Which type of information will be most useful for deciding ergonomic improvement priority?

Correct answer: How many people are affected, how serious the risk is and how feasible the improvement is

The direct answer is option A: the number of affected people, seriousness of risk and feasibility of improvement are most useful. Ergonomic priority means deciding which problem should be addressed first. Start by measuring how many workers are affected. Then judge the possible harm, such as pain, injury risk or loss of ability to work. Finally consider whether a practical improvement can be made with available time, equipment and money. Option A is correct because it combines impact, urgency and realistic action. Option B is wrong because wall colour and curtain price do not measure ergonomic risk. Option C is wrong because an employee’s nickname is unrelated to safety evidence. Option D is wrong because decoration style does not show who is at risk or how serious the problem is. A good decision uses relevant data rather than personal preference. Memory cue: priority depends on people affected, risk severity and workable solution.
