What is the primary objective of Work Study?

  1. To increase productivity

  2. To reduce costs

  3. To improve quality

  4. To enhance safety

Show answer
Correct Option: A
Explanation:

Work Study aims to increase productivity by analyzing and improving work methods, processes, and systems.

What are the two main branches of Work Study?

  1. Method Study and Time Study

  2. Motion Study and Time Study

  3. Motion Study and Method Study

  4. Time Study and Ergonomics

Show answer
Correct Option: A
Explanation:

Work Study consists of two main branches: Method Study, which focuses on improving work methods, and Time Study, which focuses on measuring and analyzing work time.

What is the purpose of Motion Study?

  1. To identify and eliminate unnecessary motions

  2. To determine the most efficient sequence of motions

  3. To measure the time required for each motion

  4. To analyze the workplace layout

Show answer
Correct Option: A
Explanation:

Motion Study aims to identify and eliminate unnecessary motions, simplify necessary motions, and combine motions to improve efficiency.

What is the purpose of Time Study?

  1. To determine the standard time for a task

  2. To analyze the work content of a task

  3. To identify and eliminate bottlenecks

  4. To improve the workplace layout

Show answer
Correct Option: A
Explanation:

Time Study aims to determine the standard time required to complete a task under specified conditions, considering allowances for rest and personal needs.

What is the difference between a standard time and a normal time?

  1. Standard time includes allowances for rest and personal needs, while normal time does not.

  2. Standard time is based on the performance of an average worker, while normal time is based on the performance of a skilled worker.

  3. Standard time is used for setting production targets, while normal time is used for calculating labor costs.

  4. Standard time is determined through Time Study, while normal time is determined through Motion Study.

Show answer
Correct Option: A
Explanation:

Standard time includes allowances for rest and personal needs, while normal time represents the time required to complete a task without any allowances.

What is the role of Ergonomics in Work Study?

  1. To design workplaces and tasks that fit the human body and capabilities

  2. To reduce the risk of work-related injuries and illnesses

  3. To improve productivity and efficiency

  4. To enhance job satisfaction and motivation

Show answer
Correct Option: A
Explanation:

Ergonomics in Work Study focuses on designing workplaces and tasks that fit the human body and capabilities, considering factors such as posture, reach, and physical demands.

What is the purpose of a work sampling study?

  1. To estimate the proportion of time spent on different activities

  2. To determine the standard time for a task

  3. To identify and eliminate unnecessary motions

  4. To analyze the workplace layout

Show answer
Correct Option: A
Explanation:

Work sampling studies involve observing and recording the activities of workers over a period of time to estimate the proportion of time spent on different activities.

What is the difference between a flow process chart and a flow diagram?

  1. A flow process chart shows the sequence of operations, while a flow diagram shows the sequence of materials.

  2. A flow process chart uses symbols to represent operations, while a flow diagram uses symbols to represent materials.

  3. A flow process chart is used for analyzing production processes, while a flow diagram is used for analyzing material handling processes.

  4. A flow process chart is more detailed than a flow diagram.

Show answer
Correct Option: A
Explanation:

A flow process chart shows the sequence of operations involved in a process, while a flow diagram shows the sequence of materials or information through a process.

What is the purpose of a multiple activity chart?

  1. To record the activities of multiple workers simultaneously

  2. To determine the standard time for a task

  3. To identify and eliminate unnecessary motions

  4. To analyze the workplace layout

Show answer
Correct Option: A
Explanation:

A multiple activity chart is used to record the activities of multiple workers simultaneously, allowing for the analysis of interactions and idle time.

What is the role of predetermined motion time systems (PMTS) in Work Study?

  1. To establish standard times for basic motions

  2. To determine the standard time for a task

  3. To identify and eliminate unnecessary motions

  4. To analyze the workplace layout

Show answer
Correct Option: A
Explanation:

Predetermined motion time systems (PMTS) provide standard times for basic motions, allowing for the rapid determination of standard times for complex tasks.

What is the purpose of a work measurement study?

  1. To determine the standard time for a task

  2. To analyze the work content of a task

  3. To identify and eliminate bottlenecks

  4. To improve the workplace layout

Show answer
Correct Option: A
Explanation:

Work measurement studies aim to determine the standard time required to complete a task under specified conditions, considering allowances for rest and personal needs.

What is the difference between a time study and a work sampling study?

  1. Time study involves continuous observation of a worker, while work sampling involves intermittent observations.

  2. Time study is used to determine the standard time for a task, while work sampling is used to estimate the proportion of time spent on different activities.

  3. Time study is more accurate than work sampling.

  4. Time study is more time-consuming than work sampling.

Show answer
Correct Option: A
Explanation:

Time study involves continuous observation of a worker to measure the time taken to complete a task, while work sampling involves intermittent observations to estimate the proportion of time spent on different activities.

What is the role of statistical methods in Work Study?

  1. To analyze data collected during work studies

  2. To determine the standard time for a task

  3. To identify and eliminate bottlenecks

  4. To improve the workplace layout

Show answer
Correct Option: A
Explanation:

Statistical methods are used to analyze data collected during work studies, such as time study data and work sampling data, to draw meaningful conclusions and make informed decisions.

What is the purpose of a workplace layout study?

  1. To design an efficient and effective workplace layout

  2. To determine the standard time for a task

  3. To identify and eliminate bottlenecks

  4. To improve the workplace environment

Show answer
Correct Option: A
Explanation:

Workplace layout studies aim to design an efficient and effective workplace layout that minimizes material handling, improves workflow, and enhances productivity.

What is the difference between a process chart and a flow diagram?

  1. A process chart shows the sequence of operations, while a flow diagram shows the sequence of materials.

  2. A process chart uses symbols to represent operations, while a flow diagram uses symbols to represent materials.

  3. A process chart is used for analyzing production processes, while a flow diagram is used for analyzing material handling processes.

  4. A process chart is more detailed than a flow diagram.

Show answer
Correct Option: A
Explanation:

A process chart shows the sequence of operations involved in a process, while a flow diagram shows the sequence of materials or information through a process.
