative to its inputs across a larger operation.
If AI speeds up one step but the rest of the process stays the same, the whole operation may not finish more work. For example, faster drafting may have little effect on delivery time if approvals or quality checks still set the pace. The Federal Reserve describes this general problem as bottlenecks and adjustment costs that can erode upstream task gains; these workflow examples illustrate the mechanism rather than report separate measured effects.

The distinction matters because task-level results can be striking without serving as a forecast for a whole company. The ILO’s May 2026 brief reports typical task-level productivity gains of 10–70 per cent across the studies it reviewed, with stronger effects for less experienced workers and well-defined, text-intensive tasks. That range is not a promise of the same gain in company output.

What can prevent task gains from scaling?
AI is adopted unevenly and sometimes only lightly
Having access to an AI system is not the same as using it intensively across the work that determines a firm’s results. The Federal Reserve notes that survey measures of adoption may not reveal how deeply AI is embedded in work, and reported adoption tends to be associated with firm size. The ILO likewise finds that firm-level evidence is mixed, with gains concentrated in larger, digitally advanced enterprises and many firms reporting little measurable effect beyond pilots.
AI’s usefulness also varies with the work a business does. The OECD’s November 2024 report explains that current capabilities apply most readily to cognitive, knowledge-intensive tasks; physical work is less directly affected. A company with many suitable tasks may have more opportunities than one whose core production depends on work AI does not readily assist.
The surrounding work may need to change
AI access alone does not redesign a process. The ILO identifies work reorganization and skills as relevant conditions for gains to scale. The European Investment Bank (EIB) highlights software, data, and workforce training as complementary investments associated with realizing benefits. If staff cannot access reliable data, lack the skills to use the tools effectively, or must fit AI output into a process designed for manual work, the technology may improve isolated activities without transforming production.
Saved time does not automatically become more output
A worker finishing a task sooner creates capacity, but the productivity effect depends on what happens next. The ILO’s June 2026 review says workers report time savings amounting to a few per cent of working hours, but those savings have not yet translated into higher measured output, earnings, or employment in the evidence it reviews. That finding does not establish how every company uses saved time; it shows why reported time savings should not be treated as equivalent to measured business output.
Implementation can absorb some of the benefit
Companies may need to adjust processes and integrate AI into existing work. During that adjustment, review, handoffs, and other constraints can limit the value of faster individual tasks. The Federal Reserve identifies adjustment costs and bottlenecks as reasons a task-level improvement may not become a proportional firm-level gain.
What the evidence says—and what it does not
Results vary because studies measure different outcomes, populations, and time periods. The figures below are not directly interchangeable: some describe worker performance on tasks, while another reports a firm-level labour-productivity estimate.
| Source and scope | Reported result | How to interpret it |
|---|---|---|
| ILO, May 2026 review of task-level studies | Typical gains of 10–70 per cent across the studies reviewed | Task-level results; strongest for less experienced workers and well-defined, text-intensive tasks. Not an estimate of company-wide productivity. |
| OECD, November 2024 summary of worker studies | 14% for customer-service agents, nearly 40% for business consultants, and more than 50% for software programmers | Worker-level performance results from studies summarized by the OECD, not comparable estimates of company-wide productivity. |
| EIB Working Paper 2026/02, published 13 January 2026 | AI adoption associated with a 4% increase in labour productivity in the paper’s analysis | Matched EIBIS–ORBIS firm-data analysis covering more than 12,000 non-financial firms in the EU and US. The paper attributes the result to capital deepening rather than job losses and finds gains concentrated in medium and large firms. |
The EIB result is important counterevidence to the claim that AI has no firm-level productivity effect. It is a study-specific finding, not a guaranteed return for any individual company. Meanwhile, the ILO’s May 2026 brief says clear AI-driven productivity growth had not yet appeared in official aggregate statistics. Those findings can coexist: a positive result in a particular firm-level analysis does not by itself establish a broad change in sector or economy-wide productivity.
The Federal Reserve’s July 2026 note reviews publicly available indicators and finds sector productivity trends relatively consistent over the period it analyzes, even though highly AI-exposed sectors appeared to have stronger productivity. It cautions that differences that predate AI make attribution difficult. The note also describes a buildout phase, not proof that broad productivity effects will never materialize.

Aggregate productivity combines businesses with different sizes, sectors, tasks, and adoption levels. If AI helps a subset of knowledge-intensive work while other activities change little, the effect on a whole sector or economy can be modest. Adoption is also incomplete, and shifts in demand or the distribution of activity between sectors can affect aggregate results. The OECD’s 2024 report discusses these aggregation mechanisms and presents widely varying projections, which depend on assumptions and time horizons.
Timing and measurement add uncertainty. General-purpose technologies can take years to spread and to be paired with complementary investments. The Federal Reserve notes that intangible investment and difficulties measuring service-sector output complicate efforts to identify AI’s contribution. A local improvement may therefore be real before it becomes visible in broad official statistics—or may not be large enough to stand out from other changes.
Historical adoption figures should not be mistaken for current rates. The OECD’s November 2024 report cited statistics showing around 5% of US firms adopted AI in 2024 and 8% of EU firms in 2023. These are dated snapshots reported in that publication, not current adoption estimates.

Before applying a reported percentage to a business, check what it actually measures. A result about task completion time is not the same as a result about company output per hour, and neither automatically establishes lower costs or higher revenue.
- Unit: Is the claim about a task, worker, team, firm, sector, or economy?
- Outcome: Does it measure speed, quality, output per hour, revenue, costs, earnings, or total factor productivity?
- Population: Was the evidence drawn from early adopters, a single occupation, a worker survey, or firms across industries and sizes?
- Method: Is it an experiment, a survey, a firm-level association, or a causal analysis? What other changes could explain the result?
- Time horizon: Does it capture a pilot or immediate task effect, or results after implementation and diffusion?
- Complementary inputs: Were software, data, training, workflow redesign, or other organizational investments part of the change?
- Capacity: Did saved time result in more completed output or another measurable business outcome?
For a company evaluating its own use, compare a defined process before and after implementation. Track both the task AI is meant to improve and the outcome the business cares about—for example, completed work per hour or end-to-end turnaround time. Record the relevant workflow changes and inputs too, so a faster task is not mistaken for a company-wide improvement when a different constraint still governs the result.
