Nptel Work System Design week 3 solution




-: IMPORTANT NOTICE :-

Your answer is given in the explanation section, so please read carefully the explanation section for getting 100% in on the nptel assignment.

 Method study is concerned with the reduction of the work content and establishing the one best way of doing the job.

 True

 False


True.

Method study is a systematic approach to analyze, streamline, and improve work processes in order to reduce unnecessary work content, eliminate inefficiencies, and establish the most efficient and effective way of performing a job. The goal of method study is to identify the "one best way" of doing a job, which leads to improved productivity, better quality, and overall cost reduction. This concept is often associated with the field of industrial engineering and operations management.



Work study is a procedure oriented and systematic study.

 True

 False


True.

Work study is indeed a procedure-oriented and systematic study. It involves analyzing and improving work processes, methods, and procedures to enhance efficiency, productivity, and overall performance. Work study encompasses various techniques, including method study (which focuses on improving work methods) and time study (which involves measuring and analyzing the time required to perform tasks). The goal of work study is to optimize resources, reduce waste, and improve the overall effectiveness of work processes within an organization.



Choose the CORRECT sequence of steps involved in work study.

 Select-Record-Examine-Develop-Measure-Define-Install-Maintain

 Select-Record- Develop-Examine- Measure-Define-Install-Maintain

 Select-Record-Examine-Develop- Define-Measure- Install-Maintain

 Select-Record-Examine-Develop-Measure-Define- Maintain-Install


The correct sequence of steps involved in work study is:


Select - Record - Examine - Develop - Define - Measure - Install - Maintain


So, the correct option is:


Select-Record-Examine-Develop-Define-Measure-Install-Maintain



Reasons for excess work content (WC) is (are);

 Defects in design of a product

 Inefficient methods of manufacture

 Shortcomings of the management

 All of the above


All of the above.


Reasons for excess work content (WC) can indeed include defects in the design of a product, inefficient methods of manufacture, and shortcomings of the management. These factors can contribute to unnecessary or inefficient work processes, resulting in higher work content than necessary. Identifying and addressing these issues through methods like work study and process improvement can lead to reduced work content and improved overall efficiency.



Which of the following is (are) CORRECT?

 The actual time required to complete an operation, or a job is more than the basic time in practical situations.

 Excess time = Time due to defects in design or specification of the product + Time due to inefficient methods of manufacture or operation.

 Basic work content is the irreducible minimum time theoretically required to produce one unit of output.

 All of the above


All of the above.


The actual time required to complete an operation or job is often more than the basic time in practical situations due to various factors such as interruptions, variations, and external influences.

Excess time can indeed be calculated as the sum of time due to defects in the design or specification of the product, along with time due to inefficient methods of manufacture or operation. This excess time represents inefficiencies that can be addressed to improve the overall process.

Basic work content refers to the irreducible minimum time theoretically required to produce one unit of output. It represents the most efficient time possible under ideal conditions.


So, all three statements provided are correct.


Work content added by defects in design (specifications) of the product is due to;

 Bad design of product

 Selection of wrong tools

 Bad layout causing waste movement

 Operative’s bad working method


Bad design of product.

Work content added by defects in the design or specifications of a product refers to the additional time or effort required to complete a task due to flaws or shortcomings in the design itself. This can include factors such as inefficient product shapes, sizes, features, or characteristics that make the manufacturing or operational process more complex, time-consuming, or difficult. Therefore, the primary reason for work content added by defects in design is indeed a "bad design of the product." The other options listed can contribute to inefficiencies as well but are not specifically related to defects in design.


Work content added by defects in design (specifications) of the product is due to;

 Bad design of product

 Selection of wrong tools

 Bad layout causing waste movement

 Operative’s bad working method

Work content added by defects in design (specifications) of the product is due to:


Bad design of product.

Defects in the design or specifications of a product can lead to inefficiencies and additional work content during manufacturing or operational processes. These defects might require extra time, effort, or resources to overcome, resulting in increased work content. The other options mentioned (selection of wrong tools, bad layout causing waste movement, operative's bad working method) can also contribute to inefficiencies, but they are not directly related to defects in the design or specifications of the product.






Consider the following statements:
1. Method study refers to the estimation of standard time, that is the time allowed for completing the job using the given method.
2. Work measurement is the systematic recording and critical examination of existing and proposed ways of doing work.

 Both 1 and 2 are correct.

 Only 1 is correct.

 Both 1 and 2 are incorrect.

 Only 2 is correct.


Only 2 is correct.


Method study is not primarily concerned with the estimation of standard time. It is about analyzing and improving work methods to increase efficiency. Standard time estimation is more closely related to work measurement.

Work measurement does involve the systematic recording and critical examination of existing and proposed ways of doing work to determine the standard time required for a task.


So, the correct option is: Only 2 is correct.


Which of the following is (are) measures of employee’s performance?

 Quantity of performance

 Quality of output

 Both a and b

 None of the above


Both a and b.

The quantity of performance (output) and the quality of output are both important measures of an employee's performance. Quantity measures how much work or output an employee produces, while quality measures the level of excellence or accuracy in the output. Therefore, both quantity and quality are commonly used as performance metrics to assess an employee's effectiveness and contribution to the organization.


The basic procedure for work measurement, regardless of a particular technique is comprised of;

 Analyzing the work

 Measuring the work

 Synthesizing the work

 All of the above


All of the above.

The basic procedure for work measurement, regardless of the specific technique being used, typically involves:

Analyzing the work: This step involves studying and understanding the tasks and activities involved in a particular job or process. It includes breaking down the work into its constituent elements, identifying different methods or steps, and examining the sequence of actions.

Measuring the work: In this step, the time required to perform each element of the job or process is measured. This measurement can be done using various techniques, such as time study, predetermined motion time systems, or work sampling.

Synthesizing the work: After measuring the individual elements, the data is synthesized or combined to calculate the total time required for the entire job or process. This may involve summing up the times for each element or using appropriate mathematical formulas.

Therefore, all three steps—analyzing the work, measuring the work, and synthesizing the work—are part of the basic procedure for work measurement.


The hostile attitude of supervisor may be the most difficult problem for the work study analyst.

 True

 False


True.

The hostile attitude of a supervisor can indeed pose a significant challenge for a work study analyst. A hostile or resistant supervisor may create obstacles to the implementation of work study techniques, hinder data collection, and impede the process of making changes based on the study's recommendations. Effective communication, collaboration, and cooperation with all levels of management, including supervisors, are crucial for the successful implementation of work study projects and the realization of their benefits.
