BTM4773 METHOD STUDY BASIC CONCEPT C4

Analyze the differences between method study and work measurement. How do these two areas complement each other in improving productivity?

Answer explanation

Method study focuses on finding the best method to perform a task by analyzing and improving the work process, layout, tools, and motions. Work measurement determines the standard time required to perform that task using the best method identified through method study. They complement each other because method study improves how the work is done, while work measurement ensures efficiency by defining how long it should take, resulting in better productivity and resource utilization.

Explain how eliminating unnecessary body motions can lead to increased efficiency and reduced fatigue for workers. Provide an example to support your explanation.

Answer explanation

Eliminating unnecessary body motions reduces the physical effort required and minimizes wasted time, leading to increased efficiency and less fatigue. For example, if a worker bending repeatedly to pick up apples can use a height-adjustable table instead, it reduces the bending motion. This makes the task easier, prevents musculoskeletal strain, and allows the worker to maintain productivity for a longer time.

Compare the method study approach for two different tasks mentioned in the lecture: loading apples onto a conveyor belt and soldering in electronics. What key factors need to be considered for each task when developing the "one best method"?

Answer explanation

For loading apples, factors include ergonomics (worker posture), repetitive motion reduction, and material handling tools (like conveyor height). The focus is on minimizing physical strain and increasing speed.
For soldering in electronics, precision, steady hand movement, minimizing eye strain, and proper tool placement are critical. The focus is on accuracy and reducing errors, not just speed. Each task requires analyzing different human and machine interactions to find the best method.

Interpret the purpose of using charts like man-machine charts and string diagrams in method study. How do these tools help in analyzing and improving workflow?

Answer explanation

Man-machine charts display the interaction between workers and machines over time, identifying idle times and opportunities to balance workloads. String diagrams map the movement of materials or people, helping to analyze and reduce unnecessary travel or motion. Both tools visualize inefficiencies in workflows and guide redesign efforts to optimize processes and minimize wasted effort and time.

Examine the role of human factors in method study. Why is it important to consider ergonomics and worker safety when analyzing or redesigning a work method?

Answer explanation

Human factors ensure that the method is safe, comfortable, and minimizes fatigue for workers. Considering ergonomics reduces the risk of injuries like musculoskeletal disorders and improves worker productivity by making tasks easier to perform. A safe and ergonomically sound work method boosts morale, reduces absenteeism, and promotes sustainable efficiency in the long run.
