Why is work demand analysed in ergonomics?

Answer and explanation

Correct answer: To know how much force, time, attention and posture the task demands

Direct answer: A, to understand the force, time, attention and posture demanded by the task. Work demand analysis breaks a task into what the worker must physically and mentally do. It can include the force required, the duration and pace, repeated actions, visual or mental attention, reach distance and the posture that must be held. Designers can then compare these demands with human abilities and limitations and improve tools, layout, work methods or rest arrangements. A is correct because it covers the main kinds of demand that affect safety, comfort and performance. B is too narrow: preference may matter, but it is not the purpose of demand analysis. C and D have no connection with ergonomic assessment. Memory cue: first understand the task’s demands, then make the task fit the worker more safely.
