A shorter task time is evidence about that task; it is not, by itself, proof of higher company-wide productivity or lower labor costs. If you are asking, “How can I tell if AI is actually saving my team time?” measure actual use and time spent. If you are asking, “Does time saved with AI translate into cost savings?” check whether spending or labor costs actually fell.
What counts as an AI productivity gain?
“Productivity” can refer to several different outcomes. Before measuring, say exactly which one you mean and at what level: a task, worker, team, firm, sector, or economy. Evidence at one level does not automatically establish a result at another.

- Task speed: time to complete a defined task, such as drafting a response.
- Output per unit of time: completed cases, reports, or other work per hour.
- Quality-adjusted output: work completed that also meets a defined standard for accuracy, completeness, or usefulness.
- Worker time use: how much time people spend on activities, whether or not they produce more total work.
- Revenue or cost: financial outcomes for a team or business; these need to be measured directly rather than inferred from task speed.
- Aggregate productivity: an economy- or sector-level measure that cannot be read directly from an individual pilot.
Use a metric that matches the claim. If the claim is “agents resolve more cases per hour,” measure resolved cases per hour. If the claim is “the tool lowers operating costs,” examine the relevant spending or labor costs. A task benchmark or a report of time saved cannot stand in for those broader outcomes.
How can you tell whether AI is actually saving your team time?
Measure time on the work in question before and after access to AI, while distinguishing access from actual use. Record which workers used the tool, how often, for which tasks, and within what workflow. Otherwise, a result among frequent users can be mistaken for the effect of simply making a tool available to everyone.
#1 Best Overall
A six-month experiment by Dillon, Jaffe, Immorlica, and Stanton, published as NBER Working Paper 33795 in 2025, covered 66 firms and 7,137 knowledge workers. In the second half of the experiment, the 80% of treated workers who used the AI tool spent two fewer hours on email each week. The study did not detect changes in the quantity or composition of workers’ tasks from individual-level access. The email result is a measure of time use among users in that period—not a measured increase in output or a direct labor-cost saving.
For a team-level time study, use consistent task definitions and a consistent logging method across the baseline and comparison periods. Note whether time is self-reported, captured through workflow data, or measured another way. Also record whether workers shifted saved time to review, coordination, or other tasks; less time in one activity does not necessarily mean fewer total work hours.
How do you attribute a change to AI?
A before-and-after comparison can show that performance changed after deployment, but it cannot by itself establish that AI caused the change. Staffing, workload, seasonality, process changes, or the kinds of tasks assigned may have changed too.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Set a baseline: define the tasks, population, time window, and outcome before rollout.
- Choose a comparison: when feasible, use a randomized rollout or a well-designed quasi-experiment with a contemporaneous comparison group.
- Document implementation: record the tool and workflow, who received access, who used it, and any changes made during the study.
- Compare like with like: check that task mix, staffing, and measurement methods are sufficiently comparable across groups and periods.
- State the scope: describe the studied workers, tasks, implementation, and follow-up period rather than extending the finding to other settings without evidence.
Experimental designs involve a trade-off. Controlled studies can strengthen causal attribution, while field conditions better reflect routine work but may make it harder to isolate the tool’s effect. The OECD’s 2025 review of experimental evidence on generative AI discusses this tension between internal validity and external validity. A credible result is still a result for the studied setting, not a universal rate of return.
Why measure quality alongside speed and volume?
Faster completion can be a real operational improvement, but it matters whether the work is accurate, useful, and accepted. Pair speed or volume with a quality check suited to the task—for example, error rates, rework, expert review, resolution quality, or customer outcomes.
In Generative AI at Work, Brynjolfsson, Li, and Raymond studied 5,179 customer-support agents at one Fortune 500 software company during a staggered rollout. The NBER summary reports a nearly 14% average increase in issues resolved per hour; gains were larger for the least-skilled and least-experienced workers, with a 35% increase for that subgroup. Researchers also tracked customer satisfaction and found no significant change in it alongside the throughput increase. This is evidence from a particular support setting, not a general AI productivity rate. It illustrates why throughput and quality should be reported together.
How should results be broken out across workers and tasks?
An average can conceal who benefits, who does not, and where the tool creates extra work. Where sample sizes support it, report results by relevant groups identified in advance, such as task type, worker experience, or skill level. Avoid relying on tiny subgroup samples or selecting groups after seeing the results without labeling that analysis exploratory.

The customer-support study above found larger gains among novice and lower-skilled workers, while experienced or highly skilled workers saw little or no benefit. That variation matters for decisions about training, workflow design, and where to deploy a tool; a single team average would obscure it.
Does time saved with AI translate into cost savings?
Not necessarily. Time released may be used for more output, absorbed by review or coordination, or left as unused capacity. It becomes a financial saving only when a defensible cost or spending outcome is observed—for example, a documented reduction in paid hours or another relevant expense. Do not multiply reported minutes saved by an hourly wage and present the result as money saved unless the organization actually reduced that cost and the calculation’s assumptions are justified.
The International Labour Organization’s June 2026 review, The impact of GenAI on jobs, productivity and work organization: a review of the empirical evidence, draws on experiments, firm-level data, platform studies, and worker and firm surveys in Australia, Denmark, Germany, Korea, Kuwait, the United Kingdom, and the United States. It reports that worker-reported time savings of a few per cent of working hours have not yet translated consistently into measured output, earnings, or employment. The ILO describes the evidence as showing that “productivity gains are real albeit often unverified and uneven.”

Work that becomes faster in a pilot may be only one part of a firm’s production process. Adoption may be uneven, other tasks may become bottlenecks, and measurement at the firm or economy level captures more than the performance of AI-assisted tasks. Institutional reviews therefore distinguish task-level evidence from firm-level and aggregate productivity measures.

That is a broad synthesis of task findings, not a forecast or an expected effect for a particular organization. The OECD’s 2026 Compendium of Productivity Indicators likewise treats micro-level evidence, firm evidence, and aggregate measures as distinct.
Longer-run figures should also be labeled as projections, not realized results. The OECD’s 2026 compendium reports a cited projection attributed to Acemoglu (2024) of roughly 0.12 percentage points added to the United States’ average labor-productivity growth rate over ten years. It also reports a cited OECD estimate attributed to Filippucci et al. (2025) of 0.2–1.3 percentage points in average annual labor-productivity growth over ten years for the G7. Neither figure is an observed saving for a business or a guaranteed productivity outcome.
What should a useful AI productivity report include?
Use a compact report that makes the claim, evidence, and scope visible in the same place. For each result, include:
- Claim and unit: what changed, and whether the unit is a task, worker, team, firm, sector, or economy.
- Metric and quality check: the quantity, speed, time, or financial outcome measured, plus the relevant quality or outcome measure.
- Baseline and comparison: the dates or periods, comparison group, and design used to estimate the change.
- Exposure: who had access, who used the tool, how often, for which tasks, and under what workflow conditions.
- Result distribution: the average and meaningful differences across pre-specified worker or task groups, where sample sizes allow.
- Limitations: applicable constraints such as short follow-up, pilot scale, self-reported time, changing model versions, task selection, adoption, or uncertain generalizability.
- Financial interpretation: whether costs, spending, revenue, or earnings were measured directly—or whether the finding is only about time, output, or quality.
This format keeps an observed task result from turning into a broader claim the evidence does not establish.
