In a rapidly evolving business environment, organizations across India are constantly striving to improve productivity, reduce costs, and utilize their workforce more effectively. Whether it is a manufacturing plant, a warehouse operation, or a healthcare facility, understanding how time is actually spent on the shop floor is not optional — it is critical.
This is where Time Study Analysis, a core component of Time and Motion Study, plays a transformative role.
What Is Time Study Analysis?
Time Study Analysis is a systematic work measurement technique used to determine the time required for a qualified worker to perform a specific task under defined conditions and at a defined pace. Originally developed by Frederick Winslow Taylor and later refined through ILO (International Labour Organization) standards, it remains one of the most powerful tools in Industrial Engineering today.
When combined with Motion Study — which evaluates how a task is performed — it enables organizations to eliminate unnecessary movements, reduce operator fatigue, and optimize workflows end-to-end.
Key terminology:
• Observed Time – The actual time recorded during observation cycles
• Normal Time – Observed time adjusted by a performance rating factor
• Standard Time – Normal time + allowances (fatigue, personal, delay)
• Performance Rating – The observer’s assessment of worker pace versus a defined “normal” pace
Standard Time = Normal Time × (1 + Allowance Factor)
"This calculated Standard Time becomes the foundation for production planning, manpower deployment, and incentive design."
How Is a Time Study Analysis Conducted? (Step-by-Step)
Many companies understand the concept of time study but are unsure of the actual process. Here is how a structured time study is conducted at PMI:
- Define the Scope – Identify which operations, workstations, or processes are to be studied. Prioritize high-labor-cost or bottleneck areas first.
- Select and Brief the Operator – Choose a trained, experienced worker performing the task at a normal pace. Inform the operator about the study to avoid anxiety or behavioural changes.
- Break the Job into Elements – Divide the task into clear, measurable elements — each with a defined start and end point. This granularity makes it easier to spot where time is lost.
- Observe and Record Time – Using a stopwatch, video recording, or specialized software, record the time for each element across multiple cycles (typically 10–30 cycles depending on task variability).
- Apply Performance Rating – The trained observer rates the worker’s pace relative to a standard (e.g., 100 on the BSI scale). This adjusts observed time to a “normal” level.
- Calculate Normal Time and Standard Time – Apply the rating factor and add appropriate allowances (personal time, fatigue, unavoidable delays) to arrive at the Standard Time.
- Validate and Implement – Cross-verify standard times with supervisors, review for outliers, and integrate into production planning systems.
Key Reasons Why Companies Invest in Time Study Analysis
1. Improve Productivity and Operational Efficiency
One of the biggest reasons companies invest in time study analysis is to enhance productivity. By breaking down each activity into measurable elements, organizations can:
- Identify time-consuming or non-value-added (NVA) activities
- Reduce idle time and bottlenecks
- Balance workloads equitably across teams and shifts
For Indian manufacturing units and MSMEs, even a 5–10% productivity improvement can significantly impact annual profitability. In labor-intensive sectors, this often translates to crores of rupees saved annually.
2. Establish Accurate Standard Times
Without accurate standard times, businesses rely on assumptions — leading to unrealistic targets or underutilized capacity. A time and motion study helps organizations:
- Set fair and achievable performance standards based on data, not guesswork
- Plan manpower and shift schedules effectively
- Improve production planning, order commitment, and capacity utilization
In automotive and assembly-line environments, even a 1-minute deviation per cycle compounds to thousands of minutes lost across a production month.
3. Optimize Labor Utilization and Manpower Planning
Labor is one of the highest cost components in most organizations — often constituting 30–60% of total operating costs in manufacturing. Time study analysis enables:
- Optimal manpower deployment per shift
- Identification of overstaffing or understaffing across workstations
- Better alignment between workforce availability and production demand
In sectors like logistics, warehousing, and hospitals, this leads to higher labor efficiency without increasing headcount — a key lever for cost competitiveness.
4. Reduce Operational Costs
By systematically eliminating unnecessary motions, delays, and rework, companies consistently achieve:
- Reduction in direct labor costs
- Lower overtime dependency
- Minimized wastage of time, material, and energy
For cost-sensitive Indian industries — especially in Tier 2 and Tier 3 cities where margins are thin — time study analysis delivers a quick and measurable ROI.
5. Support Performance Management and Incentive Schemes
Organizations frequently struggle to design fair and defensible incentive plans. Time study provides a data-backed foundation for:
- Setting transparent performance benchmarks
- Designing equitable incentive and bonus structures
- Reducing disputes between management and the workforce
This builds trust and improves industrial relations — a factor of significant importance in Indian workplaces, especially where piece-rate or performance-linked pay is common.
6. Improve Process Design, Layout, and Ergonomics
Motion study focuses on how work is physically performed. When integrated with time study findings, it helps organizations:
- Redesign workstation layouts to minimize unnecessary reach, bend, or travel
- Reduce operator fatigue through better tool placement and sequencing
- Enhance workplace safety and ergonomic compliance
This is particularly relevant on factory floors, in warehouses with high manual handling, and in construction settings.
7. Enable Data-Driven Decision Making
Instead of relying on gut feeling or historical precedent, time study analysis provides quantifiable, auditable data that supports:
- Lean Manufacturing initiatives (identifying and eliminating the 8 wastes)
- Kaizen and Continuous Improvement programs
- Automation investment decisions — knowing exactly where human time is consumed helps justify ROI on machinery
8. Enhance On-Time Delivery and Customer Satisfaction
When internal processes become efficient and predictable:
- Delivery timelines improve and become more reliable
- Quality consistency increases due to standardized methods
- Service response times reduce in customer-facing operations
Ultimately, investing in time and motion study helps companies deliver better value to customers — whether B2B or B2C — while protecting margins.
Time Study vs. Other Work Measurement Techniques
Understanding where time study fits relative to other methods helps organizations choose the right approach:
| Technique | Best For | Accuracy | Time Required |
| Stopwatch Time Study | Repetitive, short-cycle tasks | High | Medium |
| PMTS Technique | Varied tasks, quick measurement | High | Low |
| MTM (Pre-determined) | New process design | Very High | High |
| Work Sampling | Long-cycle or irregular tasks | Medium | Low–Medium |
| Video Analysis | Remote or complex multi-motion tasks | High | Medium |
At PMI, we select the most appropriate technique based on task type, cycle time, and the client’s specific objectives — often combining methods for maximum insight.
Common Mistakes Companies Make Without Time Study
Many organizations unknowingly operate with significant inefficiencies simply because they have never measured work systematically. Common consequences include:
- Production targets set by tradition rather than actual capacity, leading to chronic under- or overproduction
- Manpower decisions made on intuition, resulting in misallocated headcount
- Incentive schemes that feel unfair because they are not anchored to measured performance
- Automation projects that deliver poor ROI because the actual time-cost of manual steps was never quantified
- Chronic overtime that masks deeper process inefficiencies instead of resolving them
A structured time study analysis surfaces these issues quickly and objectively.

Frequently Asked Questions
Time Study measures how long a task takes, while Motion Study analyses how a task is performed — the physical movements involved. When combined as Time and Motion Study, they provide a complete picture of both efficiency and method.
The number of observation cycles depends on the task's cycle time and variability. For short, repetitive tasks (under 2 minutes), 20–30 cycles are typically recommended. For longer tasks, 10–15 cycles may suffice. Statistical formulas based on desired confidence level and variability can calculate the precise minimum sample size.
A focused workstation time study can be completed in 2–5 days. A comprehensive plant-wide study covering multiple departments may take 3–6 weeks depending on scope, number of operations, and complexity.
When conducted by experienced practitioners, a time study has minimal disruption. Operators continue working normally; the observer simply records times without interfering with the workflow.
A fair day's work refers to the output expected from a qualified, motivated worker working at a normal pace (100 rating on the BSI scale) for a full shift, including all standard allowances. This concept underpins fair incentive design and performance standards.
