Key Concepts and Principles

Work Measurement Techniques

There are various techniques used in work measurement, but two of the most commonly used ones are time study and work sampling.

Time Study

Time study is a technique used to determine the standard time required to perform a task. It involves the following steps:

1. Select the task to be studied
2. Observe and record the time taken to perform the task
3. Analyze the data and calculate the average time
4. Adjust the average time for any allowances or rating factors
5. Calculate the standard time for the task

Work Sampling

Work sampling is a technique used to estimate the proportion of time spent on different activities. It involves the following steps:

1. Define the study objectives and select the activities to be observed
2. Determine the sample size and sampling frequency
3. Observe and record the activities performed during the sampling period
4. Analyze the data and calculate the work sampling results

Need for Work Measurement

Work measurement is essential for various reasons, including:

• Efficiency improvement: By identifying and eliminating unnecessary or inefficient work methods, work measurement helps improve overall efficiency.
• Resource allocation: Work measurement provides valuable information for allocating resources effectively, ensuring that the right amount of resources is allocated to each task.
• Cost reduction: By identifying areas of inefficiency and streamlining work processes, work measurement helps reduce costs.

Confidence Levels and Sample Size Determinations

Confidence levels and sample size determinations are crucial aspects of work measurement studies. Confidence levels refer to the level of certainty or confidence in the accuracy of the results obtained from a study. Sample size determinations involve calculating the number of observations or samples required to achieve a desired level of confidence.

Step-by-Step Walkthrough of Typical Problems and Solutions

To better understand work measurement, let's walk through a typical problem and its solution using time study.

Problem: Determining the Standard Time for a Specific Task Using Time Study

1. Step 1: Select the task to be studied

In this step, you need to choose the specific task or activity that you want to measure the time for. It is important to select a representative task that is commonly performed and has a significant impact on overall productivity.

1. Step 2: Observe and record the time taken to perform the task

In this step, you need to observe the task being performed and record the time taken for each cycle or repetition. It is important to record the time accurately and consistently.

1. Step 3: Analyze the data and calculate the average time

Once you have collected the data, you need to analyze it and calculate the average time taken to perform the task. This can be done by summing up the recorded times and dividing by the number of observations.

1. Step 4: Adjust the average time for any allowances or rating factors

In this step, you need to adjust the average time for any allowances or rating factors that may affect the standard time. This could include factors such as fatigue, personal needs, or unavoidable delays.

1. Step 5: Calculate the standard time for the task

Finally, you can calculate the standard time for the task by adding the adjusted average time to any predetermined allowances or rating factors.

Solution: Example Problem Solving Using Time Study

Let's consider an example problem to illustrate the application of time study in determining the standard time for a specific task.

Problem: Determine the standard time for assembling a product.

1. Step 1: Select the task to be studied

In this case, the task is the assembly of a product.

1. Step 2: Observe and record the time taken to perform the task

The time taken for each assembly cycle is recorded as follows:

Cycle 1: 10 minutes Cycle 2: 12 minutes Cycle 3: 11 minutes

1. Step 3: Analyze the data and calculate the average time

The average time is calculated by summing up the recorded times and dividing by the number of observations:

Average time = (10 + 12 + 11) / 3 = 11 minutes

1. Step 4: Adjust the average time for any allowances or rating factors

In this case, no allowances or rating factors are applicable.

1. Step 5: Calculate the standard time for the task

The standard time is calculated by adding the adjusted average time to any predetermined allowances or rating factors. In this case, the standard time is equal to the average time:

Standard time = 11 minutes
