Work simplification by changes in hand and body motions can be achieved by the following -

Correct option is A

Work simplification often involves improving the efficiency of work processes, and improving the sequence of work is one way to achieve this. By organizing tasks in a more logical order, unnecessary movements or steps can be eliminated, leading to reduced physical effort and improved productivity.
Information Booster: Work simplification is a key principle in industrial engineering and ergonomics. By analyzing and improving the sequence of steps in a task, unnecessary hand and body motions can be eliminated, resulting in faster and less strenuous work processes. Other techniques for work simplification include reorganizing workflows, automating tasks, and reducing non-value-added activities.
Additional Knowledge:
· Changing the product: Changing the product itself may not necessarily simplify work motions unless the change leads to easier handling or processing.
· Changing in equipment: New equipment can enhance efficiency but does not directly simplify hand or body motions unless it's specifically designed to do so.
· Changing in storage space: While organizing storage space can improve overall workflow, it does not directly simplify work motions as effectively as improving the sequence of work.
