Time study stands as a cornerstone in the pursuit of operational excellence. It’s a rigorous work measurement technique. It’s dedicated to systematically recording the time required to complete specific tasks or operations.

The core aim is to establish standardized times, improve efficiency, optimize processes, and ultimately boost productivity. This section is dedicated to defining the crucial terms and concepts that form the bedrock of time study methodology. Clarifying these elements is essential for any professional looking to effectively implement and interpret time study data.

Defining Work Measurement

Work measurement is a broad field that encompasses all techniques used to determine the time required for a qualified worker to complete a specific task at a defined level of performance. It provides the data necessary for effective planning, scheduling, and control of operations. Time study is the most direct and widely used work measurement method.

Normal Time: Establishing a Baseline

Normal time represents the time needed for a qualified worker to complete a task at a normal pace, excluding any allowances for delays or personal needs. It serves as a baseline for calculating standard time.

Calculation of Normal Time

Normal time is derived from the observed time, which is the actual time recorded during the time study. This is adjusted using a rating factor.

The rating factor is a subjective assessment of the worker’s performance relative to a defined normal pace. The formula is:

Normal Time = Observed Time x Rating Factor

Standard Time: Accounting for Allowances

Standard time is the total time required to complete a task, including allowances for various factors. It’s the most realistic and useful time for planning and scheduling purposes.

Components of Standard Time

Standard time comprises normal time plus allowances for personal needs, fatigue, and unavoidable delays.

Standard Time = Normal Time + Allowances

Understanding Allowances

Allowances are critical adjustments to normal time, accounting for factors that inevitably impact a worker’s ability to maintain a consistent pace throughout the workday. Common types include:

• Personal Allowances: Time for restroom breaks, water, etc.
• Fatigue Allowances: Time to recover from physical or mental exertion.
• Delay Allowances: Time for unavoidable interruptions or equipment malfunctions.

Determining Allowance Values

Allowance values can be determined through work sampling studies, historical data analysis, or predetermined time systems.

Rating Factor/Pace Rating: Subjectivity and Accuracy

The rating factor, also known as pace rating, is a subjective assessment of a worker’s pace compared to what is considered a "normal" pace for the task. It’s crucial for normalizing observed times.

The Importance of Accurate Rating

Consistent and accurate rating is paramount to the reliability of a time study. Errors in rating can significantly skew the results and lead to inaccurate standards.

Therbligs: Deconstructing Motion

Therbligs, coined by Frank and Lillian Gilbreth, are a set of 18 fundamental hand motions used to analyze work tasks. Each therblig represents a basic element of motion, such as reach, grasp, move, and release.

Applying Therbligs for Method Improvement

By breaking down tasks into therbligs, analysts can identify inefficient motions. This allows for the redesign of workstations and processes to minimize wasted movement and improve overall efficiency.

Motion Study: Optimizing Human Movement

Motion study involves the systematic analysis of the movements involved in performing a task. The goal is to eliminate unnecessary motions.

It aims to simplify the work process and improve worker productivity. Motion study often utilizes techniques like micromotion analysis (using therbligs) and principles of motion economy. This all contributes to the creation of more efficient and ergonomic work methods.

Step-by-Step: How to Conduct a Time Study

With foundational knowledge established, the practical application of time study beckons.

This section outlines the methodology for conducting a time study. It offers a practical guide for carrying out the process effectively. It encompasses each stage, from defining objectives to meticulous documentation.

1. Defining Objectives: The Compass of Your Study

The bedrock of any successful time study lies in clearly defining its objectives.

What specific problem are you trying to solve? Are you aiming to optimize a process, establish a standard time, or identify areas for improvement?

A well-defined objective acts as your compass, guiding the entire study and ensuring its relevance.

Without a clear goal, your efforts may become aimless and unproductive.

• Example: "Determine the standard time for assembling a widget on production line #3."

2. Selecting the Subject: Choosing the Right Navigator

The choice of the subject, the worker being observed, is critical.

You aren’t looking for the fastest worker, nor the slowest.

Instead, select a representative and qualified worker who consistently performs the task at a normal pace.

This helps ensure that the resulting standard time is realistic and achievable for the majority of the workforce.

Consider their experience, skill level, and consistency.

3. Breaking Down the Task: Deconstructing the Complexity

Deconstruct the task into smaller, measurable elements.

Each element should be a distinct and easily identifiable step in the process.

This granular approach allows for a more detailed analysis and pinpointing of inefficiencies.

Avoid overly broad elements that obscure potential bottlenecks.

• Example: Instead of "Assemble Widget," break it down into: "Pick up Base," "Insert Component A," "Fasten Screw," etc.

4. Observing and Recording Time: Capturing the Essence of Time

This is where the rubber meets the road. It’s time to observe and record the time it takes the worker to perform each element of the task.

Tools of the Trade

Choose the right tools for the job. Options include:

Be consistent and methodical in your observations.

5. Determining the Rating Factor/Pace Rating: Calibrating the Performance

Pace rating is a critical and often subjective step.

Assess the worker’s performance level relative to what is considered a "normal" pace.

Is the worker performing faster or slower than normal?

The rating factor is a percentage that reflects this assessment.

• Example: A worker performing at a 10% faster pace would have a rating factor of 110% (or 1.1).

Strive for objectivity and consistency in your rating.

6. Calculating Normal Time: Adjusting for Performance

Normal time represents the time it would take a qualified worker to perform the task at a normal pace.

It is calculated by adjusting the observed time using the rating factor.

• Formula: Normal Time = Observed Time x Rating Factor

This step standardizes the time data. It accounts for variations in worker performance.

7. Applying Allowances: Accounting for the Inevitable

No worker can perform at peak efficiency without breaks.

Allowances are added to account for personal needs, fatigue, and unavoidable delays.

These allowances ensure that the standard time is realistic and sustainable.

Common allowances include:

• Personal Needs: Time for restroom breaks, water, etc.
• Fatigue: Time to recover from physical or mental exertion.
• Delays: Time for minor equipment malfunctions, material shortages, etc.

Allowance values are typically expressed as a percentage of the normal time.

8. Calculating Standard Time: The Final Equation

Standard time is the total time required to complete the task. This includes the normal time and all applicable allowances.

• Formula: Standard Time = Normal Time + (Normal Time x Allowance Factor)

This is the benchmark against which future performance will be measured.

It’s used for planning, scheduling, and cost estimation.

9. Documenting the Study: Preserving the Knowledge

Thorough documentation is paramount.
