Automation can help manufacturers relieve labor and cost pressures when it targets a specific, repetitive constraint—such as machine tending, parts handling or inspection—and the company measures results against a clear baseline. It can increase capacity, consistency or safety, but it does not guarantee lower costs or fewer employees. The best projects connect a real operating need to a viable business case and a plan for the people whose work changes.
How can automation help manufacturers manage labor and cost pressures?
Automation shifts selected tasks from people to equipment or software. In manufacturing, that can mean a collaborative robot tending a machine, an autonomous mobile robot moving material, or machine vision checking a product. It is not limited to installing a robot arm: the useful question is which step in a process is repetitive, constrained, difficult to staff, unsafe, or inconsistent—and whether automating that step improves the operation enough to justify its full cost.
When the fit is good, automation can let a machine run for more of the available day, increase throughput, improve consistency or yield, and provide operational data. It may also reduce exposure to repetitive or ergonomically difficult work. These are possible outcomes, not automatic ones. They depend on the task, integration, maintenance, demand for the added output and the way the rest of the production process is organized.
Automation is therefore a targeted capacity and process decision, not a general-purpose cure for rising labor costs. A system that produces faster than the next process can accept may only move the bottleneck. A cell that requires frequent intervention may not free as much labor as its cycle time suggests. And additional output has limited economic value if orders are not available or if quality problems persist.

How do manufacturers use automation to address labor shortages?
Manufacturers can automate defined portions of jobs that are repetitive and stable, allowing existing employees to cover other work or supervise an automated cell. Examples include loading and unloading a machine, moving parts between operations, or inspecting a repeatable feature. The objective need not be to remove a position: it may be to keep production running with a constrained shift, relieve physical strain, or move skilled staff to work that requires judgment and flexibility.
In one NIST Manufacturing Extension Partnership (MEP) case, AMG Industries redeployed employees from a repetitive exhaust-tip operation to other needed areas after introducing a collaborative robot. In a separate MEP case, Ohio manufacturer Area 419 automated parts handling on a fifth-axis machine. Its operations vice president said the company maintained a single staffed shift while the machine ran during the remaining 16 hours of the day. Within eight months, the company purchased another machine with the same automation and hired an operator to manage that cell. These examples show possible workforce responses, not typical or guaranteed outcomes.
Before choosing equipment, define how affected employees will be involved and what work is expected to change. That can include training people to load, monitor, troubleshoot or maintain the cell, or redeploying them to another production need. The plan should account for safety and for the fact that a new automated process can change responsibilities even if headcount does not change.
What do current U.S. labor-cost figures say—and not say?
The U.S. Bureau of Labor Statistics (BLS) reported that manufacturing labor productivity increased 2.0% in 2025, while manufacturing unit labor costs increased 2.3% and hourly compensation increased 4.3%. In BLS terms, labor productivity is output per hour; unit labor costs are hourly compensation divided by labor productivity. Compensation growth tends to raise unit labor costs, while productivity growth tends to lower them.

The annual figures do not mean every plant had the same experience, nor do they show that automation caused either change. BLS industry-level estimates show variation: unit labor costs rose in all 20 covered three-digit NAICS manufacturing industries in 2025, at an average rate of 4.5%, and in 71 of 80 covered four-digit industries. Those industry series are separate from the all-manufacturing annual figures above.
The quarter-end figures tell a different, shorter-period story. In the fourth quarter of 2025, manufacturing labor productivity fell 1.9% and unit labor costs rose 8.3%, both at seasonally adjusted annual rates. These annualized quarter-to-quarter changes should not be mistaken for full-year or year-over-year changes. BLS also cautions that manufacturing output measures and nonfarm business output measures use different concepts, sources and methods, so they are not directly comparable. The statistics describe economic results; they do not isolate the effect of automation at individual factories.
Which processes are sensible candidates for automation?
Start with the process constraint rather than a preferred technology. NIST MEP recommends assessing operations, prioritizing opportunities, building a business case aligned with company strategy, connecting with integrators and vendors, and measuring results. The following screening questions turn that guidance into a practical comparison; they are a decision checklist, not a published NIST scoring system.
- Is the work repeatable and stable? Repeated motions and consistent part presentation are generally easier to automate than tasks that change substantially from cycle to cycle. Frequent product or process changes may require additional tooling, programming or operator attention.
- What constraint will be relieved? Identify waiting, downtime, a labor coverage gap, a handling delay, or a quality problem. Specify where it occurs and how often, rather than describing the goal only as “more automation.”
- Can the result be measured? Choose relevant measures such as parts per hour, machine running time, defects, yield, labor hours per unit or safety exposure. Pick measures before installation so a change can be compared with the prior process.
- What happens to the people and the surrounding process? Identify the intended redeployment, training or cell-operating role, and check whether material supply and downstream operations can absorb the changed rate.
- Can the system accommodate the product mix? Account for changeovers, part variation and expected process changes, not only the best-running product or an ideal cycle.
- What is the full cost to operate? Include equipment and integration, as well as maintenance and ongoing operating costs. A purchase price alone does not describe the investment required to keep a cell productive.
- Does the measured return meet the business case? Compare the investment with documented, sustained operational gains and a defined payback period; do not use a vendor’s best-case capacity claim as the plant’s expected return.
How should a manufacturer build and test a business case?
1. Walk the process and establish a baseline
Observe the task under ordinary operating conditions. Record the output and labor or machine time that matter to the constraint, along with interruptions, quality losses, changeovers and required operator involvement. The baseline should describe actual performance over a representative period, not a single unusually good shift. Also establish whether the business has demand for additional capacity and whether the next process can use it.

2. Compare the problem with the candidate solution
Write down what the proposed equipment will do and what it will not do. For example, automating parts handling may reduce time spent loading a machine, but it does not by itself solve a shortage of raw material, poor part quality, downstream congestion or every staffing issue. Identify the interfaces between the automated task and people, equipment and material flow. A qualified integrator can help assess those interfaces and adapt a solution to the actual process.
3. Estimate the full investment and operating effect
Build a cost estimate that includes the system, integration and expected operating and maintenance costs. Then estimate measurable benefits against the baseline: additional saleable output, reduced scrap or rework, capacity made available, or labor time redirected to other needed work. Separate benefits that are cash savings from benefits that create capacity or avoid a future constraint; they are not interchangeable unless the business can use or monetize the capacity.
A simple payback calculation is the initial investment divided by the expected net benefit per period. Use it as a planning aid, not a promise. The answer changes if the system is unavailable, output cannot be sold, staffing remains necessary, or production savings do not materialize. State the assumptions, time period and benefits included so leaders can compare projects on the same basis.

4. Pilot where practical, then verify performance
A trial can reveal intervention needs and integration problems before a larger commitment. AMG used a three-month robot trial through a loaner arrangement before purchasing equipment for the task. That is an example of one company’s route to testing, not evidence that the same program or terms are available to every manufacturer. Where a pilot is possible, agree in advance on the baseline, success measures, safety review and decision point.

After installation, measure the same indicators used to establish the baseline. Compare actual performance with the business case, investigate gaps and account for ramp-up or process changes rather than attributing every difference to the equipment. Continue tracking whether the intended workforce and quality outcomes are occurring as well as output.

AMG Industries: collaborative robot for repetitive production
NIST MEP describes AMG Industries using a collaborative robot on a repetitive exhaust-tip production task, with MEP engineers and automation specialists helping the company observe the work and install and program a Universal Robots system. The robot averaged 276 parts per hour, compared with 200 manually, a reported 38% increase for that operation. AMG initially forecast an 11.5-month payback; after productivity and labor savings, the company reported a realized payback period of six and a half months. After a three-month trial, it purchased a UR10e for the role. The loaner arrangement was reported to save the company $15,000 by enabling a trial before purchase.
Those figures describe AMG’s specific task and implementation. The case does not provide an independent evaluation or evidence that another plant should expect the same output gain, savings or payback. The useful lesson is the sequence: assess a repetitive task, involve technical support, try the system, and judge the purchase against observed performance.
Area 419: automated parts handling
NIST MEP reports that Area 419 faced labor-cost and labor-shortage concerns, ergonomic issues and a desire to improve spindle utilization. CIFT connected the company with robotics provider MetalCraft, helped assess opportunities and managed integration. Area 419 automated parts handling on a fifth-axis machine. Its operations vice president described maintaining one staffed shift while the machine ran for the remaining 16 hours of the day; within eight months, the company bought another machine with the same automation and hired an operator to manage the cell.

The case page lists $750,000 in cost savings, $500,000 in increased or retained sales, $2,530,000 in new investment and two increased or retained jobs. These are reported case figures, not a controlled causal estimate or a forecast for other manufacturers. The example also illustrates that automation can support investment and additional operating roles rather than simply replacing workers.
What can go wrong, and how can a project be corrected?
- The task is not stable enough. Frequent variation or changeovers can turn a nominally automatic cycle into repeated manual intervention. Reassess the task boundary, process consistency and flexibility requirements before committing.
- The equipment does not address the real bottleneck. If the next operation or material supply is limiting output, faster machine tending may not increase saleable production. Map the surrounding flow and target the actual constraint.
- Projected labor savings are not realized. A person may still be needed to tend, monitor or manage a cell, or employees may be redeployed instead of eliminated. Base the financial case on the staffing arrangement the plant intends to use.
- Integration and operating costs are underestimated. Include integration, maintenance and operating needs in the business case, then compare actual ongoing demands with the estimate.
- The process performs well only in a demonstration. Verify the result over representative production conditions, including ordinary interruptions and product changes, using the original baseline measures.
- Workers are not prepared for changed work. Include affected employees in planning and define training, safety and operating responsibilities before the cell goes live.
If results miss the target, separate a technology problem from a process, demand or integration problem. Check whether the baseline was realistic, the system is available when needed, the cell receives consistent inputs and output can flow downstream. Adjust the process or scope where evidence points to a specific cause; do not assume that buying additional equipment will fix a poorly understood constraint.
Where can manufacturers get implementation help?
NIST MEP says its experts can assess operations, recommend and prioritize opportunities, help build a business case tied to company strategy, connect manufacturers with integrators and vendors, and measure results. A local MEP center can be a starting point for determining what assistance is available in a manufacturer’s area. Qualified integrators can assess equipment and process interfaces; the Area 419 case is one example of a center coordinating with a robotics provider on a specific project.
