A time-and-motion study in a warehouse is essentially breaking a process into repeatable steps, measuring how long each step takes, identifying wasted motion, and then redesigning the process around a safer, faster standard.
Here’s a practical way an operations analyst would do it.
Start with a narrowly defined process, such as:
Define the metric you're trying to improve. For example:
Objective: Reduce average order-picking time from 8.0 minutes per order while maintaining accuracy and safety. Also establish the relevant constraints—order mix, SKU characteristics, staffing, equipment, shift, and expected service level.
Break the job into discrete elements.
For example, an order-picking cycle might be:
Don't just measure the overall cycle. Measure the individual elements, because that's how you discover where time is being lost.
A useful observation sheet might look like:
| Element | Time | Distance | Value-added? | Problem observed |
|---|---|---|---|---|
| Travel to SKU | 22 sec | 45 ft | No | Long travel |
| Locate SKU | 8 sec | — | No | Poor labeling |
| Pick item | 6 sec | — | Yes | — |
| Scan | 4 sec | — | Necessary | — |
| Place in tote | 5 sec | — | Yes | — |
| Travel to next SKU | 31 sec | 65 ft | No | Poor slotting |
Don't base the standard on one unusually fast or slow cycle.
Observe multiple cycles across different workers, times of day, and representative order types. OSHA's technical guidance, for example, recommends documenting tasks systematically and notes that around 10 cycles can be useful for short repetitive jobs, while longer-cycle jobs may require fewer cycles if the task is captured adequately.
For warehouse analysis, I'd typically collect data such as:
The goal is to distinguish normal process variation from actual waste.
This is where the "motion" part becomes important.
Look for:
For example, suppose a picker spends:
40% traveling + 15% searching + 20% picking + 10% scanning + 15% other.
Increasing the worker's picking speed won't address the biggest problem. Reducing travel and search time probably has much greater potential.
OSHA specifically recommends reducing unnecessary travel/reach, minimizing load weight and range of motion, and using conveyors or carts for horizontal movement where appropriate.
Calculate metrics such as:
Average cycle time
Average Cycle Time=Total observed timeNumber of cycles\text{Average Cycle Time} = \frac{\text{Total observed time}}{\text{Number of cycles}}
And productivity:
Units per Labor Hour=Units processedLabor hours\text{Units per Labor Hour} = \frac{\text{Units processed}}{\text{Labor hours}}
For example:
This gives you a measurable starting point.
Don't automatically conclude that the worker is the problem.
Suppose your study shows that an employee spends 25 seconds searching for a SKU. Investigate why:
This distinction is crucial: time-and-motion analysis should improve the system, not simply demand that people work faster.
NIOSH recommends breaking jobs into tasks/actions and considering factors such as frequency, duration, workstation layout, reach distance, and work posture.
Common warehouse interventions include:
Move high-frequency SKUs closer to the packing/shipping area and put frequently picked products in ergonomic locations.
Reduce unnecessary travel and congestion.
Define the most efficient repeatable sequence for the task.
Consider improvements such as:
Reposition products, workstations, or equipment to reduce bending, reaching, twisting, and excessive force.
This isn't merely a safety consideration. OSHA notes that ergonomic improvements can reduce fatigue and injuries while also improving productivity.
Don't immediately roll the new method out to the entire warehouse.
Run a pilot:
Before
After pilot
Then check whether the improvement survives normal operating conditions—not just a carefully controlled trial.
Also verify that productivity improvements haven't increased fatigue, injury risk, errors, or equipment congestion. OSHA specifically cautions that repetitive motions, awkward postures, heavy lifting, and fast work pace can create ergonomic risks.
Once validated, document the improved method:
Standard work example
Pick assignment → travel to location → scan location → retrieve SKU → scan SKU → place in tote → confirm quantity → proceed to next location. Then establish an expected cycle time or labor standard based on representative observations rather than simply taking the fastest observed worker's performance.
A useful standard should account for normal variation, unavoidable delays, fatigue/recovery, and the actual mix of work. Historical labor standards can otherwise embed existing inefficiencies.
After implementation, track:
Then compare the before vs. after performance.
Imagine a warehouse picker currently processes 80 order lines/hour.
The study finds:
The analyst discovers that 20% of the frequently picked SKUs are located far from packing.
After a slotting redesign, the average travel component falls from 34 to 24 minutes/hour.
The important insight isn't simply:
"The picker needs to move faster." It's:
"The process is consuming too much labor on travel; changing SKU locations can remove that work without increasing worker pace." That's the fundamental mindset of a good operations analyst: measure the work, understand why the time is being spent, eliminate unnecessary work, standardize the improved method, and then verify that the improvement is sustainable. Worker participation is also valuable; OSHA recommends involving workers in identifying hazards and developing/evaluating solutions.
If you're doing this as an operations analyst interview/case study, I can also give you a realistic warehouse time-and-motion dataset and walk through the calculations, Excel analysis, and recommendations step by step.

A time and motion study in a warehouse is a structured way for an operations analyst to measure how work is actually performed, identify wasted time and movement, and then redesign the process around a safer, faster, repeatable method. Lean standardized work specifically combines work sequence, manual time, walking time, and processing time to identify waste and establish a baseline for improvement.
Start with a specific process rather than studying the entire warehouse.
Examples:
Define the improvement question, such as:
"Why does it take 8.5 minutes on average to pick a 20-line order, and how can we reduce that without increasing errors or injuries?" Establish baseline KPIs such as:
Go to the warehouse floor—the "gemba"—and observe several employees performing the task.
Don't immediately assume the documented procedure represents actual work. Record what really happens, including:
For example, a picking cycle might be broken into:
| Element | Time |
|---|---|
| Receive assignment | 8 sec |
| Walk to location A | 22 sec |
| Search for SKU | 15 sec |
| Pick item | 6 sec |
| Scan | 4 sec |
| Walk to location B | 18 sec |
| Pick/scan | 12 sec |
| Waiting/congestion | 20 sec |
| Total | 105 sec |
The important insight is that "picking" may represent only a small fraction of total elapsed time.
Don't base the standard on one unusually fast or slow employee.
Measure multiple cycles across:
A spreadsheet or time-study app can capture:
Date | Employee | Task | Element | Start | End | Quantity | Exception | Notes
You can then calculate average, median, minimum, maximum, and variation.
For highly variable work, stratify the data rather than blindly averaging everything together. A single large order, for example, shouldn't necessarily be compared with a two-item order.
Classify each element.
Typical warehouse waste includes:
This is often where the biggest opportunities appear. A few seconds saved on each movement can accumulate into hours of labor savings across multiple shifts.
Time alone doesn't explain why the work takes that long.
Map the employee's movement through the warehouse. For example:
Pick → walk 40 ft → scan → walk 25 ft → pick → return 40 ft → stage
Then ask:
For example, reducing a picker’s average travel from 1,200 ft/order to 800 ft/order can have a much larger effect than shaving one second off the physical picking motion.
A common mistake is to define the "best" method simply as the fastest method.
It also needs to be safe and sustainable. OSHA identifies warehouse risks including repetitive motions, bending, reaching, lifting/lowering, pushing/pulling, awkward postures, and excessive pace.
So during the study, record:
For example, moving high-volume items toward standing/elbow height can improve both ergonomics and productivity.
Importantly, don't use the study to force workers to take unsafe shortcuts. OSHA specifically cautions against production standards that encourage practices such as reaching across pallets rather than accessing them safely.
Now redesign the process using the data.
Suppose the original process is:
Pick → walk → search → pick → walk → scan → wait → stage The improved process might be:
Optimized pick route → scan while picking → consolidated tote → direct staging Potential improvements could include:
Lean's standardized-work approach explicitly considers manual work, walking, and machine-processing time together, which is particularly useful for this kind of analysis.
Once the improved process is proven, document the new method.
For example:
Current state
Future state
The new standard should specify the sequence, expected cycle time, required equipment/materials, quality checks, and safety requirements.
Standardized work provides a repeatable baseline that can then be continuously improved rather than repeatedly reinventing the process.
Test the proposed method in one zone or with a small group.
Compare:
Before vs. after
Don't declare success merely because the stopwatch says the task is faster. If productivity improves 10% but picking errors increase 5%, the change may actually make the operation worse.
Suppose a warehouse performs:
Savings:
5 sec × 10,000 = 50,000 seconds/day
That's approximately:
13.9 labor-hours/day
At $25/hour fully loaded labor cost:
13.9 × $25 ≈ $347/day
Over 250 operating days:
≈ $86,800/year
That gives management a concrete basis for deciding whether the improvement is worth implementing.
A good operations analyst can essentially follow this sequence:
Define → Observe → Break into elements → Time → Map motion → Identify waste → Analyze ergonomics → Redesign → Pilot → Standardize → Measure again
The key mindset is not "How fast can we make employees work?" It's:
"How can we design the process so employees can accomplish the required work with less unnecessary motion, waiting, handling, and risk?" That distinction matters. Lean's modern approach treats standardized work as a baseline for employee participation and continuous improvement rather than simply imposing a rigid "one best way."

A warehouse **time and motion study** is essentially a structured way to answer two questions: 1. **Where is time being spent?** 2. **Which movements or process steps can be eliminated, combined, rearranged, or simplified?**
A warehouse time and motion study is essentially a structured way to answer two questions:
An operations analyst would typically run it like this:
Start with a specific process rather than studying the entire warehouse.
Examples:
Define a measurable goal, such as:
“Reduce average pick time per order by 15% without increasing errors or injury risk.” This prevents the study from becoming simply an exercise in watching employees work.
Document the process from beginning to end.
For example, an order-picking cycle might be:
Receive pick → Travel to location → Locate SKU → Reach/bend → Pick item → Scan → Place in tote → Travel to next location
Then break each activity into measurable work elements with clear start and stop points. This is a standard principle of time study.
The analyst should also record things such as:
The analyst observes multiple workers performing the same task under normal operating conditions.
A simple data sheet might look like:
| Element | Time |
|---|---|
| Walk to location | 18 sec |
| Locate SKU | 7 sec |
| Reach/pick | 5 sec |
| Scan | 3 sec |
| Place item | 4 sec |
| Walk to next location | 15 sec |
| Total | 52 sec |
Don't base the conclusion on one employee or one cycle. Observe enough cycles and, where practical, multiple experienced workers. The U.S. Department of Labor's guidance on time studies similarly emphasizes experienced workers, representative conditions, repeat observations, and documenting the method.
This is where the motion-study component becomes valuable.
Look for:
For example, you might discover that a picker spends 25% of the cycle walking and only 40% actually handling product. That suggests the solution may be slotting/layout optimization rather than simply asking the worker to pick faster.
A useful framework is ECRS:
For example:
Before: Picker walks 30 ft → picks SKU → walks 30 ft back → scans → places item.
Potential improvement: Move the scanner/slot arrangement so the item can be picked and scanned at the same position.
A warehouse case study applying time/motion analysis alongside ECRS found that identifying bottlenecks in activities such as put-away and stamping enabled substantial resource and cost reductions.
Once the best practical work method has been identified, calculate the expected time under normal operating conditions.
Conceptually:
Observed time → performance adjustment → allowances → standard time
The standard shouldn't represent an employee working at an unsustainable maximum speed. It should reflect a repeatable method that a properly trained worker can maintain.
For example:
That can then become a labor-planning input.
Don't optimize every activity equally.
Calculate the contribution of each activity to total labor time:
| Activity | % of total time |
|---|---|
| Walking | 38% |
| Searching | 15% |
| Picking | 22% |
| Scanning | 8% |
| Handling/placing | 12% |
| Waiting | 5% |
Here, walking + searching = 53%. That's where the analyst should concentrate improvement efforts.
Typical interventions could include:
Efficiency cannot simply mean making people move faster.
Warehouse work commonly involves lifting, bending, reaching, pushing/pulling, awkward postures and repetitive motion. OSHA specifically recommends designing material-handling tasks to minimize weight, range of motion and frequency, and reducing the distance between workers and the materials they handle.
So if the study discovers that moving a SKU closer saves 5 seconds but requires employees to repeatedly lift it from floor level, that's not automatically a good improvement.
The better solution might be to change the storage height or workstation design.
Before rolling out a new standard, test it in a controlled area.
For example:
Baseline
Pilot
After
The improvement is only successful if productivity increases without unacceptable effects on quality, safety, or employee fatigue.
Once validated, document the new process as standard work and track KPIs such as:
Then periodically repeat the study because warehouse volume, SKU mix, technology and layouts change.
Observe → Measure → Break into elements → Identify waste → Redesign → Pilot → Measure again → Standardize → Monitor
The key mindset is: don't use time-and-motion studies merely to make workers work faster. Use them to redesign the system so workers have less unnecessary work to do. That distinction is particularly important in warehouses, where better ergonomics can support both productivity and injury reduction.
If you're learning this for an operations analyst interview, I can also show you a realistic warehouse time-and-motion case study and walk through the calculations step by step.

Conducting a time and motion study in a warehouse environment involves breaking down operational tasks into distinct components, measuring the time required to perform them, and analyzing the motion to eliminate waste and bottlenecks.
Here is how an operations analyst typically executes this process:
- Define the specific warehouse process to analyze (e.g., order picking, put-away, packing, or receiving).
- Establish clear baseline metrics and goals, such as reducing cycle time per order or increasing units processed per hour.
- Observe the current workflow without interference to map out the exact sequence of steps.
- Break the process down into discrete, measurable micro-elements (e.g., walking to a shelf, scanning an item, lifting the item, placing it in a tote).
- Record the time taken for each micro-element across multiple cycles and operators to account for variance.
- Document ergonomic factors, physical movements, and travel paths (often using spaghetti diagrams to track floor movement).
- Adjust the raw observed times by applying a performance rating factor to account for operator pace (normalizing above- or below-average speeds).
- Add standard allowances for fatigue, personal needs, and unavoidable delays to arrive at a true **Standard Time** for the task.
- Analyze the collected data using 100% - Value-Add Percentage to isolate non-value-added activities like excessive walking, searching, or double-handling.
- Compare actual performance against target benchmarks or standard operating procedures (SOPs).
- Propose layout changes, slotting optimizations (placing high-frequency items closer to packing stations), or automation aids to minimize wasteful motion.
- Redefine the standard operating procedure to reflect the streamlined workflow.
- Train warehouse staff on the new standardized methods and explain the "why" behind the changes to secure buy-in.
- Monitor post-implementation key performance indicators (KPIs) to verify efficiency gains and adjust as needed.

A **time and motion study** in a warehouse is a structured way to measure how work is actually performed, identify wasted time or movement, and then redesign the process to improve throughput, cost, and safety. An operations analyst would typically follow this process: ## 1. Define the objective
A time and motion study in a warehouse is a structured way to measure how work is actually performed, identify wasted time or movement, and then redesign the process to improve throughput, cost, and safety.
An operations analyst would typically follow this process:
Start with a specific problem rather than studying the entire warehouse.
Examples:
Establish the key metrics beforehand, such as:
Units/hour = Units processed ÷ Labor hours
Cycle time = Time to complete one work cycle
Labor utilization = Productive labor time ÷ Available labor time
Break the operation into individual steps.
For example, an order-picking cycle might be:
The analyst should distinguish between value-added work and activities such as walking, waiting, searching, re-handling, equipment delays, and paperwork.
The analyst observes multiple employees performing the same job under normal operating conditions. A stopwatch, WMS data, barcode scans, or video can be used.
For each cycle, record things such as:
| Element | Time |
|---|---|
| Travel to location | 18 sec |
| Locate product | 7 sec |
| Pick item | 5 sec |
| Scan | 3 sec |
| Place in tote | 4 sec |
| Waiting | 8 sec |
| Total | 45 sec |
Don't base the standard on one unusually fast or slow cycle. OSHA's ergonomics guidance specifically recommends observing representative work and notes that video can be useful for breaking tasks into individual elements.
Measure multiple cycles across different conditions:
This helps distinguish normal process variation from genuine inefficiency.
For example, suppose 50 picking cycles produce:
That immediately tells the analyst where to investigate.
This is the part that makes it a time-and-motion study rather than simply a stopwatch exercise.
Look for:
For example, you might discover that a picker spends only 20 seconds actually picking an order but 32 seconds walking and searching.
The solution may therefore be layout optimization, not asking the worker to pick faster.
Ergonomics matters here too: OSHA identifies bending, reaching, lifting, pushing/pulling, awkward postures, and repetitive work as important warehouse risk factors.
A useful technique is to classify lost time into categories:
Travel + Search + Handling + Waiting + Rework + Actual processing
Suppose a picker spends 60 seconds per order:
The analyst should ask why each non-value-added activity occurs.
For example:
Why is walking 25 seconds? → SKUs are widely dispersed. Why are SKUs dispersed? → Slotting is based primarily on available space. Why not frequency? → The warehouse isn't using recent order-history data for slotting. Now the improvement opportunity becomes much clearer.
Typical warehouse improvements include:
OSHA specifically recommends engineering changes that reduce range of motion, weight, frequency, awkward postures, and distance between workers and materials.
Suppose the study finds that the average picker spends 60 seconds/order.
After redesign:
New cycle time = 40 seconds
That's a 33% reduction in cycle time and theoretically increases capacity from:
60 ÷ 60 = 1 order/minute
to:
60 ÷ 40 = 1.5 orders/minute
The analyst would then translate this into annual labor capacity, staffing requirements, overtime reduction, or throughput improvement.
Don't immediately redesign the entire warehouse.
Test the proposed change in one zone, shift, or process.
Compare:
Worker involvement is particularly valuable because employees often know the practical causes of delays that aren't obvious from data alone. OSHA recommends involving workers directly in workplace assessments and solution development.
Once the new method proves effective:
The important point is that the study shouldn't become a way of simply demanding that workers move faster. A good analyst uses the data to remove unnecessary work from the process while protecting safety and quality. OSHA notes that effective ergonomic improvements can reduce physical demands while also improving productivity.
Observe → Measure → Break into elements → Find waste → Identify root causes → Redesign → Pilot → Measure again → Standardize
In practice, the strongest time-and-motion studies combine stopwatch/WMS data + direct observation + employee input + process mapping + ergonomic analysis. That gives the operations analyst a much better basis for improving warehouse efficiency than relying on productivity numbers alone.
